1B-24 LIBERATOR
Iten No.:
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 1/10 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! Operater should have a certain experience, beginners should operate under the guidance of
professional players.
2.Before install, please read through the instructions carefully and operate strictly under instructions.
3.Cause of wrong operation,Freewing and its vendors will not be held responsible for any losses.
4.Model planes’ players must be on the age of 14 years old.
5.This plane used the EPO material with surface spray paint, don’ t use chemical to clean, otherwise it will damage.
6.You should be careful to avoid flying in areas such as public places,high-voltage-intensive areas,near the highway,
near the airport or any other place where laws and regulation clearly prohibit.
7.You cannot fly in bad weather conditions such as thunderstorms,snows....
8.Model plane’s battery, don’t allowed to put in everywhere. Storage must ensure that there is no inflammable
and explosive materials in the round of 2M range.
9.Damaged or scrap battery should be properly recycled, it can’t discard to avoid spontaneous combustion
and fire.
10.In flying field, the waste after flying should be properly handled,it can’t be abandoned or burned.
11.In any case, you must ensure that the throttle is in the low position and transmitter switch on, then it can connect
the lipo-battery in aircraft.
12.Do not try to take planes by hand when flying or slow landing process. You must wait for landing stop, then carry it.

Pull the latch back
and open the cockpit.
Before connecting the battery and receiver for the first time,
please remove the propellers, position the model on a stand
above the ground. and switch on the transmitter power and
make sure the throttle stick is in the lowest position.
After you have programmed your radio transmitter, reinstall the propellers and carefully verify their correct rotation. With the aircraft
level, the uppermost tip of all the propellers rotate inward, toward the fuselage. The stock PNPconfiguration 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, clear the propeller area to avoid personal injury.
We recommend the following LiPo battery:
4S 14.8V 2800mAh ~ 4S 14.8V 4000mAh (2pcs)

Center of Gravity
- Depending on the capacity and weight of your choosen
flight batteries, move the battery forward or backward
to adjust the Center of Gravity.
Correct Center of Gravity ( CG”) is critical for enabling safe aircraft stability and responsive control. Please refer to the”
following CG diagram to adjust your aircraft’s Center of Gravity. This CG has been flight tested 200+ times for your safety.
- If you cannot obtain the recommended CG by
moving the battery to a suitable location, you can
also install a counterweight to achieve correct CG.
However, with the recommended battery size, a
counterweight is not required. We recommend
flying without unnecessary counterweight.

After installed the plane, before flying, we need a fully charged battery and connect to the ESC,then use radio to test
and check that every control surface work properly.

IMPORTANT：
Throttle Calibration
Before your first flight, without the propellers attached, calibrate your ESC pairs and verify that all four motors are
synchronized. Install 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.

Dual Rates
According to our testing experience, use the following parameters to set Aileron/Elevator Rate.
Program your preferred Exponential % in your radio transmitter. We recommend using High Rate for the
first flight, and switching to Low Rate if you desire a lower sensitivity. On successive flights, adjust the
Rates and Expo to suit your preference.

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.
