48t spur or something else? I have the 50, is that what the 18 is supposed to pair with?

If you have a 50T spur and a 2000kV 4S setup, you can try the 18T pinion, but the optimal will probably be around 16T or 17T (depends on the track, driving style and conditions). Check the temperatures!

I'd go 16/48 or 17/50 forget the 18.

Great thanks. Built with the 50 last night, will get a 17 pinion ordered.

I found the aluminum front hubs in my box 'o' spares but I do not have the hats. Any idea of those are available separately? Also I see the setup lists the V2 rear hubs. How are those differentiated? I know the 2.0 have the mud scrapers, but not sure betwen the V1 and v2.

Thanks!

Actually the buggy rear hubs you need are the 1.0 v2 hubs. Part # 600476.

What shims are you guys using for the front diff? Are you using shims inside or outside the outdrives/bearings or both?

When I bolt the front diff case down, the diff is totally unmoveable and completely locked. I'm converting my nitro truggy, which has over a gallon on the diffs.

I know what "tight" and "notchy" feels like, and I have the eBuggy as well, and this aint it... the front was really smooth before, but after flipping the diff, it wont budge at all.

I've tried a new diff case, and up to 2 shims on the outside of the bearing opposite the crown gear to push it away from the pinion gear, but I'm not sure what else to try...

my rear diff is perfect, with 1 shim opposite the crown gear, outside the bearing.

I personally don't use any shims between the diff itself and the bearings. I just use the large shims on the outside of the bearings between the bearing and diff case. I always used two shims between the pinion and bearing, and then use the large shims outside to get my mesh correct. I make sure its slightly notchy with NO PLAY. Also check to make sure you aren't hitting one of the three screws that hold the pinion assembly together. There has been times were the diff will hit those and be VERY tight.

So interesting that you bring this up.

I had a lot of play with the bearings on the diffs, and initially shimmed between the diff case and the bearing. It would not even fit in the diff case (had 4 0.2 shims on each side, there was that much play). I ended up flipping them to between the bearing and the outdrive, and they spin fine front and rear, but the rear mesh seems to be off as I burned up a new 43t diff gear in less then 5 min of running. Shims are stock from the V1 setup (3 bearing). I have a new gear coming and some shims to see if I can get it a bit better.

How do you set the mesh between the pinion and diff gear in the front and rear diffs? Purely feel?

Never had this on any of the buggies so a bit surprised.

Oh, the truggy was also awesome in practice. Almost the same as the setup Chicky posted, minus adjusting for V1 diffs (7/10/5). Truggy turns amazing and flies great. Very impressed. First actual race with it should be next weekend, preparing for AMS.

Thanks for the updates on the shims, nice to hear everyone else's struggles with this...

I'll have to check the shims between the pinion and the bearing, however, that would push the pinion "closer" to the crown gear, thus cause more binding... right? If I already have shims there, I might remove one and then see if that also helps free up the diff. again, since I already have over a gallon on these diffs and pinions, I'm not expecting them to need to be run-in further... all I"m doing is flipping the diff for electric conversion...

also good point about the philips screw holding the pinion bearing in place. this has not been an issue for me in my buggy, but I'll remove it or move it to another spot, and see if the diff is more free.

Currently I only have 1 philips screw holding the bearing inside the diff case.

My eTruggy conversion is complete. Purchased a new Nitro Kit and eConverison. Truck arrived Monday evening and last night the build was complete. This is my first Serpent. Build was straight forward and went together really well. I am impressed by the quality of the plastics. I will say I did not use any shims between the crown gears and diff pinion. They are tight. Will run it @ AMS to break it in and then check the mesh. Will post up some pics when the body is all mounted up.
