So, should I tape down the stabilizer parallel to the table and then tape/weight down the nose and the middle of the fuselage prior to sheeting the rear part of the top? Or should I start with front top sheet first and work my way back to the rear? The twist is limited to about rear 1/3 to 1/4 of the length. The front 2/3 to 3/4 is appear to be OK. How about using a steam iron application?

No, I dont have building jig and yes the formers are marked in the center (as close to 1/16!QUOT! of difference). I suspect the problem is the balsa was slightly warped when I was assembling the sides together.

By the way the sheeting as called out in the plans are 3/32 balsa sheet to be laid 90 degrees perpental from the fuselage sides (grain not running same direction as fuselage). Is there a problem with that that might compound twist even more?

Thanks!
