I did not need any shims with mine. You want just a tiny bit of slack between the hex and hub when the hex is pushed on all the way. For me, and shim made it a tight fit with 0 slack.

Looking for some setup help. Last couple weeks I have been struggling with a few things, listed in order of which I believe is slowing me down the most:

1. Bottoming out and nose sticking in ground on some jumps
2. Rear grip on power
3. Lack of steering in tight turns, mostly off power

Here is my setup: Justin SCT410 setup

Below is a video where you can see how the truck is behaving, and I talk about the issues as well. Any input? I was thinking of changing rear diff fluid back to 3k, adding back a couple mm of droop, maybe increase my front kickup/caster back to bottom hole, also do battery mod to move battery back. Open to other suggestions, been trying to get the truck really hooked up for the past few weeks..

+ YouTube Video

Will the cnc eb48 shock towers will fit on the sct410 ?

Before changing fluids, try some of these easy changes first.
-Shorten your wheelbase all the way, that should help with off power steering into a turn and on power out of a turn.
-Move your Ackermann to the rear hole. Helps with turn in, increases low speed steering on and off power (less scrub) and will decrease your high speed steering which can make it feel like you have more rear grip.
-Try raising your rear roll center by running #3 on the rear inner camber link location. The increased camber gain during compression will help your car center and square up on acceleration.
-Move your anti-squat to the middle location. Your track might be low enough traction that the rear end isn't using the suspension to create enough mechanical grip when you get on the throttle.

Yes, they are a direct fit. ;)

Latest upgrade to the tekno. well its what the competition sees J/K :cool:

Updated first post to include Losi, Hot Bodies, and Kyosho spring information.

Regarding springs, I've run yellow tekno springs in the rear for a while on all of my setups (taken from my EB48 when I put the Kyosho Oranges on the back of it). On the front I've run Tekno Black (Way too soft except with stock pink rear), Kyosho Orange, and Tekno Yellow (another grab from the buggy). On high traction sugared packed outdoor dirt, both of the options work well. On medium traction packed damp dirt indoors the Kyosho Orange was much better all around, as the yellow tekno front pushed a bit more than I like. I've put the yellows back on the front and given the truck to my wife for driving, as she's coming from a pushy Losi and it'll be easier for her to drive and get back into (novice level driver). I'm definitely sticking with the Orange fronts on my new one, and the Tekno Yellows in the rear seem pretty good all around too.

If I were on something very blown out, or on something really loose, I'd probably want to go back to softer springs, but for high traction and for indoors, I like the stiffer springs. Stock 10x1.2 pistons all around, running 450 in front and 425 in rear for oil.

Great, thanks for the feedback! I will try some of those changes for next weeks race and see how it goes.

I just got a set of mud guards for the rear arms today, after putting them on they rub my wheels. has anyone else had trouble with them?

I'm just going to trim them down with my dremel, but thought I'd see if anyone else was in the same boat

Yup same boat. Dremel time.

What weight oil is a good starting point with 1.3-8 hole pistons front and rear.

I'm running 30f 25r losi oil with stock springs outdoor feels pretty good. Might need to go up a little with the warmer weather. I ran it last weekend with pink fronts and green rear springs but it felt a little over sprung. So I went back to the stock springs.

I know u are asking for a setup on the 8 hole 1.3. But if you can try Matt Wolter setup on the website. My car has never felt better.

nose down off jumps, i would def do the battery mod, stiffer springs and some stiffer oil (if you continue to run stock pistons). i know some ppl have not had the issue, but if you do or have like i did you know it sucks. the battery mod with stock pistons and pink front and orange rear with 50fr 40rr was the only thing that 95% eliminated it for me. the fioronis with the battery mod has totally eliminated it and feels great. the nose down is due to the car bucking at the jump and IMO because the springs in the rear are to soft and not rebounding fast enough, letting the rear slap and buck up before the springs have time to react, the thicker oil will also slow down the initial compression when hitting the jump not letting it slap and buck so hard.

full anti squat, for me i kept it in because i come out of turn hard and seems to keep me planted. i have tried middle hole but felt looser to me. this is just personal preference, i know and heard some people say taking the anti squat out has taken the looseness away but for me its the opposite. i feel i can drive it harder with it full

inner hinge pin, i was doing some testing with the shocks and oils a couple months ago and trying to get a lil more roll. a good friend who is the track director/owner of the r/c factory who has also been building the tracks for the midwest electric championships for the past, O i dont know how many years, and been racing for 20+ years noticed my hinge pin placement and suggested i move it to the inside to change the pivot point and i will get more roll. so i did and never looked back, i noticed it would rotate a bit more cornering.

inner upper link, i was originally running it at the lowest link so it will react faster but noticed it would break loose easily, i moved it back up to the stock position so if it broke loose it was in a very controllable way. i have liked it very much

lowering the shock on tower, i was playing with some settings, first went all the way down on tower but it made it to twitchy, i was trying to get a lil more responsiveness and went back to only one hole in from stock on tower and liked it.

do i think these will solve the looseness.....idk because i'm not sure what your current set-up is as of now, so hard to say. i can tell you my truck feels planted

the biggest things i have done that i feel has made my car feel hooked up is the fioroni pistons, battery mod, red rear spring, and 10/10/5 diffs.................hope this helps. i'm not the best explainer nor as knowledgable with some of the tuning explanations as some of our fellow racers on here. and i tend to ramble.......hahahahahaha
