How we train the swashplate.	Pilot & copter strike a pose.	The flight computer is 600Mhz & yes, she uses all of them.	The best performing arrangement of the IMU.	Complete package with latest IMU and 4Hz GPS placement.
A fully integrated 4 Hz uBlox 5 GPS module from Procerus greatly improved navigation.	The uBlox 5 is simple to integrate, requiring no shielding or antenna amplification.	Hovering under uBlox 5 control is much more stable in almost any wind.	Hovering near Moffet field.	Higher dynamic range achieved by stacking images from auto hover.
Ground based version uses a hacked 72Mhz transmitter.	Groundstation for ground based autopilot.	Ground based autopilot hovering.	Ground station & copter.	Breakout box for ground based autopilot.
