Flying wings?

I know just enough about conventional airplanes and what controls what to figure things out. Wings I know zilch.

I'm thing about buying a Mulitplez Xeno wing . Just looking at it it looks like the fin area is too small and inboard on top of it. A search of owners brings up a question of stability at very low speeds. Probably made worse when the motor is turned off as in landing.

I wonder what happens if you add vertical tips to the ends of flying wings? A lot, if not most wings have huge vertical tips at the wing ends. I had a Zagi years ago that had this feature and it had no low speed problems.

Anybody try this or can guess what happens if you make the tips to large?

" Modification always lead to grief" is an excellent thing to not to ignore but it sure is a lot of fun.

I'd suggest flying it first. If you notice a slow speed fall off or hunting around then add some small tip plates.

You certainly do not need to add a huge amount of area. Even just 2 or 3 sq inches of area at the tips or making the stock fins bigger and extending them further behind the trailing edge would be enough.
