OS 91SZH and revolution

[sapca]

Hello,

I have the revolution with OS 91 SZH engine.

I have put the 0.2 mm shims between the engine and the engine mount

I the manual they say that you have to put the 1mm plates and the 0.2 mm shims.

When I do that I have allot of plain between the main gear wheel and the Clutch bell, 12 teeth.

Is this normal ?????

Regards

Hi Sapca,

I am not firm with the measures of the OS 91 SZ enginge, but since we are using a bigger modul at the REVOLUTION gear (compared to other helis), you should be aware of enough gap between the pinion and the main gear wheel. When you are turning your main gear wheel forward and backward, you should feel and hear the gap!

Best regards
