Quark 65 amp controller
 

Is this controller too small to run a Feigao 8xl on 3or 4s in a 1/8 buggy ?

I have sucessfully run the Quark 80 in a 1/8 buggy with no issues, but the 65 seems on the small side IMO.

does Mike carry the 80

I would yes, too small. Email Mike to see if he has any around.
