my car touched the pavement for the first time today. just to get a couple things adjusted. i'm looking for a couple answers though, how tight should the diff be? adjusted it like the instructions said and it was way to loose (i think), i tightened it up a bit so that it wouldn't just slip when you hammer the throttle. now it may just lightly slip for about a foot or two and then it's hold on! also, anyone that's using a sphere esc, what do you have the esc set at? right now i have it set like my touring car, 1-4-0-0. i may need to add more brake.

i definently see how people say you need to roll into the throttle with a pan car. with this 10.5t, it looks like it will very exciting to play with.

I have mine set as loose as possible without any slippage... That said, we are running Speed Spec class with 21.5 on carpet. However, I also have a Speed Spec we are experimenting with running against standard Formula Pro10s, again, diff as loose without any slippage. I think I am running all the diff balls in the gear for added grip and added looseness of the nut. I run Kimborough 100t with the 13.5...

I am running the Sphere TC (in the experimental car) because that is what I had... Settings are basically no drag brake, standard initial brake, and full punch. I'm at work and don't know which setting is which right now... Again, this is on carpet. I weighed the chassis the way that it sits, and it is under weight... I found this interesting.

Timmy - I might have been wrong about the weight. IIC Vegas World GT rules require 40 ounces = 1 133.98093 grams. I think you were at 1140+. My Formula 10 was in the 1,000 zone.

took the car out again today for some real driving. it seems as though when the car gets up to speed the leading edge of the rear pod drags the ground. maybe from the amount of downforce that's pushing on the car is making it contact the pavement?



so what do i have to adjust to stop the pod from dragging? adjust the rear spring? change to a stiffer rear spring? change shock oil? etc...


i would like to note that with the lrp 10.5t and lipo combo, this thing is a rocket! i can only imagine what a mod car will do

You can adjust how high it is where the pod plate meets the chassis by the preload on the center spring. However when resting on your setup board, the center point where they meet should sag a bit lower than the rear ride height, so don't preload it to the point where it is the same ride height at that point as the rear.

Check your ride height front and rear. With a hotter motor in your car, the tires will wear faster, and you will need to compensate for the wear by keeping up with ride height changes. For asphalt you may need to get the chassis higher in the air to prevent chassis rub. I know on carpet I keep mine at about 4 - 4.5mm front and rear, and about 3 - 3.5mm in the center. I think I am running a copper spring with .020 in the front, maybe .022...

Keeping the chassis off the ground is the way to turn faster laps. If it's rubbing, you will be loosing time, and handling.

Most hobby shops carry Associated VCS shock springs. I did a quick Google and this came up...

I've never used that on-line store, but it looks ok.

You most likely need a Red.

I get my springs from Speed Merchant. Other brand springs will fit the center shock, as it is the same diameter and lengths as other 12th scale micro shocks.

Low ET: when you chassis is on your pit board is the chassis and pod on the same plane? I.E. does the pod hang below the chassis when they are pivoted parallel? I find it strange that the leading edge to the lower pod plate is rubbing and not the trailing edge of the main chassis...

yes, everything is in the in the same plane. with the car setup, there's maybe 1mm of sag at the pivot point. ride height is set to 5-5.5mm all around so at the pivot it might be around 4-4.5mm.
