I have seen these chassis work on King tracks and Hillclimbs, they work really well.

How to tune these for flat tracks?

Any help would be appreciated.

I tend to use a medium weight pan for flatter tracks. Car seems to settle better.

I recently saw where Jerry Herbert won a flat track race using the ultra light 2 piece pans, so I would say they work real well.  One thing you should understand first, Jerry Herbert is an exceptional flat track racer and he could probably win with just about any chassis.  Even so he chose the ultra light steel pans and not the two piece aluminum ones.  I would most likely choose something a little heavier.  As far as tuning the chassis, from what I could see there was no added weight and just pin tubing for body mounts.  You can see the chassis Jerry used on the Mossetti Facebook site.

I don't race Flexis but having seen these chassis, they do look incredible.

I hope Jerry Herbert is on SlotBlog and can chime-in here.  Sounds like he could share some light on these chassis. At my local track some  racers think they don't work on our flat track. I believe it is a matter of tuning them to fit the track.

What body style and motor are you racing with? This will change the setup you need

Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free. - Ronald Regan #40 (1911 - 2004)

Flat track use the standard pans, not the alloy or super light ones.
Standard Piranha is what we use, or sometimes JKB.
Have as flat as possible and experiment with body position.
Try a little lead as needed, don’t be afraid to add weight
Start with guide flag pointing up slightly, and the chassis front wings just touching the track.
