Super quality. Class product. Fits well for the Align T-rex 250 and HK 250 GT.
Thank you HobbyKing.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.Super quality. Class product. Fits well for the Align T-rex 250 and HK 250 GT.
Thank you HobbyKing.I will use this on 250 heli to lower the crazy head speed of my motor,Great for fine tuning 250 heli.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 !
