Avionics

Controller

Embedded controller: Arduino or clone.

The following as interesting and already in inventory: Arduino Decemilia, Arduino Uno, Arduino Mega 2560, Maple Mini, Maple (Rev5).

Sensors

• This is the initial sensor package:
  • LS20031 GPS
  • Accelerometer (3 axis) also includes magnetometer
  • Barometric Pressure/Temperature Sensor (We might need greater accuracy.)
  • L3G4200D Gyro (3 axis) also has a temp sensor
  • Proximity Sensor

Sensor Type	Nominal Power	Voltage Req	Temp Ranges (C)	Data Pins Required
GPS Module (LS20031)	29.000 mA	3.0 - 4.2 V
Compass & Accelerometer (LSM303DLH)	00.830 mA	2.5 - 3.3 V	???	2 (i2c)
Barometer (MPL115A1)	00.010 mA	2.4 - 5.5 V
3-Axis Gyro (L3G4200D)	06.100 mA	2.4 - 3.6 V	-40 to +85	2 (i2c)
Sonar Range Finder (MB1000)	02.000 mA	2.5 - 5.5 V
Accelerometer (ADXL335)	00.350 mA	1.8 - 3.6 V	-40 + 85	3 (analog)

• still looking for a good altimeter, a replacement for DTED lookup

Aircraft

Airframe

The initial airframe must forgive mediocre piloting. We want docile flight characteristics combined with a rugged air frame.

Try to select a craft with spares to reduce cost of reconstruction.

These are our top candidates:

• Radian Pro -- (YouTube) (Note the Radian Pro has AIL, FLAP, ELV, & RUD the Radian standard has only ELV & RUD only)
• Phoenix Glider Pretty cool name... If the avionics fit into the cockpit I say go for it. (Note that we can add flaps!)
  • Alternate source
• Bixler Looks like a good place to start. Lots of surfaces to control, plenty of room for avionics, and reasonably priced.
• Multiplex Cularis (2.6m) available as kit or RR (Note the Easy Glider Pro, also...)

These are interesting alternatives:

• HobbyKing SkyFun Flying wing. Minimal surfaces.
• Predator Fairly large. Lots of goodness?
  • review great info.
• Reaper cool.
• Van's RV-9 too cool, experimental!
• 3m wingspan big and light
• 4m wing span huge, does not look like 12 ft

Surface Control

• Servos X 4
  • want light ones, but strong enough to control the surfaces, might need to get the craft before we order/change the servos

Comms

• XBee PRO 900 XSC? or...?

Miscellaneous

• Camera?
