Discovering a new slope

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

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…

Caussols FAI video

Martin Ulrich (His blog) posted this nice video that captures well what was the Caussols FAI. Enjoy !

French Alpine Cup photo album

Tomáš Winkler sent me the link to his photo album on Picasa. This nice album make you really feel the particularities of the contest: high mountain, difficult access, challenging landing zone, superb landscape.
Nicely done Tomáš !

Eurotour F3F: 1st French Alpine Cup in Briançon

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

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

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

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.

RDH and Fu-Fix External Bearing Kits (Sloperacer)

I discovered the RDH system concept with the Rotmilan, which is designed especailly to use it in the sense the pushrod are made from carbon, at the exact length, ailerons and flaps include factory installed the removable axis to connect the control rod to. And of course the Rotmilan came with the very special servos arms, milled in aluminium.
All this is already a big improvement over standard linkages but what was missing is the possibility to ajust the length of the llinkage, and also be able to use it with standard clevises on the ailerons side.

Sloperacer improved the system by proposing RDH adapters made from brass to use the RDH arm with conventional pushrod, 2mm Stainless steel 303 grade pushrods of different length. Used in combination with standard M2 clevises and metal horns, it is now easy to install RDH easily everywhere.

On top of that Sloperacer proposes also to enhance the servos installation by mounting Fu-Fix External Bearing Kit, in order to maintain tightly the servo…

Second training session of the french F3F team

End of April, beginning of may, the French F3F team met again at Oleron island on the west coast of France after a long drive to practice F3F on similar slopes that tha one we will possibly fly in Rügen. 2 entire days of intensive flying in strong conditions the first day and very light the second day. Very useful and instructive for the pilot ! Here is a short video clip:

Col de Faïsses

I drove to the Col de Faisses again yesterday where I met several clubmates there. The wind was blowing at 75 km/h average, with some dust at 95km/h. I flew my Pike Precision with 1.2 kg of ballast and my Needle 100. A good practice session for F3F in big conditions. Here are the pictures taken by Pascal Tournache:
