Has anyone tried using the VTD top deck and 2.25mm carbon chassis on low to med grip asphalt? Or would this combination have too much flex to have any benefit on asphalt?

I ran it for 1/2 of the 2016 asphalt nationals event in mod TC. I liked it and will have vtd on my A800X car to start with outdoors

I dont have an A800X. These are A800s.


This was the A800 + VTD, modified TC, on a low bite, cold and a slimy track. Took a couple laps for the car to come in. You can see the difference compared to the other cars.

Dazzk we run on very low grip grey ozite and to help reduce on power steering you could try a few things, such as toe out in the front, go lighter diff oil in the rear, run soffter rear setup to allow the rear to squat under acceleration, reduce your steering throw. If all off these things still give you too much on power steering you could try runing two diff setup instead of a spool. Normally a car that has good on power steering is a fast car because to you really drive on throttle.

Thanks in advance

Default Awesomatix A800X

I had the opportunity to run an A800X for the first time this weekend. The car was a pleasure to build with the amount of attention to engineering and detail. On track, it is very good and I want to thank the community for all the resources, tips, and tricks that have been shared.

If anybody's interested (I'm not a factory pro all star driver), I can post a setup that uses stock parts. If not, that's cool.

Additionally, Roel, a fast local guy who happens to be pretty smart, designed some incredibly precise caster gauges with very tight tolerances. I'm not sure if or when these will be available at hobby shops but you can reach him here on rctech at [email protected] He'll also be at the Reedy Race next month so you can see them in person.

It was great to see you get settled and fast quick! Great job this weekend.

One question about the rear belt tension: I have the bearing housing at the most backward position, but still tension is rather loose. The belt looks good, has most of its brown color still on the teeth. Front is fine though.

Rod- please feel free to share I'm sure some people would love to see the setup from the tamiya track guru

Rincewind- what car/tensionsers? The X car should be able to make it tighter than you need. The older 800 could not get the rear belt very tight, optional cams were released to get more tension (dt10-2, -3)

Will do. The car was very good with the setup I kind of mashed together. I looked at all the X asphalt setups on petitrc, found commonality, and in areas that were different made educated guesses based on previous traditional touring car experiences.

I wanted to try a setup from Brandon but I didn't have the parts that and a couple of Kettle-Sevens prevented me from wrenching and making wholesale changes post practice-pre race.

Not too shabby for its first outing.

Here's a pic of it in action by Rugspin Graphix. Don't mind the wrong stickers on the body

It's easy to forget that the offset is opposite to the little marker "dot" in the housing. If you rotate the dot to the rear, you're loosening the tension. Rotate the dot forward to increase tension.

Glad to hear you guys had some success with the VTD with the carbon chassis. Outdoor season is starting soon so I was trying to decide if using VTD with the 2.25mm carbon chassis was worth trying or not as it was my understanding that too much flex could also be bad for car handling.

rod - did you try increasing your A or B gaps on the front shock?
a larger A gap increases dampening
a larger B gap decreases spring rate

both of these could have helped with your understeer

also, the 3mm of shim and 4mm short wheelbase should produce A LOT of toe in under squat. possibly this was too much...

Hi Mike thanks for the awesome feedback. Some of the guys at the track suggested that I decrease the front dampening to make the front end feel more positive on turn in along with directional changes. I kind of liked the spring rate feel, so I busted out the chart, and low behold, slam a and b to 0 haha Easy change and no measuring. Sure I'll do that Oops.

As for rear spacing to adjust for toe under squat, that's still something above my pay grade. This is the first car I've had with that kind of adjustability. I'm curious to know what the effect of adding/removing spacers to the rear steering knuckle would do. Perhaps I'll just put the car back on the setup station and mess around. That being said, we only had 5 three minute practice rounds to figure things out. Baby steps.

Again, thanks for the feedback. I won't be able to test anymore before the Reedy Race because I'll be heading off to the Caribbean.

Nice job on your first outing Rod.

The rear toe links adjust how much active toe occurs under compression. So if the link is angled down, towards the ground relative to the lower arm. When the arm moves up from resting position, it will remove toe from that side. I'm guessing you know the rest from there. If the arm moves down towards the ground it adds toe.

When the link is angled up relative to the lower arm, you will add toe when the arm moves up from resting position and remove toe when moved down.

When the link is flat to the lower arm it acts like a conventional TC rear setup, no toe change whether the arm moves up or down from resting position.

From what i understand many of the other TC manf drivers that have active rear toe capability like to run it on asphalt.

From to looks of your short wheel base setting (4 deg forward tilt on the rear uprights) and 3 mm of spacers you had a very slight toe-in under compression. Which i believe is the direction others use. A little more toe when squatting would give you more forward drive and stability in the middle of the turn.

FYI, .5 mm can do a lot.

On carpet we like to go the other way. Link angled down, so there's less toe when cornering, loosening up the car a bit. Especially on Black CRC carpet.

Hope this helps. You'll be a pro in no time.

Another thing to try as you gain more experience, is putting larger holes in the damper vanes and using higher viscosity oil.
