did some more reading,learned that waiting between flights is a must. i did'nt. popped in the second battery quick as a bunny.i have looked very closely at the esc. and the eboard and definately did not see any scorch marks either front or back.also looked at the wiring to see if anything there had burned did'nt see anything i am going to go with the lesser of two evils and go with replaceing the motor.next question is: do the 2 halves of the frame need to be completly seperated to replace the motor?,and is seperating the 2 halves going to give me any surprises with regards to what it will do to the main shaft or anything else?thanks for the hep
