Looking for some DECALAGE and STAGGER angle numbers on a Staggerwing

I've built a couple. I treat them the same as a regular biplane. I use 0 degrees decalage, about 25% stagger and 1 chord gap. If you're not planning on inverted flight and want a nice safe stall, use 1 degree or so positive on the bottom so that in the event of a stall the plane becomes nose heavy and flies on the top wing.

The Beech Staggerwing had - I believe - 1.5 degrees positive in the lower wing. Flight reports I saw said you could pull the stick back to the point where the front wing stalled but the rear did not, and you could descend in a bobbing motion. Or you could stall them both with more stick.

If you're planning on a hot aerobatic model I'd just go for zero all around for all surfaces and the motor mount. But I'd put in roughly 1.5 of right thrust.

If it'll be a slower flying model that will be upright most of the time then +1.5 on the bottom and zero on top with the stab set to -1 will work nicely.

Our model size wings at the weights be build to means that the wings are working far less on our models than on the full size aircraft. So the angles of attack we typically fly at are a lot lower on our models. This and our typical practice of flying with a more rearward CG location than full size means we don't need a whole lot of angular difference in the wing panels or from wing(s) to stabilizer.
