DEX210: On-power understeer, off-power oversteer

[Origineelreclamebord]

Hi everyone,

I'll be racing my DEX210 on sunday at the Model Indoor Oss (MIO) track in the Netherlands. I've put my car on a basic setup for carpet.

I don't really have the time to go training tomorrow, but I don't want to come to the track unprepared. I found a small patch of carpet locally to test the car. I'm happy with the fact the car doesn't grip roll at medium speeds and agressive turn-in, but there are however some things to work on.

For starters, the car has horrible on-power understeer - all front bite just disappears under high throttle rates. The other thing is that the car feels hugely agressive off-power: the rear end is only just hanging in there and is on the verge of sliding.

The two contrasts are a bit of a problem: cancelling one out may well make the other one worse.

This is my setup:



My theories:
1. The increased rear droop is causing the off-power instability.
2. I should try running pins on the front.
3. I need to try 25 or 20 deg. caster.
3. I need to lose the front toe-out.
4. The 24g behind the battery can be removed.
5. Loosening the slipper might help.

The place where I ran the can today will be closed tomorrow. What are your thoughts on the required changes?
