for scale flyer to 3d maniac
for 50 (10mm shaft), $400
for 90 (10 and 12mm shaft), $600
included skookum sk360, usb interface, rjx fbl head and free setup.
the 50 head is used but still in excellent condition. the 90 is brand new. can be used for any heli ccpm or non-ccpm eg raptor, caliber, hirobo, trex, avant, jr, outrage, extreme etc2.
this is my spare fbl. for 3d, u can use 14 deg pitch, fly level flight even on windy condition and it will give u 20% more power due to less drag. for scale, u can set it to feel like it has super soft damper and u can let it auto hover for 30-45seconds.
