I once worked on some IAC competition planes that went to the Worlds Aerobatic Competition.
Have you done anything else on the aircraft? Although it's been a while since the thread was active, I just ran across it today. I've read the entire thread while taking breaks from work around the house. As consistent as the rolls are on takeoff, I would look really hard first at the flaps for asymmetrical deployment causing asymmetrical lift and then, as you have said and cheat the balance forward a hair. I think the takeoff speed is low in the videos. Does the wing, with the plane sitting on a level surface, have a positive angle of attack? That could cause early liftoff that I wouldn't really consider to be rotation. I've seen trainers do that when new builders had the nose gear too long. If I build a tricycle gear plane I like for the wing to have just the slightest negative AOA so it doesn't float or bounce so badly on an otherwise good landing. I also think the suggestion to go to 2 blade props until you get this sorted out has merit.
APC lists 10x8 (glow) pushers and 11x8, 12x8 and 13x8 electric pushers so you could have counter-rotating props for testing purposes, just to eliminate prop torque from the equation.
Your airplanes are beautiful and I wish you the best in having successful flights.
David your kind words are VERY appreciated Sir!
I think I simple rotated WAAAY to soon on takeoff causing a stall, Miss Sabena is fully repaired and should be out there again soon!
