Thanks for the support guys. After talking with the LHS owner and one of the instructors at our club, they dont have seem to have a problem with me teaching, even though Ive only been flying R/C for just under 2 years at present and have only transited to flying Glow powered models in the last few months. They've seen me flying and knowing my instructor background have no problem with it, or at least they didnt object.
So Ive ordered a Rx crystal for Hitec and Futaba, (apparently it has to be made for me as Futaba dont make even numbered frequencies (36.560) but wont cost me anymore than an already made one). I have friend whos been struggling to find an instructor and the time to fit in with him, plus he's been trying to learn on mode1 which he finds foreign. He's not a full scale pilot but has been a flight engineer in the airforce on the Orion and lately with Qantas on the 747's unit he was forced to retire due to injury last year. During that time he's flown the simulators many times and of course watched the pilots flying for thousands of hours and feels he may get a better grasp of it on mode2, so at least Ill be able to take him up and give him a shot at it with his trainer equipped with Hitec gear.
