P-38L Lightning

P-38L Lightning front - detailP-38L Lightning back - detail

The legendary P-38 “Lightning” revolutionized aviation history in World War II. Designed by a skilled team of engineers led by Clarence Johnson and Hal Hibbard, the P-38 was the only American fighter that was continually produced from before Pearl Harbor in 1941 to after the Japanese surrender in 1945. Over 9,900 P-38s were built, 3,810 of which were the superior P-38L variant. Revered by its foes as the “fork tailed devil”, the P-38 excelled as a fighter, interceptor, reconnaissance platform, long range escort, and as a ground attack aircraft. The aircraft also famously shot down Admiral Isoroku Yamamoto’s aircraft during “Operation Vengeance” on April 18, 1943.
The Flightline RC P-38L wingspan 1600mm is equipped with two 3748 brushless outrunner motors and two 12x7 3-blade counter-rotating propellers for the perfect scale appearance. With the recommended 4S 14.8v 5000mAh (one battery per side or a single battery with your series adapter), the P-38 boasts sufficient power for large consecutive loops and a level top speed of 125 km/u. A durable electronic retractable landing gear, five sequenced servo driven landing gear doors, day-bright LEDs, machine gun details, plastic nose cone and cowls, four flaps, accurate canopy and nacelle shape, and many other scale details. Each rudder is directly controlled by its own servo. The cockpit layout accommodates a wide range of 4S 14.8v Li-Po batteries with ample space for electronics. To ensure a high degree of structural rigidity, the entire model was designed around a special framework of carbon rods and reinforcement points. This framework strengthens the aircraft during high speed maneuvers, while still providing a gentle and forgiving flying behavior.

Modifications

Used different types of weathering techniques to improve the look of this model. First time that I used airbrush techniques. Oracover ironing film on top of the foam to change the look of this model and added D-day stripes. Added my own Decals inktjet printed on Testors White Decal Paper.

Spitfire Mk IX

Spitfire Mk IX front - detailSpitfire Mk IX side -detailSpitfire Mk IX back - detail

The Supermarine Spitfire is one of the most popular warbirds in history. This British single-seat fighter was used famously by the Royal Air Force and the Allies, earning distinction during the Battle of Britain and throughout World War II. Over 20,300 aircraft were produced with more than 24 variants. The Spitfire’s versatility and maneuverability in the hands of skilled pilots made it a lethal weapon against Axis forces. The timeless Spitfire continues to fly in modern times as a tribute to aviation history and military veterans.
FlightLine RC’s 1600mm wingspan Spitfire Mk.IXc is approximately 1/7 scale and an entirely larger beast with all the bells and whistles we’ve come to expect from aircraft in the 1600mm Class. This Spitfire is molded from EPO foam, featuring a scale shape and smooth surface. The main wing is assembled from hollow foam parts and an interlocking plywood and carbon fiber frame, providing lower weight and higher strength than a solid foam wing. The main wing and horizontal tail are attached with screws for very convenient transport, and proper ventilation is also designed to keep the electronics cool. The large battery hatch and removable battery bay floor provides easy access to an organized battery and receiver compartment. Grass capable landing gear with suspension struts and 5mm thick steel pin and metal trunion, scale four panel split flaps, big 16x10 Propeller, 5055-390KV brushless motor and 80A ESC, LED wingtip lights and dorsal signal light, and 17g digital hybrid servos, brass ball links, and nylon hinges on all control surfaces.

P-47D Thunderbolt

P-47D Razorback - detail frontP-47D Razorback - detail back

The Republic P-47 ‘Razorback’ Thunderbolt was an out­standing fighter, both in the bomber ­ escort and ground-attack roles. It was the largest and heaviest single-engined fighter built during WW2 . It was the last in a series of aircraft that began in 1936 with the Seversky P-35 and included the P-43 Lancer in 1940. Common to all these aircraft was their designer, Alexander Kartveli. In the Republic P-47 Thunderbolt he produced an aircraft that brought the formula to fruition and made up for less successful earlier attempts. A total of 15,634 Thunderbolts were built in several versions. The ‘Razorback', as the first models were called by pilots and ground personnel, was employed intensively by the USAAF and RAF.

This is a highly scaled, lightweight RC-controlled model from FMS. The P-47 Razorback 1500mm adds a slew of innovations to a proven platform. Based on the original 1400mm P-47, the 1500mm model features a 99% scaled control surface, landing gear cover, cockpit interiors, plastic cowling, gun turrets, retracted landing gear, and panel lines.The plane's original oil paint has been replaced by water-based paint. It's built with a lighter and larger EPO 52 foam, making the plane lighter, giving it impressive flight performance without weakening the airplane's strength.New CNC-processed shock-absorbed front landing gear with the latest 2016 FMS electric retract. A new KV650 motor with Predator 70A ESC. All servos are now metal gear digital servos.

MPX Fun Cub

Fun Cub front - detail
Fun Cub back - detail

Started flying again with RC planes (after some 20 years) with the Multiplex Fun Cub. One of the first great things about this plane is it’s 55 inch size (1.4m). The wings come off and on in about 2 or 3 minutes.  Simply plug in your servo leads, and screw in the two nylon screws and you’re ready to go.  The plane is very versatile and perfect for just about any field. It takes off in a few feet. Landings are easy with or without using the flaps.

Mods

Changed the look of this plane with Oracover ironing film on top of the foam. Cut more than hundred separate squares of Oracover film. Add extra suspension on the Landing gear. Relocated a Flap Servo to save an RC channel. Lights to fly at evenings or with some fog. Installed Spektrum airspeed, voltage and flight power telemetry.
