This is an excellent pinion very good quality, nice price and with grub nut what else can you ask for and the head speed it gives to the heli is just insane.

the 0.5m is wrong measurement, 0.7m the exact size

- material: brass

- tooth pitch: 0.5M - standard in 450 helis

(with constraints, may also work with 48DP, 5% difference)

- fixing: by grub screw

(flattening shaft by multi-tool grinder helps)



Pay attention to correct clearance of gear !
