RealFlight Evolution E-flite UMX Waco

RealFlight Evolution E-flite UMX Waco is a model aircraft add-on featuring an updated E-flite UMX WACO biplane. The lightweight, ultra-micro aircraft is designed for indoor flying in gymnasiums and similar large spaces, as well as outdoor use in places such as yards, parks and sports fields.

Aircraft and power

The airframe is made from advanced EPS material and comes factory-assembled in either a fully painted yellow trim scheme or a lighter-weight, unpainted white base version. Its brushless power system has an upgraded outrunner motor compatible with 2S and 3S batteries: 2S 280mAh batteries provide performance similar to the original model, while 3S 300mAh batteries offer more speed and unlimited vertical performance.

Flight systems

The model combines AS3X stabilization, which helps keep flight smooth in windy conditions, with optional-use SAFE Select. When SAFE Select is enabled, pitch and bank angle limits prevent the aircraft from rolling or pitching upside down and restrict excessive climbs and dives. Releasing the sticks with them centered makes the aircraft return to and hold level flight; this can also help keep the wings level during takeoffs and landings.

The control unit includes an ESC and Spektrum receiver, which sends real-time flight battery voltage telemetry to compatible Spektrum AirWare-equipped transmitters.
