I recently just acquired an LT-711 HawkSpy...

I had some good first flights and the thing flew like a champ..

One bad crash later, busted main blade...

I tried to super glue it.. Dumb move... Got a good flight then another crash...

Not to be deterred, I ordered some replacement blades.. Waited patiently (shee yea right!! ) and they arrived today..

Now it doesn't have enough power to lift off... Good batteries in the transmitter and a full charge on the chopper...

I think the crash might have thrown something out of whack... There is a definite clickity clack when the rotors start to spin when before it was a smooth spin-up....

And when I hold the chopper and rev up the power, I can feel a definite vibration...

After pulling off the side metal panel, I found the problem...

Seems the gear (green box) that controls the upper rotor got munched up pretty bad (red box)...

My question is, what's the best way to replace that gear?

And is this the right replacement gear??

Any hints, tips or advice would be most appreciated.
