Lower Fuselage Foam & Glass
 
 
 
My oldest daughter at age 7 helping sew the foam to the stringers.
Needed to fix that one.  Fold-a-plane is much easier.
 
 
The foam can be formed with a heat gun.  Have plenty of fresh ventilation as the fumes are toxic.
 
 
 
 
 
 
Post curing.  Simple oven made with Celotex foam available at the local home improvement center.
