It's because of the bad movie quality, and that's why I noted in my post that the gears didn't 'skip' - maybe that's not the right word for it. :)</p> <p>Anyway, tend2it posted an answer, and it appears that some motors just have this 'ratcheting', and in his case it didn't make a difference in performance. Maybe I'll try to replace them and see if I get better battery/flight performance. Thanks.</p> <p>-Christian</p> <p>Hi Mike, I know it looks like the gears are slipping in the movie, but actually they don’t.

It appears that the motor gear seems quite worn. The gear teeth almost seem to be 'cupped out' in the area where contact with the white gear is made. As you rotated the propeller, the slippage wasn't at every tooth, but at most of them - I could see the teeth slip back sometimes, rather than rotate. In addition maybe the white gear is worn. The gap between the two gears is too big. Good luck, Mike </p> Hi Christian, I just saw your ‘ratcheting propeller’ movie on forum.xufo.net [corrected link]; it appears to me that if you play the 2nd movie in slow motion you will see that the ratcheting sound seems to come from slippage between the pom gear and the pinion gear.
