C/LStunt T
his month I would like to feature six models seen at the 2013 AMA US Nationals in Muncie. They kind of just caught my eye, and I wanted each builder and flyer to say something about his model and his power setup. You will find different skill level Stunt models and a full variety of powerplants. I hope you enjoy the selection. First up is Jason Greer and his Paul Walker Impact. Last year Jason had a Bill Werwage USA-1, but he decided to switch camps and take on Paul’s design this summer. “I built my Impact directly from the origi- nal plans, available from FLYING MODELS (CF856, 5/91). I used a Bob Hunt geodetic lost foam system for the wing construction. The fuselage internal construction was mod- ified for the electric installation. The finish is a combination of MonoKote, UltraCote, and Rust-Oleum Painters Touch on the wheel pants.
“The power system I’m using consists of
the following: a Scorpion 3026 710 Kv motor, Jeti Spin 66 ESC (available from Igor Burg- er), Igor Burger active timer with accelerom- eter, Thunder Power 5-cell 2700 G6 25c bat- tery, APC 13–4.5 EP F2B version prop, and an E-flite 2-inch aluminum electric spinner. “The flying weight, with the battery in- stalled, is 54 ounces. I am flying on 67-foot 0.015 braided lines with a lap time of 5.4 seconds. I use between 1800 and 1900 mAh during a 5 minute, 20 second flight. This has been a good combination for me this summer.”
Next up is Frank Williams with his T.
Gazer or David Fitzgerald’s Thunder Gazer. “After a couple of years experimenting
with electric Stunt, I decided to go back and touch base with a tuned piped system, just as a comparison. The plane I selected was the RSM Thunder Gazer kit. This plane is designed as a take-apart plane, with a re-
movable one-piece wing, a removable stab and elevator, and removable aft fuselage. “The take-apart features don’t add appre- ciably to the weight of the plane and do pro- vide an extra degree of adjustability that you don’t get with a “one-piece” plane. The kit was excellent, the design is sound, and the performance of the plane is outstanding. “My T. Gazer is powered with a PA .75 and an ES Composites tuned pipe. The prop is a Mejzlik 3-blade 12–4.25. The transparent yellow covering is SolarTex, and the other colors are K&B epoxy. The final weight of the plane was about 68 ounces, which might seem a bit high for the 630+ square inches of wing area, but the airfoil is a really superb design and carries the weight perfectly, de- livering some of the best vertical eights and hourglasses I’ve ever done. The vortex gen- erators (VGs) on the wing and stab help with keeping the airflow attached and uniform
over the surfaces. VGs were first used by P.J. Roland of Australia for flow control and to provide more uniform maneuvers and are being used by numerous flyers now.” Dave Trible sent this information on his Desperado: “It was designed most specifical- ly to best suit the power of the RO-Jett .61 and similar engines. It was downsized from my previous designs for better wind pene- tration and power loading. It also incorpo- rates design features to better handle wind and turbulence such as ‘V’ wing tips and a better mix in fuselage side area distribution fore/aft of the tether point. The latest ver- sions are being set up for the RO-Jett .76 and PA .75 for yet more boost and drive through maneuvers, making it a true ‘point and shoot’ airplane.
“There are three principal versions: (1) the Standard, with a 57-inch span and 650 square inches of area; (2) the 59-inch Hi Lift

Jason Greer brought his skills to the Advanced Class at the US AMA Nats in Muncie and placed at the top of the event with his Impact. Text gives more information on his combination.
Frank Williams always has an interesting and different model and powerplant at the Nats, and this summer was no exception. With his
T.Gazer (above left), Frank proved he can move from different combinations and still do well at the
50
Muncie Nats. Dave Trible is from the Kansas City area and is a constant contestant at the Nats and the Team Trials. Dave’s Desperado (above right) was designed most specifically to best suit the power of the RO-Jett .61.
