1. Polystyrene epoxy is not foam safe.

2. Epoxy is foam safe, but only mixed in the right quantities. if you mix the epoxy with the wrong amount of hardener then  while it is setting it will exotherm (give off heat) and melt the foam.

3. some like to thin the epoxy down with NC thinner. The acetone in the thinner will eat the foam. The epoxy is from Bangalore from one Mr. Bashir as also the Fiber Glass.

4. I have used epoxy to make fuselages (using the lost foam Method) and booms as well as covering foam core wings -
I cut my own cores from green foam (40 Psi). cores covered with 48 gms glass fiber cloth - stiffened with Uni directional CF cloth 150 Gsm. The foam is from Vijay Traders Bangalore. The Carbon fiber unidirectional cloth and 6K and 12 K tow comes from Hindustan Fibers Mumbai.

5. I make my own CF rods using Carbon 12K tow.

6. getting 1.5 mtrs wing span gilders (DLG) coming out at 220 gms RTF

if any one is intrested please let me know so that I can put some build pictures on the site

The thing is awesome.
But I think you are reinforcing it too much.

it needs the reinforcement as the glider comes under enormous stress. The CF on the spar gives the rigidity and stops the flexing of the wings. The GF gives the torsional strength. DLGs leave the had at speeds of 140 Km/hr or more with the circular motion becoming a tangent on release. The battery pack wants to go one way while the tail in another direction. The heights these planes reach is anywhere between 120 - 180 feet with a hang time of over 4 minutes. In flight they are known to reach 160/km/hr. lets see how it flies. I will also try and install a rotary
drive system (trying to build one at home using a Parker refill coupled to the servo gear)

have you ever built one? my previous model was based on the Allegro lite with a high start (bungee). same principle with the spar wrapped with Kevlar tow (I got some free from a fiber optics cable

I have made a few MPX models, and use a combination of 5 minute epoxy and thin cyano.

Use ''clear'' epoxy, eg Araldite Clear or Bondite

epoxy resin rate 850 Kg / hardener 100 ml 150 . Ratio of hardener to epoxy is 8 parts epoxy to 2 parts hardener. if a faster cure is needed then the rate of hardener can be increased up to 5 parts (giver 05 min epoxy). This is good for any foam except EPO (will not bond).
I also use a thickening agent called fumed silica which will gives a consistency of normal 10 min araldite.

To order send e mail. They will send you a performa invoice with banking details. money can be transferred to their account.
they also sell carbon fiber tow 3K, 6K, 12K.Please feel free to ask me any other question.
