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).

  • 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!)
  • 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:

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
