From Jason Wentworth: A Horten IIIB Flying Wing

Chris Strachan in the UK just sent me a set of peanut scale model plans (see the two attached PDF files) of the German Horten IIIb Flying Wing sailplane and its powered Horten IIId motorglider variant.  He got it from his friend Bill Brown, a fellow model builder & flyer, and the plans were drawn by Bob Marchese here in the USA.  (Bob Marchese's plans service is long defunct.)

 

Chris Strachan has tried rubber power, a Gasparin G24 CO2 motor, and Rapier model jet propulsion motors in his Horten IIId model, all with varying levels of success.  His best results so far have been with a Brown A23 CO2 motor.  The Horten IIId plans show a HiLine Micro-4 electric motor installation.

 

The unpowered Horten IIIb model is also small enough to be launched as a parasite boost-glider (or as an Estes Nighthawk-style pop pod boost-glider with a bit of vertical fin area on the pod for yaw stability during powered flight).  The Horten has a much lower sink rate than the Nighthawk, though.

Hey Folks, I took the plans for the Horten III and blew it up to a span of 52". I powered it with a speed 480 e-flite outrunner motor and a 2100 li-poly 3 cell. I also took an 8X6 electric prop and cut it down to 6 1/2. powers the plane nicely. I've flown it six times in 12 to 15 knot winds and have had no problems. It came out to about 16 oz maybe 18oz.I could use a lighter speed control I'm sure.I'm using an e-flight 40 amp. The plane is no slouch for speed !!!! I do alot of fly-bys as the wing looks really cool. I also increased the skid on the bottom and that workrd out real well..If you want know more e-mail me at kencabral@rocketmail.com..laters
