Project OverKill (hehe)

I'm with azjc on this one.. I started out running a C4 9000kv motor that just seemed like small portable heater. Lutac, I'm sure your Mega ACn16/15/1 made a fair amount of heat no matter how efficient is. How long were you able to run it before it got too hot? I just bought a Neu 1115 1D (5700kv) that I'm going to try to stuff in another 1/16 project with a custom chasis. The thought is to run it on 3s and gear fairly high due to the expected torque output of such a long can motor. I will post some feedback here.

The Mega didn't get hot at all and most of the time I ran on the track. I was using a 16T pinion with the 56T spur. Too fast for the little track at Xtreme RC Addicts. I now have a 6 pole low Kv motor which is the only motor that the Kontronik Beat 70 Car actually works and I have a nice 22T pinion to get some speed out of the Recoil and one guy at the track could not believe how smooth my Recoil is. That guy btw runs the C4 9000Kv+ motor in his Recoil and it heats up pretty good. I have to see if Artur can fix my 60A controller which was the only one actually turning the Mega ACn16/15/1. Not even the Beat 70 can make it turn. I made a mistake on the timing of the 60A controller and it burned a couple of FETs.
