This week I was concentrated on the frame of the quadcopter.
I drilled the 4 arms for the mounting of the motors and for fixing the cross.
The motor fixture is drilled for a M3 screw, so I adopted for all the frame the same screws: 12 screws M3 of 30mm.
Note: To be sure that I can remount the arms always on the same position I mark the cross and the arms with a cutter.
- Bar: 5.90 EUR
- Cross: 5.40 EUR
- Screws: 0.8 EUR (25pz)
