I was driving my 10th tank through my Mayhem today. The stupid thing glitches whenever I go WOT. It will just turn left or right. I nailed a block wall at almost full throttle , I barely was able to apply the brake before it hit, which didn't slow it down much if at all. This car is tough though, all I broke was the left front shock. I have a JR XS3 radio with a RS300 receiver, soon to be a RS310. The guy at the local Hobby Town said that he's been having problems with the same receivers in LSTs lately. He called Losi and one person admitted having a problem and that they're changing our the RS300s for RS310s, that's why I'm getting one soon. So, I had the LHS guy call JR/Horizon Hobbies and they've sent me the RS310. I'm hoping this will fix my problems. Anyone else have any other suggestions on glitching prolems?
