upright fixtures shown here are to prevent the fuselage from sliding
back ad forth.
The other two
hold it down.
Note the clamp blocks.
Sponge shelf lining (available at Wal-Mart) is placed
under the fuselage to protect the
antenna exit which is a balsa stick that is routed and shaped.
really like this shelf liner material. It is thin and won't slip (when
it's clean) and provides excellent padding for components.
My models have far
less hangar rash than they used to. I bought several rolls of the stuff
and have cut it into various sizes. For example, I have a piece under my
table saw which used to slide all over my work bench.
Sawdust sticks the shelf
liner which makes it lose its stickiness, but it can be rinsed or washed and
works as good as new.
