My brushless Revo

[Finnster]

Hmmm....

So mixed results. I got it my gears and got it finshed, but the ESC is still having trouble. Even w/ 16 cells and 16/51 the top speed was ~25 mph. Very torquey, wheelies easy, but just no speed and a lot of stuttering from a stop.

I ran it for ~5 min, the checked the motor and esc temps. The motor was ~125, but the ESC was 200! Def something not right w. the 9920. Crap.

I was expecting 40 mph+, this is reasonable right? i think I will have to send the Bk off fopr repair or get bite the bullet and get a new ESC, maybe a Q125.

I really only see 3 esc that can handle 16 cells. The Bks, Q125 and the MGM 160. I guess the Q125 is it although I'm a bit annoyed with the heatsink thing.

Thoughts? I had replaced a bad cap on the 9920. Works now, but not perfectly. WTH would cause such high temps? I'm worried perhaps the FETs are messed or something major like that. So smoke or burned components that I can see. BEC jumper is removed BTW.
