ARRMA Metal Gear F/R Transmission Module Set, ARA311156

work well right fit

Love It.It Is Not Loud And is Good Quality.

These have been pretty good so far, the only reason I dropped it down to three stars is because the price keeps going up. You used to be able to get these for around 50 bucks. ARRMA should have never put plastic gears in their 3S cars so eventually you're going to have to buy these if you're still running plastic. However, I've ran these metal gears in the rear for a couple months now, running it every other day, and it has held up good so far. I'll be buying a metal front diff from somewhere else due to the price jump. The only good thing is that once you do have these upgrades you can get replacement ring and pinion gears for around 30 bucks.

Not once, but twice I've ate the teeth off the ring gear! 2 different diffs! Nooo not a 120c lipo.. just a good ole trusty 50c 3s ovonic. the second time I didn't even make it through a back flip before rear diff was gone, again! arrma won't respond to my emails either do yourself a favor and buy a rcawd diff you will thank me later. Or do what I've done and hung up my arrmas and picked me up a redcat valkyrie mt10! comes 4s for the same price as arrma 3s line bigger, better, faster, and tougher and customer service is out of this world dude! they are unbelievable, and want to know anything you can tell them to help them improve! will absolutely help you through any issue you have I probably won't look back

This broke 2 days after installing it. Not very sturdy at all!
