I realize no one wants to hear about this, but once again, here is the cause of the problem.

In a nutshell, here is how I've solved the problem, but only locally.
1. Hand the tx to whoever I can get to the flying field.
2. Show them how easy flying RC aircraft really is.
3. Have them land within 15 minutes of the first flying experience.
4. Show other instructors how to do this within 30 minutes.
5. Show school teachers how to fly and then teach RC flying.
All of the above is very easy for me to do.
