Test Flight

Used the Radian Pro platform and braved the cold.  Actually, the weather was above average (warmer) for this time of year.  The problem is that the same system that warms the air also makes it very windy (50 km/hr gusts)

After a few failed launches I decided to turn on stabilization to steady the aircraft during the launch phase.  It stayed level so the roll control worked. However, the pitch control had a large gain and the plane "porpoised".  At that point I turned off the stabilization and of course the plane pitched and crashed.

It will need some minor repairs but should be able to test again soon.  Will try again with reduced pitch gain.

Noise Solutions - update to "Reliable Readings"

Made some headway with noise problems:

- Noise on optical H readings
Used a sort and median technique
Old Vaio   arduino\read_optical2

I figured we could use the same technique for reading radio channels but the code overwhelmed the Arduino when I used it for 2 channels.  Instead..

- Jitter when reading radio channels
Used averaging and pulsein timeout
Old Vaio  arduino\servoardu_04

Easystar mod

Use Easyglider wings on Easystar.  Stabilize using ailerons and elevator.

Control from Processing

Could use signals sent from Processing to Trainer Jack on RC Transmitter based on GPS and/or IMU data

IMU health

ArduIMU may become dis-oriented during takeoff. 

You could include code which uses gyro readings while the IMU health is in an error state

iPhone App

IDEA:

iPhone app to give flight guidance for RC plane landing

Reliable readings

Got good H readings from Optical Sensor

Arduino\sensor_noise_filter02

Update Feb 17
- Possibly use this to smooth Channel readings for "nudge"
