i was thinking and you see those vertical stabilizers on the sides. what is you were to add a hinge on the front and have a push rod extend the rear out like a duckeron but turned 90 degrees until vertically
Delta wing/flying wing kind of setups are normally very stable from the wing slant. If your B-2 is having stability problems, I would blame your airfoil more than anything, I found the airfoil can make or break the flying wing.
Here is a wiring diagram for the plane, I used my rudder channel for the nose gear. You CAN NOT use the rudder channel for one of the duckeron mixes, it won't work.
Regarding your wind comment, my plane handles the wind perfectly, much better than many of my other parkjets. I think it has alot to do with the weight, airfoil, and size. As you can see, it sports a 4 foot wingspan! But what I didn't mention, is the AUW of 22 oz! The wind like gestures the plane around. Gusts make landing difficult, but the plane otherwise handles the wind VERY nicely. I couldn't be happier with this design, it has out performed my expectations in every way.
P.S. I didn't have ANY gyros plugged into that plane, it is THAT stable by itself!
