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?
I suppose there is something in the tail rotor that would explain why it turns on itself but I cannot understand why it doesn't take off at all. It looks like it has a pitch 0 as it was a CP heli...


Thank You

Sounds like you have a Blade SR collective pitch helicopter not a 120SR fixed pitch.

If you crashed, You broke something!
You will have to look the tail rotor wires over very well and find out if you broke a wire
or burned out the motor or something else.

The helicopter will not fly without the tail rotor.

Then take a close look at the main shaft and head assembly and make sure nothing is broken.

This link will take you to the Blade SR forum. You may find an experienced SR guy there that can help you.

Hope this helps.

Maybe it can helps someone other...
In the end I found that the tail rotor was assembled reversed so the thrust was not effective.

Check to see that the tail motor plug hasn't pulled apart.
