Hey Ray no problem that's a mistake most of us made when trying to sort this stuff out.

Hugger now not completely sure but with the Futaba system the trainer box must be 2.4 (fast) and since it broadcast to the 2.4 little bitty 2.4 receiver that dangles out the buddy cord plug on the back of the master and that info procedes to the master via the buddy plug, I do suspect that the master may be able to function on 72 from there to the airplane. Agine this is just speculation but I'd bet the limiting factor of which futaba you could use as the master is only the version with the square trainer plug.

If anyone knows any further info on the futaba please let us know.

Bruce thank you for your support and I agree with you that those who not have tried it then don,t knock it, Frankly because you simply don't know.

Dennis yes indeed and I too sure miss those days. At one well known 'small' airport out in Chino California before there was a tower out at the intersection of the two runways they had an old park bench for the instructors this in the middle of nowhere but a grand stand seat for watching your student do his obligatory three. At that time there were two operational firefighting B-17's based there and can remember on several occasions having a student up and sitting on that old park bench when the B-17's made departures. now that bench was right there what a grand seat that was.

On one occasision that I definately remember was the student after he did his three he was so excited that he took off and flew home to Brackett airport our home base completely forgetting me out in the middle of nowhere! Chino was the training magnet for entire inland empire area.

OK sorry for digression
