FB - As Evan says the fuselage is, literally, supposed to be carved to shape from a solid block of balsa approximately 5"X4"X48". Once this is done it is then hollowed out to a wall thickness of 1/4". No thank you - if I were building it I would use the normal sides, big corner triangles and thick sheet top method.

The plan is available from www.myhobbystore.com (Plan RC/1127 but for some reason listed under "powered scale free flight") I have a copy bought years ago from RCM&E (plan/article published in the April 1972 issue) which you can certainly borrow to copy if you prefer. E-mail if interested.
