The famed B-24 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, FlightLineRC and Motion RC are proud to introduce the world’s first foam electric PNP B-24 Liberator, in

remembrance of the crews who gave the ultimate sacrifice and those who carry on its memory.

The FlightLineRC B-24 is approximately 1/16 scale, with a 2000mm wingspan and 1230mm length. Constructed from

EPO foam and reinforced with integrated aluminum, carbon, and plastic structures, the B-24 delivers the ultimate all

around experience for pilots seeking the ultimate foam PNP bomber replica. A magnetic nose section allows owners to

swap between two B-24 variants, the -D (”Greenhouse” nose), and the -J (”Emerson turret” nose). The Upper Turret on both

variants and the Nose Turret on the -J variant can be panned with an optional servo. Steerable tillers are pre-installed,

including special provisions to fit FPV cameras inside.

The FlightLineRC B-24 uses four 3530-860KV brushless outrunner motors and four 30A ESCs. A quick

disconnect ribbon wire harness consolidates wiring into a central circuit board in the fuselage. The recommended

pair of 4s 14.8V 2800-4000mAh lipo batteries 2pcs can power the aircraft in excess of 110kph/70mph, for 4-10

minutes based on a pilot’s throttle management. The outboard motor pair and inboard motor pair are run from

separate flight batteries, allowing for powered landings in the event of one battery failing. A 70mm tall nose wheel

and 85mm tail main wheels provide stable operation grass runways, and optional suspension struts are available.

Assembly is comprised of only 12 screws and gluing on external details such as antennas.

1. This is not a toy! Operators should have some basic experience. Beginners should operate only under the guidance of a professional

instructor.

2. Before beginning assembly, please read through the instructions and carefully follow them throughout the build.

3. Freewing and it's vendors will not be held responsible for any losses due to improper assembly and operation.

4. Model airplane operators must be at least 14 years of age.

5. This airplane is made of EPO foam material, covered with surface spray paint. Don't use chemicals to clean as it may cause damage.

6. You should avoid flying in areas such as public places, areas with high voltage power lines, nearby highways, airports or in other areas

where laws and regulations clearly prohibit flight.

7. Do not fly in bad weather conditions, including thunderstorms, snow, etc...

8. Lipo batteries should be properly stored in a fire proof container and be kept at a minimum of 2M distance away from flammable or

explosive materials.

9. Damaged or scrap batteries must be properly discharged before disposal or recycling to avoid spontaneous combustion and fire.

10. At the Flying Field, properly dispose of any waste you have created, don't leave or burn your waste.. Ensure that your throttle is in the

low position and that your radio is turned on before connecting the Lipo battery.

11. Before connecting the batteries, make sure your transmitter is powered up, with the correct channel selected and the throttle in the

lowest position. If you have a kill switch, engage it as well.

12. Do not try to catch the airplane while in flight. Do not touch the airplane until it comes to a complete stop and the propellers stop

turning.

PNP Assembly Instructions

Wire Pull-Through Tool Instructions

Our tests show that excessively long servo extension lines increase the risk of poor connections that can lead to servo brown outs or failure, causing accidents during flight. Instead, this kit contains a steel wire that can be used to pull the main wing/elevator and rudder servo wires through the airplane to the battery compartment

Horizontal Stabilizer/Vertical Stabilizer Assembly

As shown in the photo below:

1.Insert the left and right rudder servo cables into the trough of the

horizontal stabilizer, and pull the cables through the gap.

2.Secure the left and right vertical stabilizers to the horizontal stabilizer

with 4 PA3x8 screws.

3.As shown in the photo, bundle the rudder/elevator cables and use the

Wire Pull-Through Tool to feed the cables to the battery compartment.

4.Finally, install the horizontal stabilizer to the fuselage

and secure it with 4 PA3x8 screws.

Before connecting the batteries to the ESC for the first time,

please remove the propellers, position the model on a stand

above the ground. and switch on the transmitter power. Ensure

the throttle stick is in the lowest position. Engage the kill switch if

you have one assigned

After you have programmed your radio transmitter, reinstall the propellers and carefully verify their correct rotation. With the aircraft level, the

uppermost tips of all the propellers should rotate inward, toward the fuselage. The stock PNP configuration assigns the inboard motors to one

flight battery, and the outboard motors to the second flight battery. If one battery fails, the model can be landed immediately on the remaining

two engines flown at full power. Before all flights, ensure all areas forward of the propellers are clear to avoid injury.

Center of Gravity

Correct Center of Gravity (

following CG diagram to adjust your aircraft’s Center of Gravity. This CG has been ﬂight tested 200+ times for your safety.

CG”) is critical for enabling safe stable flight performance and responsive control. Please refer to the

”

- Depending on the capacity and weight of your choosen

ﬂight batteries, move the battery forward or backward to

adjust the Center of Gravity.

- If you cannot obtain the recommended CG by moving the

battery to a suitable location, you can also install a suitable

counterweight to achieve correct CG. However, with the

recommended battery size, a counterweight is not

required. We recommend ﬂying without unnecessary

counterweight.

We recommend the following LiPo batteries:

Servo Direction

A servo or reversed servo is defined as follows: When the servo input signal changes from 1000ųs to 2000ųs, if the servo arm rotates clockwise, it's a positive servo. If it rotates counter clockwise, it's a

reversed servo.

Note: If you choose not to use the factory servos, the servos you choose may be a different size. Use the following chart to ensure that the servos you choose are compatible with this airplane.

Dual Rates

With reference to our Flight Test data, we recommend the following parameters to set the Aileron/

Elevator Rate. Program your preferred Exponential % in your radio transmitter. We recommend using High Rates

for the first flight, and switching to Low Rates if you desire a lower sensitivity. On successive flights, adjust the

Rates and Expo to suit your preference.

IMPORTANT：

Throttle Calibration

Before your first flight, remove the propellers and calibrate your ESC pairs and verify that all four motors are synchronized.

Reinstall the propellers and taxi test the model to check for synchronous thrust.

Flap Mixing and Tips

1 - A Flap-to-Elevator Mix is required to maintain level flight when the flaps are deployed. With 13mm of flaps(Low Rate),

mix 1.5mm of Down Elevator. With 29mm of flaps (High Rate), mix 3mm to Down Elevator.

2 - When flaps are deployed, do not advance the throttle very quickly. The B-24 is intended to be flown as a scale bomber,

with moderate throttle advance. Add rudder input to flatten turns for more scale appearance.

Elevator Neutral Position

1. Before your first flight, mechanically set the Elevator's Neutral Position to 1.5mm Up.

大、小舵参数

中文版中文版

根据我们的测试经验，我们认为，按以下参数来设置大小舵量，将有助于飞行。小舵量

飞机的操纵会笨拙些，大舵量飞机的操纵会灵敏些，我们建议初次飞行使用大舵量起飞，然

后视操纵习惯选用小舵量或者大舵量飞行。

特别注意事项：

前检测：飞行

第一次飞行此产品或者更换遥控器后，必须校准油门，这样才能保持4套动力产生的拉力一致，具体校正方法见

电调说明书。

飞行前设定：

1. 降落开襟翼飞机抬头比较明显，需要混控点降舵才能很好降落，小舵量襟翼需要1.5mm降舵，大舵量襟翼需

要3mm降舵

2. 升降舵调平飞机飞行会有比较明显的低头现象，这样需要1.5-2mm升舵飞机就能够很好的平飞；

3. 放下襟翼飞行时，我们需要较柔和的增加油门，不能瞬间加大油门量，否则会出现飞机突然向下飞行，容易

造成飞机坠毁事故.
