Update of the software was pretty quick ! Olivier Segouin released the new version of Servormances that includes the test results of the JR DS168, Graupner DES448, Graupner DS3288, Hyperion DS095, and the new kid of the block, the MKS DS6125.
After reselling IFS, and acquired Weatronic, Graupner just released their "home designed and developped" completely new 2.4 system called HoTT (Hopping, Telemetry, Transmission) with up to 75 channels in the 2.4-GHz band.
It offers integrated telemetry in real time, is fully programmable with the help of the Smartbox (very similar to the Jeti Box).
- Simple, extremely fast binding - Range test and warning function - Low-voltage warning - Extremely broad receiver operating voltage range from 3.6 V to 8.4 V (functional to 2.5V) - Failsafe, free channel allocation (channel mapping); mixer functions and all servo - settings can be programmed simply with the HoTT-Smartbox - Binding of any number of receivers for channel expansion (maximum of 32 channels) - Up to 4 servos can be controlled simultaneously as a block with a signal repetition time of 10 ms (only digital servos!) - Maximum immunity to interference through optimized frequency hopping and broad channel spread - Intelligent Data transmission with correction function - Extremely fast rebinding, even at maximum distance - Telemetry analysis in real time - Over 200 systems can be used simultaneously - Future-proof through update capability via USB interface
Apart the update capability via USB interface which is really a nice feature, the rest looks like a jeti system !
I sent one of the DS6125 I won at the Viking Race to Olivier Segouin (Servormances team member) who tested the servos yesterday. As reminder, Servormances is first of all a test protocol that allow to test servos in the very same conditions in order to be able to do true comparisons. Servormances is also a software with a very friendly interface (in french only, sorry mates !). Last update is from June 2010 and can be downloaded here: http://www.aeroglide.net/2010/06/mise-a-jour-servormances-2/.
Currently, Olivier is doing some servos tests with the Graupner DS3288, DES448. I guess a software update which includes also the MKS servos will be available soon.
As an exclusive preview, here is a comparison of the MKS DS6125 with the current wing servos references, from my point of view: the Hyperion DS095FMD, the graupner DS3210, and the Airtronics 94761Z.
To make it short the result is that the MKS DS6125 is comparable in term of max torque and speed, but surpasses all other servos in term of precision, positioning, neutral position, and bending under load. This is confirming the first user feedbacks.
This is all the characteristics that we are looking for on our competition gliders, so I predict that this servos will become rapidly the new reference and a best seller.

With the winter, It's time to change of flying machines :) ! I started to fly a quadricopter for 2 weeks. Apart gliders and motogliders, I had never tried helicopter or multicopter. This is a pretty exiting piloting excercice. The road is still long, but I start to be a little bit more confident, so today during the lunch break, I tried some Aerial Pictures with a home made AP Mount made from carbon tubes and coroplast, and the GoPro. Here is the result.
Except that we see the mount and the foam protecting the propellers, the result is quite nice. Tonight, I will build another mount in order to have nothing in front of the GoPro.
These 3 pictures From Jean-Claude Faure has been taken in the south of France on the slope of Vernègues (Near Aix en Provence) during an F3F practice. The glider is a Dingo (3m wingspan) so you can compare with the size of the Vulture !!!!!
It's a very sad news I just learned from our Spanish friends. Joao Costa died in the night of Sunday to Monday, from a heart attack. Joao was the most French of the Portuguese or the most spanish of the Portuguese because it was perfectly trilingual. We will miss your kindness and good humor, Joao! Rest in peace up there. My thoughts and condolences are with his family and loved ones.
Last week was organised the Dyno-fest, a dynamic soaring meeting over 2 days, in california. Weather was great and lots of records has been broken, plus lots of personnal bests ! A concentration of higly skilled pilots, and amazingly fast planes !
I decided to merge both side in order to keep the best of each and combine them in order to obtain a single site where you can find articles, but also breaking news posts, video sharing, etc … You can still access the old site (pierre.rondel.free.fr) but the front page will not evolve from now. New articles will be announced on the unique front page which is the blog page. The domain name Planet-Soaring.com is redirecting to it.
I hope the new site will be more active and alive and will continue to provide you interesting information like it does for 12 years now !!!
This is the first JR 2.4 radio that is not using Spektrum technology. The new techno used is called DMSS which stands for Dual Modulation Spread Spectrum. According to JR, this allows to choose between FHSS or DSSS.
The XG7 comes with telemetry system which monitors receiver battery voltage. When the receiver battery reaches a pre-set level the transmitter will beep. The receiver battery voltage is also displayed on the transmitter.
The transmitter will be sold in UK. No idea about the rest of Europe as JR is distributed through Graupner with has a partnership alerady with Weatronic and IFS.
This new plane manufactured by Palo & Miro Polonec (Miro Model) . Miro Model is well known in the F1E (free fligth) world. For example, pilots from the french national F1E team are using Miro Model planes.
This is a crosstail sailplane with a 2.95m wingspan and a DP section. It has a original wing planform.
The plane has now a long trip from Slovakia to its new home in France in the coming weeks. As soon as I receive it, you will have a complete presentation in details.
A nice video about the Swiss F3F Championship that was organised last week-end in a nice place (Hahnenmoos/Schalmigrat)
Not too much wind apparently :( ... Flying also in the Alps, I would say that October is a little bit late in the season. The thermal breeze is not blowing strong in Fall. That's why we are organizing our club competition beginning of September, not later.
what is good if doing F3F in slope like Hahnenmoos or the Col du Glandon is that the breeze is consistent and the thermal effect is very small. As a result Col du Glandon is currently the fairer place to fly F3F in France. The disavantage is that the probability to meet F3F condition is lower compared to region like Toulouse, or south east.
Yes, my new toy is not a sailplane but will complement my EZglider for aerial photography. I finally didn't resist to buy a quadricopter. To begin, I choose the Gaui X 330 which is affordable and, in its second version with Scorpion motors sastisfies lots of happy owners.
Assembly took an evening. I'm now waiting for the camera mount + gears which should arrive soon. The Gaui will take on board the Go Pro or the Sony W350. I hope to obtain good result as soon as I will control the quadricopter.
This will be a complete new experience of piloting for me. Perfect for this winter, when F3F is doind a break.
Yesterday (The 9th of october 2010) during the 3 round of the last F3F french league competition, I broke the french record and at the same time broke the 30s barrier with a amazing 29.92s !
The wind was between 18 and 22 m/s on slope A in Laurac (VKR slopes), with low clouds. My gain of altitude was average, and the first 2 laps were around 40s. But something happened until the end of the flight. It was like having a booster or a rocket on the plane. The wing were bending during each turn, but I didn't care :) !
I should have the video in few days because a modeler filmed the flight in HD with his camera.
I'm under 30s .... unbelievable !!!!! I joined the club :) !
