First Post! of this site that is, so it's rough, sorry!
Here's my theory, replace standard crystal based radios with a computer controller using an 802.11 wireless network and custom equipment.
In theory you could have infinite "channels" per model, and you'd have no interferrance. The logistics of
developing a small computer controller to replace the traditional Rx are what will most likely kill this project. I see
the development cycle including converted old controllers as joysticks, sending commands via an Access point, to the Rx
in plane. Then developing that into a small Tx sized unit to replace current ones.
