Walkera Dragonfly 4

[Margel Cauvier]

No power for lift off, is it the battery or the receiver? The helicopter lift for about 4 inches from the ground, it is like the rpm is to low for real lift off.
I am a new pilot, if you have an idea, please help me. :o

i own 4 #4s
mine are all fine
one thing you could try is connect the battery direct to the motor
BE CAREFUL!!!
if you try this, the rotor will go full speed and it hurts!
when i test a motor like this case, i just clamp the frame, and just touch the connectors together for a sec
its all you need to see it spin
too bad we're 100 miles apart
i would have checked it for you
