Finally after trying and trying I was able to find the CORRECT setup sheet from Scott Hughes Silver State win "this year"!! I was first sent some sheet by a guy who I think just sent me his own sheet?? Then I was given a link to a sheet that ended up being Scott's 04' SS setup?? I put the setup to the test over the weekend at our local track in Lexington Kentucky www.coyotehobbies.com and I was able to take the A-MAIN victory with my MBX5 Prospec in a Kyosho SP2 "FILLED" race!!! BY 3 LAPS!!!! Honestly go check the results!! I now have a set of JLB shocks on the way for my Mugen, to run this weekend at the first round of the Midwest Pro Series in St.Louis. Later "RCTechers"-RYAN

How did the car feel, Ryan? Was there anything it didn't do well?

Honestly the buggy was very aggressive, yet very driveable. It was handling this triple, double, double rythem section very well that alot of the other buggies were just absolutely fighting to get through! It could have used a bit more steering entering corners, but was awesome coming out. This was also due in fact that it started to lightly rain at the start of the 15 min A-Main, and corners got real slick! But I was still able to clear this large table top that was just out of a turn fairly easy, and alot of others were fighting traction issues to get a run at it. The "ONLY" part of Scott Hughes setup that I didn't try, was moving my tie rods to the rear of the ackerman arm, (I kept mine in the center) and I intend on testing this because it says that it makes the car alot more responsive going into corners, but less forgiving? Meaning it will react quicker, but if you oversteer it will be harder to save it coming out of the turn.

Default Ryan, Its not like you need it to win.

Ryan,
I Copied the Hughes 2006 SS MBX5 set-up before it disappeared.
Here is a compare of 2006 and 2004:

For the bumpy 2006 track, looks like Scott went lighter on the shock oil, Stood-up his shocks more and dialed in more camber. Also, no front toe-out and a smoother rear diff problably helped too.

Two unique things I see in that setup other than the very soft oils:
1. 1* anti squat. most MBX5 guys run 2* (me included)
2. The upper insert front and lower holder for the upper a arm hingepin. 1st time I've heard of that.

It's also kind of weird that the track was super rough and he still ran the lower rear shock mount on the outside hole in the a arm. Using the inner hole on the arm makes a profound difference in the rough.

DavidKa,

I run on the same track that Ryan Barnes races on. Great eyes on noticing the outer shock mounts on the arms. I cause the buggy to get very upset with the arms on the outside.

Barnes you really need to move the rear shocks on the inside hole on the arms. I have not yet drove Barnes setup but the Jason Ashton setup works very well. It may not be as forgiving but forgiving is not the fastest setup in my opinion.

Yeah I was looking at trying that (inner holes) this weekend in St.Louis, because with all the traffic, the track will get really dry and super rough. Plus I like the Hughes setup because it's the most current and very proven, he's won the last 2 major events, Silver State and the RCX show with this setup.

The only down side I have found with the inner holes is with all that down travel the rear can get loose on the brakes pretty easy if traction is low. It is easy to solve with the droop screws. I really think the advantage to that position is more about leverage against the shock than the down travel that you gain. I practically aim for the rough line off of turns it works so good.

Good idea using the droop screws.

Barnes,
I will have to try that setup sometime.

I take the droop screws completely out of my arms, they only dig grooves into your chassis, and put added pressure on everything. I set my droop internally, under the pistons, using rubber o-rings or the small plastic washers. It all just depends on how much droop is needed. Plus the washers or o-rings will relieve the pressure from the pistons at full down travel.

Barnes,

Good luck at the Pro Series race!


Rear outdrive play:
I rebuilt the rear diff. and noticed the rear outdrives has play before I mounted the diff in the buggy. Is this normal for the movement?

Ryan, I didn't have the droop screws in my car until this season either. It is really nice to have the tuning option track sied instead of taking apart the shocks. I have also been told that the droop screws help protect the shock ends, the caps (they ovalize) and the shafts. I still run full droop most of the time anyway.

A tiny bit is fine. If it feels sloppy then you may have left out the diff gear shims or need to add some. Each internal gear is backed with a thin shim and they can be added to remove excess slop and tighten gear mesh. Also check that your cross pins are intact.

I think i need to add a shim behind the outdrive because it seems to have to much forward and backward motion. Which is causing the bevel gears to move back and forth. The cross gears all have the shims behind them. That could be the reason why my diffs are leaking as well.
