Some time ago I was given a foamie BF109 that was in pretty bad shape. Apparetly it could stiff fly though!
It has been stripped down and all the electrics checked out (the all work).
I have glued the fuselage back together and added carbon strips to the fuselage, vertical stabaliser and rudder.
Thin foam-safe cyano was used in each case.
It has also had a few coats of foam safe primer.
I intend to paint it in bright colours rather than the original warbird colours. I'll probably go with yellow and red.
