|Wilbur Rubber Powered Free Flight Model|
There appears to be a trend of wanting to relive the past or in my case I feel like I missed out on certain types of model airplane experiences and I want to try them in the present. After meeting Jim O’Reilly at the 2016 Nats who competes in rubber powered events and runs a model plans business, I decided to contact Jim for suggestions of an older model design that I would build. The model I selected was the Wilbur which was designed in the early 1950’s. Besides the excellent plans Jim creates he has partnered with Bob Holman for laser cut short kits. With a short kit the main parts are included and you provide mainly strip and sheet balsa.
Building a model with all the diagonal pieces was not as hard as I thought it would be, but connecting the two sides with more diagonals was more of a challenge. Apparently I did not connect the sides correctly, in my mind I thought the angles should fill the gaps instead of meeting together. The fuselage although very light seems really rigid just the same. How the stabilizer was built with diagonals and straight ribs seemed like overkill. The cut out in the vertical fin where you insert another piece with the grain going at 90 degrees was a clever idea I had not seen before, I assume this is to prevent warping.

|Covering Fuselage With Polyspan|
Folding propeller construction is completely new to me but I purchased a blank from Volare Products for this particular model. The rough shaping and the hinges come done in the blank so it is mainly final shaping. On a model this size there is a ball bearing thrust washer and a shaft bushing needed which I ordered through FAI Model Supply. The fuselage was covered with Polyspan and the rest with Esaki tissue. I was worried how flexible the wing was until I had covered it.

|Band Burner DT|
For a dethermalizer (DT) I am going to try a rather hi-tech new device which is a band burner DT. This is an electronic device that will burn through a small rubber band at the time you set. I plan to report on this more after I have tried it.
