    Testing of wood wing ribs

    Hi Billski, The designer of the plane I am building did not test or calculate the ribs he is using in his design. The quickest and simplest way, I think...) for me is to test a rib to destruction and ensure it is strong enough Dan G

    Birdy electric motorglider

    This vehicle is a motor glider-most of the time it will fly with engine not in operation. Prop efficiency and noise is less important than simplicity and light weight and mainly low drag when not running.
