| opinions on full metal trans or just idler?
Stripped a idler gear. My own fault, 4s, 21.5 brushless with timing advance. My question is, is the diff gear big enough to keep plastic, or is it just a matter of time. Anyone have any experience abusing the plastic diff gear with a metal idler?

When I stripped my idler I went full metal, go in once and forget it. That was my thought anyway. |

With that kind of power the plastic gears are gonna be trouble! Like said, go metal and find another weak spot. |

The stock gears lasted a couple packs, started doing forward flips in the grass and it finally let go. The teeth where still complete, just sitting in the input gear and a bald spot on the idler. Having fair luck with Losi cvd drivelines from a comp crawler, just wish they had a bit more working angle. |

I'd replace it all, the tranny outputs have a short lifespan also. With that much power I'd get a metal case too.

I striped the big gear first-installed metal gear-then the idler gear stripped-installed metal gear. I used Robinson Racing gears.

Stripped the idler gear, installed Robinson Racing gears idler and diff. Twisted both drive shafts, waiting on MIP CVDs. |

My order was installed MIP's, broke tranny output, noticed gears were wearing bad and ordered metal gears, locker and case, broke outputs again before parts came in. Wheel hexes were the next weak spot then went VP,then went through front axles like a fat kid goes threw candy, then installed 300's and never broke again, although the R&P's started showing serious wear in the front, so HD's were installed with UD's in the rear. Still run stock spur, did rip, bend, break some servohorns after the 300's, Robotronics fixed that. Gotta love the combo of 8711 and brushless power.
