I run the screws simply because the top deck bends when I try to push it down to use clips. I prefer to tighten the front two screws down until the deck starts to bend then stop. The gap between the chassis and top deck is a little bit too small for Orion 90c Lipo's I find without the chassis flexing, Woody only suggested the clips for ease of removing the batteries it's nothing to do with handling.

The DB1 is the best high grip astro car. PERIOD!
Its honestly the best car I have ever driven. That thing is like a missile.

I drove it once at Bury last season, And it was QUICK!

Although, Then I will break the vega out....

Chris it was actually bent nr the very back, only slightly but I believe now that this has been the main reason I have struggled with mine.

Alan, I've noticed that the car can suffer from chassis tweak but I haven't experienced any actual bent chassis? The sv2 can easily start to suffer from strange characteristics due to the double deck chassis which makes chassis tweak more likely.
When fitting the Lipo's to the chassis only screw the top deck down with the front two screws and leave the rear screws out. The Lipo's will stay in place with only the two screws and will offer a little more rear flex therefore grip. When tightening the screws down on the top deck make sure you gently screw one side in a little, then do the other side before going back to the first screw then repeating the pattern little by little until you've tightened both down.

I know this might sound very anal for just putting your batteries in but if you screw one side tight down first this is a telltale way to induce tweak to the chassis which car make the car steer differently from left to right and not break in a straight line. I went out for a run and the car was all over the place so I took the top deck off and re fitted the screws and the car was miles better so give it a go.

As I said earlier the tolerances of the chassis are very rigid and precise so a tiny bit of tweak can throw everything out.
