Hi there ive been on here a while now reading your guys post. Learning lot i have a ul-1 that ive been working on and in the mean time iv been playing with my hammer ep. I just put a brushless setup in the hammer and am having problems. 3600 kv and a sky wing 60 amp esc running a 14.8 3000 mah lipo went great for a while and now nothing. The esc says 2-4 cell lipo. Im not sure if i fried the esc or what when hooked up the only thing that works is the ruder. Any ideas guys thanks much jesse
