Cut Pieces
Measurement Units: For this guide I will be using metric measurements because the materials I used are in metric dimensions. If you are using materials in U.S. dimensions, use the second measurement number. e.g. 100mm/3.75″
Cutting Carbon Fiber
Scout’s airframe is constructed entirely from carbon fiber. Cutting carbon fiber is messy. The carbon dust gets everywhere. The dust is also bad for your lungs. When cutting carbon fiber, wear a face mask and eye protection and work in a well ventilated area.
To cut carbon fiber I used a Dremel mounted to a router table and use a 1/8″ carbide cutting bit. Alternatively, you could also us a cutting wheel instead. You could cut the carbon fiber freehand but I found the router table gave more precise cuts.
Make Airframe Plates
Take the sheet of Carbon Fiber and cut five 100mm/3.75″ Squares.
Take the vibration foam and cut a piece to the size of the ArduPilot Mega.
Cut Arms
Take the 10.5mmx750mm square tube and cut four 180mm /7″ tubes for the arms
Make Motor Mount Plates
In order to mount the motors to the square tube we need to make 4 mounts out of the carbon fiber sheet.
Cut four 45mm/1.75″ squares
Take one of the cross plate that came with the motors and place it’s center hole to the top center of the 45mm/1.75″ square.
Cut and shape the carbon fiber square in the shape of a Y. Use cross plate as a template for shaping motor mount
The end motor mount should be shaped as a Y
I thin you might have forgotten to put in the dimensions for the arms of the ScoutUAV. What are they?
The arm lengths are under Make Airframe Plates. I will move this to it’s own section.
The arms are the square tubing. They are cut to 7″
Can you recommend good CAD software in which to design the frame? I don’t have a CNC router so want to create a CAD diagram then send it off to get the pieces cut for me.
The two CAD software that I recommend are Vcarve Pro and Vectorworks Designer. Vcarve is PC only and is very easy to use. Vectorworks is alot better at keeping track of part libraries. It also works on both Mac and PC. There is also a free education version of the software.
