Hi guys, is there a metal idler available? Do the stock idler and diff gear hold up to 2S lipo and a Castle 5700kv pretty well? Thanks

I dont know about the castle system but I ran a 4.5 novak in my t4 with no trouble and truck ran great hard to drive but thats a big motor

It will hold up well if you set our slipper correctly

I know that they sold a steel idler gear for the GT. Not sure if it's compatible with the electric versions, but might be worth checking.
