Thanks Majortom;

The slight droop on both ailerons was done inadvertantly, or could have bumped the nob on the transmitter. Since I can control the flex of both ailerons on the transmitter for flapperons etc. I'll probably start there.

The coupling idea might be another idea If all else fails........ good plan, thanks. I should have a chance to experiment more this weekend... I hope.

Thanks Peter
