This plane was acquired at the Denton Swap Meet August 2008.  I had seen it fly several times at the Denton club field.  One of the brothers simply tossed it in the air and the OS.46 took it from there.  The classic fun fly airplane.  A few years later I stuffed it into the sod at the Johnson Co Field during some stupid spot landing fun fly event. (Me stupid-spotted it I did).  Everything from the wing forward turned into splinters although the engine survived.  The remains hung on the garage wall for many years.  A few months ago I saved the remains from the trash can during spring cleaning and decided to attempt a rebuild.

Foldout plans for this plane were published in the April 1984 issue of Model Airplane News.  Midwest kit’ed a heavier modified version.  Designed by Dan Santich to fly with a .15 to .45 engine, I decided to replace the O.S. 46 with a Magnum .28, hoping the weight saved would offset the lesser power and give it a little more gentleness.  I built a cowl around the engine, added wing fences to protect the wing from wobbly landings, replaced the landing gear with lighter stock, and used lighter digital servos and a LIFE battery.  And of course a new Monokote covering scheme for senior eyes.  Had to add one ounce to the nose.

It flies great!  Three flights now, had to take some play out of the left aileron and adjust the throttle linkage.  It will slow flight a circle tighter than my U-control lines and then accelerate to zip by and pull into a vertical climb.  Wouldn’t want more power.  Landings are stable and easy.

Build one for yourself.

I have CAD enhanced versions of the original MAN plans that are easier to follow.  I can print out copies that you can cut out and paste on the balsa as a cutting guide for the parts.
