Joking aside, maybe you could make a “copilot” app that allows the pilot and another person on a different device to fly, maybe using some of the framework from that one app that allows you to control IF from your phone.
Probably not realistic, but who knows? Maybe you can do it.
Whilst I commend your want to release your work for free, have you considered how you will fund the fees for Google Play/App Store registration? Are you going to be focused enough if there is little end reward?
Also it would be very bad etiquette in this development community to release something someone else has already done (very well), for free. That’s up to you how you see the ethics of it, however, just my view.
I’m just warning you not to go around making promises and saying stuff like this, when you have likely not set anything to the ground or planned anything out. There’s a reason FDS with IF and Cameron with LF don’t go around promising things until they are 100% set in stone.
