I've liked the FTW/Snow's Design Diamondback body.

Do they have the Raptor clear pre-cut?

proline flotek fusion

Interesting that you said that about the JC Illuzion HF, we just started running that body and love it. We're not cutting it out at all and have run it indoor and outdoor. I'll have to pick up the Raptor one you mentioned and give that a try to compare.
The only body I wouldn't run is the EVO. It's really designed for 2wd and works great for that but on a 4wd it's way to much front downforce.

Matt, interesting you say that. I just started running the fusion body, and it's in air characteristics aren't very flattering. I was debating rattle canning the illusion f250 body and seeing if it acted better.

Default Traction Role

Our indoor track was rebuilt 2 or 3 weeks ago and seems to have more traction more consistently than it use to. They are keeping it more moist. I've been fighting traction roll entering the turns off throttle for a while. I've changed stuff and changed it back with limited success. I looked back thru my race notes at my changes over the past few weeks to see when it started and what I had done. My notes looks like it may have started after going to a softer rear spring Y to G. But the other day I went G to P in rear and it seemed better until next race day. Then it was back to rolling. Another time, I raised droop and it worked decent until next time racing. Then it was back again. I looked again last night at my notes. Only thing that I haven't changed back that I did during that period was going from 7 10 5 diffs to 10 10 5?? Not sure if the thicker front diff oil would cause it? Any input would be appreciated and I've attached my set-up sheet.

assuming the tires are still the choice to use, maybe try this:

- next level up sway bars all around
- raise up camber link on rear tower 1 position
- limit rear droop more
- lower ride height
- less rear toe

Here on high traction carpet we fight the traction roll issue. Guys have different takes on there setups, one runs pretty light diffs, other heavier. other items though look very similar.

I would say though that if your traction has come up even more, maybe the tires are not the hot ticket as they are. Maybe try a set that is more worn so you get a bit more drift.


Something came in the mail today, excited to see what it is when I get home from work

I'd agree with everything Cain said minus the going up on the rear camber link. If you're traction rolling into a turn off power the first thing I would do is go to a higher rear roll center. You already have the rear at the highest roll center position so you'll have to do some other things. Lowering the ride height is the biggest thing I see. I run 19mm front and rear with the body mounted at SDRC (high traction indoor clay track) so 24mm would be monster trucking for me . Also 4 degrees of toe is a lot. I usually run 2.5 or 3 degrees everywhere I go. Another thing is you have a very high roll center in the front which can make the truck feel hard to control under braking or off power. I would definitely go up on the tower in the front to the middle hole, if not all the way to the top. Another thing, if you don't already have them I would pick up the HRC rear hubs for the SC, should help since you're already at the max for rear roll center this will get you a little more. I would go down in the front sway as 2.6mm is thicker than we normally run. When you start running a sway bar that's too thick it causes handling inconsistencies as it's overpowering the springs. Go up in the rear after you've felt the change that going down in the front made. Also put the center and rear braces back on, you might have too much chassis flex adding too much rear traction as well.

The Pro-Line Flo-Tek Fusion? I haven't run it but there's a guy that we race with that does and he really likes it.
I ran the Illuzion F-250 body a couple of times but I was testing some stuff on the truck that didn't work that well so I have an unfair bad association with it, lol. I want to give it another chance because it has the built in wing in the back but I haven't had the time to get another one and my current one works so well.

Interesting...I hated the jcon raptor. It didn't handle for me and make the truck a lot more difficult to drv. It was just too loose especially in turns. I was alternating between it and a jcon titan and liked the titan a lot more. I need 2 put some more time in on the 250. So far I'm not feeling it too much, but a lot of people like them. I haven't tried my jcon h2f yet. I really like the way my fusion handles (turns & jumps). I liked the evo too. So far the fusion is the body I like best. Would like the try it vs the titan and fusion side by side as there was prob at least a yr between me owning the two.

I'm going to try a 3400kv hobbywing on 2S, has anyone run this and if so do you remember what pinion gear you were running? thank you in advance, I've tried searching but can only find a few that ran it but no specifics.

Thanks guys. I will look into these suggestions next time at the track (Tuesday). 24 on the ride height was just the last setting I tried. I tried 23 too I think. If I remember right, I couldn't get the front much lower than that for some reason

Question, on both the c and d blocks, the setup is on the bottom holes. Can't you move those up to raise the roll center to get a little more? Which adjustment affects roll center more, the shock towers or the blocks?
