The QuadRanger VTOL is a standard tailplane aircraft based on the Volantex Ranger-Ex that has been retrofitted with a quadcopter system. The Ranger-Ex is an easy to fly FPV platform that is widely available. It is also available from HobbyKing where it is rebranded as the Quanum Observer. The plasic fuselage and 2 meter EPO wing makes it a rugged airframe with a lot of payload capacity.

The VTOL conversion makes the plane a bit heavier (around 3.5kg including LiPo). With this conversion the plane will cruise at approximately 65% throttle. The suggested quad setup provides a thrust of 7.5kg and the airframe can fly with a total weight of around 4.5kg. This leaves enough payload capacity for payloads like FPV gear and cameras.

The conversion is designed to minimize impact on the aerodynamics and provide additional strength minimize wing flexing.
