3000 mA Ni-MH & 5000mA Ni-MH, both 7.2v. Nothing exciting really.
Found a way to mount the heat sink fan on the motor finally. Used my third FTX stock brushed motor. Went ok yesterday for both batteries, we even started having fun. Today it's back to sluggish pace, can barely reverse. Took out the FTX motor and fitted the Abisma Thrust Eco 15T I ordered. Bench test fine. Ran it on grass in the park, same problem. Smelled burny and after only 2 minutes in the park it had burned out, no smoke or anything, just dead (tested by connecting battery directly, having removed it first).
Found a lump of metal jammed in the mech. It fell out after some fiddling. Not great, another part to go back to the RC shop.
Scorch marks inside the heatsink.
I avoided brushless as I did not think it suitable for my kid, but would this be a more reliable option.
Can anyone recommend some dependable reliable guts (motor, ESC) in both brushed and brushless form?
Going to give it one last shot.
