The Jungmann has the best control harmony, very sensitive,
delightfully aerobatic. I've flown the APM
Jungmann with the Lycoming 0-320 (HB UUA), the 125 Tigre engine
(G CDRU), and the 150 Tigre
engine (D ENNN). The best balanced was the Hirth engined
aeroplane the others being nose heavy.
All Jungmanns are gorgeous to fly.

Jungmann outside the Condor Club hangar. Unlike a lot of biplanes this aeroplane was snug in the winter with few drafts to make you feel uncomfortable. |

The Hirth HM 504 A10 engine I found in Stuttgart and fitted at Stapleford Tawney. This 105 HP engine was self contained with its oil tank in the crankcase lid. A double float in the carb allowed inverted flight, and roller bearings on the little and big ends that allowed a 50% overspeed of the engine, normal max RPM = 2530. The exhaust exited forward to avoid any petrol that might leak especially since you got a massive flame at zero G, (like in knife edge flight).. |

The Jungmann was well engineered for maintenance tasks. |
