I meant lower than on the Spixteen....the VIII isn't clipped
You'd think so, but DokGonzo's site lists the Spit16 and Spit8 as practically the same in turn radius both flaps in and flaps out. Although I will admit the 8 seems more user friendly pullilng a harsh turn, less likely to drop a wing.
However, because the Spit8 carries somewhat more fuel, it is possible that if they were both tested at say 50%, the Spit16 would have an unfair advantage. Possibly the Spit8 would turn tighter with fuel loads that yielded similar full-throttle times.
