I have a doubt after playing around a bit with some pipes, some plywood, etc. that instead on complicated weight shift mechanism, can I use a system where actual aileron like control can be made possible? ( pulling on the end of the fabric so that one part of the "balloon" comes down and doesn't produce lift while other side produces lift causing a turning force)

I need some comments on this idea before I proceed doing anything.

Devised a system for adding roll axis control. You will soon see how.

Added Roll axis as well as pitch axis controls.
Might work or might not. fingers crossed.

Can i use two servos with their arms parallel in elevon mixing to control the wing?

Does this use elevon mixing?

I guess NO
