The EXB gears are strong enough for my 4985 motors. If you have a V4 V5 those diffs are pretty tough. Just make sure you shim them good and rock on. Some other guys might have some better options but I have always just kept a check on everything being tight and without slop. When the cup outside the diff. where the shaft comes in will wiggle either change bearings or retighten it. I suggest ceramic bearings in the diff housing and aluminum housings too. The aluminum diff housing cover by itself adds strength IMO.yes the 4985 .. it's weird size not much out there for heatsinks
There's no way the stock differential gears are going to hold up with all this power..
Are there any super strong gears out there for the kraton 6s's gears?
I’ve read that since hobby wing motor already has ribs on it, it doesn’t really benefit from having a heat sink.hey guy's. Any recommendations for a heatsink that will fit the max6 motor?
