The weather is terrible for flying. So the next best thing is to build a model. The YO - HO was designed by A.J. Phillips and plans are in the October 1955 Flying Models.
The model will be a gift for Tom Ryan and his four young friends he takes to the AMA Nats every year.
Of course there will be a lot of checkerboard tissue , which Tom gave me, on the YO - HO.
Covering is about to start. Photos of the completed covered model to follow.

I think that design the fellow is building for you and your boys was designed by Art Phillips of the "Galeville Gang" !! Art passed away a couple of years back but he surely was a "Pisser" Love to all
I bought an aluminum 2-1/4" TruTurn spinner for use on the Sailplane's McCoy 60. I sent the spinner nut to Bob Beecroft in California for some machining modification. The stock spinner nut is shown in the upper part of the picture below. As you can see, Bob machined part of the hex down as shown in the lower part of the picture below and made a special prop washer to fit it.
Woody Bartelt made a special keyed prop drive spool that was only 0.27" thick as shown below, which was required to properly position the 12 X 4 APC prop relative to the front of the Sailplane's cowl.
This shows these three machined parts on the shaft of the McCoy 60 along with the TruTurn spinner back plate. This picture shows the machined spinner nut tightened down on the 12 X 4 APC prop.
