Submited By: Heli_Flight on 06/12/2007 Pros: These are great fitting pinions. The pinions are crafted to perfect symmetry. They fit smoothly over the 3.17mm motor shaft. The little screws hold the pinions firmly in place and with out worry of becoming loose. Cons: I have used the 11T pinion so far. It ran great in a 400 class heli with a madusa motor, that was until the 15th flight. The metal in the pinion started to give. The metal is very soft. The pinion started to strip before the cheap plastic main gear that drives the principle axis or main shaft. I bought this cheaper pack and I also bought the three pack made by Align. Stick with the Align pinion, you'll get more bang for your buck. ** HeliDirect is #1 in my book, I thank them for trying out the different products that are out there. Their prices are of the best that I have seen, especially for the Heli that I'm flying and their shipping has been the fastest. Thanks!
