I've come from testing my MMM COmbo 2200KV at the track (muuddy) this morning, and all I can say is flawless performance!! high torque , high speed, super low temps; geared 20/56 (38-39mph) motor didn't go over 45ºC (113ºF) weather temp about 15ºC sunny (60ºF), MMM fan didn't see fan turning on (when body out, can't say on ride). I opened the body some times, but the motor was extremely cool so I continue runing almost non-stop!
The SPC 8000mAh 12C did very nice, high punch, low temps during rides (78ºF) very high duration time, much more than the titans or Kershaw, also 5000 mAh 25C Intellect went nice until I hit aa vertical steel rod of the circuit and broke pushrod, arm and differential yoke, but before the Revo resist a hard punishment and uncountable hard roll overs flawlessly!
I could deplenish the 8000 SPC pack, I stopped before it get to 6 volts (6.20V aprox) because the car lost speed, so I couldn't test the cut off (manually set at 12v, I think to low for 4s).
This pack and a little of the 5000 Intellect (15 min) give me an d about hour and a half runtime with short breaks (so easy 50 min with 8000 pack)
Provisional instalation, no good place for the switch and double sided velcro for the MMM that worked perfect, nice cusion, and didn't move in all the crashes and rollovers, so very nice performance , maybe the "flex" and some free movement of the velcro gives nice protection.
