Hello, I am from the Detroit Michigan area and would like to introduce myself to the global modeling community. My professional background is in mechanical engineering and testing. My hobbies are radio control aircraft and now card modeling. My area of cardmodeling interest is aircraft load bearing structures. I am currently designing a cardstock electric powered remote control aircraft. Thus far I have made 25.4 cm long (10 inch) wing test sections with a 12.7 cm chord (5" width). They weigh 17 grams each and are covered with a plastic shrink covering. Calculations and actual tests have shown that they have the required load bearing capacity and torsional stiffness. The actual aircraft will have a 76.2 cm (30 inch) wingspan. My co-workers are amazed at the strength of the cardstock wing structure. In the future I hope to design flying scale models and cover them in paper tissue. I would like to thank everyone here that has shared their knowledge of card modeling and hopefully I will be able to contribute also! Will post pictures as soon as I choose a picture hosting service. Thank you and have a nice day!
