My review (in French) of the Vagabond from Hacker Model has been published in the december issue of RC-Pilot (http://www.rcpilot-online.com/).



RC Soaring Digest, december issue

Image
I forgot to relay the information that the december issue of RC Soaring Digest is available. It is very large with many articles and includes my report about the F3F worldchampionship in Donovaly and the review of the Vagabond from Hacker Model.

Video: Fly in Iceland

Filmed with a quadricopter (TBS discovery pro) by Thibaud Ringenbach, who is also a F3F pilot. Behind this 5:40s, they are  41 flights corresponding to 7 hours in the air, "only" 85Gb of data and 4 month of editing.

The result is this hauntingly beautiful video !


A world premiere ?

Image
Thierry Monnot 3D printed the fuselage master of his new VTPR plane called the Minilimande. After many hours of printing, and a cost of 40 euros of material, Thierry obtained this multipart fuselage.


The approach is very innovative, for a super result. The rest of the work remains usual with sanding, gelcoat before to obtain a final master to be moulded.

Flying the Rotmilan Midi

Image
Read also: Part 1: Kit overview Part 2: Assembly
After testing many many F3F sailplanes over the last 20 years, I can say that I can split them in 2 main families: the "Slippy" and the "Grippy". The Slippy includes planes having a fast natural speed, even with low ballast. The grippy are  planes providing lots of lift in the turn and that can carry lots of ballast, and most of the time need a minimum weight to fly fast. The Rotmilan is part of the Slippy family, that is to say using a section which is more naturaly fast.



In small condition, the Rotmilan is fine but cannot do tight turns with low lift. It starts to breath in medium condition and is an easy and well mannered plane. In stonger condition, it doesn't need too much ballast, and can manage the crossed wind good.  The Rotmilan is also doing excellent bank and yank turns, very aggressively, where some other place doesn't like it. Energy management turns or half roll half loop turn are also possible…

Breaking news: New DS world record at 813 km/h !!!

Image
The 800 km/h barrier has been broken by Bruce Tebo flying his Kinetic 130 at Weldon (California) the 22th of November. After a first flight at 503 mph, Bruce improved it with 505 mph (813 km/h). For information, he doesn't use any gyro in his plane.









Fresh air and some snow !

Image
This afternoon, I went to col de Faisses again despite some snow falls the previous days. The ride to the top was a bit difficult because of the snow, even with a 4 wheels drive, certainly because of the summer tires. Temperature was cool, about 8 degrees, and conditions smooth, with around 6 to 8 m/s. I was alone adn had the entire slope for me :) !


I used the mobius action cam in photo mode, and timelapse to take to onboard picture with the cam attached at the wing tip. I also did some video with the mobius and also the GoPro on the ground.


Zepsus Magnetic BEC

Life, Lipo or more recent Li Ion receiver batteries are usually in 2S so deliver high voltage. However some servos released few years ago have not been designed to support high voltage and can at least reduce their lifetime when used with high voltage, or even can burn. Zepsus, well know for the magnetic switch that became very popular all around the world and equiping lots of F3X glider, recently released a new magnetic switch that includes a voltage regulator.

This Magnetic BEC features an impressive 14A max output current, operates with a 3 volts to 10 volts input voltage, is configurable to deliver 5, 5.5 or 6V output. It is compatible with all chemistry, from a 5S NiMh or NiCd to the more and more used 2S LiPo, LiFe, LiIon. The big advantage of the Lixx chemistry is that they can deliver higher current corresponding to the very demanding modern servos. The voltage regulation is linear, so what I would call RF friendly (ultra low RF noise) at the opposite of the usual U-BEC that …

[Movie] Interstellar

Image
Seen on RCgroups:

The opening sequence of the movie INTERSTELLAR with an indian drone flying alone over the fields was done using a 33% scale Predatorish miniature, 5.5 meters wingspan, weight from 10kg, powered by  a Neu propulsion sytems. The group of south california soaring modelers composed of Larry Jolly, Ben Clerx, James Turner, Dennis Brandt, Dean McCoy, Chris Jolly, and Anya Ellis all pitched in, and helped get things done in time..

For information, Larry also participated to the movie Armagedon, and plenty of other nice project in Hollywood !

The full story can be read here

Interstellar is a super movie from Christopher Nolan, with a nice story (A group of explorers use a newly discovered wormhole to surpass the limitations on human space travel and conquer an interstellar endeavor.), excellent actors, superb visual effects. It lasts almost 3 hours, but the time passes very quickly. I really recommend it !




3D printed radio installation

Today, I could see a very nice radio installation in a Electro Alpina 4001. All the different part have been 3D printed. The servo tray use an inner honeycomb structure. the propulsion battery support can move to change the center of gravity. The orange box host the receiver and the power switch. I have no picture, but the servos covers were also 3D printed. All parts uses PLA material and are made on a printer having a volume of 20cm x 20cm by 15cm for the height. The result is very neat and clean as you can see on the pictures.


2 new color schemes for the Vagabond

2 new color schemes for the Vagabond from Hacker Model. The honeycomb is very popular now ;) !

VV Stinger

While the Stinger 2 is about to be released soon, here are pictures about the kit of the Stinger. This one is not belonging to me, but stayed at home for few days before to be delivered to his happy owner.


Col de Faisses

Some pictures taken at col de Faisses the 1st of november. My F3F planes stayed in the car and I flew only my Weasel Black Edition. Other planes were mostly powered as the conditions were very light. Still a nice and cool afternoon with a super light for pictures.


2 weeks before, I had another session there where I could meet some pilots from Lyon area. Conditions were much better.


Aerial pictures: Castle of Bon Repos

While some stupid people are flying with drones over french nuclear power plants, there are many better things to do with a quadricopter like photographying the Castle of Bon Repos near Grenoble. The Quad is aTBS discovery and the cam is the GoPro3 black edition in timelapse mode. From the 580 pictures taken, I selected only 33 to create this photo album.


Zepsus Magnetic BEC

Image
Zepsus just released a new product called "Magnetic BEC", which combines a magnetic Switch and a 5-6V linear voltage regulator. It allows to power a F3x glider equiped with Low Voltage servos from a 2S Life/Lipo/LiIon battery. It is available in 2 versions: 14A for F3x plane and 5A for HLG gliders. Given the excellent quality of Zepsus products (I have 5 Zepsus magnetic switches in my F3F planes), there is no doubt that this new Magnetic BEC will be a best seller !

Rotmilan Midi Assembly

Image
Note: you can read the first part here: kit overview
The rotmilan doesn't reserve any real surpise during the assembly. There are however some particular points to to take care so I will develop. On the fuselage, the most delicate operation is the wire routing from the front of the fuselage to the green plug print location. Because of the bassat tube already in place, there is very little remaininf space on each side to route the 4 wires. They must be under the ballast tube, then go on the side to reach the wing plug hole. Here is the technic I used. I prepared the servo wires, around 45 cm long (the standard 30cm servo wires is too short). then using a thin piano wire (0.8mm) or a thin plastic sleeve, I passed it from the joiner location to the fron of the fuselage, then taped the wire extremity to it, and pull carefully until the wire exits. You need to do it 4 times (2 on each side), given that the second wire has even less space since the firt one is in place. Doing like this,…

French F3F League

Image
Hereafter are some pictures of the 2 last contests of the french league. First of all the Vosges 2 contest beginning of October, where ae flew on Staurday in very variable an light conditions on the south west slope. Aubry Gabanon won the competition on his FS 4.3, taking a good option on the league victory. He is followed by Arnaud Leger (Pike Precision) and Elian buchholtz (Arsen).



Last contest of the french league was the week after in Laurac. After 12 rounds and an hard battle between Aubry Gabanon (FS 4.3) and myself (Shinto and Pike Precision slim), I missed the contest victory by 4 points over 1000 at the last round, and as consequence, the french league winning by 9 points (over 4000). Aubry deserved his victory as he piloted very well and did no mistake. congratulations to him ! Sébastien Lanes (Target and Stinger) is finishing in 3rd position of the contest after a very good climb the second day. JB Deguelle is 4th and Frederic Hours is 5th. A great contest, with good weathe…

Real size gliding at Saint Eynard

Last sunday afternoon, I went to the Mont Saint Eynard, above Grenoble to see real size glider doing slope soaring along the cliff. Impressive, especially the noise. Few days ago I was in the plane (Taurus), this time I was on the ground. It was mainly ASK13, but I saw also a duo discus. Nice moment !


F3F Season ended

Image
F3F season 2014 is finished for me. It has been a great season with nice results:
- Team world champion  in Donovaly (F3f WC) - 5th in individual at the same F3F worlds - 4th at the Eurotour, only 0.07 points from the podium ! - National F3F champion 2014 (7 titles) - Second of the french F3F league - New personnal best time with 28.01s (Needle 100 DSL) - 1 worldcup/Eurotour contest victory at Col de Tende
I would like to warmly thanks my sponsors MKS and JR. DMSS 2.4 is rock solid and new MKS HV servos are just incredible. The HBL 6625 is for me the best wing servo ever ! With the new HBL 6625 mini, the 6125e HV and the 6100 HV, without forgetting the 737 HV and the 747 HV, the family is now large and provide a solution to each situation.

Rotmilan Midi, kit overview

Image
This is the shorter version of the Rotmilan which just won the F3F WC 2014 in František Ruisl's hands. With a wingspan of 2.86m and length of 1.47m, it features the same HN section than the Standard Rotmilan, It is made by RTGmodel (Website not updated yet with the Rotmilan Midi). I received my Rotmilan Midi in Donovaly when I was there for the F3F world championship. The color scheme is mine and based on the constraint that the control surfaces are moulded with an angle to allow the moulding of the wipers at once.

Let's have a look to the kit. Fuselage is made from Kevlar and Carbon. It is 2.4 friendly as the front part is kevlar only. The ballast tube and the servo tray, as a single piece is already installed in the fuselage. The tray is designed to receive 12mm standard servos like the MKS 6125e or equivalent. The hole is at the right size to not damage the wire when inserting the servos in its location.

Canopy is fiber glass with the lock system already in place.

The balla…

Font D'urle 2014, the french longpan slope !

Font D'urle 2014 will remain in the memories for a long long time. The reason is that conditions were super fast and that the french F3F record has been beated several times in few minutes, by different pilots. The contest took place on a high cliff in the south vercors (french alps) with strong wind (14 to 16 m/s vertical). We have the authorization to fly there only once a year, and were are accompagnied by an eco-guard to check that vultures living there are not disturbed by the gliders.
On sunday, the wind was so strong that we had to stop the contest after two rounds, because almost all pilots damaged their plane during the landing in a huge rotor, despite walking far from the edge to escape this rotor. With 27.28 seconds, Frédéric Hours established a new french F3F record flying an Alliaj HM (in fact the early prototype of Alexis Maréchal). Jean-Luc Foucher and Allan Cohen joined the 27.xx club, both also on Alliaj HM. Personnaly, I achieve my personnal best with 28,01s with…

Icare Model show 2014

The 20 and 21th of september.

The now famous and popular Icare Model show (Coupe Icare) is since few year having also an aeromodelling show where it is possible to see all type of aeroplanes from the drone to the big aerobatic plane, etc ... Weather was not exceptionnal this year but we could however do many demonstrations from 10am  to 4pm. Less spectators because of the weather. Here is my photo album shooted on sunday

The Beaufortain, Savoie

End of september, I visited another slope paradise (Beaufortain, Savoie) not very far from Grenoble. I took only my Weasel and flew 5 minutes at le Cormet de Roselend. There are plenty of slopes in the area and some of them have the Mont blanc in background. If you add to this the fact that the beaufort cheese (http://en.wikipedia.org/wiki/Beaufort_cheese) is produced there ... yum yum ...
A very nice place to go with stunning landscapes as you can see on this photo album !

Flying over Grenoble

I had the chance to enjoy a flight but also pilot few minutes a Taurus from Pipistrel (World’s first side-by-side ultralight powered glider). We did some slope soaring on a cliff above Grenoble. A 1 hour flight in excellent conditions, ended by a smooth kiss landing at Le Versoud airfield. Thanks to Olivier Finck (http://www.airtech-rc.com/) for this flight !


Pikes Slim radio installation and maiden flight

Installation is (very) tight, but fine as after some thinking, each element finds its place naturally. Some changes however: I installed the super tiny and powefull MKS DS6100 for the elevator (note: The MKS DS6125e can fit).  I replace the 8 channels receivers by a 6 channels receiver, installed on top of the fuselage. The battery is a 2S LiIon 2900 mAh, so I have S-BEC in front of each servo. Satellite is in the nose. First antenna is below the receiver, in a plastic sleeve glued in the fuselage, the second antenna is on the side of the receiver with an angle of 45 to 60° (not 90° as idealy recommended).


At the end I needed about 130g of lead in the nose to retrieve my optimal CoG of 107mm. I will keep my current settings as the rear boom has the same length. Empty weight is 2170g for a double carbon ST wing version, which is a very good weight for F3F.
Maiden flight occured end of august, few days before my departure for the World championship on Slovakia. Conditions were light an…

Report: Alpine F3F cup, Briancon

Image
1 weeks after the FAI of col de Tende (eurotour/worldcup), most of the pilots met again in the french alps in Briançon for a contest of the Eurotour. the specificity of this contet is that we reach the slope using 4x4 cars therefore the number of participants is limited to 30. This year, I have been honored by the organisers to be responsible to drive one of the 4X4 cars. This is my first experience ever, and I really enjoyed it, with my copilot Mickael Krebs. The first day os the competition we went to the south slope, waited a bit for the breeze to install, then started some rounds. Conditions were very variables from one flight to another. At the end of the day, we had 4 rounds in the pocket. Matthieu Mervelet was in first position, followed by Frédéric Hours and Stephane Riccobono. On Saturday, we changed to the North slope located at 2400m of altitude. The wind was blowing strongly so we could expect lots of additional rounds and a change in the ranking. This slope is very tech…

Flying the Vagabond from Hacker Model

I programmed several flight modes with different amount of elevator. Normal flying with normal (but still agile) elevator, full elevator position with lots of exponentional to keep the Vagabond controlable and a thermal position with some camber and little elevator mouvement. Despite this, the Vagabond needs an adaptation time. It reminds a very agile plane, without inertia, and very neutral which needs always some attention to pilot. It is possible to fly the Vagabond in small conditions and thermals with it. Now don't expect to do long transition to catch the thermal. I you go through sink air, the plane will show it clearly and loose altitude quickly. At the opposite, I flew the Vagabond in strong and turbulent wind. The structure is flexing in all direction, but the plane remains controlable. Now this is not fun and there is no means to ballast it. No, the best conditions for the Vagabond are a gentle breeze creating a stable lift at the edge. Here everything becomes possible…

Report: FAI Col de Tende

Image
The 18th, 19th and 20th of July was the first edition of the FAI contest of the Col de Tende at the border between Italy and France. In fact this contest was formerly the contest held in Caussols, but organisers decided to move it to Tende to use this exceptional slope with good breeze conditions in summer. For this first edition, plenty different nations were represented among the 32 competitors coming from France, Germany, UK, Poland, Cezch Republic, Switzerland, Netherland, Austria.
Friday, after the briefing at the end of the morning, we could complete 2 rounds, the third one couldn't be validated because of too many reflies and also because of the wind dying
Saturday was a great day as we could fly 8 rounds. Conditions has been very stable as expected. Only the clouds appearing time to time because of the pressure and humidity had to be carefuly followed.
Sunday, we could add 4 more rounds to reach a total 14 rounds. Unfortunately, it was 1 round less than the number require…

V-Venture, le prêt à voler selon Graupner

Image
Introduction

Le V-Venture est le petit nouveau de Graupner sur le segment des moto-planeurs de début avec moteur propulsif. Il rejoint le Rookie vendu par la même société. Il vise davantage le jeune débutant pressé de voler et ne voulant pas s'embarrasser avec la construction. Il est du coup disponible uniquement en version  RTF, livrée avec un émetteur MX10 ou en version RFH qui signifie «ready for Hott» le système 2.4ghz commercialisé par Graupner. C'est cette deuxième version que je vous propose à l'essai aujourd'hui.
Présentation du kit

Le V-Venture arrive dans une large boite, bien calé dans son fond de boite en polystyrène. Ce qui attire immédiatement l'attention, c'est ce stab en V déjà assemblé, non démontable et ne fournissant que la fonction profondeur. Ce choix de conception est de prime abord curieux et prend à contre pied les modèles de débuts traditionnels «dérive-profondeur». Nous verrons lors des essais en vol si ce choix est finalement judicieux…

Planet-Soaring is back

Image
Hello  all!

After a summer break, planet-soaring is back with plenty of work on the table. I just returned from the F3F world championship in slovakia where I got a team gold medal with my team mates ! the week before, I also kept my national champion title in Ardèche on a super spot. We did 20 rounds in 2 days with plenty of fast time and a sub-30 (29.40s) for me which is not so often. Erlier in the summer I broke my personnal best in the vercors with a 28.01s. I also won the eurotour/world cup contest of the col de tende on the France/Italy border. In brief, a very sucessfull summer with plenty of nice memories, and pictures that I will share with you in the coming days !
Stay tuned !






On the road !

Image
The french national F3F team will be on the road from tomorrow until the 15th of September, starting by the national championship in Ardèche during 3 days, followed by a world cup contest then the world chammpionship in Donovaly (Slovakia). We will try to post update and pictures daily on our blog, so feel free to visit us often and let a message !


New Pike Precision Slim fuselage

Image
Samba Model is releasing a new slim fuselage for the Pike Precision. Philip Kolb, one of the designer says about this new fuselage:

"As we are always interested in areas of improvement on our planes we are especially intriegued to save drag - especially on fast flying aircraft like the Pike Precision.
Honestly it is very difficult to reduce drag on the wings' sections as the wing needs to operate within a wide variety of lift coefficients. Reducing airfoildrag at low lift coefficients and high Reynolds numbers - so to say at high speed - will almost certainly result in worse performance in other flight phases than speed.
One easy area of improvement though is to reduce the surface of the fuselage. The latest state of the art equipment (batteries, recievers and servos even became smaller than before and thereby allow to reduce the length and diameter of the fuselage nose. This reduction will mainly result in a reduction of inertia, as the nose can be shortened to some extend.
High…

Vagabond assembly

The Vagabond is ready ! It weights 620g. Overall, the assembly went well, the design for an EPP glider is pretty good. I started by the fuselage and carbon rods to stiffen the boom. Then I also installed the elevator and rudder control rod sleeves. Be careful to not bend them while installing them into the foam because when bent they can make the mouvement of the rod less smooth and bad neutral position return. The servo tray is glued on the EPP using fluid cyano. Once done, I focused of the tailplane, that I wanted absolutely to make removable. My first idea, what to modify the joiner extremity (4mm carbon rod) to lock it in rotation with a corresponding print. Problem was that I still could twist the tail because of the rod torsion. My clubmate Joel Marin, who build a Vagabond too, found a clever and simple solution for the tail: use a small aluminium tube at the root, and drill a small hole in the tube and the carbon rod to install a stop pin. The pin have a L shape to secure it w…

How to make very inexpensive 2.4 ghz antenna sleeves

I use a cotton bud (Q-tip) that I cut to keep the center part. Diameter is perfect for 2.4 Ghz antenna, even with shrink tube around. Then I put some hot glue on one side to block the antenna. In the fuselage I glue one guide with cyano. For the second antenna, I let it free but use a piece of coroplast to position it correctly (vetically), along the receiver. The cost ? 500 cotton bud cost 30 cents so cost is 0.12 cents for 2  !!!!

PS: of course, you can use the cotton bud in your ear before to cut it, so it is even cheaper !!!!!


Fully moulded, 3.5m, Fox

On sunday, I went to the col des Faisses, near corps. I met there Pierre Emery with his very nice Fox, 3.5m wingspan, fully moulded, originaly sold by Graupner, but in fact made in china by Launch Model (ex zoom model). The plane is beautiful and flies very well in addition to be georgous in the air. Hereafter are some picture I did.



Shinto maiden flight

Maiden flight of my Shinto went very very smoothly. I went to the col du glandon again because the weather forecast was indicating no wind or 5km/h maximum from west, south west. I was however expecting some thermal breeze created by the valley. when I arrived, the wind was coming from the north east valley. The time to walk to the slope, the wind stopped and switched to south valley. So, I drove 1 km, climb to the slope. The gentle breeze was about 4 to 5 m/s, not more. So I launched the Shinto unballasted and everything was perfect from the beginning: no trimming needed, CG fine, settings fine with the right amount of snapflaps, differential OK. Empty weight is 2103gr and CG is set to 86-87mm. The Shinto is very easy to fly, very precise, and manoeuverable on the ailerons. I found the flaps to work very well in thermal position and efficient in butterfly mode to slow down the plane (empty, that's right). The Shinto, as soon as it takes its speed is impressive and easy in turn, w…

Graupner V-Venture review in Modèle Magazine

Image
My 4 pages review of the V-Venture has been published in the July issue of Modèle Magazine.



Shinto assembly

Below are some pictures of the assembly of the Shinto. the LDS installation requires some attention as everytinh is very tight. The result is perfect, with no slop at all, removable servos despite they are bigger than recommended. In the fuselage I used the new HV 6125e from MKS, so the plane doesn't need any S-BEC, as I 'm powering it with a Li Ion 2S 2.9A battery. Empty flying weight is 2100gr. I didn't need any lead except the one moulded and provided by Vladimir. I also produced a spreadsheet for the ballast. I found that above 1.7kg of ballast you need to put some balance lead in the nose as the CoG is moving backward of 3mm. 


Hacker Model Vagabond: Kit Overview

After a long long wait the Vagabond finally landed, and the wait was worth it. What is the Vagabond ? It is the first widely commercial VTPR glider, made from EPP foam and printed for a nice color design. It exists in 2 versions: uncovered, and covered with a laminate film (wings, tails and fin/rudder). It features a SB96V section, nearly 90° tail rotation and weight around 500 and 600 depending of the version.

 Below is the photo album of the kit as it arrives:
Unlike other EPP plane (foam cutted), the Vagabond assembly is well advanced. Wings are nearly finished, just needing the servos, control horn and rod installation. The fuselage need some work, like insert the carbon rods for the stifness, the sleeve for the rudder and elevator control rods, the servos tray, the root section in the middle of the fuselage.

Overall degsign is well thought, except the tail plane which is not removable. This is a shame because the wings are. Now this is perfectly understandable as the easiest w…

F3F in the Vosges (route des crêtes)

Excellent competition last week-end in the east of France (Alsace). We managed 16 rounds with 21 pilots (7 rounds on Saturday, and 9 on Sunday). Saturday, conditions were light with some crossed wind, best time at 44s. The rain came around 4pm. On sunday, we had a beautiful day, with stronger wind. Top pilots were always in sub-40. I personnaly achieved a nice 32s with my Needle 115V despite a very slow last lap after the plane stopped in the last turn . But the best time of the competition went to Frederic Hours with a superb 30.40s with his Stinger. The top 4 was very closed between Aubry Gabanon, Frédéric Hours, Mark Redsell (who came from UK) and myself. Frédéric finally won the competition, followed by Aubry (992 points), I finished third (987 points) and Mark in 4th position (986 points). A veny nice and intense competition, in a beautiful area. A big thanks to the organisers Renaud and stéphane !



And below is the usual short video from Aubry Gabanon, giving a different perspect…

[Essai en Francais] Libelle de Dream-Flight, le lancé-main pour tous !

Introduction

Suite à l'incroyable succès planétaire de la Weasel et de l'Alula, suivi coup sur coup de l'arrêt de leur production pour diverses raisons, tout le monde attendait avec impatience et fébrilité ce que pouvait nous réserver Dream Flight pour prendre la relève, quand début février son patron Michael Richter annonçait la sortie de son nouveau modèle et une première, un lancé-main moulé en elapor ! Alors que les prix des lancés-main tout composite atteignent des sommets en raison de leur construction toujours plus high-tech, le Libelle se positionne lui comme modèle de découverte de la catégorie, à moindre coût. Pari gagné ?… C'est ce que nous allons voir dans cet essai.

Un kit dans la pure tradition Dream Flight

Ce qui m'avait frappé lors de l'essai de la Weasel et l'Alula, c'est une conception particulièrement aboutie du modèle, dans ces moindres détails. On retrouve ce souci du travail bien fait avec le kit du Libelle. A l’ouverture du joli ca…
