Expert model aircraft builder Otto Dieffenbach has a creative array of flying machines in his hangar — a Tardis, Snoopy on his doghouse, R2D2, and more. But none capture the spookiness of the autumn season like his flying witch — a life-size sorceress flying on a broom high in the skies.
Otto debuted this particular build in 2013, with videos of it flying over a bright full moon above the San Diego skyline, and a full build log for those who might want to replicate the craft. The witch largely consists of flat Depron pieces held together with an internal frame, with linkages to control lift (via the cape) and steering (via the broom “bristles”). Propulsion comes from a brushless electric motor with a 10-inch propellor. Flying through the sky, the 3D effect is convincing — Halloween is here.
While you might be tempted to jump in and create your own, be warned that his notes state “This is a difficult build and should not be attempted by a newcomer to the hobby. There is a lot of wood work involved. You may want to find a friend with superior build skills if you are a newcomer.” However, Otto also sells as ready-to-fly version for $1850 on his site.
Otto tells us he’s working on a Mary Poppins build now. Keep your eyes peeled for that soon.
