I'm starting a high altitude return-to-sender balloon launched glider project. I want to keep it simple, and I think my first decision is airframe. I'm wondering if it would be feasible to use a small glider like this mini swift for rudder-only control. The idea would be to have a fixed elevator, set for a fairly steep glide ratio (like around 5:1). It seems like this is how thegps boomerang work…
