Hello, i've had an e-maxx for a while and first i had the original 550's and after while they died so we got some new, they also burned up or what ever happend to them, I think ive had to replace almost 6 new motors because they just keeped dying. So after a year i bought the kershaw designs 700 ho (works great) but then they also stoped working but after a longer time. So I got some new ones and they have just started to die. they are smoking and smells like burned electronics..

I dont want to buy anymore motors because i dont know what the problem is. why does all my motor die so quick? they die at the same time..
Please give me some answers of what i could be.
