Gday Jeff, For what its worth I would 100% recommend trying elevons for roll alone on the 16 and use the 'ailerons' as flaps alone ala the full size F-16. I have owned two 1/6 scale AD F-16s and both I have set up with just elevon control and they fly fantastic and roll rate is crisp/fast and very axel. The F-16 is a dream to fly with this set up regardless of scale or manufacturer as far as I have seen and heard. Catch up with you at Temora...

Cheers- Marty
