how to repair damaged parts under sheeting?
 
Would it be really difficult to repair parts under sheeting?
thanks in advance!

It is easy for a master craftman. It is hard for a klutz. Superman, using his X-ray power, makes it easy.

It you want advise, describe the boo-boo exactly with every fact. A picture would be helpful.

I was just wondering cause I'm a first time builder and I'm debating on whether or not sheeting would make repairs unnecessarily difficult.

Let's just say one of the fuse formers collapsed or shattered under the sheeting.
What would I do?

Design the structure better with lighter weight and higher strength. If the former shattered, it depends on the former. Is the former made of balsa sheet with one grain direction, built up balsa former with two or more grain directions, lite ply, birch ply? It depends on the fuselage dimensions and the uses of the model. It depends on the spacing between the formers. Repair is easier with wood glue type and amount. The wood is 5 to10 times strength with the grain compared to cross grain strength. A simple former with one grain is weak because of its cross grain strength. A built up former or ply wood former is much better.

Are you worried about the former shattered because hanger rash or flying crash? Be careful!

Avoid the boo-boo by careful flying. Don't fly beyond you flying skills. If you don't have enough flying skills, get a teacher to help you flying at high alitude.

You can go to my Stuka buil thread or my blog to see the pics of the formers, but for now, that is gonna have to be the best solution-don't crash :D

oops, this thread is supposed to be in builder's workshop... dang!

Put two 1/16 x 1/16 " balsa sticks to build up the former so it doesn't crack short cross grain either end of the former. No problem!

aha! I'll try that, thanks for the advice!
