Taifun Foxie 0.44 cc Displacement

 Circa 1960 Foxie Prototype







Design History:-
Designed and developed by Hans Hoernlein in 1960 in Germany for the Graupner hobby company. Originally conceived as a glow engine and converted to diesel. The engine was never mass produced and is today very rare.

Design Features:-
The Taifun Foxie is very similar to the early Cox 049 Baby Bee;
In fact Hans Hoernlein manufactured his first Prototype using Cox Babe Bee parts;
Rear Induction via rotary disc valve.

Specifications:-
Bore 8.0 mm
Stroke 9.0 mm
Rpm 18,000 rpm
Power 0.04 Hp
Total combustion 0.44 cc
Weight 35 gram


Observations:-
It was designed by Hans Hoernlein, the man behind the fantastic Taifun engines. The orginal engine was conceived as a glow engine. The Graupner Hobby Company thought at the time, that the future was in the glow engines. The Taifun diesel era came slowly after many successful years, to a end. Only the Bison and Sprint along with the Foxie were the only Taifun glow engines. A lot of the Foxie parts were  already produced include the boxes when the decision to suspend production came. Only 5 engines were given for a test, to modelers who were close employees or friends to the Graupner company.
I don't know whether the engine did not perform well, or if the costs were too high was the factor which caused the decision of Johanes Graupner, not to produce the engine. But, because of this decision Hans Hoernlein left the company and started producing engines under his own label..the "Profi" engine line.
My little  engine is built as a diesel version by Ronald Valentine, the master of miniature model engines. Because of the reardisc induction, its possible to run it at high RPM. The engine shown here is not yet run-in and the propeller was also on the big side, that's why it is not running at full speed....but a lovely little diesel....that's for sure! Happy to have him in my collection.
Thanks for watching!
