MMP spektrum sr300 question....

[hootie7159]

damn...well, tonight i was just running it in my backyard doing a suuuper slow full lock left turn and then punching the throttle and it would still cut out (but not as long maybe 1/2 a second) but if running it at WOT and doing turns and jumps it would be fine...just when i did the full lock turn/throttle punch...and this was WITH the cap added....sooo, i changed the servo (went from the s300 spektrum 100oz/in servo to the stock ten-t servo 55oz/in) and the stall was gone without the cap :) .... so i thought it was a bad servo.....but then i put it on the ground and did the full lock/throttle punch test and it still cut out (with the cap on) although it was only for a REALLY quick second.......now....after all this i decided to test the same thing with an ext rx pack and guess what?...no more power loss.....AT ALL!!!....but i definitely do not want to drive aroudn with 4 AA batteries strapped to the chassis...lol.....ah well....i'm gonna try a different rx just to further single out the BEC as being the issue........simplechamp, see if the mmp BEC stalls out with the cap on doing the full lock/throttle punch test.... Hey Bernie/Patrick/Thomas/Joe...any input on this problem????
