maybe you try a hobbywing hv (up to 12 s), or a suppo hv.

both brands are good, and not too expensive, you don't want to spend too much money. the hw is quite popular for 1/6 conversions, maybe you add a fan and some caps.

the suppo would be worth a try, too.

maybe the esc needs a startup. the graupner genius have that, you can choose between the direct startup of the ecs when plugging in, or after using the throttle (it has no on/off switch). give cc a call!!! for 400,- it's supposed to work!!!

btw, she's a real beauty!! great car!
