I know it colder but I wonder if the oil was too thin and you were getting chassis slap and the rebound was pushing the nose up. I'm running blue CSI with 55/50 with a big jump and she levels out nicely.

It does fine on smaller jumps like doubles. I mainly notice it when im kind of at mid to high throttle after hitting the jump while in the air. I also tried a j concepts wing over the stock one but had the same result. Its not real bad im just being picky as this is the only flaw I have with the car right now

Its possible that is when you get the most chassis slap. On a bigger jump with more speed. Just throwing some ideas out there.

Im not gonna rule that out as I have seen Gene and guys down south are running heavy oils. I just went lighter cause of the colder weather

My buggy jumps nose down so when I let off the throttle in the air, it drops down and down sides the jumps perfect. But I am using the FTW body also.

We have been playing with the shocks around here and so far the best feel I got out of the car is 1.4 piston with 37.5 oil in the front and VP-Pro dome piston with the dome up in the rear. They are 1.25 hole and I drilled two holes out to 1.3 with 32.5. I'm Running Intech purple springs in the front with Kyosho blue in the rear. I did get the VP-Pro springs to try in the rear but haven't tried them.
I do have some cars around here from RC Driver reviews and got to playing with the Intech with Hyper 17mm shocks. The stock Hyper shocks and springs feel really good on the car. Might play with them for the heck of it.

I did run the Fioroni pistons and they worked great for about 2-weekends and then the rear just let go. Dunno if it was an o-ring issue or what. Just no pack at all. It was slapping and getting the car way out of shape so I said enough of that.

About the warmest temp's I have raced in so far this year is probably in the 50's.

Thats the issue im having as well greg. I can't seem to get the pack. Im running next to no rebound to 1/4 rebound. The warmest I have ran in so far is the mid 50's and since I have been in the A mains we run late when it gets cold. Im just scared to go to far from where im at cause the car is just about perfect everywhere except when its in the air on a big jump.

Yes sir, I don't think I'm gonna find exactly what I'm looking for without mixing and matching and drilling pistons. I think it's about the only way we're going to get these shocks money. I'm wondering at this point if the Convex bladders may have something to do with it. I might grab some Losi bladders and try some things but I'm giving these Hyper shocks a try first.
Dunno why the trouble from a 15mm shock all the sudden. Losi has been 15mm for years and they worked good, just not enough droop.
You for sure have to downside the jumps. Land out in the flat and it gets unsettled quick.

FYI.. The pistons I machined are doing extremely well outdoors. I'm putting in for them to get machined here at work. They are tighter tolerances so there is less blow by. They are thicker than stock for more friction. They are made from Delrin so they will be consistent for the life of the car and more. I have been focusing on rear stability of the car in bumpy situations and I have gotten my car better than my Mugens were in the bumps. I am working on getting my new setup on my website. It's worth trying.

Look for my setup today. I am still testing but I am thinking I've got it! I'm testing again at Hurricane R/C this weekend.

Put me down for a set! (:

Get working on them ben lol.

There will be 3 hole sizes. I am not certain how soon I can get them done. We are busy until June. But, I am trying to get some stuff slipped in to the machine shop.

Get them slipped in. Shucks, shock pistons are important.

The issue to me is minor, but once all of us get it squared away watch out. The car is deadly now. Still amazed with the steering and the rear traction the car has

Tony whats your dirt set up mate? Ran mine out the box at an indoor event on clay, a very small track and manages a 22 and 27 in round from 140 entries.

I am now turning my attention to outdoor dirt for the UK nationals in a couple of weeks, the weather has picked up a bit here and around 50 f last weekend so maybe a similar set up to you guys?

I run mainly astro over here and found 3 3 2 really good in the diffs but looks like you guys run higher on the dirt so will give it a try? Are you running 5 5 4?

Shock wise I have a range of tapered pistons 1.2 1.3 and 1.4 and have purple white and blue intech springs and Kyosho blue and orange.

Any help would be greatly appreciated!

PS bad run last weekend! After running every weekend for 6 months with no breakages I managed to break the front diff housing and lost a pin (massive impact into the pit wall) got shunted in the rear by a flat out car and ripped all the screws out of rear diff housing and chassis brace, lost a screw from the castor block in Saturdays final and popped out the driveshaft and the centre to rear shaft came off in Sundays final probably due to the earlier rear ender! to top it off I had a receiver pack up and a front engine bearing go! Oh well I was due a bad one! Only managed 1 qualifier from 5 on Saturday and 1 from 5 on Sunday, luckily it was FTD timing so made 11th Saturday and 12th Sunday from 50 entries, the car had real pace but just had one of those weekends and didnt finish either final! Must put it right for the Nationals!
