Me. I have an rs4-2 I had it running so frigging perfect until servos started acting up. I could pull it out of my box.. Prime it. Put glow warmer on and pull the starter one time and it would run PERFECT!. Now i have messed with the carb because i thought thats why it was dying but it was the servo sticking it shut. So now im lost. I have tried and tried and tried.. And even when i do get it started It will run great until the motor gets warm, Then it seems to lose power and will eventually die at low rpm when im not gassing it wide open. But until then it sounds good, and smokes well and has lots of power. Did i damage something major? or Is my tuning skills not up to par. Please help rc gods.
