+1 Great advise.

I'd say 6.5 is a good all around motor. When on a small track I just turn the radio down to 75% throttle. No use getting a 13.5 then realizing it's not enough for your track. These are 4 wheelers, they like lotsa power

I'm sure the Exotek is a good upgrade but make sure you have a good look and make sure there isn't a reason the original one stripped in the first place. I've had mine a few months and the stock spur is still fine. I think with all the talk about the stock ones being a little out of round, some are leaving the mesh a little looser than it should be.

Anyone have issue with the center diff leaking? Those super small screws are not very good I don't think strip the diff case easy if over tightened.

Make sure and take your time using the right tool. Did you use a .050 or the 1.3mm driver? .050 fits a lot tighter. And when you tighten them down do it like a car tire, don't cinch them down in a circle, go in a star pattern. Make sure you don't over tighten them.

I did.over tightened too so I replaced with new stock one and ordered spare, then next day exotek comes out with there's that solves the problem. The stock replacement seem to be little harder plastic and no leaking since.

I did use the right hex and a star pattern. I just think the screws should be a bit bigger thread size. I bought this used was leaking a bit I changed gasket and oring but when put back together leaks worse. Two of the screws didn't tighten up all that great.

Mine has also been leaking. I assembled with much care abd the second time I put gasket sealer, haven't ran it yet.

Overfilling maybe?
Fill to top of cross pins then install final sun gear and spur/cover.

Iím looking to get back into buggies and was wondering if a 3800kv Neu-Castle motor would be a good entry point for me with this kit. I havenít raced since the late 80s (RC10 for 2wd and Kyosho Optima Mid for 4wd).

I have pretty much decided on the D413. Has the parts supply improved much? I see Amain and Tower carry parts. Are there any other US online stores that are trust worthy as well?

while that is a good motor, I think you'd be much happier with a sensored system

Glad I asked. I'm familiar with sensorless ESCs and motors from racing fast electric boats, but didn't realize the cars benefited from sensored power systems. What would be a compatible sensoed setup in the 3800 kv range?

Thanks

I found the problem with why i stripped the original, it was due to my motor coming loose, i think I've over tightened the motor mount and may have stripped it cause it just won't tighten up, just as it starts to get tight it gets to that point and then just spins and becomes loose.
