BalsaUSA's .40 "Taube" E-Convert

This is an E-Convert of the Balsa USA .40 size “Taube” (The German word for “dove”).  The Taube’s wing design is based on the Zanonia tree seed pod, which drifts through the air for great distances and was built from 1911-1915 in several different forms.  At the outbreak of WWI, it was already four years old but was pressed into service as a surveillance aircraft and also as a trainer.  Something interesting about the Taube: it employed “wing warping” on the wings and horizontal stabilizer instead of the hinged elevator and ailerons.  This model is a “stand-off” scale version set up for elevator, rudder and throttle control only.  It flies quite well actually and is more like a giant gentle park-flyer.  The construction is pretty straight forward built-up balsa.  I did change a few things though…  I did away with the sheeted fuselage aft of the wing and went with a built-up structure.  I also built up the elevator as well.  I added a bit more wire work to the landing gear, filled in the engine hole, and constructed a dummy replica Mercedes six cylinder engine.  The dummy engine is actually held on with strong magnets incase of a nose over so it can detach.  I built a replica propeller from a standard wood “Zinger” prop and re-stained it.  The wheels are Top-Flight 4” spoked wheels from Tower Hobbies and really help in tall grass.  I did add a tail wheel in place of the slid for better ground handling and the control surfaces are rigged with pull-pull servo control cables.  The front half of the fuselage is painted a flat olive drab and the rest is covered with Coverite iron-on cloth covering and left the antique color.  Boy, that is nice stuff to work with – a real delight!.

The model flies beautifully; slow and scale like and is a real sight in the air!  There are no nasty tendencies in the turns and landing is like silk.  If you are into the scale appearance and slow majestic flying, I highly recommend you take a look at this one.  With the E-Flight Power46 motor it is pretty over-powered and will cruse around all day at 1/3-1/2 throttle.  The altitude is set by the throttle with this one.  Just an absolute joy!
