Hull making
« on: January 30, 2013, 08:55:24 am »
Hey everyone,

I'm wanting to get into the remote control scene a bit. I'm not sure if I'm going for a quad-copter or r/c boat yet, but I'm interested in what the best way to make a cheap hull is. I was thinking of maybe building a simple foam cutter, then once I had my shape using some plastic mesh and epoxy to create a shell. Would that even work? Anyone else into this stuff and have a process they want to share?

Thanks in advance

It depends on your own skills and the desired weight. There are four main techniques.

1. Foam cutting. This may be done using CNC cutter or just by hand with a sharp knife or a hot wire.
2. Making longerons out of a thin wood or carbon just like it's made on a big aircraft. Cover it with thin film, fabric or even paper. That's similar to WWI and early WWII wooden aircraft construction.
3. Vacuum forming out of a thin plastic.
4. Epoxy resin on a fabric or paper. This may be used for external cover of the foam or by its own. Temporary foam inserts are then usually dissolved by acetone.
The difficult we do today; the impossible takes a little longer.

If you make something out of foam use EPP.
EPP foam it's much better, it bends instead of snapping like typical polystyrene does.
