I have continued to work on my 3D printed quadcopter. Now I have also created a new baseplate for a hexacopter. It is still using the same wooden arms, motor mounts and landing gears. I have also created a few extra pieces that I needed, mostly mounts for different antennas.
I will probably add more pieces in the future. Please comment if you have any ideas for what I should add or change.

This is a 3D printed quadcopter that I have made. The design is not entirely 3D printed, it uses 15×15 mm wooden spars as motor booms. My idea was to create a modular system to build quadcopters (and maybe other multirotors) using 3D printed parts. I want multicopters that are fast and easy to assemble, modify and upgrade. I also want them to be cheep in material cost, therefore I have tried to keep the weight as low as possible. Right now, one quadcopter frame is slightly below 100grams of plastic.
Right now I have 3D printed motor mounts, landing gears and a center piece as well as a top plate for mounting the battery and all the necessary spacers. The size of the quadcopter is determined by the length of the wood pieces. The quad in the images is a 250 size. I am using wood instead of 3D printed arms it to keep the weight down, I also think it is stronger.
I will continue to experiment with this 3D printed multirotor building system, and hopefully make all the STL-files available for download in the future.
Here is a video of me testing my latest DIY home built mini quadcopter at a local indoor flying meetup. This quadcopter is built entirely out of wood and cowered using Oracover. It is strong and lightweight, designed for fast and agile LOS flying outdoors.
Here I am testing my homebuilt gimbal om my new APM quadcopter. It is a two axes gimbal based on the same Martinez Open Source gimbal controller and the same Quanum 2208 gimbal motors as the first APM quadcopter. I am not happy with how mush of the propellers that are visible in the video. Maybe a solution could be to extend the gimbal and landing gear further down. During this flight I used my 13-inch propellers that I cut down to about 11.5 inches.
There is still a lot of tuning to be done. In the video I fly with propellers that are a little to small (10 inch), this results in sluggish yaw behavior. The 13 inch propellers in the images where to large, they caused the copter to be a little unstable and fly strange due to the low RPM. Currently the camera is hard-mounted, but this copter will carry a gimbal when it is complete. I do have problems with “altitude hold mode” on the APM. Maybe this is because I fly with wrong sized propellers, or there is wind blowing on the sensor.
I am building a new quadcopter frame for my Ardupilot. Hopefully the frame will be lighter and a lot more agile. I went with a more traditional frame-design this time as you can see in the images. This quad will use the same motors and ESCs as my previus APM quad. The GoPro gimbal will be mounted underneath the main plate, and it will be easily detachable if I want to fly without a camera. There will also be possible to attach other things such as a hard-mounted camera or an FPV-module.
Version 2 of my FPV Quadcopter Racing Simulator adds soundeffects. I have also placed a number of gates around the world to fly trough, and added more trees and grass and flowers to make the world more interesting. In this video I fly using an xbox360 controller, but it should work with any controller, including real “RC simulator transmitters”.
In this video I am testing a new gimbal design again. This time I have mounted the gimbal to the fuselage using silicon hoses to reduce motor vibrations. This did remove almost all vibrations. To the APM quadcopter page: APM quadcopter page
