Video: Schwing 88 at the Pierre Percée

Image
The "Pierre Percée" is a natural stone arch located on a hill upon the commune of Pierre-Châtel and La Motte d'aveillans, 30 km south of Grenoble. The slope faces the south direction and offer a stunning and awasome scenery with a large valley, which is in fact a plateau surroundered by mountains. On this plateau (also called Matheysine) , shaped by glaciers during the previous glacial periods and surrounded by high mountain ranges, the bise wind blows intensely, being frosty during Winter, but pleasant in Summer. Furthermore, at Winter time, the area can face heavy snowfalls. For these reasons, Matheysine is being nicknamed "Little Siberia".

All this area and the mountains around are my playground with plenty of slopes I fly in summer. I must agree that I live in a beautiful place. This is one of the reason I moved here to finish my studies in 1987.
I haven't flown this particular slope for almost 20 years so it was like a new discovery today. The slope p…

Video: Grenoble from above

Image
In this end of the year (not of the earth hopefully ;) ), today was sunny enough to do a short aerial video with my EasyStar 2, equiped with the GoPro and the Keycam 808#16 V2 Lens D.
This is the version RR of the Easystar 2, and with the 200g of the 2 video cam, the plane was obviously underpowered. I need a better solution for aerial pictures and video. I also noticed some jello effect this time, so not enough filtering of the vibration.


According to Wikipedia, Grenoble is a city in southeastern France, at the foot of the French Alps  Located in the Rhône-Alpes region, Grenoble is the capital of the department of Isère. The proximity of the mountains, as well as its status as the most populated city of the Alpine region before Innsbruck and Bolzano, has led to the city being known in France as the "Capital of the Alps".
Grenoble's history goes back more than 2,000 years, at a time when it was a small Gallic village. While it gained in stature by becoming the capital o…

Keycam 808#16 V2 + Lens D

Image
Few year ago, I had a keycam and lost it during the first flight. It detached from it support and falled from altitude on the slope. I never retrieved it. At that time the resolution was VGA, the image format 4/3 and the FOV was too narrow.
Things has changed over the years and we can easily find HD ready and Full HD Keycam. the most interesting things is that now you can find it with a new lens D that provide a FOV of 120°.
I really wanted a cam to mount almost everywhere on a plane, the Go Pro or equivalent cam being too heavy and big for this excercice.

I decided to give a try and bough my Keycam on EBAY. The seller is very serious. I paid via Paypal and the cam has been shipped the next day. I received the user manual in a mail. 10 days later the cam, very well packed, was in my mailbox !



I paid 53$ for the cam and a 8Go Kingston microSD card. The cam comes with some accessories: One USB cable, a pair of adhesiveVelcro, and a pair of Video Output cable (see photo). This video outp…

A nice micro slope glider: BOAR

Image
Boar is a micro slope model, just below 1 m wingspan, weighting about 320g, fully moulded, and made by the KERR soaring team in Hungary. This team is Endre Kaposi and Róbert Remény. They fly slope and F5J and obtained good result (second place at the national F5J champioship) with the F5J400OR. The created their workshop and use CNC to mill moulds, and cut parts. In project, a 2 meters V-tail sport model, called Unicorn.

Electro Schwing

Image
I read on Sloperacer's blog that an electro version of the Schwing is approaching. The design of the fuselage shows that the front part of the fuselage is removable and contains the motor, the ESC and the batteries. This layout is pretty interresting from my point of view because it give a good access to the different component. You can find more information here



An afternoon at a new slope

Autumn, while the season is off, is a good time to relax a bit, find and test new slope. This is what I did last saturday, taking the opportunity that the weather what not too bad, with good south wind. This slope is located at mid heigh of a well known slope near my home place. With what variable but on the slope. Landing has been a bit problematic with some rare stones here and there, some bushes also. But access is easy, and the lift is good. Here is a video I filmed there, flyin my Needle 100 and Schwing 88.

Video: X-Games Pylons

Here is the video I edited yesterday evening. Enjoy !

X-Games Pylons from Opale Paramodels

Image
I'm currently reviewing the X-Games Pylons from Opale Paramodels. Inspired from the famous Red Bull Air Race's one, they are inflatable pylons, made of Ripstop nylon (white part) and heavy nylon for lowers parts, and include a 120-140mm diameter fan.

What is nice with these Pylons is that they can be installed extremely quickly, and a simple 3S Lipo battery 4A can last about an entire afternoon.

We already used them with sucess at the coupe Icare during the aeromdelling show. Yesterday afternoon, with my clubmate Joël, we installed them in a field to do some pictures and especailly video sequences. It should give an interresting and nice video clip, stay tuned !

Coupe Icare

The Coupe Icare is the world’s biggest paragliding and air sports event, bringing together pilots, manufacturers and free flight professionals of all sorts, passionate amateurs and curious onlookers for the most fun, flying festive event imaginable. http://www.coupe-icare.org/



I participated for the second time to the aeromodelling air show, letting my F3x at home and flying instead foamies. We organised pylon racing demo with Merlins (MPX), and Kinetics (HK). We have been using X-games pylons made from ripstop nylon and heavy nylon for lowers parts. This is really a great accessory, installed in less than a minute, looking really great.

This year we also built special model to do the show: 4 Skymans (Ironman, Spiderman, GreenlLantern, and Batman). They had lots of sucess with childrens.


My clubmates did also some patrol flights with 2 Corsairs and 3 P38 Lightnings. This event is huge, extremely well organised and showing many different activities going from aeromodels to hot ballo…

Flying the Schwing

I maidened my Schwing 88 the previous week-end, and I have been able to do nice shots to share with you all.

The Schwing is very good in the air. Nice looking, agile, light, on rails.
I started with the recommended CG at 99mm the first day, but found it was too backward because the plane was too sensitive to the camber variation. After adding 10 to 15gr of lead, I'm probably between 97 and 98mm now.

I flew around 2 hours with it the day after. The schwing is excellent in academic aerobatic because it tracks very well. Vertical manoeuvers are large and nice, you can control it at any time to apply the necessary corrections.

But its agility allows also to fly low and close. The roll rate is just great ! You don't need to prepare to start the roll, you just do it as you feel it.

The stalled rolled is also impressive, but requires some height because the plane needs 2 to 3 rotations before to get some grip again and exit safely.

In my setup, I used snap flaps DOWN, but also UP to …

Schwing 88 Assembly Log # 2

Last time I let the Schwing very close to the completion. First of all, I glued the green MPX connectors in place. I usually do it with the wing mounted, so I need some release agent here and there. Once the servos connected to the harmness, I used Samba transparent servo covers to close the servos bays.



Then I completed the installation of the elevator and rudder control rod, using MPjet M2 coupler. I needed to use a ball clevise for the elevator because of the shape of the DS6100 servo. I spent some time on the balance because I made a mistake with the servos tray installation. It is installed too forward which reduce the space for the lead to achieve the right CG. In front of my 1500mAh NiMh battery, I have been able to put only 70gr of lead., then about 50g on top of the battery. As I didn't have remaining space for more lead, I ended byt putting the rest of the lead in front of the canopy. I have a total of 190gr of lead to get the right CG at 99mm, as recommende…

Schwing 88: Assembly log #1

I started few days ago the assembly of the Schwing 88 from sloperacer.co.ukOverall, everything went well for the moment. No surprise, only smooth step by step building.

The fuselage:

The main work consists in gluing the ballast tueb and the servo tray in the fuselage. Before this operation, I prepared the ballast tube. I used some  3mm plywood as tube end stopper. After cutting it at the approximative diameter, I made a hole in the center, then fixed it on my mini-drill and sanded it to obtain a perfectly round piece, at the exact diameter. I glued it in place with some expoxy, then installed a 2mm carbon rod in front of the stopper, piercing the tube side to side.A small piece of hard foam is inserted in the tube to act as a shock absorber.

After opening the front of the tube to allow the ballast slug to enter/exit, I installed a small wood block with a screw nut inside. The wood block is rounded a bit to go in the bottom of the fusleage. The ballast tube is glued in the fuselage u…

Col du Glandon F3F

Image
The 2012 edition of  Le col du Glandon F3F constest has been a bit challenging this year. When we arrived at the car park temperature was 2° celcius, and we spent saturday on the parking to wait for the sky to clear, but this never happened. We left around 4pm with 4° ...

Sunday, hopefully the sky cleared during the night and we arrived around 10am with already 11°, but also a superb scenery with the Mont Blanc summit in front of us.
Small problem is that the wind was east when the valley is north-east, the brezze was time to time jumping between valleys and was crossed on the slope.

We however managed 3 rounds with lots of interruptions, with 16 pilots. In this particular conditions, the slope didn't keep its words and was evetyhing but consistent with very short cycles, interruption, restart, 25 minutes interruption, then resume, etc ...

At this game some pilots were well served, and Thomas Faure did an hold up on the 3 rounds, winning by a very good margin as the second pilot …

Ballasting a F3X sailplane

Image
It is always a problem to know exactly how to ballast a F3X plane given that they are several ballast compartiments with different size/volume, and none of them is exactly at the center of Gravity. I created the following spreasheet to help you how to determine the ballast, and also calculate the CoG variation.

How to use this spreadsheet?

Enter in the yellow cells:
The position of the CoGThe position of the different ballast compartiment (measured at the center of the compartiment)The weight of the ballast slugs for each compartimentThe empty weight of the plane As ouput, it will give you:
The total ballast weightThe flying weightThe wing loadingIt will highlight in red when exceeding the FAI wing loading of 75gr/dm2More importantly, it gives the variation of the CoG.
Feel free to report mistakes, bugs if you find some. Thank you.

Schwing 88 kit overview

Image
The Schwing 88 is the first allround slope model born from the partnership between James Hammond (the father of the Strega, Typhoon, Vector, Minivec, and some others ...) and Tony Fu from SlopeRacer.co.uk.

The Schwing 88 is a very nice looking 2.23m wingspan slope plane which includes improvement from previous JH designs, based on feedbacks and learning experience. It features new combination of airfoils, semi eliptical lift distribution, large control surfaces. The fuselage is slim and with a canopy, but still host a massive ballast tube and the servo tray for 2 servos, the receiver and the battery.

The plane is distributed worldwide by SlopeRacer.co.uk or by its distributors in some countries (i.e SoaringUSA). I received one exemplar of the first production batch.

So, what do you get ?

The wings are fiberglass. The finish is clean and the level of completion is high, as expoxy wipers are done, brass control horns are installed, and a carbon reenforcement is in place in the servo ba…

Practice session at Le Col du Glandon

This place is where french F3F was born in 1994. With the coming yearly french league context next week, I drove there to meet with 2 F3F mates and enjoy the north slope. This is the first time this year that I go there, but I should really go more often as the north slope is really appropriated for F3F with its sharp edge. But the main characteristic of this slope is the fact that the breeze is very laminar and consistent, with no or very few thermal influence. Even if the time achieved are not impressive, the flying experience is absolutely excellent, and you can do 200 laps with the same regularity, you can work on the trajectory, the turns, the ballasts, etc ... Wind was blowing around 6 to 7m/s. I started the afternoon empty to finish with 390g of ballast. 
It has been also the opportunity to try my brand new and shiny Canon EOS 650D, a important but necessary investment to continue to propose you premium photography on Planet-Soaring.
Here are the very first shots taken yesterd…

Font d'Urle video clip

I just finished the video clip about Font D'urle F3F contest. Hope you will like it. I has been film with the GoPro on a 3m boom and my Lumix FZ100. No animals were harmed during the filming, but some sailplanes did (at the landing) ! Enjoy !

JR Propo XG8 / XG11 field charging solution

The XG8 and XG 11, powered by a 2S 1400 mAh LiFe battery, have the particularity to integrate the battery charger into the transmitter case. They need a 220VAC / 9VDC adapter, provided with the radio. This solution works great at home but the downside is when you want to recharge your transmitter on the field/slope, and that you don't have 220V source available.

I found a smart solution to recharge my transmitters on the field. I bought a CCBEC from castle creation, which is programmable using the USB link to purchase separately, and which is the only UBEC to be able to go up to 9V, at the opposite of all other BEC which deliver 5 or 6V, not more.

I prepared some cable to use with the CC-BEC, on one side to connect to the transmitter plug, on the other side to connect to a 3S Lipo battery, or to connect to a 12V power source. I will also prepare soon a cigar lighter plug.

This charging solution is very convenient, in addition to be an excellent backup solution. It's light, ca…

Font D'urle 2012

Image
This competition is a special event in the french F3F calendar because the organisers have an authorization to fly there and because this is forbidden the rest of the year, being in a very restricted/protected zone. This difficult access make it a sort of pilgrimage for all the french F3F pilots, but also for our friend from Switzerland like Reto and Christian. This year has been an excellent year, in term of participation with almost 30 pilots, but also because of the weather and 2 days of south wind.

On saturday, the wind was not very strong but in round one, but Sebastien Lanes did a 34s that remained the fatest time of the day. We ended with 5 rounds in the pocket, and also with some planes damaged during landing as some pilots experimented time to time rotors during the approach. At the end of the day, Alain Galinet from Briancon was leading, followed by Sebastien Lanes and Matthieu Mervelet in 3rd.

On sunday, we started earlier as the wind was already blowing. Conditions grew u…

Alliaj HM Slim

Aeromod release a new fuselage for the famous Alliaj HM. The new fuselage follow the current F3X trend, so is slim, with the servo tray inverted, with a big ballast tube in the fuselage. This week-end, Jean Luc Foucher used the new Alliaj HM during the competition of Font D'urle. A good opporunity to have a look to it and take some pictures and video. The new Slim fuselage, event it is difficult to say that it improves perfomances, clearly gives a totally new look and elegance in flight as ou can judge on the video below.


Hints and Tips: using a heater cable for fuselage repair

Image
During the FAI contest of Briançon, I learned a great way to repair quickly and solidely a fuselage boom. The idea consists in using a ground heater cable that guarantees a regular and even heating.


This heating cable is usually used in aquariums, as well as in terrariums. I bought mine in a Botanic shop. 3 models exists: 25, 50 and 100W. For our purpose, the 25W is the one to choose, as it is already 4.30 m long.

One you have done the repair with carbon/glass cloth or tape, you first surround with some large tape or thin plastic sheet, then you roll up the heater cable around the boom and plug it to the 220v. According to the people using it, it provides a temperature around 30 to 40°.

You can also use a sheet of aluminium around the boom before to roll up the heater cable. This will help to propagate the heat all around.

After the night, the fuselage is ready for sanding and painting (if you have time) or flying if you are on a hurry :)

Col de Menée

This afternoon, I went to a super F3F spot that has been discovered 2 years ago and that we used during one day of contest of the french league. The only problem of this slope is that it is difficult to reach: 40 minutes of walk, and about 300 meters of altitude to climb, so you need to not take too much planes or equipement to stay light. I took only one Pike, my compact camera, the Go Pro, but also the 2 kg of ballast ...
The slope is very deep, and "capture" the wind very well. Because it is facing north, it is not too much influenced by thermals. Time to time you fly a bit faster, but the difference is not huge.

I was alone on the slope all the afternoon, so flew 2 hours non stop with 700g of ballast. The lift has been consistent during all the time, really a super spot !

Here is a short video I did.


T9 Hobby Sport Magnetic switch

Magnetic switches become very popular in the F3X world because they are very convenient to use in slim fuselages and because they are finally safe as they are passing if faulty during operation.
After testing 3 other magnetic switches, I received this new one from T9 Hobby Sport for review. It is now installed in my Willow F3F and worked flawlessly until its installation.

This T9 hobby sport Hall effect magnetic switch is a nice piece of hardware, with double side board and lots of surface mounted components. It differs from the competiton by proposing 2 things:

1/ A battery charge lead: This is very convenient because now you dont need to unplug the switch when charging. You can really locate the switch in a unreachable place. The charge lead is directly connected to the battery wire so in theory, there is no limitation in term of current or delta peak détection.

2/ A temporisation when switching off: To switch on, just present the magnet over the circuit and the effect is immediate…

New pictures of the French Alpine Cup (Briançon)

Joël Marin, one of the 2 CDs at Briançon for the French Alpine Cup took some pictures during the contest. Here is the photo album. The idea of Joël was to have at least a picture of each competitor. Hope he doesn't forget somebody :)

Discovering a new slope

Image
Well, to be exact, this is a new slope for me, but this slope is well known by the local fliers for ages. With my F3F mate Serge Delarbre, we met Arnaud Vincent to visit and try this slope (Puy de Manse) located near Gap.

You cannot miss it as this mountain can been seen from very far on the road when you approach the city of Gap. The site faces a large valley and take benefit of the venturi effect created by the mountains. the scenery is absolutely amazing, with the "Massif des écrins" on the north, with its national park, high summits, sky resorts, etc ...

The walk to access the slope is a bit hard, and so during 25 minutes, but the reward is real. The slope is very suitable for F3F with a sharp edge, and deep slope. The landing area is not large, but easy, and rotor free.

We spent the afternoon practising F3F, changing ballast, CoG, turn style. The flying space is really huge.
Here is a short video I did during this session. For sure, I will return there !


1st Qualifier for 2013 F3F French Team

Image
Last week-end was the first qualilfication contest for the team who will represent France in Slovakia for the European championship. The french qualification is based on the National championship (May 26 to 28th 2012), the FAI of Briançon (July 21 to 22th 2012). A second qualifier will be organised mid september. The 3 best results (with ponderation based on the number of rounds in each contest) for each pilot are kept to determine the ranking.


This 1st qualifier was on a new F3F spot, at the border between Italy and France, north to Monaco. We booked the Saturday and Sunday, just in case, but the objective was to finish on Saturday. We met around midday, and at the briefing, we decided to have 15 rounds maximum, in order to better balance the final results.

We managed the 15 rounds in 4 hours, with 8 pilots. This was possible only because of generous people who did the base judges and CDs during the whole afternoon. A huge "thank you" to them !

The slope was very homogeneo…

Eurotour F3F: 1st French Alpine Cup in Briançon

Image
This week-end was the very first edition of the French Alpine Cup in Briançon, in the heart of the Alps, close to the Italian border. Briançon is well known because it is the highest city in Europe, and Briançon claims to be the sunniest place in France with 300 days of sun per year ( A day is declared as sunny when there is more than 2 hours of sun during the day). Briancon is a very lovely city with its old fortified city. You can find more information on Wikipedia.

Following Caussols the week before, The French Alpine Cup was also over 3 days, and welcomed lots of foreign pilots taking benefit of 2 Eurotour contests in 10 days. Countries represented were UK, Czech Rep., Netherlands, Denmark, Switzerland, Italy, and France.

Saturday was initially the most promising day, with south breeze, but finally was a bit disapointing. After meeting at the car park, we continued the drive with 5 x  4*4 Pick-Up to transport the 28 competitors + organiseres and all the planes et equipment. After…

Caussols FAI / Eurotour F3F

Image
In 2012, the 2 french FAI/Eurotour contests are over 2 following week-end to allow foreign pilots to travel once and attend twice, with some tourism between. LAst week-end was the FAI in Caussols on the cote d'azur near Cannes/Nices. 34 pilots were present from several countries during the 3 days of contest (Czech Rep., Netherlands, Denmark, Switzerland, Austria, Italy, France).

Saturday, we went to the west slope. After a short breifing, we started the round 1 that stops before the end with the wind starting to blow from the left. we cancelled the round, moved to the main slope but quickly understand that the sea breeze will not win over the strong west wind, so we moved back to the west slope. This slope is in fact a south west slope, but the west wind is redirected by the valley, so it is possible to fly.





After doing round 1, we immediatly started the round 2 with some reflights because of marginal conditions. During round 3 we had some interruptions but never more that 20 minu…

Update: XG8 to XG11 memory transfer

Image
After reading some posts on RCgroups, I discovered that it is possible to copy memory models from the XG8 to the XG11 by using the SD card. I did the exercice and can confirm that it works great. See the screen below just after the completion of the copy from the XG8 SD Card to an internal memory of the XG11. This is certainly due to the structure of the menu which is very similar and also a proper syntax into the model memory file. Apparently this is also possible from the small sister XG6 to the XG11. Well done !

JR Propo XG11 overview

Image
The newest XG11 from JR Propo is the current top end of the DMSS XG radio product range. This is a 11 channels radio with 30-aircraft model memories, powered by a LiFe batteries and a SD card slot to extend memory capacity or for firmware upgrade. It comes with dedicated sailplane functions.

In the box The XG11 comes bundled either with the 11 channels RG1131B receiver or the 8 Channels RG831B. It exist in 2 versions: One with a throttle analog trim, the other one with digital throttle trim. I have the digital trim version. You will also find the AC/DC adapter to connect to the radio for charging, as the transmitter use LiFe batteries, and includes the charger built in, like the XG8.

The transmitter case First of all, the look influenced by the transformer movie is modern and great, and the bronze color finish is very new and unusual, and its red color anodized sticks too. Very Nice looking. I really appreciate the XG8 for its shape and the ergonomics, so I was a bit worried …

They are here !

I mean, F3F French Team T-shirts arrived and will reach their owners and new home very soon ! 

RDH and external bearing kit installation

I finished the installation of the RDH and external bearing kit from Sloperacer in the wings of the first Pike. I'm pretty satisfied because I obtained the deflection I wanted, and a very tight command, with absolutely no slop. As you can see on the pictures, I used the MKS wood servos frames as I'm very happy with them and the screws provided with the servos. The external bearing is maintained by a wood frame, in order to increase the gluing surface. I decided to fix the bearing only on one skin, for maintenance reasons. Time will tell if it was a mistake or not. Each part is removable, but need some method and sometimes is a bit challenging. What is really nice is that you can ajust the pushrod length very precisely. I filmed the following short video to show the RDH and external bearing kit in action, once installed in the wing.

Weekly practice at Col de Faïsses

South wind was lower that expected at Col de Faisses for the weekly F3F practice session (with Joël). We have been however able to fly well, with up do 670g of tungsten ballast. This was the first time I was using them.The afternoon was a bit disturbed by the precense of tons of horse flies, because of the cows staying there all summer. they were absolutely huge and aggressive. Standing in the wind was fine to keep them away. Here are the pictures taken by my clubmate Joël.
