I use the 15t. Plenty of power/RPM

2.5mm MOD 0.4 Pinion Gear Set
[250Pinions] $5.99



This pinion gear set was designed specifically for the Scorpion HK-2206-3900 motor that is used in the Trex 250 Helicopter. Included in this Pinion Gear Kit are 3 gears, one 14-tooth, one 15-tooth and one 16-tooth. These pinion gears are the set-screw type, and also include an allen wrench that fits the set-screws.

In addition to fitting the Scorpion HK-2206-3900 motor, this Pinion Geat Set will also fit the stock Align Trex 250 motor for those of you that want to be able to fine tune the head speed of your helicopter.

My Posts This: Topic  Forum		Anyone know where you can get a 17T pinion for the stock motor? Seems to me you would get similar performance from the stock motor with a 17T pinion to the Scorpion on 15T.
