Thanks for the info guys.

Tried it after a couple of flights with the new model and it made no difference on this particular plane. The plane would happily drift along at walking pace anyway, even with no wind, so the only use I got from it was from what I was incorrectly refering to as spoilerons (thanks for the correction hogflyer), when both ailerons deflect upwards. I used this once after I touched down to hold the plane on the ground as at that point we were getting some big gusts and it wanted to start flying again.
