BD5 Pusher Glider


BD5 is my first fiberglass body with wooden wing. Wingspan 1.3m. Weight 650g. AUW 810g.






Must add 5-10 degree downthrust angle

The elevator flap is a bit weak.






Equipped with cheap towerpro 2409 1800kv? 200W outrunner.
With APC 8x5E, the takeoff and flight is perfect.

Because of the low wing loading, it glides so great. Rolling rate is slow because of the large wing span.




Low level loop during sunset resulted in crash with broken nose and wing. Fixed and in service now. I am surprised how good the fiberglass resist heavy crash.


2008 : Finally retired after a heavy head down vertical crash resulted from fracture recevier board that killed the elevator channel.
