Err I just wrote a long reply explaining my similar experience then I accidentally closed out of it. Here are some links that I saved while researching the same subject in the past. I am not sure if they are all still valid or if they are relevant. Hopefully, you can find something helpful in one of these. I ended up just going with a tray and a neck strap. With a lot of practice, I can fly a fixed wing decent with my thumb and pointer finger. Best of luck, message me if you want to discuss further.
