Why not just get the promatch 3500. Between your 4800 and that one, it is 60 grams right there.

my only concern is the occasional 10 minute main that I make. Granted I dont make it weekly, lol. But even with the 4800 in my lighter rm b5, some jumps became much harder late in the race. In those races I used over 2000mah, which would put the 3500 pretty low voltage

Here it is on the scale right after I finished building it.

At least 8 grams too heavy

lol, wtf is that sound? check your mesh and pull the pinion off and make sure it spins freely. Also, make sure your pinion is not rubbing the gear case

Ugh, i dunno. Took everything apart. Everything moves perfectly freely. I think the motor is a bit loud when its at the very low end, makes a loudish clicking noise when spinning the rotor, seems normal.

Otherwise I can't pinpoint any issues at all, mesh seems totally fine, I can move the spur teeth without moving the pinion, but barely. When I run it on the ground it sounds fine. I may just be over reacting.

I dunno. My motors dont make that sound, lol. But if you can do the 2-3 inch lift without barking and everything is free. then leave it. I would watch temps. Maybe even oil the bearings.

When you turn just your pinion do you get about three positive stops or does it turn freely?

oooooookkkkkkk. So the lift test failed. Time to rip apart the tranny. This is my diff. I rebuilt it last week. What happened? Im sure it was too loose, did I destroy the balls? If it was too loose could the black grease from the thrust bearings work its way into the center of the diff? Should I clean and rebuild or just buy new stuff

Thanks for your help everyone!!

that is the clear grease burned up from heat and friction. you can probably flip the rings. but I would replace the gear and the diff balls (the thrust is probably fine). if the balls in the gear get to hot, then can become loose in the holes and move around on you. if you had enough heat to burn up the clear grease, I would just replace.

Damn. Looks like you used black grease for the diff balls! Never seen a diff black like that. If you get any black grease on the diff balls it will slip. Very little black grease needs to be used on the thrust.

Bummer.

Would that be caused by it being too loose? Thought I was getting the hang of this stuff .

I may just rebuild it until I get back to the shop. Bad idea?
