EPP foam for building
I am planning to build a plane this summer. It will be my first scratch build. I am planning to build something like the LightFlite Bug.
I am learning but I don't know alot about Foam. I have two AT-6 planes made from very hard and firm non flexible EPO foam. They seem almost indestructible.
I also have two MS Composite planes make from fairly flexible EPP foam. I had to use CF Rods to make the fuse and wings stiffer.
So my question is, what Foam should I be building this plane out of? I am thinking of building it out of 9mm thick foam.
Here is a pic of a LightFlite Bug.

If it as small as the picture looks, Use 3 to 6 mm at Lowes or Home Depot. Anything over 3 mm is dead weight on a 6 X 9" plane. You can even round the leading edge carefully.

cyclops2, you really need to learn to elaborate on your replies.
What type of foam is that? My Homedepot only has pink foam.

Have you ever seen a pile of folded up blue foam sheets ? Also known as " fan fold ". Ask a guy there. They may be out ,with more arriving soon. 1 pack / bundle will last you for ever.

RE: EPP foam for building
Another source of foam for building is foamcore. Dollar Tree stores have the product for uhhhhhhhhhmmmmmmmmm a dollar!!!! for a 20X30inch sheet and the foam is about 5mm thick. It is sandwiched between a paper cardboard substance. I draw my parts on the paper, cut out the parts and then soak them in water, or you can spray them with a cleaning product called Awsome (available at Dollar Tree) and let it soak and then the paper will peel right off. Also I use a simular product from Hobby Lobby the craft store that is available in three thicknesses, 3mm5mm and about 1/2 inch. The Hobby Lobby paper seperates very easy with just a 2030 minute soak in water and the foam has a very smooth finish. Been useing the foamboard products for 6-7 years and built many planes, works well for me.......
