i found abs>pla, but i guess nylon or polycarbonate is even better. i use tpu for the feed

this copter is a blast to fly, flips & rolls very fast, insane yaw rates are possible. frame is tough and can take a hit. I tried with PLA first, but it is heavier and tends to shatter, even though it appears tougher.

Print at 100% infill to get maximum toughness. Weighs about 6g. use 380mAh batteries, ~4 minutes airtime.

( i prefer these ones over the 3 blade props linked below, but you need a 0.9mm or 1.0 mm drill to make them fit on the motors)

dont go heaver than 12g per battery or you will really start to feel the weight. I found that 500mah lipos only give 30-45 seconds more flight time, but way slower throttle response!
