Troy's 3D Printed RC AL21 Airliner

cults3d

This is a 3D printed Airliner I designed to be light wight and fly on two 70mm EDFs. This Plane NOW FITS ENDER 3 Build Volume required is 220x220x250. The fuselage parts are 230mm tall. RTF weight: 3,360 grams Wingspan: 1.6m Length: 2m Print time: 220hrs 2kg of PLA I have a full step by step assemble video on my YouTube channel. https://www.youtube.com/watch?v=0YSXmKaWG-M CG set 6in or 152mm from leading edge of Wing1. Here is a link with time stamp how to set CG: https://youtu.be/EvDbhInfS2c?t=492 This plane does not have flaps or retracts to save on weight and keep the build process simple and easy. Also to keep cost down a bit. Use 1mm Carbon fiber rods cut to 18mm for alignment of the fuselage parts do not glue them it makes it harder to get the parts together. The battery door uses 8x 5mmx3mmx10mm magnets. 8mm Carbon tubes (Wing) 2x 19in and 2x 18in the 19in goes in the front. Nose gear uses a small section of 6mm carbon tube and the Main gear both use a small section of 8mm carbon fiber tube. Use 2x8 mm screw to attach servo covers and engine cover. I modified two parts to make this build fit on an ender 3 build plate. Wing Section 1 is cut into two parts use 3 sections of 1mm carbon rods to align Wing1A to Wing1B. I also needed to cut the Mount bracket for the EDF. It is now in 4 sections to fit the smaller build plate. Glue together as shown in picture for the Ender 3 assembly Guide. If you have a larger build volume such as 245x245x260 you can print the original Wing1 and Motor mount to allow less assembly.
