RE: mamba is good...no?
I want to see him run this motor and I want to see the results.. I looked at this motor when it first came out but after a few calls to Castle and talking on the forums, I kept my 5700 in my Rustler.. It already too fast for the truck with3S, so I just run on 2S now... Obviously the motor won't spin loaded anywhere near 100K rpms, but even around 80K or so its not long for this world..
Its his money.. let him try it.. but ask yourself this.. don't you think that the guys at Castle or even the guys who do the speed runs thought about this motor.. there is a reason they don't use it.. Low KV and high voltage is the faster way.. not High KV and High voltage..
