I have found my pictures that I took during the build of my Quadcopter frame. (I thought I deleted them by mistake)
Here we see that the threaded rods are a bit to long. I ran out of 6mm alloy tube so I could not finish 4 spacers – they are going to be 20mm (the ones in the picture are all 15mm)
20mm is needed to make room for the EDB.
The layers are 95*95mm
The arms are 10*10mm and 300mm long
The cc between mounting holes are 40mm
The threaded rods are M3
Holes to motors are drilled to suit 22-20L and the landing gear
