Muncie July 11-12

Last two days of the Nats were pretty windy.   I was told that the rest were worse.

1/2A Texaco DeBolt Airfolier Flying Report




We just got back from flying this evening at Plum Brook. Made three flights with the Airfoiler. Added a one ounce weight to the nose and down and right thrust. The model responded better in the climb out, but I had to add down elevator in the breezy winds aloft. Stu was also right. Plan to increase the positive incidence in the stab.
Add about I/32 plywood shim under the leading edge.
All in all I was able to fly the Airfoiler a lot better tonight.

Back at Plum Brook Today











Hi Guys,
We are back flying R/C at Plum Brook after two and a half years since we were removed from flying there by a young, dumb
NASA caretaker. He was so dumb he was replaced. His replacement reinstated our club to again fly at Plum Brook.
I was making touch and goes with my Sonic Cruiser designed by Hal DeBolt in 1961. Stu Warner took the photos with my cheap Nikon digital camera.
Also flew my 1/2A Airfoiler which Hal DeBolt designed. Hal used seven degrees incidence in the wing and five degrees of positive incidence in the stab. He thought this would eliminate down-thrust for the engine. Hal designed the model for a glow 35 engine. The set up did not work for the 1/2A Texaco version. I installed two washers behind the engine and today the model under power indicated it will require some more down thrust. The model also stalled in the glide. Stu told be to remove some of the incidence in the wing.
I am thinking of adding nose weight; it is easier to add weight. The color scheme is hard to see in a blue sky.
The model has a single, retracting landing gear actuated by a rubber band just like the original.
That Is It For Now.

Sonic Cruiser completed!





Hi Guys,
I finally finished the deBolt Sonic Cruiser.
DeBolt had a novel way to turn the tail wheel less than the rudder. Back in 1961 the control system used reeds or escapements to move things. The photos show debolts system for the tail wheel and the rudder. pretty neat.
The model weighed in on the scale my mother used to weigh me over three quarter of a century ago; the model weighs five pounds three ounces. I worked for NACA and NASA for over one quarter of a century and I can vouch for the accuracy of the scale and it is close enough for Space Craft.
The fancy S or Z was taken off the plans of the Sonic Cruiser.
That's It!
