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.

That's a bit big for a buggy 21-20 may be better what turn is the motor?

I've got a 26t I can also use, but still can't see there being enough clearance to fit both screws through the mounting brackets and into the motor.

page 42 in the manual shows you what pinion you can use with what size spur. use the 2.58 ration chart
