I am aware that the Reaper is somewhat larger than say a Desert Hawk but both are flown.
I suppose that because Desert Hawk is Army, it doesn't count
The difference between Reaper and DH3 is H
UGE. With DH3 you pre-program a route and then just punt it airborne and it pretty well flies itself and then crash-lands back near you when it is ready. The X-Box controller that is often seen in Army adverts is for controlling the payload (ie. a small EO sensor) and not for flying the aircraft - the control box is for viewing where the DH3 is and for watching the sensor image. The Reaper on the other hand has a pilot at the controls at all times and is flown either through use of throttle/stick, a pre-planned route or an emergency routing should it lose the satellite link.
Here's DH3's control box...
Here's Reaper's control box...(an ISO container! called an MGCS)...
The pilots for Reaper need a full and current Instrument Rating because they fly under IFR - the DH3 operators (not pilots) do not beacuse the do not!
Enough said???
