RC B-747 airliner

Here is the B-747 I have been working on for like a couple of years on and off. After the design was completed the testing flights went good since we only had to make one! WOW. We never crashed it since it handled fine and was very predictable. It uses four quadcopter engines and you just arrange them so they are counter rotating and cancels out any torque. The B-747 size is; wingspan 42”, length 46” and flying weight 3.0 pounds and that was with a 1400mha 4s battery. We wanted ours to be light weight so it lands slow and easy but you can always put a bigger battery in it. We had to install some lead weight in the very tip of the nose, I think it was close to 1 oz. Aircraft uses 4 channels: throttle, elevator, aileron, rudder. Landing gears are fixed. Flight control surface deflection information and CG information are included in the instructions. Also some printable decals that get cut out and glued on are also included.
The whole aircraft and landing gears are made from PLA and seem to hold up well but are not rated for the grass. The mains usually hold up but the nose gear pulls off when a grass landing occurs. Glue the same pieces back together and it’s ready for more flights! Since this B-747 is a profile design the assembly is quick and easy. Even applying the decals are easy because everything is flat. Just need a flat surface and a straight edge. There are wing assembly tools you 3d print off to hold the wings in the proper position while gluing together, it’s easy. One 1K spool of PLA will build the whole airplane.
So, all STL files and bonus G-code files are included set up for ender 3 printers with 220x220 size beds. Some STL files will need to be placed onto your slicer and mirrored to get the parts for the right side. Directions and setup information files are in PDF format. Enjoy being the captain of your own B-747 !

All printer setup instructions are included in PDF format and use standard PLA material.
