Did you have to do any grinding on the chassis or the belt guard on the belt pulley. Looks close to the bearing blocks. But all it has to do is clear. Thank you

I had to grind the chassis just a little to clear the diff.

The picture of the standard photon; diff needs to move over a tad bit to the right but I never got around to doing shimming since the car just sits. I didn't grind either car but it seems other people have.

After racing my cars this last Friday night I found my problem. Never seen a ball diff hang like mine did. Both cars did it. So I order the diffs from a-main, today along with shims. The set up that I was given here a few pages back really did the trick Just a little loose at the rear. I have already order the coils from rc mart. I'm going to take and re-do the oil in the shocks just to be sure.

- on rear outer camber link holes inside and outside. 1mm spacer inside 3mm outside.
- rear camber 2 deg
- 1.5 front with 6 deg caster block (2.0 deg with 4 deg caster block)
- 1.2 mm sway bar front and rear

This works well with ride 32 red on low grip tracks.
36 compound for higher grip

Hope that helps

The alloy one piece seemed far more consistent for me

Hey guys. Lots going on here since my last visit.

Let's see. Diffs - I've been interchanging my gear diff between my photon and my EX. No issues there.. Only thing is that you need to play around with the spacers to position it right. I don't however like the fact that the TOP diffs leak and the out drives are fragile. I suspect the Yoks are better.

I also use the one piece servo mount on my EX. It's nice. Cut off the little nub on the chassis so it doesn't hang up when the chassis rolls.

Springs - I use the the soft gamma springs. 274 and 260. Works well on low grip tracks here in Malaysia. Funnily enough I think the EX works better with softer springs. The old Photon just needs harder ones. Maybe this is just chassis flex-related. The old Photon is as rigid as my... Well... It's pretty rigid.

Well I fill plenty fullish after saying it didn't work. It works just find my blind eyes aren't helping me at all. The diff from the EX will fit the standard Photon. After everyone saying they work. I had to try again. It does work and you have to shim it a lot. I'm sorry if I cause any grief. Some how when I drop the diff in I'm not sure what bone head move I did.

Yogii, glad it works fine now. It should. Just beware that the out drives are quite soft. Change the blades often and clean the out drives after every other run and they'll last. Problem is dirt getting stuck in them (since the diff leaks) and that'll just wear them down.

Does anyone have better experiences with the Yok? I tried to fit ARC out drives but they are a tad shorter and the only way to make them fit is to remove 0.5mm of plastic from the outside of the diff housing. But unless you get a perfect cut the diff feels a little lumpy.

Guess it's Yok for me then. Do the TOP blades work ok with the Yok or do. Need to get the white ones?
