Well, the multiwii sold by HK use ATMEGA32 ... so its impossible to use paparazzi code.
BTW, do you think krooz board expensive ?
Ardupilot is cheap .... PPZ is good.

i made six prototype units each with more than 220 components, and test and calibrate them also with temperature compensation.
Since by our attempt to solder with paste and a oven this results in many shorts under the ICs and sensors.
The second way was to solder the sensors with hot air. This needs more time to solder but less to find errors.
For construction and test my first umarin i need one day for the Tiny1.3 and Twog about 5-6h.
The problem with companies is, that they often want their own copyright of the PCB.
To get the numbers of autopilots large, it may be a solution to port other software on it or the make the hardware full compatible.
For a Paparazzi autopilot with a port of MultiWii sold by Hobby-King will grow the units counts large and the cost low (< 50 Euros).
For a large number also a windows ground station is necessary i think.
For the users those who want to make their on pcb to use the 10dof Imu from Drotek (29Euro) may be a solution.
I had made such a pcb design but i cant get the cad data for eagle. Christope had no time to add the 4 holes in his Yapa design.
To win completion's always special hardware is needed like the Umarin.
