Teken R-2 w/ 55T, problem

[Mule]

I ran it for a couple charges and had no problems. I ran it last night and started getting little surges almost immediately. It would be crawling along real slow and then lurch forward all of a sudden. What the heck is going on????? It did it going straight and turning.

I'm ready to get a Sidewinder 4600 combo w/ BEC....... I would like the extra speed on top end..

I have some weird ESC and a 65T in my TLT and never had a single problem.
