Thanks Wellss, D Hanson and S Wind,

I am really uncomfortable with a left roll tendency built in to a scale warbird and am somewhat reassured that it shouln't be a major issue. I still think loops would be adversly affected and it would always be a mental distraction on take-offs.

This board and the folks on it have always been a wonderful resource for inspiration when I hit creative brickwalls. you guys have once again pointed me in a good direction. I plan to pursue an incremental approach from least invasive/agressive to more so if or as required. Heat pad and opposite twist bracing/pressure, heat gun and greater force, cut it up. After 20+ years to get this far it doen't make sense to get in a hurry now so if it has to sit in blocks and braces for 3-4 hours or 3-4 weeks and the problem fixed and finish saved then that'll be great. If not, it can always be painted, decaled and weathered again.

Thanks again, I'll post results in a few days/weeks.
