Here is the project and the video for the scratch built wings out of purple foam. I wanted a long range wing that did not break the bank. Here are the pics that i took durring the build.
This was a scratch built wing mad efom purple foam form the hardware store. I hot wire cut the wings from 3 peices of foam stacked. Same for the body.

Here is a link to the foam board i used. you can make a lot of things from it. I used gorilla glue to glue it together. and it does sand well there is a clear plastic you will take off before you glue or sand but it comes off easy. I wish I had plans but i built it out of my head. but i did put measurements for the wingspan.
for the CG i used. http://fwcg.3dzone.dk/
