jus sounds like u werent tuning it properly your the first person ive seen on these forums to have such problems and contiuned to have them with that engine, yah it does need work everyday to run it is picky, but come on, you cant expect nitro to be plug and play like USB ports or Electric ^_^ If you dont want the engine ill take it off your hands no prob. And get a better battery than those cheap 1500's they give u for the charger, it doesnt even have enough punch
