Looking at the 3500KV's they seem to be the same as my current Velineons which are 3500's which are on my 3905 truck. My 3906 truck with the two 7L's , would it really be anymore powerful then the two Velineons on 3S's?? How would 6L's do they are 4096KV's and seem to have a little more grunt then the 7L's?? The RPM's though are a little over what the motors are rated though...
