That's funny. I had to read Pat's post twice to make sure I read the right wing loading.

8 oz wing loading to me is unbelievably light. Especially for this model.

Can't wait to see some in-flight pics.

I recommend a keyfob cam looking out the windows for the maiden flight.
Followed by AV flights over the actual Grand Canyon, of course.

Yep, Pat thinks it's about right when it is closer to 5oz/sqft

Beautiful model Pat! Do you laser cut your own prototype models? Just curious.

I don't have a laser, the parts come from Manzano Laser Works and are the test shots that are proofed and corrected during the build. Then the corrected files become the production parts.

Yeah, 5 oz. / ft. Now that's a number I like But, with this big fat airfoil the volumetric loading at 8 oz. / sq. ft. is probably close to the same, or lower, then the typical 12% thick airfoil with a 5 oz. loading. Can't wait to see how it works in real life.

It looks to me that with that big fat foil and power off on approach, you will have to dive at the ground to keep enough airspeed to fly. Looks like a really draggy airframe. I love the looks though. Best wishes and good luck.

Tony, I've found that with any multi-engine airplane that you need to carry power on approach -- or, shut the power off altogether. The drag from (2 or more) prop arcs turning a slower pitch speed then the model is flying is right up there with "slamming on the breaks" and the model will sink like a stone. However, even the B-17 with its 19% thick airfoil glides fairly well as long as, like you say, keep the nose down and the speed up.

What holds the outter wing panels onto the center section, friction? Is there some sort of retainer to keep them from sliding out?

Talk about slamming on the brakes, my P-61 with the 4 blade props seems to almost stop when the throttle is cut. The first 'landing' was an interesting learning experience.

OK, talking about light wing loading..............I built Pat's Standard J-1 and the wing loading came in at 4oz's per square foot. Fly's GREAT!!!!!

Maybe Pat could do an Antonov AN-2 next?
