小齿轮3毫米/ 0.5M 14T（1个）
Works great on Alpha 250 shaft for a Esky Big Outdoor Lama brushless/boardless conversion.
Head speed just about perfect with this 14T pinion. Also purchased 15 and 13T versions to adapt headspeed to different blades and loads- 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 !
I will use this on HK 450 with motor TP 450 size 241509T Brusless Heli motor 2700 Kv. I din't any tests because I waiting the heli arrive on HK stock. But apparently should be a good match.according with the characteristics that I saw on the remarks from this motor.
