|Dewey Bird Control Line|
|Wilbur Flying in the Fog|
After the Free Flight Nats was over I wanted to try control line flying again, last fall I was flying an electric powered control line that worked well after initial problems. This year it flew fine but I have been hesitant to try any stunting other than wingovers because it seems rather fragile. So last winter I had ordered a simple ½ A glow powered control line the Sig Dewey Bird. Construction went well but then I was hesitant to install blind nuts because of the challenge it has been for me in the past. This time it went worse in that I got epoxy inside of the threaded area and twisted off a bolt. I tried drilling out the bolt but my drill bit barely scratched the surface. I started asking questions to a free flight listserve group and I received a lot of good suggestions although most were what to do before I twisted the bolt off, like heating the epoxy or plugging the hole before the epoxy. At the local hardware store I bought a cobalt drill bit which did drill through the metal and I tapped it for 2-56.
|Piston and Cylinder Cox Baby Bee .049|
Someone gave me a Cox Baby Bee .049 that would not turn over with a rather large wood propeller. I figured the propeller over heated the engine but in asking questions I found out that people run even larger propellers on reed valve Cox .049 engines in the Texaco event. When I took the engine apart the bottom of the piston that connects to the connecting rod looked like it exploded. From my stash of old engine parts I found another piston and pushed out the old one. After putting the engine back together it ran great after a short time, it will be used in the Dewey Bird. With my electric control line I added tip weight that I never put in, it really helped the tension on the line; for the Dewey Bird I used a nickel for tip weight.
|Model Kit Instructions|
|Furniture Assembly Instructions|
A couple of weeks ago I helped a friend assemble some furniture, it went pretty well for me but I have to believe that having built model airplanes was a real help. I have lots of experience reading directions and diagrams with model airplanes. With so much purchased online being able to assemble anything can save a lot of money compared to paying someone to do it. I found this quote from Business Insider about “spatial reasoning ability” interesting:
“It's no surprise that high verbal and math SAT scores at a young age might predict future success, but when you add a test for spatial reasoning ability to the mix, you get an even better predictor of someone's future accomplishments, creativity, and innovative potential, a recent study found.”
