[Headline: Joe Eiben’s AT-6]

Profile Scale is an event that makes it difficult to hide features that make the model look too busy. Somehow you have to hide the fuel tank, bellcrank, and pushrod. Add flaps and retracts, and you really have a challenge.
Joe Eiben from Baltimore, Maryland, built his 55-inch wingspan model from his own plans using a plastic model and a three-view. Joe took a canopy designed for a full-body fuselage and reformed it over a balsa mold with a heat gun to flatten it to fit the fuselage. The rubber pilot figure has been filled with epoxy and flattened to fit within the canopy.
The model has flaps, electric retracts, and throttle control. Joe used three-line throttle control and a Spektrum DX6i 2.4 GHz radio was used for the flaps and retracts. The electric retracts are controlled by a toggle switch, while the traditional throttle stick controls the flaps. This allows Joe to slowly lower the flaps and decide how much they are deployed.
The elevator’s pushrod is routed through the profile fuselage and the fuel tank is built into the profile fuselage, making it a clean model. The engine is also recessed into the fuselage.
The take-apart model has the receiver and battery in the wing. Hanger 9 iron-on UltraCote was used for the covering. The scoops, wingtips, and wheel-well cover were airbrushed with latex house paint. The clear coat over the latex paint will make it fuel proof.
Building a model such as this with everything hidden takes more effort, but it is worth it. You can fit quite a bit into the 1-inch-wide fuselage.

Brodak Scale Results
The annual Brodak Fly-In had seven pilots entered in Profile Scale. Bill Avera took top honors with the high static score of 93.5 and first place (185.0 points) with his North American B-25 (see my February 2014 “CL Scale” column).
Joe Eiben had the second-highest static score of 89.5 with his AT-6 and placed fourth with 171.75 points. John Wright took second place scoring 173.0 total points with his Corsair, and Paul Smith took third with his Bearcat at 172.25 points. Second through fourth place was extremely close, with the flight score making the difference.
There were 14 entries in 1/2A Scale, but only 10 pilots were able to complete a flight. Bob Whitney took high static and top honors with his Pond Racer and 111.0 total points. George Marenka and his DC-3 placed second with 108.5 points. Paul Smith took third with 102.75 points with his Skyrocket.
First through third place had the same flight score of 46 points, so the static score determined who took first place.
Fun Scale had nine entries with Ed Mason taking a commanding lead with his DC-6 (again mentioned in my February 2014 column) at 106.25 points. Ed has its four glow engines working well and it made a difference in his flight scores. Getting four glow engines to run in sync and shut down on command requires the right setup and preflight.
Sport Scale had four entries. Richard Schneider placed first with an electric-powered D.H.82 Tigermoth. Ed Mason took second place with his B-17, and Paul Smith was third.

Choose Your Options
Scale is unique because every Scale flight is different. Each pilot chooses the options that are judged during flight. The four mandatory options are takeoff, 10 level laps, realism, and landing. The four mandatory options account for 40 points. The remaining 60 points are options that the pilot chooses based upon what the full-scale aircraft was capable of performing.
Retractable landing gear counts as two options and is judged as an independent maneuver during flight. Retract the gear immediately after takeoff then perform the 10 level laps with the gear up. After the 10 level laps are done, start from normal flight level, slow the model down, bring it to the 6-foot level in front of the judges, and extend the gear. After you pass the judges, retract the gear, and return to the normal flight speed and level flight.
Touch-and-gos count as two options. All other options, including flaps and taxi, count as one. Options tend to be lumped into two categories: mechanical and flight.
Mechanical options include retracts, flaps, bomb drop, and anything else that moves. Flight options include a touch-and-go, taxi, 45° flight, overshoot, and Lazy Eight. Aerobatic options include a wingover, Horizontal Eight, and maybe even a loop, but do not use these if the full-scale aircraft was incapable of performing them.

Upcoming CL Scale Contests
• NASA Scale Classic: Muncie, Indiana, October 3-5
• Airstormers Fun Scale (Florida Control Line Championships): Indiantown, Florida, October 12 (call the CD for club Fun Scale rules)
• Scale XVII: Phoenix, Arizona, October 25-26

I welcome contest reports, upcoming contest flyers, pictures, and any projects you are building and flying. It’s time to start that new project and get ready for next year.
Look for the new rules to be in place for 2015, depending on how the AMA Scale Contest Board voted on the current set of rule proposals.
