777-200/300
This is my 3D printed 777 airliner I designed to be ultra-lightweight, ultra-scale, and small enough to be easily flown indoors. So easy to print and can be printed on some of the smallest 3D printers on the market. Your new favorite scale model! Minimum Build Volume required is 180x180x180. RTF weight: 68g for the 200 version and 70g for the 300 LWPLA ONLY Wingspan: 500mm Length: 530mm for the 200 version and 610mm for the 300 I have a full step by step assemble video on my YouTube channel.

Build Video
This 3D printed micro 777 was something I've wanted to try to design for a while now. Pushing the limits of just how small a 3D printed airplane can be, in order to have it fly well AND be scale is one of my favorite things about this hobby. This 777 plane has hundreds of hours into the design work in it, so many tests and checks of every aspect within the plane and the parts to improve both their performance and weight. The result is this: an ultra-scale, ultra-lightweight RC plane that is going to both fly great, and have a super cool, eye-catching look. Coming in at less than70g RTF, this plane is best flown on a calm day or would be a great choice for your next indoor fly-in. The files come included with a 3D printable stand that you can use while you're building this plane and afterwards as a display stand for your plane. I designed this plane to include the two most common variants, the 200 and 300 version both are also included in the files. This is going to be a really fun plane to build, fun to fly and you're going to be amazed at how lightweight it is RTF.
Customize Your Plane
There are more operational 300's out there than 200's, but I always enjoy the option to customize a plane to my preference and thought you might also. It's also so easy to extend. I purposefully made the wing root attach only to the center section of the fuselage, so all you'll have to do is add two additional fuselage pieces to extend the plane to the 300 version. I include a 3D printable "Air Canada" outline guide for creating the tail livery. I also include a 3D printable outline guide for the bottom, so you can achieve a perfectly even "belly" paint across the bottom.
Ultra micro Electronics
Finding electronics small enough to fit in this plane, that are powerful enough and compact enough to fit the space required, can be an entire challenge within itself. The biggest design challenge was the nacelles, which took multiple design phases. Clearances for the props and the inner walls of the nacelles seems really simple, but took tons of design work to optimize weight and structure. The motor mounts and engine pylons were also structurally improved in order for them to with stand holding the weight of electronics inside and the impact of takeoff and landing on the nacelles. The engine inlet airflow was something I quickly learned was critical to improving thrust performance and where tons of power is either gained or lost. It was so satisfying finding solutions to all these challenges, and the result was so worth the effort. It was also important to me to keep this plane brushless: more power and efficiency, longer run time, quieter, and (most importantly) cool-factor.
Flap system
One of my favorite design features of this 777 plane is the connection method I used within the flap system. Airliners have a high aspect ratio to their wings which means that it is crucial for this RC airliner to have flaps in order to achieve flight speeds slow enough for indoor flight. Keeping the scale look of the 777 is also so important to me, so I created an inboard and outboard flap system that uses only 1 servo to control both flaps. To do this, I used a TPU connection tab that is only glued to the inboard flap and it freely slides in/out of the outboard as the flaps are extended or retracted.
Getting Started
This plane requires a minimum build plate volume of 180x180x180.
I wanted to design a plane small enough to fit on two of the smallest printers on the market - The Bambu Lab A1 Mini and the Prusa Mini.
