RE: E-REVO up in SMOKE
If you are going to replace the Titans, gear down to 17t pinions. Geared 17/68 I can run a full 20 minutes with my 2 2s 6000 lipos (on dirt, short grass) and my motor temps were 170, esc 125 and the lipos were barely warm to the touch. This is my second batch of Titans, too. Send them back to Traxxas and chances are they will replace them. The E-Revo is a bit overgeared IMO out of the box. Also make sure your spur/pinion gap isn't too tight.
