Help to Make a foam glider wing

Hello I have recently aquired a MRC Young Star glider. Problem is it doesnt have a wing so i was thinking about making my own. Now I've thought abput this and there are two major ways of going about and doing this.

1. Going to Home Depot and getting a sheet of like 2 inch foam and cutting/shaping the airfoil myself. Then putting carbon fiber for strength.

2. Making a foamboard Wing like FliteTest does with their Planes. Also with Carbon Fiber. Building a wing like this one http://flitetest.com/articles/ft-simple-soarer-build

Any help would be appreciated.

At least we need the weight of the fuselage (with servos, batterie, rx) and the planned size of the wing (root/tip chord and span).
Foam wings are typical made by the "hot-wire" technique, because this is the way to get a good airfoil quality. Cutting/shaping will not work. If not hot-wire then try the foamboard (Depron) method.

I just watched Curtis Suter's guide to cutting and bagging foam wings and his method for making wings using foam, glass cloth and Polycrylic seems very viable to me, especially if you're only going to do a few wings and don't want to invest in vacuum equipment.

Everything you need is in that video- I recommend that you check it out if you can.

I pulled my garage apart to get to my YS. Here's some info for you about the wing. WS 62.375. Root 6.25 tip is 3.5 and the thickness is at least an inch at thee root. Me think's a 15% Clark Y would do it. here's a couple photo's.

Here's a piece of data I forgot dihedral. 3inches under each wing as there is a center section that is basically flat.

dmtuska, just how handy are you? I may have some cores that you could try. They are RG-15 airfoil. Are you familiar with Chatfield or Zion/Lookout?
