thankyou for that, and i'm sorry to here it happened to you. i am going to check my batt connections tomorrow, this is not the first time that this has happened as i read in this forum but the other cases no one new the cause. and yes a throttle return spring would of returned the throttle to idle. i just installed one on mine yesterday since i had a spare from one of my savages. i was going to run mine tomorrow but i think that i will hit the hobby shop first and get the batt pack.
