The Canadian de Havilland Turbo-prop Twin Otter was designed for use as a regional commuter and for other special applications. The plane has a 65-foot wingspan, can carry up to 12 passengers or a load of 4,400 pounds and can operate from short runways. This 1/12-scale design of the Twin Otter makes a great 4-channel model that can be powered by a pair of geared Speed 48- electric motors or small .10-size glow engines. Because the model has a high-lift wing, I decided not to use flaps, but the ailerons are large enough to be used as flaperons if you’re looking for STOL capability. If you go this route, you’ll need to modify the wing for dual-aileron servos and use a radio with flaperon programming. If you’re really into scale, there are lots of websites that can give you information on color schemes and scale detailing.
