Vickers Wellington as UAV
Bi-motor airplane serving as test platform for FLEXIPILOT.
Used for testing single-engine failures and tuning.
Elevator, differential ailerons, no rudder.

Endurance 50min with one battery.
Cruise speed 50km/h.
Shown loiters at low altitude since at typical cruise altitude of 200m it is almost impossible to track a flying object on the sky with zoomed camera.
The plane is a custom construction, only one in existence in this scale and make (bought on a polish web auction, made by experienced RC modellers from Gdansk, Poland, refitted with autopilot by me).
The weather was a little bit windy, pity it didn't looked as majestic as usually - a few nervous autopilot reactions were inevitable trying to hold constant circle patter over ground.

Why all this? Because it can be done. Testing is the best thing.
