So the motor shaft on my 400dh is kind of short for the trex. I'm using a like90 pinion and can only put it on about half way before it can't reach the main gear anymore. Even with green locktite, the pinion starts to slip after just a few flights. Now the pinion slides over the motor shaft quite easily by hand.

Are there longer pinions that work better for the trex? Or are there pinions that fit just a bit more snuggly?

Thanks
Ryan

400dh pinion
Hi Ryan;

I found the 9 tooth pinion gear works best for the 400DH, Align now sell a pack of 9,10,and 11 tooth gear set for $5.99 with the set screw, it fit perfect on the 400DH shaft.

Good lucks
