450 450 acting up again

[D.O.G.]

I need help with my the 450 new deli-ma. My main gear,motor and blades spin but my tail doesn't spin after certain RPM? When spooling up, everything is tight and right. Once I start spooling up, til I get to a certain rpm, the tail blades stop spinning. I've already change the auto rotation gear and the main gear hub Twice and still nothing. Any idea anyone?

Broke torque tube?

Broke torque tube?

I'm sorry to mention that it has a belt drive unit and the belt is not broke or teeth missing?

Only thing else that it could be is the one way bearing. Without actually looking at it anyway.

Hold the Head still and turn the tail by the blade grip see what turns and what dose not .
tail hub set screw loose

I did what you said and I seen that the belt drive gear/belt spin and the gear underneath doesn't spin. Good call and thanks super bad I didn't even think to check that gear assembly out. I never had one go before. First time for everything.

Thanks Tony. I wasn't sure what it was called. Belt drive assembly gear sounded good to me Lol

Glad you found it
Sounds Like it sheared the pin off in it

That sounded like the time when I was at Hotter n Heli with the Protos Mini.
