The Rutan Model 74 Defiant is a ARF Nitro Gas twin-engine aircraft with the engines in a push-pull configuration.  An aircraft constructed with a push-pull configuration has a mixture of forward-mounted (tractor) propellers and backward-mounted (pusher) propellers.  The advantage that an push-pull configuration provides is the ability to mount two propellers on the aircraft's centreline, thereby avoiding the increased drag that comes with twin wing-mounted engines. It is also easier to fly if one of the two engines fails, as the thrust provided by the remaining engine is symmetrical, unlike a conventional twin-engine aircraft, which will yaw in the direction of the failed engine, and becomes uncontrollable below a certain airspeed, known as Vmc, which varies based on the type of aircraft
