L39 Albatross - nice plane

This is a 64mm version and I modified it to 68mm EDF. Slightly enlagred the motor area with a cutter is enough. I also use 4s 2200mAH and current is under 40A (to save my 20c lipo). The design is great as the front gerar is link with the rudder. The functional rudder makes landing more fun as the sidewind is now not a threat.

Flied her 10+ flight today and she is fast. Take off distance is less than 5m. Having a high wing aspect ratio, this plane has no tendency to stall, despite a heavy 4s lipo.

Freewing F35 now 200+ flight

The stock motor completely lost power in air. Luckily, the BEC is stil functioning and land her safely. Opening the motor bay and find the motor extremely hot. The strong smell makes me think the motor or the ESC is burnt. Everthing is stock and nothing different from previous 200 flights.

The only think I found is the previous 2 packs are getting slow and I think the Lipo is bad. THe motor was found burnt and siezed. Post mortum will begin to see what cause the motor sieze. Bearing? Broken magnet?

Prodesign F18 composite EDF

Just compltete my build of this high quality ProDesign F18 single 90mm EDF. This is my second F18 and the scale is much better than the Starmax F18 90mm EDF, which has a disproportional long nose.
I like the elevator control design which is strong and precise.

I plan to fly her with ~1000W.

Easyglider Aerial Video

Very strong winter monsoon. Still quite stable. I was so lucky that it did not crash as I forgot to put in the wing joiner screw !

Plan to take HD video soon, as this test platform has been tested for dozen times. Next I need some idea to protect the expensive HD camera..... still under warranty..

Easy glider 2m FPV

Very efficient modification with 8" propeller. Flight time over 15 minutes with 2200mAh 3s lipo.

FIY Twin EDF SU47

Quite scale looking twin 55mm EDF . The kit come with 2 tiny 55mm EDF. Since I got lots of 64mm EDF, I drop in 2 and they are right fit and with correct C.G.

The front battery compartment can house 3s 2200mAh lipo. I plan to go for 4s for fasting scale like flying.

With 3s and Jpower EDF, the thrust is 650g @ 36A, good efficency of >1.6g / W

All flying weight is around 750g.

I plan to put a 4s lipo and current will be 56A, with thrust over 950g. For cheap 20c labled lipo, I'll limit the throttle to around 40A max.

Maiden is a sort of perfect. She flies great with absolutely no tendency to stall, as what front sweep wing should behave. .....

Maiden video pending .......
