The only issue I'm having is: on the gear diff, when I put the bearings on the diff halfs they go on pretty tight and when I put it in the car it doesn't rotate free its bound up. Any suggestions on how too correct it?
also what size sway bars come in the kit? The instructions insinuate they are 1.4, but mine only have 2 little markings on them, typically indicating it is a 1.2. Not sure how serpent labels theirs, but Xray labels theirs by how many little painted/etched markings are in them. Just wanted to make sure because in the building tips it says to use one size bigger sway bar insert. I didn't want to use the wrong one.

The kit sway bars are 1.4mm (2 lines).

I recommend buying the gear diff revision kit to make a gear diff with 4 gears instead of the kit 2. I find it better simulates a ball diff feel both by hand and on the track. I like 1500 oil for mod but lighter works well in spec.

I guess we will see if I did the right thing when I run it.
Does anyone know if they make plastic replacement gears, or a diff with 4 satellite gears?
I would put the shims and oil..then break in with the drill motor... So far my diff very smooth....with 3000 wt oil...

I would think 4 spider gears for mod make sense...two for stock spec..

You will find everything you need to rebuild your shock in the manual.
I don't have "excessive" play on the steering, you just have to tight the screws. A little play on the bearing is perfectly normal.

I'm having a problem with my bearings fitting too tight on the gear diff halfs causing it bind and not rotate smoothly. Has anyone else ran into this? Im not quite sure what to do. I was thinking about grinding some material of the diff half. Any suggestions?

Actually its got nothing to do.with the load on the diff. With 4 bevels the diff tightens up as it spins up, with 2 it does seem to change at all and you get no drive without heavy oils that reduce rotation.

ACTUALLY with 4 spiders gear is better than two...
We are saying the same thing...
btw I didn't mention anything about the load on the diff...

Yes, there is a diff revision or (rebuild) kit that comes with new gears. Diff feels way better than the TOP, or the spec-r gear diffs. I ordered another diff to try in front. http://rcmarket.com.hk/product_info....ducts_id=11460

Great build; finished up a day or so ago and no hiccups. Great job Serpent Now to go shake it out on the track

Btw....when comparing the main chassis to my TC6, is was about 8mm shorter. Anyone else do any comparisons in that dept.?

Is that a team powers plutonium motor? If so, how do you like it?
