Planet-Soaring blogspot passed half million visits

Image
Since I migrated to Blogspot very end of 2009, Planet-Soaring just passed the half million visits. This is a good achievement considering the fact that it is not a professional website. But it is still an huge amount of work and this statitistcs and all the encouragement I get is great rewards for me.


EasyStar 2 RR review in Modèle Magazine

My review of the EasyStar 2 RR has been published in the french specialized magazine "Modèle Magazine". It is a 5 pages article, and the pictures look great, thanks to the photographer Vijay Balasegaram, my work mate.


New video of the Willow F3F

As promised, here is the video filmed last saturday.

Willow F3F with 700g of Ballast

Image
Last Saturday, before the bad weather reaches east of France where I live, I drove to a slope to enjoy the sunny weather and the south wind (about 30 km/h) and try the Willow with some ballast.
During all the afternoon, I used 700g of ballast (which was the maximum I had with me. Now I can go to 900g). Ballasted, the Willow felt still light on the stick, and didn't show any noticeable bending of the wing which is a good point. I tried different turn styles with no difficulties. The Willow likes the "half roll and pull" where agility is a plus. In EM, it is fine but not superior like some planes where the section especially contributes to the acceleration with load of ballast like the Alliaj HM or the Pike Precision (to compare with planes I know well). Gain of altitude was great and the thermal position of the flaps+ailerons works good.
Speed position bring also some additional speed, but needs a bit more snapflaps to compensate the lower camber of the section for equiv…

TBS: the road trip continues ...

And Team black sheep posted 2 fantastic videos superbly edited, with a nice music, in brief a great moment. The first one is filmed around the lake powell located on the Colorado River:





The second video is shooted on the california coast, near Pescadero at the Pigeon Point Lighthouse


Video: Willow F3F

Editing was faster than expected, so here is the video, taken this week-end:

Willow F3F maiden

Image
Last week and this week-end, I flew the willow at my local slope in light wind condition. With 2.480g flying weight and a CG at 103, I found the plane to be good, just needed few down trim, so maybe the idal CG is at 102mm

What surprised me is that the Willow feels light at the stick. The agility on the roll axis is really great, it's grippy and precise. I followed the recommended settings for the snap flaps and elevator, and it appeared a good setting to start with. In turns, the Willow keep energy well, at the condition you don't pull too much the elevator stick. It should be good for EM turn style, as I feel could feel its potential on my "flat" slope which is not appropriated for EM.

I also has the chance of thermal while trying my new altimeter probe on my JR Propo XG8. Thermal position of the flaps+ailerons give more lift without bad behaviour. The plane clearly slows down its cruise speed. Circling is no brain, and I could gain a good 215m of altit…

JR Propo XG8 DMSS Overview

Image
For few monthes, JR propo is now proposing its own and proprietary 2.4 ghz system. After releasing the XG7, JR introduced second half of 2011 the XG8, a totally new 8 channels radio, and followed soon by the XG11 already presented end of 2011, and more recently at the Nuremberg toy fair in February 2012.

For this new radio, like for the 11X/DSX11, JR Propo really broke the mould and came with a very modern and innovative transmitter shape. From my knowlegde, JR gave the chance to a young designer to propose something really new. The radio looks like it is inspired by the movie "Transformers" and gives to the radio a very strong visual identity.

The XG8 is not only a nice looking radio, but is very ergonomic too: the grip is the best I've ever held. In addition with its 770g, it is very light. The position of the stick doing a opened angle with the case is ideal as a thumbs radio. It's light, It's grippy, it balances well, it's ergonomic, in brief, I like a …

New DS World record with 498 mph

This means 801 km/h, or mach 0.65 ! This is just crazy. This new record has been established by Spencer Lisenby with a Kinetic 100. The 500 mph barrier will be broken for sure ! Congratulation to Spencer for this new achievement.

E-Rotmilan maiden

Image
Last saturday, I had finally some time to fly my E-Rotmilan. And the maiden flight went bad because of my motor/esc/propeller setup. Before to fly, I did a short running in of the motor and ESC, fixing the fuselage robustly to a table in the garden. The heat schrink tube around the ESC melted after few minutes of short periods of use at a very low power (10 to 20% of the power). The ESC entered in température protection mode and stopped.




I changed the heat schrink tube before to go to the flying field. After checking everything I launch the plane without motor, then started the motor. The climb rate was good, but quickly the ESC entered in protection mode again. After that I noticed that the brake was not working, despite I programmed it using the USB link and the software Castle Link. I did few climbing but everytime the motor stop quickly, so I decided to land and return home to analyse.

Remember my post regarding the setup, with the simulation using eCalc. I finally decide to buy …

What a nice video in a mythic place ! This recent video from the team black sheep during their road trip in the west of USA is superb (once again ...) !


Willow build log #3

Well, Last time I stopped the build log at the moment to glue in place the inner nose with the ballast tube. This operation needs some preparation to garrantee a good positioning and aligment of the nose. I protected the parts with some transparent tape, them insert the inner nose in the nose cone with a thin plastic film in between. the fixing area of the inner noe is in fact a layer of rubber. According to the designer this is great to absorb the shocks and can still be glue with epoxy, the wood tray embrassing the ballast tube providing a deep and solid fixing into the fuselage. I used 10 minutes epoxy for this operation, then immobilized strongly the parts with more tape while drying to avoid any dis-aligment.




Lets start with control rods and servos installations. Control rods are made from 2.5mm quicklink with a metal clevise soldered on one side, and a second clevise screwed and glue on the other end, the glue is to eliminate any slop on the command. The rod is rigidified with a…
