Video: An afternoon in Corps

Here is the video I did last saturday in Corps. The news is that I tried to film with my EOS 650D in addition of the onboard Keycam 808#16 V2 Lens D. I'm satisfied with the result. Therefore in order to ease the video shooting, I invested in a LCD viewfinder to allow better viewing while filming. I also need to work on the settings in video more to obtain a more consistent result.

Video: A terrifying launch !!!

The following video from Franz Dschulnigg shows a terrifying launch of a 7m Arcus from the top of a cliff in Switzerland. This is just scaring, even if everything goes well. Unfortunaltely the video doesn't include the landing that must be also challenging considering the topography of the place.

The July issue of RC Soaring Digest has been released. It includes an interesting study about dimpled wing aerodynamics and some reports about thermal duration event and also semi scale towing meeting in UK. You can download the issue using this direct link: HERE

An afternoon in Corps

Image
Saturday was a slope club meeting in corps. Not really a sucess in term of participation as we were only 5 pilots of the club over around 60 members ! but a very friendly and successful flying afternoon and a superb slope despite the light conditions. The sky cleared progressively at the beginning of the afternoon so we could declare the thermal hunting open ! Arnaud from Gap and Sylvain from Lorraine as a special guess joined the group. Lots of F3x planes, which was the good choice for this type of condition, but also the ASW15 of Joel. We finsihed late, once the wind died with the sunset. 
On my side, I flew my Schwing 88 and my Pike precision, both without any ballast. I damaged my Swching after going very very low and trying to do an emergency landing 3 or 400m below. I stalled at 5 meters of the ground and broke the fuselage in front of the wings. I'm nicely surprised to see how the Schwing resisted to the crash given the heavy impact. The thick servo tray, solidly fixed wit…

Pike Precision Electro, new layout

You have probably noticed that since I presented some pictures of the Pike electro fuselage, I didn't show more, and post a build log. The reason is that I spent lot of time to arrange the different element in order to place everything to keep the CG fine, make the installation possible, and especially the maintenance.  The conclusion has been that the fuselage is so thin, that this is nearly impossible. For example, on the elevator servos installed with the servo tray provided, it is then impossible to remove them. This is at the point that some owners decided to not glue the front part of the fuselage in case they need to access the servos.
So I continued to think about a possible layout and concluded that I needed to save more space in the middle of the fuselage, so remove the servos tray, and locate the elevator servos somewhere else. I finally ordered a new set of tails that I should receive in the coming days. The idea is to install the servos in the tails (MKS…

2014 French F3F National Team Selection

Image
F3F french National team for 2014 (World championship in Donovaly) is in progress and consists in taking the best 3 results over 4 contests among

    The Pyrenees Cup    2 dedicated selection contests    The french champioship (end of august)
Results of each contest are ponderated by the number of rounds flown. This make the calculation much more tricky because we need to calculate for each pilot all the possible combination to identify the worse result contribution to exclude from the final ranking. Selection contest cannot go above 15 rounds in order to limit their weight against other normal contest with more pilots so less rounds. I know this is a bit complex, but the idea is to be fair.
Anyway, last week end was the first selection contest following the team 2013 training. For weather and autorization reasons, this constest took place in the south alps near Aspres sur Buech. 8 pilots took part to this contest.  We have been able to fly 12 rounds the first day. We got lots of cross…

F3F national team practice

Image
Last thursday and friday, I met with the french national F3F team 2013 for a practice and team building session as it was close to my home place. On Thursday, we went to the north slope of Corps but unfortenately were unable to fly as the wind was absent. For friday, we decided to go to Aspres sur Buech in the south alps, with the hope to get more wind and less thurnderstorms which was almost the case. We got some wind, a bit crossed but still OK, and later in the afternoon we could see some showers here and there around our mountain. The 3 pilots have been able to practice, with the course setted up despite the flying condition were not great... The next session will be end of July near Briançon for a day, preceding the league contest at the same place. Here are some pictures taken these 2 days:

Take Of Ardechois 2013

Image
Weather continues to disturb the beginning of the F3F season in France. After the snow the previous week, this time was the strong wind. Ardéche is like the south Alps, plenty of nice F3F spot and windy place. Up to now, this competition was missing a good spot for north wind. Yves and I combined our effort to identify a new spot. I worked on google earth and geoportail (detailed maps) to identify a new slope. Yves visited them to validate the spot the week before the contest. Like this, we found a new promising slope, with very little walk. This where all the competitors went on Saturday 1st of June. Problem was the wind reaching 25m/s during gusts, even is the average was within the FAI limits. But this strong wind was creating huge rotors above the landing field. After a long wait, we decided to start the competition, doing 2 rounds in the same flight with a crow start in order to save one landing. We managed like this 2 rounds with very fast time, fatest time around 31s, and almo…
