Hey, i bought a batt pack at my LHS for my hyper 7 it was part number ofna 10202 and i tryed to put it in my 7 and it was the wrong one so tomorrow im going to take it back, since i already paid for it i would like to see if he had what i needed in stock. i think i need a flat pack. but i would like to hear from you all so i dont waste yet another trip down there. also ill just throw this in there i lost a screw where the motor mount screws to the frame from the bottom side the hobby shop and i have looked everywhere for a part number and i have not found one so if you all know that that would also help me. thanks for your help.
