Just cruising around meeting new friends and shareing the hobby, running EMAX's new PM1806, the lack the grunt but have a hardy 3mm shaft (covered by a plastic housing, tighten to snug only as the have CW & CCW threads) unlike most in the same class of motor that are 2mm, the frame and FPV gear are heavy for these motors, Diatone ET200 carbon frame 39g, ultralight DIY FPV combo 12g and a 1000mah batt should improve things.
