under or over geared?

[steveo]

i always forget, motor and batteries of around same temp and esc alot hotter, my dog ate my temp gauge (seriously) so i cant give ya anymore info about temp, its a c-50 motor i dont know what wind it is, its not the one for the e-maxx. gearing 18/70

the 9920 seems to hold up well, even on 18 cells and it wants to take flight
