Pocket Radar review

Aeromodellers have always been attracted by speed, if not addicted. But when you come to the speed evaluation, you quickly discover that people are very often optimistic (like measuring altitude). This is why a speed radar is interesting for our hobby.

If you don’t want to invest in an expensive radar gun, there is now a very convenient device that do the same for less money, but especially that will fit in your pocket, so that you can bring with you all the time. It has been made possible by using a much smaller, flat antenna to create the same type of signal that the horn creates in a radar gun.






I bought one for me few months ago. My objective is to have a means to measure the speed of my sailplanes when DSing.

The Pocket Radar has the size à a cell phone, and is able to measure the speed of moving objects from 11 to 600 km/h. It uses 2 standard AAA type batteries and comes with Alkaline batteries included. It comes in a very nice box that will protect it during transport.

Its accur…

Good flying session with the Ambrosia F3X !

Despite cold temperatures, I spent the afternoon on the slope to fly the Ambrosia F3X in good wind conditions (Around 40 km/h). I flew it with 650gr of ballast over the 1300gr it can carry.

If I would have to describe the Ambrosia is very few words, I would definitively say: “It tracks extremely well !“. Thanks to the fin and the full moving cross tail, the Ambrosia is a pure joy to pilot. It is fast, but especially, it is easy to fly fast, which is a very good capability from my point of view. You don’t have to fight with the plane, to correct trajectories all the time.

I did hundreds of laps and turn, and I have been very impressed by its behavior in Energy Management turn style. It is so easy, remains stable, go high without slowing down. The elevator is smooth and very precise. No drag induced by a control surface, the full tail is always perfectly aligned.

The Ambrosia carried the 650gr easily, and I think I could have put more ballast without problem.

2.4 Ghz Survey Results

Image
The survey ended few minutes ago and gave interesting results. Thank you all for your participation to the survey !
Before to comment the results, it is important to mention that the survey concerned mainly Europe, and especially France as you can see on these per country statistics for last month.



Let’s now have a look to the results:



Without surprise, Futaba FASST arrives in first position. FASST has been introduced at the beginning of the 2.4 Ghz, as the first FHSS system, and appeared to be reliable from day one apart few recall concerning the sensitivity to the temperature of one receiver chipset. But if Futaba represents 1/3 of the market, things could change quickly if they are not releasing the telemetry which is today the major weakpoint of their offer.

The surprise is the second rank of Jeti. Jeti was not particularly reliable with their FM receiver, but their 2.4 offer is pretty well designed, reliable, and Jeti is the very first brand to propose and deliver telemetry and v…

Snowy Grenoble

A Short flight above the south of Grenoble after yesterday snow falls. Unfortunately the GoPro was not fully charged so the video is shorter than expected.

Ambrosia F3X first flight ... almost !

Image
Well, the weather conditions were totally calm air, no wind at all with a temperature of 4° celcius. Hopefully, all the snow melted since last week-end, so the slope was accessible.

It was defintively not a weather for a maiden flight, but because I was on the slope, I didn't want to return home without launching the plane once, do a circuit and land.

Surprisingly the first flight was longer than expected and I was able to do few circuits in dead air, with flaps, before to land, very encouraging.

I have been able to see the good lift provided by the section, and the good handling of the Ambrosia, at very low speed, with no bad habits, no stall.

Now, I'm  waiting for better condition to see what the plane is capable. Maybe tomorrow I will drive 1 hour to go to another slope where the wind could blow a bit more according to the weather station  installed near the slope for paraglider.

Jeti transmitter and new glider receiver officially announced !

Image
Jeti posted a press release on their website confirming the release beginning of 2011 of a 2.4 Ghz transmitter family (which means not one but several transmitters) a also a brand new slim receiver especially designed for glider nose.

This is excellent news !
By the way, don't forget to answer the survey which will give us a better undeerstanding of the market share of each manufacturer.

Video: Team Black Sheep in New York city !

Trappy (Team Black Sheep) moved from his mountains to go to NY. Here is his new crazy video:

Survey: What 2.4 Ghz Brand are you flying ?

I thought it would be interresting to know the market share per brand, as we are in the middle of the war. Please answer honestly to the survey on the right of the page. The more I get answers, the more the result will be representative !

Flight above Lans en Vercors

Lans-en-Vercors is a village in the Isère department in south-eastern France, near Grenoble. After the heavy snow falls last week, I drove there to do some aerial pictures and video. Sunny weather but freezing temperature with -8 degrees (celcius).





Lans-en-Vercors is located in the Vercors a beautiful massif of mountains. The Vercors massif and surrounding areas are protected as a regional park (Parc Naturel Régional du Vercors in French). Some especially wild and remote places of south eastern Vercors are in a more protected area named Réserve intégrale des hauts plateaux du Vercors (Vercors high plateaus reservation). These mountains were used as a natural fort by the French Resistance during the second world war.

Vercors is a perfect place for outdoor activities: Nordic Skiing (One of the largest Nordic skiing system of Europe), Alpine skiing with 7 ski resorts, Paragliding, Canyoning and Caving, base jumping, and of course aeromodelling with one of the most thrilling competition o…

Sailplane Grand Prix

This is about Sailplane but not RC. "Sailplane Grand Prix" is new gliding racing format that take advantage of the latest techonolgies to allow the spectators to watch the race real time with onboard camera, real time simulation.

The following video explain everything with in addition superb video sequences. Unfortunately, it is not broadcasted on the main channels in France. Maybe some of you have seen it
