Default Fly it or hang it up?

Recently given to me by my uncle. Fly it or hang it up? Scratch built with automotive paint.

Good news it looks well built.
Bad news it isnt an all out speed plane.

I would fly it the way it is. To me it looks like a high speed 3D plane lol with the size of those control surfaces.

Or you could sell it as a one off (loose) speed plane.

It is a speed design, although a 30+ year old one. One of my uncle's many self design/builds. It is actually mostly flaps not all ailerons, only the outer 5" or so are ailerons. The engine is a pumped OS RF 61, not what I expected to see upon removing the cowling. I would have though a VF perhaps.

Not sure about it's recorded speed but it was radared back when the only person to fly it (pattern flyer Bill Cunningham) took it up for a few test flights. I believe 160 plus was the recorded speed.

I fly slow 100 cc Yak's etc, probably not qualified to fly this. Maybe the speed rally is a good place to put it in the air again. I will post more pictures later.

David.... You've got significant stick time, so give it a shot. You don't have to firewall the throttle on it. I would expect that on your third flight with this thing you would be ripping down the runway trying it out full bore. Go for it! The only reason to ever hang up a plane is if you think it has become unsafe. I had a ship once that had cracks around the glassed engine compartment and was afraid the big FSR would just rip out some day.

Cool design.

You can always rein in the top speed with prop choice (as well as throttle of course), same as test flying a .46-50 delta with a 10-6. I believe 160 mph is realistic for the power and layout. I wonder what prop was used for those tracked flights - 10-9, 10-10 maybe?

The prop on it now is a 11 x 12 but looks altered. Maybe 10 x 12? I can measure. I will post a photo of the wing airfoil, it is razor thin.

It will take some work to make it airworthy. The concealed rudder connection is loose inside the plane. Will have to make a small incision to check that out. Pull and rebuild the engine, new servos, etc.
