does this wing loading sound right for habu vs habu32 ??

huge difference if i did the calcs correctly...
foamy habu ... 30 oz / sq inch
fiberglass habu 32 ... 100 oz / sq inch
3 times the wing loading ... would that seem correct ? in big round numbers .

RE: does this wing loading sound right for habu vs habu32 ??
Your calculations do not seem correct.
The stock Habu 32 weighs 7.4 lbs, which is 118 oz. Wing area is 392 sq. in., so that is a loading of 0.30 oz per sq in.
I could not find the exact sq in spec for the PZ Habu wing, but scaling it based on the wingspan difference, it is about 80% of 392, or 314 sq in. Weight is 2.8 lbs, or 45 oz. so the wing loading is .142 oz per sq in.
The ratio is about 2 to 1, not 3 to 1.
