Default Turning under throttle

I need some setup tips for making a 1/10 4wd buggy turn better under throttle. Currently if I'm going very fast and I shut the throttle and turn the buggy turns on a dime sometimes even rolls over when traction is superb. However the more throttle I give it, even from a dead stop, the bigger the turning radius. To some extent this is expected, but at full throttle my radius must be 30', it really doesn't want to turn while on the gas. The servo is definitely turning the wheels, I think the root of the problem is the front wheels aren't finding traction. I increased the preload on the rear shocks to put more weight forward and that helped some, but there's got to be more I can do. Any tips are appreciated!

but some weights on the front bulkhead, and see if that would help underpower it works great on a 2wd atleast.
i will help the tuning when underpowered.

You can also try running less anti-squat. This will decrease rear traction on-power, giving you more steering. Just remember, whatever you do, its a tradeoff and you need to find the right balance. Less front droop should help you a lot and if thats not enough, then try less anti squat. Just be careful not to go so far you lose your corner entry steering.

Thanks guys; I tightened the preload on all of the suspension and that made a big difference. The car sits a little higher but turns a lot better on the gas.

hmm.... It made a very big improvement, my turning radius on the gas is 1/2 what it was before I made the adjustment. I think the suspension was too soft before and the car was squatting down and sitting on the chassis causing the wheels to loose traction (I'm on grass). Now the suspension stays up in the stroke and the tires hold traction much much better while turning.

the car may have been bottoming out in the gross with the grass being so high and the small car. so with the suspension lower it was scraping the crap and pretty much just sliding. and when u raised it it sits above the grass more so it was turning better. depends on what u normally run it on. if u run it on dirt then you'll probly need to drop it lower

Thats what I was thinking. Kinda high in front, med in center, low in rear. Don't know what rig so can't give numbers. Check them diffs.

Thanks guys. This is a Kyosho DBX (price point rtr buggy), and I don't think it has oil filled diffs but I will check.
