I agree, but I haven't found any that would work. I tried ordering pinions from Tower already. I found some that looked close and they were, but not close enough. Somebody posted that the gears are some kind of weird pitch like 55 or something. So far I've seen lots of suggestions, but I haven't found any post saying they found one that worked. I saw a video of a guy doing a BL main motor install and he used a E-Flite 370 4100Kv motor. He used the 10T that came with the motor. He said he also got a had a 12 tooth (I think it was 12?) with the motor, but it didn't mesh smoothly/properly. That comment alone makes wonder how well the 10T really worked. So with all that I ordered another motor. The one I ordered was only $15 so replacing it is no big deal. The [link=https://www.unitedhobbies.com/UNITEDHOBBIES/store/comersus_viewItem.asp?idProduct=4875]Feigao[/link] looks like it should work pretty good. A machinest once said to me that if it only takes two tries to get it right your doing pretty good. So we'll see. I probably just jinxed myself, but I'm keeping my fingers crossed.
