XB4 2wd Setup Advice Wanted

[Alan - South West RC]

Ran my new XB4 for the first time the weekend and ran it in 2wd as that was the only class running. The car was very good and I was pleased with how it ran but I am after a little setup advice. The car was a bit loose on the rear end under acceleration and I was wondering what changes I could make to try to reduce this. The track was a combination of Astro and Grass and was very dry and dusty in places where the grass had worn.

4deg rear toe, softer rear springs, add weights under lipo, loosen slipper, go up a tooth on the pinion, put expo on throttle or just go slow to go fast.

You could use my set up on the Xray set up section , under gwesty .

The X-ray proto got a kick up built in the chassis with custom front hinge pins blocks and a reworked toP deck to screw properly to the angled bulkhead.
Rear shock tower seems different too.

You'll notice on pictures some weight bolted to the RR hanger, I would say around 60g, maybe more. They did that for a reason, under lipo weights might just soften the car reactions, not more traction.
That was the case with the DB1.

The way Glen's car runs as a 2wd faster than most 4wd and keeps up and beats a lot of F2 and F1 drivers in the Mid South region you won't go far wrong from copying his setup

what's the fastest way to change from 4wd to 2wd? if I only have one car and want to compete in both classes. sometimes it can be only 5 minutes between 2wd and 4wd heats..
