Clipped Wing

[lake_harley]

In considering an aircraft design I understand that the stall speed would be higher with a reduction of wingspan. Would the increase in stall speed be fairly linear, in relationship to the % of the reduction of the wingspan? (This borders on Mark Stull's "wingtip losses" thread) Specifically, I'm referring to a 10% span reduction, not a greater amount like 25-30%

Concerning climb rate (FPM) and cruise speed, how would they be affected using the same HP engine in a standard version vs. the clipped wing version? The weight of the clipped wing version would be slightly less, just by the reduction of wing structure, but I wouldn't think enough to significantly affect performance by itself. Would the ROC and Speed suffer or benefit from a 10% wingspan reduction, and in simple terms, why?

I have been reading Raymer's "Simplified Aircraft Design For Homebuilders" and so far it hasn't been simplified enough for me to ferret out the answer to my particular questions. I have a particular ultralight in mind but I'd imagine the answer(s) would apply to all small planes.

Thanks, in advance
