Modifications
Used Oracover ironing film on top of the foam to change the look of this model. Improved the smoothness of the wing edges and surfaces. Installed a Spektrum 9 Ch with AS3X gyro technology RX (3-gyro rate mode implemented) and voltage telemetry with voice alarm on the TX. Modified the canopy to contain the Spektrum Telemetry Vario and Altitude meter (voice and sound status in TX), Airspeed meter, Battery Voltage, Receiver Voltage, and Antenna performance (A, B, L, Lost frames, and Holds) for data logging in the TX. Configured 5 flight modes and 3 extra switchable mixes (Due to the software limitations of the AS3X receiver I had to use the Flaperon setting in the Receiver and 10 extra mixes in de Transmitter). A Take Off Mode (elevator a bit up), a Landing Mode (split throttle >50% a motor curve with Elevator compensation, <50% a Crow -Butterfly- setup with Elevator compensation), a Cruise Mode (with main trim settings) a Thermal Mode (the 4 flap surfaces a bit down -camber- and a relative Elevation trim), a Speed Mode (the 4 wing Surfaces a bit up -Reflex- and relative Elevation trim) and extra mixes for Full Span Ailerons (Aileron to flap mix), an Aileron to Rudder mix for more turn Coordination (easy to overrule manually) and Snap Flaps (some Elevator to Flap mix in Thermal mode).
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.
I bought this plane secondhand and modified it but after one flying season, this plane was taken out of service to make room for 3D printed airplanes. The Trojan was a good flyer but had a lot of problems with a weak nose wheel retract. I recovered most electronics as spare parts for my other FMS planes.
The North American Aviation T-28 Trojan is a piston-engined military trainer aircraft used by the United States Air Force and the United States Navy beginning in the 1950s. Besides its use as a trainer, the T-28 was successfully employed as a counter-insurgency aircraft, primarily during the Vietnam War. It has continued in civilian use as an aerobatics and Warbird performer. The FMS 1400mm T-28 Yellow Navy Trojan V4 is a warbird with gentle flight characteristics and can be used as an RC-trainer plane. Equipped with shock-absorbing oleo struts, servo less retractable landing gear, working full-size flaps, bright LED navigation lights, scale details like chrome spinner and landing gear doors, secure ball links on pushrods, the multi-wire connector allows quick disconnect of wires for easy wing removal.

Oracover ironing film on top of the foam to change the look of the model. .Added my own Decals ink-jet printed on Testors White Decal Paper. Finished with a gloss IR and water-resistant varnish. Added a Spektrum Airspeed pitot-tube, voltage, and Flight power telemetry. Put in a Spektrum 7 channel RX with AS3X technology. Used a separate UBEC from Castle Creations and an Optipower Ultraguard battery with fail-safe switch PCB.
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.

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.
After more than three flying seasons, this plane crashed at the beginning of 2020, due to elevator servo disfunction. Because there was a lot of wind and the crash occurred in a field about 150 m from the runway in an allowed flying area a fire destroyed it almost completely. Because this was one of my favorites I will probably configure a new one out of spare parts for season 2021.
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-engine 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.

Second World War Bomber B-17G based on the silver version 2 from HobbyKing with a 1.85 m span. This plane is called “Little Ukkie” and is based on “Chuckie” and “The Short Arm” both planes witch flew In England 1944 with the 486th Bomb Group from the eight Air force, This aluminum colored plane with the Victory sign on the wings bombed strategic sites in Germany and in northern France before D-Day, and after 6 June 1944. The 486th Bomb Group is part of the 834th Bomb Squadron and lost no aircraft or personnel on its first 100 missions. Probably because the allies reached total air superiority over Europe middle of 1944.

I am using a Spektrum DX9 Black Edition Transmitter in mode 2. The DX9 possesses a number of class-leading features. Easy programming, 250 models. The centerpiece is its incredibly advanced voice and vibration alert system.
I am using the AR9350 9 channel as RX. This is a new generation of Spektrum™ AS3X® with Artificial 3-aXis stabilization. The AS3X System works behind the scenes to stabilize an airplane in whatever attitude you command. A. small aircraft behaves like a bigger one and can the more wind influence. This multiLink receiver gives you the protection of as main receiver connected to two satellite receivers. By mounting the smaller satellite receivers away from the main receiver in different orientations, the odds of all of them experiencing signal reflection at the same time are reduced to a statistical impossibility.
This RX has built-in Telemetry capability. This telemetry module keeps tabs on the quality of the signal coming to the receiver and send this information back to the transmitter where it is represented on the LCD screen and logged o the SD card.
I am using a Flight Pack Energy Sensor is designed to measure battery capacity used. By measuring the current the sensor determines how much capacity has been used by your electric power system. This is more accurate than a voltage sensor. Every 60 secs the TX-voice gives the used capacity. When the capacity of the battery is 30% the TX gives a repeating audio alarm you have to clear (push clear button). After this alarm, you have enough capacity to perform a safe landing (if necessary one go-around).
I am using an airspeed sensor (a pitot tube-based pressure measurement which measures airspeed from approximately 20 km/h to 300 km/h. I am using a switch to get the TX-voice telling me the actual speed at the moment I like to know this information. But more important is a vibration alarm when airspeed drops within a safe zone just above stall speed. This is a very good landing aid. Try to stay just above this alarm until you are about 1m above and at the beginning edge of the landing strip. Flare at stall speed when the plane is maximum 50 cm above the field and gentle land the plane and let the plane slow down on the airstrip or the grass field.
Offline, all telemetry data logged on the SD card can be viewed and analyzed on a Windows PC with the Spektrum Telemetry viewer. Some examples are added to the Spektrum photo link on this page.
What makes the best Warbird for grass landing? Something with bigger and particularly sturdy wheels/landing gear. The Eflite P-47D is a tail dragger and with the factory retracts and stock wheels, nose overs are occurring on take off and landings, especially when the grass is not short. A good thing is, the landing gear is wide and there are possibilities to modify the landing gear to improve stability and take flying precautions to successfully take off and land like a scale plane, also on a grass field.
I have exchanged the 2,5″ (5 cm) wheels with Dubro 3″ (7,5 cm) lightweight wheels. It’s possible to retract these wheels. They fit the openings in the wings. Use a copper bus 4-3 mm to adjust the inner diameter of the wheels. Grind away some plastic at one side of the wheel to fit the wide of the wheel on the landing gear.
I change the inclination of the landing gear to use longer bolts and spacers. The wheels are now 2 cm more to the nose of the plane. This makes a real difference.
Take off with Flaps 1/4 out. Give full elevator up before gently apply throttle to get the plane moving. Apply full throttle only when the plane is already rolling through the grass.Take off with a gentle slope. Retract the landing gear when the plane is airborne. Flaps up when leveling the plane.
Landing with maximum 1/2 flaps deployed, and with a relative fast final approach. (approx. 45-50 km/h). Start losing speed when you are 1m above and at the edge of the grass landing field. Flare when the plane is 50 cm above the field, but keep 10% -15% throttle so air keeps flowing over the wings and the plane will not tip over. Retract the flaps when you have landed. If you like to taxi, don’t stop the plane first on the grass field. Always taxi with full elevator up and flaps retracted.
In daylight, you can improve the visibility of an aircraft by using different colors or patterns on top of the wing versus the bottom of the wing. But when sunlight is limited in the morning, in the evening, when it is heavy clouded or there is some fog all colors faint and become gray or black.
Because the battery for the Fun Cub is 3S you can use the balancer connector to get approximately 12 Volts. led strips are available in multiple colors. I have used short strips with 6 Led green, red, and white to create navigation lights left, right, and in for of the wings. The cables are hidden in the wing with a small cut in the foam and can follow the main spar. Central you can use some simple connectors so you can keep the wings removable. You can cover the electrical wiring with a transparent white tape.
Finally, you have to protect electrical connections and the led strips against humidity. I have used a transparent shrinking tube and used a plastic coating spray from Kontakt Chemie to cover the PCB components.
