B-24 Liberator front - detailB-24 Liberator side - detail

The Second World War Bomber Liberator is one of the most recognizable WWII aircraft of all time. Serving in every theater of that global conflict, the B-24 fought to bring its brave crews home through unimaginable danger. With humility and reverence, Flightline is proud to introduce the world’s first foam electric B-24 Liberator, in remembrance of the crews who gave the ultimate sacrifice and those who carry on its memory. The FlightLine B-24 Liberator is approximately 1/16.7 scale, with a 2000mm wingspan and 1230mm length, and is constructed from EPO foam and reinforced with integrated aluminum, carbon fiber, plywood, and plastic structures. The FlightLine B-24 uses four 3530-860kv brushless outrunner motors, 30A ESCs, 9.5 x 7 counter-rotating propellers, and a separate 5A UBEC. A pair of 4s 14.8v 3400 mAh lipo batteries powers the aircraft in of 1000km/h, for 5-10 minutes based on a pilot’s throttle management. Mid-throttle cruising for 7+ minutes of scale-style flying. The outboard motor pair and inboard motor pair are powered by separate flight batteries, allowing for powered landings in the event of one battery losing a cell. A 70mm tall nose wheel and 85mm tall main wheels provide stable operation on grass runways and split flaps aid in low-speed flight and landings.

Modifications
Used different types of Painting, Airbrush, and Weathering Techniques and used Oracover ironing film on top of the foam to change the look of this model. Added 3D printed interiors for the Turrets, Cockpit and Pilots, and additional Gunners. A Bomb space was created and two Bomb Doors were designed and 3D printed. The Top Turret can rotate remotely 360 degrees, and the Front and Back Turret are moving together with the Rudder control. The Bomb Space can contain 4 3D printed WWII Bombs or a Parachute with Soldier or Relief Supplies. Modified landing Gear with other tires. Added Spektrum Airspeed, Temperature ESCs, Flight Voltage, and Power Telemetry. Installed Spektrum 9 Ch with AS3X Gyro technology RX. Used a separate UBEC from Castle Creations and an Optipower Ultraguard battery with fail-safe switch PCB. Safety System with Fuse so the Battery Pair starts working separately when a problem occurs (Short Circuit or a Defective battery Cell). In normal operation, both Battery Packs are keeping the same Voltage. Installed a Sound Module Aspire from MrRCsound with two Dayton Audio DAEX25FHE-4 High-Efficiency Exciters and the B-24 Multi-Engine Sound to maximize the allowable sound pressure to 84 dBA at 7m distance. Added navigation lights and landing lights.

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. The 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 ink-jet printed on Testors White Decal Paper. Added Spektrum Airspeed, voltage, and Flight power telemetry. Put in Spektrum with AS3X technology 9 channel RX. Used a separate UBEC from Castle Creations and an Optipower Ultraguard battery with fail-safe switch PCB. Recently added a MrRCSound Aspire 4.1 Sound Module with Exciters in the two Motor Compartments.

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 provide 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.

Modifications

Used different types of weathering techniques, changed green camouflage color with a splashing technique to change the look of this model. Added instrument panel and a hand-painted pilot inside the cockpit. Modified landing gear with other tires. Added Spektrum airspeed, flight voltage, and power telemetry. Installed Spektrum 9 Ch with AS3X gyro technology RX. Used a separate UBEC from Castle Creations and an Optipower Ultraguard battery with fail-safe switch PCB. Installed a sound module Aspire from MrRCsound with two TT25 transducers in the radiators on the wings and put in the Merlin Rolls Royce sound and maximized the allowable sound pressure to 84 dBA at 7m distance.

A-10 Warthog Thunderbolt II

A-10 Warthog - detail
A-10 Thunderbolt IIAfter three flying seasons, this plane was taken out of service. Due to the limited power of the two EDFs, the length of the longest runway of our field was sometimes not sufficient.

Warbird (Irak and Afghanistan) jet A-10 Warthog Thunderbird II from Freewing with 2×12 blades 64 mm EDF. This is a single-seat, twin turbofan engine, straight wing jet aircraft developed by Fairchild-Republic for the United States Air Force (USAF). Commonly referred to by its nicknames Warthog or Hog.

Modifications

Made a separate central compartment with an access opening for the RX. Applied weathering and improved visibility with red and black wingtips. Put on a bigger landing gear to make this plane suitable for grass fields. Added Spektrum airspeed, temperature ESCs, flight voltage and power telemetry. Installed Spektrum 9 Ch with AS3X gyro technology RX. Modified the ESC bay for better cooling and installed a temperature sensor. Upgraded the 5 blades Freewing EDF units to 64mm 12 blades with outrunner 3300KV motors. Changed all connection screws with bolt and nut connections to easy and reliable dismount and mounting of the wings and the EDF turbines for easy maintenance and transport. Improved the fixation of the elevator pushrod tubes for accuracy and safety.

Aircraft Characteristics after Modification

This Aircraft is put out of service after many flying hours. It made room for the P-38 Lightning “Betty Boop” a two-engine plane also on this Website. The plane was a bit underpowered (only 2x EDF 64mm 12 blades KV3300) and could only take off on our 60m grass runway in ideal circumstances. After recuperation of spare parts, this plane was shredded.
