Schumacher Cougar SV2 pinion gear help please

[jimny82]

Hi,

Wondering if anyone can help. I'm trying to put a Speed Passion V3 brushless motor in my SV2. I have a HPI 28t pinion gear, but when the pinion gear if fitted to the motor it doesn't allow enough clearance to fit both screws through the mounting brackets and into the motor.
Do I need a Schumacher specific pinion or something?
Any help would be great, thanks.
