Idea
Sandwich coro/foam

Hello all

Not really a new idea, but an interesting concept, I was looking for an idea to build a very strong fuselage just 3 or 4 hours....

The general idea is to draw a foam fuselage of 50mm and cover with coro!
I made a very basic prototype to test the concept with the "Mochtang." For the 2nd model, I chose the Mig 3 and I try to forms "softer"

The photos may be clearer than my English ! or Chinglish !!

Plotting






Cuts



Sanding



Preparation of the motor mount



Filter the rear part with a hot wire



The engine mount is bonded



Dress with coro






A soon to step 2

I really like the idea and your thoughts on how you did it. It does look really good. So keep us informed as to your progress. That method does make for a strong stiff fuselage.

Hello rockyabq

I cut with a fine saw blade type "Dremel" or "Hegner", and the hot wire, just the tail.

Oh that is very nice looking! I have a somewhat similar deign I am working on for a foamy, but haven't had any luck with getting the rounded wing tip right yet. I like your solution. Very nice styling on the paint job too.

Ah, that would explain why it is so consistent and smooth.

BTW, I couldn't tell from the pictures; how are you doing your wing attachment to the monoblock?
