It doesn't have to be level.

Are we all talking about the same thing, the new Tekno aluminum servo horn? the link mounts above the horn and I did not have to shim anything. you can read about it here:

I don't think you have to shim anything either but the link does mount above the arm. The horn lowers the mounting point closer to the servo housing. I could take a photo later if necessary.

Yes sorry, I am mixing my words, the link does mount on top of the arm but you do not need shims.

Well after selling all of my rigs and taking a year off from the hobby, I placed an order for the SCT410. It'll be powered by a Pro4 HD 4300 and a RX8 Gen 2. This will be my first kit build. Any tips to make the build go smooth? I'm so stoked to get back in the game!

this build is smooth and easy, I got some MIP thorp drivers which made it easier, check first page

would also recommend NOT using a ball driver on the mount mount screws so you can torque them down without stripping.

@Slotmachine.. when you say thicker fluid in the rear will cause no steering ability what's too thick? I'm currently running 7/7/5 so will this mean that as I enter turns I will consistently spin out?

Hey guys, just ran my sct410 for the first time yesterday and really liked it. I already put aluminum hexes on it plus an aluminum rear toe block. I am doing a battery tray mod tonight and want to know if there are any other necessary/relavent mods that need to be done. And yes I have read through the thread for hours.....

Also I was running very hot on the esc (it thermaled) but the motor was perfect. I run an Orion r10 pro 160A esc with the hobbywing 3656 4700kv motor with a 14t pinion. I assumed this esc would work well being a 160A. Was I wrong? Was I under geared?

I haven't had a 2wd slash in yrs and it was all but stock too.. No matter what you did the thing was still junk for racing. I run a SC10 in two wheel drive now a days..
I like being able to move the battery a bit to help with tuning so I'll see how it goes once I run this thing. Still have to pick a motor and servo for it and wait for the weather to cool down

Could use some setup ideas for ROAR Regional at "the biggest track in North America" aka Thornhill in Hutto, Texas. The track is ginormous. I've been once, and struggled with only a couple of hours to practice. I remember it's big and fast. Traction is pretty good. Can get a little dusty on top. A good size triple; big table top, signature "The Dirt" step up with brickyard run up. There are a number of turns where I feel some drifting would help... my truck turns; it doesn't drift ;-). My local track just changed layouts. It's tight, bumpy and dusty... Both cars seem ass happy... so I don't feel like I'm starting with a good tune anyway. Taking both SCT410 and EB48.

I think I'm hoping for insight on roll center, shock position, etc., but I have plenty of pistons, springs and oils as well.

SCT410 has as of today...
Motor/ESC - HW SCT-Pro+4k(16t)
Shocks - RCShox dual-stage - Front/Green/425 Rear/Orange/375
Diffs - 7f/10c/3r <-- down from 5r looking for better high speed cornering
Options - 17mm hexes, lightened outdrives, chassis, shock towers, new rear diff and straight gears

EB48
Motor/ESC - Tekin RX8+2050(17t)
Shocks - Tekno 10x1.1 - Front/Yellow/425 Rear/Red/325
Diffs - 7f/10c/5r

Hope this is enough detail to solicit some ideas. Thanks.

Do you have the 4-pole firmware?

14t is too small and usually a motor that's cool and ESC hot is an indicator that your under geared. I have that same motor and used the biggest pinion from my Mugen... 15t and it was too small even for an indoor track. I would say try a 16t and see how it goes.

Thanx for the tips Cain & Slotmachine. I will try both directions.
Makes sense for thicker fluid though as tightening a ball diff will calm down the rear end entering a turn.

Usually when you are under geared the motor runs hot and the ESC runs cool.

14T seems about right to me. I run a 16T on a large outdoor track with the 4000kv motor and have plenty of top end. 14T on the 4700 would be about the same top end.
