I've got the Revo's axles but the "u-joints" are to big for the stock pede parts. I don't want to dremel out the metal drive yolks or metal stub axle as I feel that would make a new weak points. Does anyone know if the Revo's Yolks will work on the pede tranny/stub axle carrier? I've broken many pede axles.(plastic yolk on the axle snaps and/or slider wears out, mostly broken yolks) I have the FLM Ext.Arms so I'd also like a little longer axle for more contact between the sliders. If anyone has any ideas, please let me know. By the way, the Mamba 5700 is the motor of choice and is VERY HARD on the drivetrain.
