Ok, I am ready to take the plunge on EPP, and I would like some input from those experienced.
Of course, me being stubborn, I would like to scratch build, and I would like to learn some building techniques.
I have been lurking in RC Groups, and much like here, there is lots of info to dig through, and no real centralized place for it. Although the number of know it alls with no actual experience offering advice is higher. I am trying to gather up what materials I need. For the purposes of this experiment, lets say my budget is ~$100 including shipping.
I will more than likely be buying my foam here, as it seems that their prices are decent and they actually have stuff in stock.
So I want to build 3 planes.
The first and most obvious is a 3D profile plane. I have found plans and a how to for these. What thickness of foam do I need, 10mm? Carbon fiber supports/spars?
Next is a full fuselage bush type plane. Maybe something similar to this?

It doesn't need to be a twin. I feel like I could do airfoil wings by either getting the thinner stuff, and folding it around or shaping the airfoil. With that being said, I don't really want to get into hotwire foam cutting yet. I am opposed to it really only on the grounds that my garage is packed full of tools and stuff, and I don't want to add to the mix. I could also 3D print or otherwise make some formers and go that route.
As far as the fuselage, do I want to get the 1 inch thick stuff, and have a thick beefy fuselage, or do I want to do something thinner with some inner reinforcement and structure? I also thought I could get maybe some half inch, do bevel cuts in it, and fold it together in a box fuselage like that with only one seam.
Then I was going to build a profile trainer for my daughter. Probably something like this but a little larger.

That obviously looks like one thicker piece, plus thinner pieces to make the KFM airfoil.
Any ideas or pointers?
