I found an aktionRC sleeper480 kit on ebay, and a couple 480BB 7.2 motors, so I'll need some pinions!
I understand the shaft is the same diameter as 540 motors, but how do I know if a pinion is designed for 540 motors or not? I've found some 24t pinions on ebay, and even towerhobbies.com, but neither place lists the shaft diameter. Using the search function on this forum, I've found 22-24 to be the recommended pinion for the 480 motors. Any places you would recommend for pinions, w/ reasonable shipping?
Also, my LRP doesn't do more than 6 cells/7.2 volt. Is it worth it to run 9 cells on the sleeper? Any ESC recommendations? Is motor life affected in any way with 9 cells, versus 6? Keep in mind, I don't race, I just run this sucker in a parking lot.
BTW, here's a pinion on towerhobbies, would this work. It's just a shame I'll have to spend more on shipping than the pinion itself.
