Build Video

My build tutorial video for this 321 Airliner. If you watch this video, you will see that I actually overloaded the wire, which caused the wires to melt and the airliner to crash. I rebuilt it, so be sure to check out that video, too. I showed how I fixed it and how you can be sure to avoid this issue yourself.

Easy to build and fun to fly!

The 3D printed 321 is a plane that I designed, based off the Airbus A321. This airplane uses 2 EDF jet motors, has a 2m wingspan, and a RTF weight of 3,360grams. It so true to scale - it even flies like an airliner! It is fast and stable; a reliable airplane that would be great for a beginner flier.

Getting Started

This plane requires a minimum build plate volume of 220x220x250. The fuselage prints are 230mm tall.

My favorite work-horse printer, that I have printed many airplanes with and have run for 1,000+ hours is this one! Check out my Amazon Shop to get a shopping list of items you'll need for this plane.

Jet engines, and Sharklet Wingtips

To keep the scale look of the 321, I decided to use two 70mm EDF jets for this plane. They were the first EDF motors I have ever flown on and they were great. They really add to how awesome this plane looks, and sound of the EDFs is next level for RC planes. I ended up modeling the nacelles of this 321 to the older model of Airbus' engines the V2530.

I did end up going with the more modern sharklet wingtip, however. For those that might not be very familiar with airliners, the sharklet wingtip is what makes identifying the make/model of this airliner difficult. Older Airbus planes typically feature a fence winglet, while Boeing typically features this style of wingtip.

Fixed Landing Gear

I went with a fixed, gear down landing gear for this plane. This helps to keep cost down, keep the build simple, and also allows for one less channel on the transmitter - which was a limitation for me at the time of this design. It is something I may re-design and offer as an add-on in the future.

Easy to access, Less Downtime

I used eight 5x3x10mm magnets to make the hatch easy to open and close. This makes switching out batteries a quick process. A slightly oversized built-in battery tray fits your perfect battery set up; be that 2 smaller batteries, a larger battery or use my set up - 4S 5200mah lipo battery.

Optimizing Thrust

Integrated thrust tubes. I designed the cowl to have an interchangeable tail section to customize the performance of your EDF. I flew my plane with the 90% FSA tail pipe, the 80% will have more speed and less thrust. You can leave this section off completely to get more thrust and less speed. The 80% is a more scale look.

You're ready to build!

Thank you for deciding to build the 321! It is an awesome plane, I know you are going to have fun with it.

Make sure you check out my Build Tutorial, in the description you will find a complete parts list for building and assembly. 

Happy printing! See you on the next build.
