The Velox Revolution is a full-scale aerobatic aircraft produced by Charlie Wolff at Velox Aviation. It was among the first piston-engine aerobatic designs to be produced from a majority of composite airframe parts. The Velox has been in production since the mid-1990’s, and as of 2017, Charlie had completed 10 copies, in both Revolution I (single-place cockpit) and II (dual cockpit) versions.
The Velox is an interesting design subject for an aerobatic model because it’s “right” in the full-scale design, (mid-low wing, low stab, low thrust line) and does not have to be molested much to optimize it as a model.
