Sting (oz14344)

About this Plan

The Sting. Radio control sport aerobatic model, for .40 power.

Quote: "The Sting, by Vince Micchia. A gentle aerobatic sport ship that will do the pattern, the Sting tied for second place in the RCM 1979 Design Contest.

Quick and easy is the name of the game today. Quick to build and easy to fly. Well, if that's what you're looktng for, search no more, as the Sting is here at last. This design has been bugging me for about a year now, so the decision was made to put it on paper and try it out. I hope you like itenough to try it yourself. Alter spending some time on the drawing board, the pencil lines were completed at last. The purpose in mind was to keep The Sting as simple as possible and still maintain semi-modern lines.

The airfoil used is the same that was used on the SST 40 (oz8975) which is kiitted by Hobby Shack. The control surfaces of the Sting are generous enough to have full control of the model even at very low speeds. The overall construction of the Sting has been kept simple with no difficult planking or carving. The Sting tips the scales at 5 pounds and, for a .40 powered model with the wing area of over 600 square inches, leaves the power loading in the low numbers.

After spending some time at the local hobby shop, buying up some of the materials needed to start construction, I couldn't wait to get back to the shop to start the Sting. I'm sure many builders have felt the same when starting a new model.

That evening, much to my surprise the fuselage was practically finished. I find one of the best methods of cutting out parts. when building plans, is to trace the pals on tracing paper or velum. Cut the part from the paper leaving 1/8 to 1/4 margin from the part. Cement the paper to the wood with rubber cement, Cut the part out, remove the paper, and wipe the part clean. The rubber cement will peel right off easily.

Two weeks later, working two or three hours an evening, The Sting was finished. So here we sit writing an article of the events that took place, and how the Sting goes together. As of this writing the Sting has been test flown and a few photos taken of it.

The first day we tested the Sting, there was no wind blowing, so the time was ideal. We did a distance check which really wasn't necessary since the receiver had been used before. The K&B 40, with a Top Flite 10/6 prop up front, was started. First off, to get rid of the jitters, the Sting and I did some ground handling. I got it to the far end of the field and made ready for take-off.

I was again surprised in what little time it took for The Sting to get airborne. I would say 25 to 30 feet and The Sting was up and away. After flying it at moderate speed for the usual two or three laps around the flying site, the time had come to put it to work. First a very large loop was tried at full power all the way around. if the wing was going to go. know at the bottom. I also checked for flutter - there was none. Next we did a roll. It rolls well, but you will have to use a little rudder when the wing is vertical on both ends of the roll..."
