design properties of a sick roll rate

[opualuan]

I am in a scratchbuilding mode, and I want to build something that has a sick roll rate. I'm talking snap rolls of many, many a second, is fun fly the term? what design contributions make for such a high speed roll rate, I know it's more than throw and airfoil, is it the weight being very centered, etc, what is needed to acheive such roll rates?

[Sparky Paul]

Low aspect ratio more than anything else. 3:1, or 4:1. Large ailerons.
Check the SIG FAZER for proportions.

Also a tapered wing will help with the roll rate.

[opualuan]

tapered, ok... what about sweep? or does it matter?

The main effect of sweepback is to introduce yaw to roll coupling. This makes axial rolls more difficult to perform, somewhat like dihedral.
