Brushless Kyosho S-RR

[Shark413]

Well no more machining for a while, my bad machining skills blew the gear box in my mini mill. But I was able to finish the spacers the old fashion way, saw, dremel and files.


Broken gear - Mini Mill


Carbon Fiber spacer for front diff support


Aluminum spacer for diff/motor mount.

hi shark413,im the guy who got your old cen conversion.im having so much fun with it with the MMM.only problem is i keep stripping spur gears.i stripped 3 already and and im not even doing any jumping.i got a steel spur gear but im reluctant to try it coz i might melt my pinions or something else.can u give any advice?id appreciate it.thanks

cornolio, glad to hear from you. I also had issues with stripping the plastic Kyosho spur gears, so I swithced to steel spur and a hardened pinion. I have been running these on all my brushless conversions with no problems. The important thing is you must use a Mod 1 hardened pinion, which RC-Monster, Impaktrc, MegaUSA all sell. I am also using a wide Robinson Racing Losi spur gear that is wider than normal and spreads the contact area out more, which improves wear on the spur and pinion as well.

Spur comes in 47, 48 and 49T.

thanks shark.sorry for hijacking your thread

cornolio, no problem. Just to clarify, if you switch to a steel spur the hardened pinion is a must. The wide Robinson Racing steel spur is optional and a nice to have but not a requirement.
