FlightLine B-24 Liberator Olive Drab 2000mm (78") Wingspan - PNP
FlightLine B-24 Liberator Olive Drab 2000mm (78") Wingspan - PNP - FLW401P
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, Motion RC is 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 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. Designed with input from the Collings Foundation, which operates the only flying B-24-J, “Witchcraft”.
Due to the many configurations of the real B-24, the model features modular design to allow each modeler to customize his/her model further. A magnetic nose section allows owners to quickly swap between B-24 variants, the -D (“Greenhouse” nose), and the -J (“Emerson turret” nose), and the Upper Turret on both variants and the Nose Turret on the -J variant can be panned with an optional 9g servo. Steerable tillers are pre-installed, including special provisions to fit FPV cameras in the nose with minimal modification. An internal wooden spine reinforces the bomb bay area, if a modeler chooses to install operating doors. An all new pilot figure sculpt depicts period accurate A-2 crew jacket, radio headset, and iconic “crusher” cap and insignia. Also for the first time at Motion RC, an optional 3D-Printed Cockpit with complete instrument panel, controls, and seats is also available as a separately purchasable upgrade.
If you have your own 3D printer, or have access to one, you can download the STL files directly at this link. (There are 20 total STL files, formatted for 3D printing included in this .ZIP file). We now offer STL files for the nose gear doors. For the left gear door STL file click here. For the right gear door STL file click here.
Despite its very large size, primary assembly of the entire aircraft is completed with only 12 screws; glue is only required for cosmetic details such as antennas and windows. A quick disconnect ribbon wire harness consolidates wiring into a central circuit board inside the fuselage. Each wing is removable with two screws, making this large aircraft extremely easy to transport.
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. The recommended pair of 4s 14.8v 3000-4000mAh lipo batteries can power the aircraft in excess of 110kph/70mph, for 5-10 minutes based on a pilot’s throttle management. We prefer 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.
Each model includes both the -D and -J nose in the box, and includes two decal sets comprising both waterslide and matte vinyl decals. Additional decal sets are available for purchase from our partner, Callie Graphics, at www.callie-graphics.com. A main suspension strut is available as an upgrade for rough runways. With near endless personalization possibilities, the pinnacle of your warbird hangar has arrived -- The FlightLine 2000mm B-24 Liberator!

Flightline B-24 maiden flight
I bought this plane a year ago and finally got around to flying it. Set it up and taxied on my 300' driveway to make sure that it tracked straight. Finaaly got a relatively calm day at our field to fly it. I was surprised at how lively it was in getting airborne. I think that I may reduce the rates slightly so that it isn't so responsive. I was overall pleased with the way it flew and landed. Slowed down more than I expected with the flaps lowered so you have to keep a little power to it until you flare while landing. I'm sure that I will do much better when I've flown it a few more times. I did have a problem initially with setting up the motors and binding it. I called Motion and they couldn't have been any more helpful. I did have a problem with 1 motor after the maiden, was binding. I called Motion and again they go out of their way to help you. They send me a motor to replace the bad one. Excellent service by them at Motion. Can't wait for the snow to melt and get back to the field for my second flight. Thanks MotionRC Team, especially Andrew who I've talked to several times.
Awesome warbird, very scale, always wanted a quad motor bomber. Love it.
Better than expected.
Assembly was straightforward and easy and the way everything is wired really helped simplify the assembly. On the maiden flight I was surprised at how much power was available on takeoff and how quickly it took to the air even without takeoff flaps. At full throttle the aircraft is surprisingly fast and with various throttle changes throughout the flight the batteries seemed to last forever. The use of two batteries really gave me peace of mind because if one battery died I would still have two engines with plenty of power to land on two engines. The aircraft tended to yaw back and forth a bit when I made turns using ailerons and elevator (due to the wingspan being very long compared to the length of the fuselage). Once I stopped being lazy and decided to make coordinated turns by adding rudder inputs, the aircraft turned and flew perfectly. On my first landing I used full flaps and was a bit late on the flare so the aircraft slammed down hard, bounced into the air and came down hard again. I was very glad that I spent the extra money to get the shock absorbing main gear as they absorbed both impacts very well. After that I performed all landings without flaps and the aircraft landed incredibly smooth each time. I discovered that the aircraft slows pretty quickly on landing even without flaps so they are unnecessary unless landing on a very short field. When landing you want to be very conscious about keeping the wings level as a prop (or two) could strike the ground if they aren't pretty level at touch down. Great scale looks and the only thing missing is the ball turret because it would have to retract like on the real aircraft so it won't hit the ground upon landing. A retractable ball turret would add to the weight and the cost of the model and it wouldn't be that noticeable when the aircraft is in the air anyway. I flew the aircraft at my clubs air show this year and it was a huge hit. After the air show I spent a lot of time answering questions from the fans about the aircraft. Overall I give it 5 stars!
good aircraft with some details. the aircraft is made of frigolite. could have been more details.
Excellent model of the full scale "Witchcraft" flown by the Collins Foundation "Wings of Freedom Tour". I applaud Motion Rc for offering these markings as I had the opportunity to fly on it and the B-17 and B-25 with the same markings offered by Motion RC
fussy on landing-tips l to r and breaks props. More flexible material on prop would reduce breakage.

Finally got to fly the B-24 after a year of delays. Plenty of power: No need for full power on take off. Gradually feed power and it will lift off. Added a little right aileron trim an a little up elevator and it was trimmed. A little reluctant to turn with ailerons so on tight turns add a little throttle and also a little rudder. I landed with no flaps: on final held a slight up elevator and controlled the sink rate with the throttle. About a foot above the ground I cut the throttle and it settled in without a bounce. Very pleased.
I pre-ordered my B-24 for a Christmas present for myself. When the plane arrived it was still winter. Unfortunately before I had a chance to fly it I had a spiral fracture of my right. femur. I'm 84 years old so the rehab wasn't like I was twenty years old. I decided today was the day for the maiden flight. I installed the wings, connected the wiring (all the while admiring the ingenuity of the wiring). When I connected the batteries the LED in the receiver, which I had previously binded did not light up or even blink. I disconnected the BEC, plugged in a receiver battery and all was good. I plugged in the power cable with the BEC and checked the voltage out of the BEC. I don't expect Motion RC to warranty after a year and a half so I guess I'm on my own. In 11 days I'll be 85 years old. I'm still giving the Liberator 5 stars because it's deserves them. It will fly this summer. Don't know how many stars to give the function/perform rating. Everything functions beautifully with a receiver battery plugged into the receiver so will give a "good for now and do another review after it fly it.
