Thanks rkramer and AnnMarie.

I see what you mean about the bad implications.

I was able to get full travel on the mixed channel when I realised that the channel 6 flap knob had to be in the middle but that means that if I accidentally nudge that then one elevator changes. The main thing though, as you say, is that the trim wont work on both so I agree it is a thoroughly bad idea.

I'll get a Y-lead reverser.

Many thanks for your help.

Chris.
