I have just purchased a second hand Christen Diffusion Magister without a handbook or any information about balance point or control throws. Does anyone have experience of this model, it is the 69in span (1.7m) version.
Thanks.

Balance back edge of the tube. 15mm up, 13mm down 25% expo Ail. 15mm each way 30% expo Elev. If you mix the tail for rudders 12mm each way 40% expo. (stand either surface vertical and direction as a normal rudder)

Long flat approach..oh, get ear defenders ;-)

Thanks Dave. I think the model I purchased was the one you had a hand in building for the review in Jet International many years ago.
Thanks again
Alan.

Not really, was built by a friend, for a friend, only input was supply of parts and advice on equipment. Flew it a few times.
