My Mugen 5S 1700KV burns around 240mA/minute
My Mugen 6S 1400Kv burns around 190mA/minute
They are both faster than they need to be.
In addition as you go up in voltage & down in motor KV the car gets smoother. Nothing is smother than my 6S setup.
I've just built a Mugen MBX-6 with a Tekno V3 conversion. I'll be running Zippy 5s, 5000mah 30c batteries, along with the Tekin 1700kv system. Could you give me an idea of where to start out with gearing? Are you using mechanical brakes, or motor brakes, as I'm sure this would make a difference in motor temps. What kind of temps are you getting on the motor after 10 minutes? I'd like to get 15 minute runtimes so that I can run with the nitros. Thanks for any advice...
