well we were jumping a buddies "shell" driveway, huge mistake . and had been going fine for a while and then . landed roof first , it started making a wierd whistling noise. the noise seemed to quit and it still ran at this point, the whistling noise came back . and then the engine is just "screaming" . i shut it off pretty quick , i don't know what red line is inna r/c but i had to be close . that was it . so i look it over and 1.broken engine mount 2.stripped spur gear 3. broken carb. housing. so i just got off the phone with tower , and since i had it apart i ordered the 17 tooth clutch bell . pay to play right ? just had to vent, lol.
