I hope this is not common problem! after having some fun with my 3 month old e-maxx with castle motor and esc running on a 4s 4.5 i stopped for a while only to hear someone shout, hay boy ya smoking, then flames. I quicky pulled the batteries out but the esc is cooked, the gearing etc is good i was only doing some jumps to no load on anything. Any ideas? i have a picture but being new can not post.
