ok Cees

thanks for reply and info. quit work temporilary on fuselage and now working on wing.
at the stage of construction of installing the leading edge. went to hobby shop to pick
sheeting which appears to be softer and maybe<hopefully> more easily bent around leading
edge of ribs. if successful will post pic of wing when this step is hopefully completed.
I had always used ammonia solution to make the balsa more easily bent but my buddy at
the hobby shop suggested I use white vinegar, said it worked much better so going to give
this suggestion a try.
did you receive my question about the leading edge curvature installation? I read somewhere
may have been on this thread to draw a line down center of 4" wide sheet and center this on
ribs<going thru the bent installation as suggested> and gluing this on first then when glue dries
finish the leading edge top and bottom sheeting. your thoughts here.

again many thanks for your help and suggestions, been extremely helpful and appreciated.

can hardly wait to see it this dude will fly. first construction from plans in about 20 years.
things slowly coming back. last kit built about 10 years ago.
not really a great arf fan, have always like to fly what I build, but at 82yrs old things sure seem
to move very slowlyha!ha!

thanks and happy flying
