i know it's not "legal" as per sanctioing body rules, but i have a mamba max 7700 and it's incredible; i experience no cogging under forward operation, the resolution and TR is wonderful. The only cogging i've ever experienced with it is when bashing, going from reverse to forward, there sometimes is a slight hesitation when it syncs back up, but the power is incredible.
now to join you guys onroad ; )
