Conversion to quadrotor (parts)

After having struggled to keep the vibration caused by two of the motors on the hexrotor down I decided to convert it to a quad, thus eliminating the two bad motors. Luckily the website that sells my hexrotor frame ( also sells other frame configurations that use the same arms. This means that I am able to convert my hexrotor frame to a quadrotor frame simply by changing the center plates.
Because I was already paying for shipping I decided to pick up several other spare parts along with the body plates.
To complete the conversion I needed to reprogram my CRIUS SE. This was a problem as although I had an FTDI programmer, the FTDI power supply was shorted with the main rail (see First flight). This meant that I would have to reprogram the board via the ISP (in system programming) port. I found a USBasp AVR programmer for sale at and, as with my other purchase, decided to order some additional parts along with it as the shipping was fixed.
