Focke-Wulf Fw 190A-5
Dave Tomlinson (822 Lakeview Dr., Lancaster PA 17601; email: [email protected]) built this Vailly Aviation Fw 190 with fiberglass fuselage and wood wing and tail kit from Precision Cut Kits.
This Fw 190 spans nearly 91 inches with a Zenoah GT80 twin-cylinder engine for power. Dave’s model uses a Vailly aluminum spinner, functional fan, wheels, and sports a pilot figure. The main gear and tail wheel retracts are from Sierra Precision Components and the three-blade propeller is from Solo Props.
Dave glassed the all wood surfaces with Z-Poxy and painted the model with WarbirdColors acrylic, water-based paint. All vinyl markings are from FASTSIGNS, Inc.

Lambda 4 Electric Ducted Fan
Paul Stahlhuth (3599 Stockwood Way, El Dorado Hills CA 95762; email: [email protected]) is a retired aerospace engineer and member of the El Dorado RC Flyers.
He prefers designing and building over kit or ARF models. His latest design is the Lambda 4 EDF. This is a 38-inch wingspan jet with two booms and an inverted V (Lambda) tail, which weighs 3.5 pounds. It has rudder-vators, ailerons, and a steerable nose wheel with bicycle landing gear and outriggers. It is powered by an E-flite Delta-V 480 fan and Castle Creations ESC with a 2200 mAh battery.

Stuka
Bob Barczynski (140 Running Bear Trail, Fayetteville GA 30214; email: [email protected]) built his Junkers Ju 87 D-5 Stuka from a vintage Royal Products kit given to him by his father.
The sheet balsa is finished with light fiberglass, automotive primer, and Krylon Italian Olive with Peekaboo Blue spray. It is weathered by sanding artist charcoal sticks into a powder and then dry brushed onto the model. It is topped with flat-finish Valspar Clear Protector. The Stuka spans 71 inches with power provided by a Saito .90 with an external fuel pump.
Bob wrote, “I found construction of a true gull wing to be very challenging and actually needed two attempts to get it straight.”

Dragonfly
Jerry Wideman (8755 Heather Dr., Ypsilanti MI 49198) wrote:
“I designed and built this dragonfly in approximately two months. The bug is powered by an O.S. .25 FX engine. It has a 48-inch wingspan and the secondary wings are 22 inches each. The tail is 20 inches long and 10 of it serves as the elevator. Ailerons are on the main wing.
“After the first flight, carbon-fiber rods were added to the secondary wings to keep them from flexing. The model has five flights on it and it flies well.”

Piper L-4
Dave Muchmore (1849 Lititz Pike, Lancaster PA 17601; email: [email protected]) built his Cub after seeing a website mentioned in Model Aviation magazine.
Screen shots from the website were blown up and printed to give Dave two sets of scale plans. The vertical and horizontal control surfaces were hinged with nylon hinges. A significant amount of washout was drawn into the original plans.
Power is supplied by a Magnum .46 turning a 12.25 x 3.75 APC propeller. Control is from an Airtronics radio and five servos. Dave’s Cub spans 65 inches and weighs approximately 5 pounds.

Twin Commander Shrike
Terry Arford (8919 Mercedes Ave., Arleta CA 91331; email: [email protected]) built his Shrike from a Top Notch Product Company kit.
The model spans 57 inches and has fixed gear, two outrunner brushless motors, a Master Airscrew propeller, LiPo batteries, and a Spektrum DX7 radio. Terry modified the airflow tunnel exit for increased airflow through the fuselage and around the ESCs. It is covered with white LighTex on top and dark blue MonoKote on the belly.
Terry airbrushed the striping and it is his own design. The tail numbers, the American flags on the vertical, and the surfboards on the sides beneath the cabin windows were drawn by Terry and are inkjet-printed decals.
Mustang and Fw 190
Louis Goldberg (667 Old Pinson Rd., Jackson TN 38301) built his P-51 from a modified Nitro kit and the Fw 190 is a Global ARF.
The Mustang has flaps and a Super Tigre .75 powers the 13 x 8 propeller.
The Focke-Wulf uses retracts and flaps and an O.S. .91 FX supplies the power.
Robelen Pronto
Randy Meathrell (7636 N. Outlook Ln., Prescott Valley AZ 86315; email: [email protected]) scratch-built this 1970s-era Robelen Pronto.
The Pronto is a three-channel, simple-to-build, low-wing trainer. The model was built using 1/4-inch hardwood dowels on the LE for strength. The original model uses an O.S. Max 20 for power and Randy built it while he was in college in the 1970s. He came across the plans for the Pronto on the Internet near Christmas and decided to build an electric version.
Randy’s model is built exactly like the original and is powered by a Value Hobby GForce G15 brushless outrunner. Randy wrote:
“This motor provides tremendous power and the Pronto will go straight up on takeoff at a 5,000-foot field elevation. The model will loop, roll, spin, snap roll, and fly inverted—all on three channels. The Pronto is even more fun then I remembered!”
