Which motor outdoors in 2wd 5.5,6.5,7.5
 

Just deciding what to put in the cougar for outdoors racing. What do most people use?

Too vague, amigo.

What surface? Length of track? Cells?

sorry for lack of info, using vampire 4000 35c lipo and to be honest dont usually swap the motor much so want something i can leave in for most grass / astro tracks

Ive put a speed passion v3 6.5 in mine. Should be plenty fast enough and smooth enough for tight indoor and low grip. They are awesome motors imho.

I already have a 7.5t, looks like majority are using one. At least saves me buying a new motor

With 4000mah 35c lipo I'd say a good 7.5 would be fine.
