Something broke but what?

[mauog]

Hi all,
I was flying with my Blade 120 SR when I crashed.
I tried to recover flying but the heli has something wrong.
If I push up throttle it starts turning on itself like the tail rotor doesn't work.
Moreover I can give all the throttle I want but it stays stuck at land.
I cannot see any damage to tail rotor or blades.
Do you have any idea about what is wrong?

Thank You

M.

The 120 SR is a fixed pitch heli with a motor driven tail rotor.

Are the main and/or tail rotor blades spinning when you give it throttle?

Does the swash plate move at all when you move the cyclic stick for forward/back/left or right?

Check out the 120SR forum and there will be all kinds of help available there.

It looks like a CP heli with pitch 0. I can understand that the tail rotor is spinning less than usual so it turns on itself but why it doesn't take off at all?
