An amazing model to watch fly...and I caught the operational wing sweep working on the ground and in the air...

Nice model. I'd like to know how the builder managed to keep the centres of gravity and pressure in the same place with wings forward and aft. I tried to do the same, a long time ago, with a slope-soaring Tornado, and gave up in the end.

if you are calm and collected when all about you are going berserk - you've missed something important!

Great question Eric. I will ask Mick when I next see him BUT I do recall him saying there was little perceptible change in flight characteristics with the wings swept and I don't think he has any trim changes programmed in when he sweeps either...but I will ask him.

I made a paper F-14 recently that would allow the wings to be made with different sweep angles. It flew in all configurations without re-balancing and no significant change in wing or tail incidences. I suspect there's a small C of G range where this happens, but outside of that you have to trim with changes of wing sweep
