Android App: Timer F3F

Image
Thibaud Ringenbach, a french F3F pilot, developped a small but great application running on Android providing a F3F stopwatch and more. You can enter the pilot names, or import it via a txt file. Then you can record the times associated to each pilot. It is possible to enter the time manually and overwrite the time recorded by the application. You can also export an output file with times and penalties.


Other improvements and feature are in progress.
From now, this application is downloadable on the Android Market. it's free, it's Opensource, it's great !!! except if you have an IPhone :) !!!

Onboard Video: Welcome to my slope paradise !

An onboard video taken with my Dingo, during the summer 2010, above the best slope of the french Alps, near Corps (Isère - France). On this slope you can do everything: combat, F3F, aerobatics, large scale sailplane, cross, VTPR, etc ...

Stratair Hurricane pictures

At La Muela, aside the competition, Stephan BERTSCHI flew his Hurricane, the day before the competition. Here are some pictures of this nice but quite expensive plane, designed by the Logo Team, and produced by Stratair in Austria.



XX powered by eneloop: AA format, low discharge and 2500 mAh !

Image
Sanyo just released a new Eneloop low-self-discharge battery called "XX powered by eneloop AA", providing more power with 2500 mAh.

More information on Sanyo Website: here

I use Eneloop batteries for few years now and I'm quite happy with them. Going to 2500 mAh will give even more flying time !


Price is about 19 Euros for 4 cells, compared to the 15 Euros for the standard 2000 mAh we already know.

Willow F3F: an affordable sport and competition plane

Image
Ian Mason contacted me few days ago to give me some news about the project he worked on the past few monthes. The result is a new F3F plane, called Willow F3F, with the objective to make mouldies more accessible to everyone. The standard (Carbon D box) version would be priced at between 500£ and 600£.
Few characteristics are the following:

Span 2.75mSection (DF01)Ballast 1.2KG2.4Ghz Friendly

Video: La Muela 2011 Fatest Time

Here is a video of the fastest time during La Muela 2011, done at round 4: Alexis Maréchal on Alliaj HM. The time is 41.06 if I remember correctly.



La Muela F3F 2011 Eurotour

I'm just coming back from a week in Spain, with some tourism in Valencia (very nice city), and ended by the F3F open of La Muela. Despite we were end of April, expecting good temperature and sunshine, weather forecasts were not encouraging at all, since a depression was centered on Madrid, with rain and low wind and temperatures as concequences.
Friday, after few rain showers, we have been able to complete 5 rounds in very changing conditions, especially in round 3 and 5, interrupted in the middle by rain, before to restart after a 20 minutes break. I payed cash these 2 interruptions as I was the next pilot to fly, and each time got very little wind compared to the first half. At round five, I was even ready to start under few rain drops but the CD decided to stop at that moment, too bad for me !
This cuts the pilots in 2 groups: the one who flew before the rain with time between 41 to 50s, and the second group flying after the rain with time between 55 to 75s. You can easily ima…

First F3F contest of the french league

Last week end was the first contest of the F3F french league. No wind on staturday, so Alexis organized some activities with a duration/speed/precision landing informal contest.
On Sunday the the conditions were very good with 10 to 14m/s of wind. We managed to fly 7 rounds with 30 pilots. I got the best time of the day with 37.53s and won the contest. I flew the first round with my Alliaj HM, then switched to the Vampire F3F to be more familiar with it as I had less than 2 hours of flight on it. I reduced the elevator a little bit as advised by Thierry Platon. Overall, I satisfied with it even I need more tuning on it.

DSing the Vampire F3F

Here is another video, taken the same day than the video about the Ambrosia.
I stopped quickly after few laps to not go too fast and break the plane 2 days before the first F3F competition of the french league.




Stop News: First F3F World Championship in 2012

The CIAM voted the first F3F WC to be in 2012 and accepted the candidature of Germany to organize them in October 2012 at cape Arkona (Rügen).

This is a good news for F3F which is finally recognized as a real category.

Team Selection in each country can start :) !

DSing the Ambrosia F3X

Yesterday, I flew my Ambrosia F3X on the darkside of the slope. It flew very well, but I couldn't accelerate too much to not damage it 3 days before the beginning of the season. Here is a very short video of it. Stable, fast, precise, we retrieve the quality of the plane. I flew it with 600g of ballast.



D-60 Maiden Flight

1.7 kg for 1.52m wingspan. This is unusual, but this is the flying weight of my D60. Yesterday, I maidened the D60 with 20 to 30 km/h of wind at my home slope. After the launch, I have been first surprised by the lift of the plane despite its high wingload. Then the cruise speed is already quite important. This is a good frontside sailplane for heavy conditions. But its home is back side :)

After few laps backside (or darkside ;) ), I had just one word to summarize the D60: woowwww !


Here is a short video of the first flights:

Flying session with the Vampire F3F

Today, I went to the col des limouches. Conditions were perfect for the flight, but too much for a safe an peaceful landing. I flew the vampire for 1 hour before to start to land. the landing zone is very small, and near the edge. This is the only place to land on this slope, because behind the eadge of the cliff, this is a suicide. I finally managed a good landing without any damage.
Here is the video of the flying session. 30 Km/h of wind. 900g of ballast in the plane.






The Vampire confirmed to be a fast plane with plenty of grip in the turn. I think again that the ballast strategy is very important with this plane to obtain the best compromise between straight speed and tight turns. The plane seems to not like to be overballasted.

my first print in a non-RC related magazine

Image
Yesterday I received a copy of a village bulletin of Jarrie near Grenoble which published one of my aerial pictures of the castle located in the village.



This is the my first print in a non-RC related magazine :)
Pictures were taken with my Easyglider equiped with a GoPro HD.
Few other pictures should be used in next bulletins.

"Open Air": a nice video clip about F3J

Image
A nice video clip from Lopi about one of the first F3J contest of the season. Lots of slow motion sequences, plenty of nice gliders:



Midday flying session with the Radian Pro

Image
Weather is absolutely beautiful at the moment in the French Alps. 24° at midday, going up to 27° in the afternoon, no wind to a very little thermal breeze. It was the perfect conditions for a Radian Pro flying session.


Thermals were popping everywhere, allowing fast climb without motors. I used only 1/3rd of the battery to achieve 30 minutes of flight.


The Radian Pro demonstrated again its great thermal capabilities, circling, transiting easily, etc ...

In conclusion, a good flying session !

Some additional Samba Model F3B/F information

Image
Lots of people though that this scoop was a April fool. This is not ! This project is in the pipe for more than 1 year.

I got few more information regarding this new plane. Design is from Johannes Dillinger, Philip Kolb and Benjamin Rodax.

The wing uses 8 different sections PB571 - PB578



I will continue to give you more information as soon as I get them.

Stay tuned !

BatGlider maiden

I maidened my Vampire on Saturday at Montchenu near Romans sur Isère, then had a second flying session on the local slope on Sunday.

The CG is at 91 mm which corresponds to the front of the wing ballast compartiment. This position seems very good. the plane has no bad habits and is quite fast.





So what to say on the Vampire ? I would say that it is comparable to an Alliaj HM but lighter. You can achieve very good speed empty. The grip in the turn is amazing and the speed at the exit of the turn is absolutely excellent.

I found that the Vampire is more sensitive to the ballast than the Alliaj HM. If you ballast too much (1 or 2 brass bars more, which correspond to 150 to 300 gr) you immediatly feel it in flight.

Overall, I would say that the Vampire is a good complement of the Alliaj HM for small to medium conditions, but need more attention on the ballast strategy.

Anyway, I need more airtime on it in the coming days ...
