Since I started building my quad, using the F450 frame from UnmannedTech, I wanted to make something myself. I have now ordered myself a Shapeoko (an opensource CNC milling machine) and while I wait for it I have started to design myself a new quad frame - opensource of course
The design is to make it out of either glass fibre or carbon fibre board (or maybe aluminium but that would be after the design is complete, if ever!). I love the industrial trellis design to keep weight down but maintain strength. I also want it to be fold-able so I can transport it on my motorbike easily. It will need to have FPV and gimbal mounting as well.
Currently the 3D mockup is being designed in SketcUP so I can see if there seem to be any fundemental issues and to start with the vague design shapes. The motors are 450mm on center from each other (same as my F450 - had to start somewhere ).
I am maintaining it on GitHub if anyone is interested https://github.com/smartroad/OSQ/
