Looks cool! "Arcel" foam (not familiar with it) and similar design to the Weasel. Looks like AUW has increased a bit to 5.5 to 6 oz... Edit - I should have kept reading: What is it? ARCEL™ foam is a blend of polyethylene and polystyrene foam. The polyethylene provides toughness and the polystyrene adds a greater amount of rigidity and stability than that of EPP (for a given density). ARCEL is not brittle like pure polystyrene and will not flake off. While ARCEL may not have the same "bounce" quality and dent resistance of EPP, its superior stiffness and stability allow us to achieve a delicate and refined "no covering required" design that is ultralight, yet rigid and stable enough to withstand many sidearm launches. Why? While we think there is no substitute for EPP in "rough and tumble" type gliders that see alot of abuse on the slope (like the Weasel), ARCEL made more sense for the Alula given the glider's thin wing and low weight design requirements. A few other benefits of using ARCEL are its paintability and sandability, which allows one to sand away the small surface vent marks resulting from the molding process (for cleaner looking and more aerodynamic surfaces). |

COOL!
I asked about ARCEL foam a while ago. HERE I got my son a small chuck glider made of the stuff a while back. I got it for him because I wanted to check out the foam. It's super rigid but way tougher than styro. If it's in fact the same stuff I think it is, it should be perfect for the Alula. mark |

I believe the FMA wing was called the Razor, i may have to dig through my old stack of mags for the material confirmation, but what better way to kill time till the new alulas ship out
