    It looks like this project has stalled. However, perhaps everyone will be interested to note that an Open Source Airframe has just been released by the OpenRelief project. 

    Here is an overview of the specs:  
    * Length 1.4 meters  
    * Wing span 1.8 meters  
    * Chord 30cm  
    * Uses counter-rotating motors (redundancy, speed, balance, no torque)  
    * Uses remote servos (wing flaperons, the tail surface) for more storage and ease of repair  
    * Empty weight 3kg 
    * Thrust is 12kgs  
    * Max load 12kg (lift at 100mph/160kph is approx 12kg)  
    * Endurance is between 1 to 4 hours with existing specifications  
    * Wings can be repositioned to change CoG for large payloads  
    * Stringers located on the fuselage to carry the wing, landing gear and other items (modules)  
    * These channels also hold internal items like the motor via bulkhead rings, for quick changes  
    * Fuselage can carry liquids (same diameter as 2L bottle of cola)  
    * Can be launched by rail and use parachute recovery  
    * Can be fitted with front wheels for conventional landing in rough fields

    I am trying to work a Makerbot/Reprap printable airplane. I love your approach on this. I have been having a heck of a time on the wings... but just using EZG wings would make my life SO much easier. Can't wait till you publish them! Likely will make my design obsolete, I hope :)

    The pics are back. I guess it must have been a problem with the website that was hosting his pics.

    Have you seen the RCGroups Maja thread:

    It would be nice if wayne could approach his open airframe design from a "foamie" point of view. A lot easier to repair and more protection for the payload.

    The photos of the prototype are gone. All that I can see is a "?" with a big circle around it.

    looks good, keep us posted. Looks like more room than a big wing easy but less durable of course... nice work though!
