Wazzbat, while I'm sure someone will (hopefully) correct me if I'm wrong, if your buddy boxing with someone and your on the slave box, I'm sure that most radios don't care what mode your on - as as far as I understand it, if yours is mode 1, and the instructor with the master box is mode 2, they will both stay in their specific modes as the buddy cable transmits elevator, throttle, rudder commands etc, not the actual stick movements (as in the same way a receiver will work with any mode, it just receives throttle (etc) signals, not left stick said to do this).

That's probably a good point kiwibob. I never actually thought of that. But I'm not going to change back again. I might end up getting really confused then.
