[NSRCA-discussion] OS 140RX Need Help (Final update)

[Budd Engineering]

FWIW, a horizontal doubler plate made from either ~1/4" soft balsa, or  
a built up balsa frame (similar to the "ladder" that Dick Hansen used  
to put into his Elan's and E=MC2's) installed at the location of the  
creased section of the fuselage would be stronger and lighter than a  
glass layup that adds little to the skins structural modulus.

Just my suggestion based on having made that type of repair before.
