I finished Quadcopter mk IV.
It has the exact same components as Quadcopter mk III.
There are a few differences:
I now used Flyduino base plates instead of my own fabricated from sheet aluminum. The Flyduino base plates are very good and has excellent quality and performance.
One thing I had to change was the distance between mounting holes – I used 50mm and Flyduino uses 40mm.
I also perfected the motor mounts and they are now easier to attach than ever using only 2 screws.
The part list is the same as Quadcopter mk II and III
