Specifications

The Bücker Jungmeister was developed in 1935 by Carl Bücker and Swedish designer Anders Anderson.This aircraft was a great success and due to its exellent performance, it served as a aerobatic trainer in many country.

The "BEVO" :
This Buecker-Jungmeister was manufactured in Germany in 1936
and brought to the U.S.A. on the dirigible Hindenburg, by the late Capt. Alex Papana  (famed Rumanian Aerobatic pilot) ,
who exhibited it in the1936 National Air Races at Los Angeles  and  other National and International meets.  
Col. Mike Murphy ,  International Aerobatic Champion
for several years,   purchased the plane in 1940 and flew it in all major
U.S.A. meets and competitions until retiring.
Beverly Howard purchased this plane from Col. Murphy in 1946 and
has flown it in all major meets since that time ,  including meets in
France and Germany in 1950. This type plane was designed as a sport
plane  but  was  used to  train  many  pilots of the German Luftwaffe
prior to Worldwar II. Wing span is 21ft. 7in. Empty weight is 925lbs and is powered by a 7 cylinder radial  185 h.p.  Warner (american)  engine.

Load Factor
For aerobatics, the maximum  load factor for the Jungmann is +6g,  -3,5g.
Stalls
Stall characteristics are smooth. 
Aileron use is not recommended to maintain lateral control. Only rudder is effective for this control.
Recover from a stall :
1. Lower the nose and add full power simultaneously.
2. Use the rudder to maintain lateral control.
Spins
Normal or inverted spins  approved.
Spin Recovery
1. Throttle — Closed
2. Ailerons — Neutral
3. Rudder —Full deflection in the opposite direction to rotation
Manoeuvring Speed, V A
Above manoeuvring speed, control deflections must be reduced.
Never Exceed Speed, V NE
The V NE, is the maximum safe structural airspeed.

Snap roll
In level flight at 85 mph very rapidly apply back stick and simultaneously apply full rudder in the desired direction of roll,  Aileron may or may not be used depending on the characteristics of your airplane.Some won’t snap well without aileron and some don’t seem to need it, the Bückers for instance.
the Bückers Jungmann and Jungmeister are the most lovely snapping of airplanes. The break is easy to achieve .
The snap is smooth and recovery can be left until just before level.

Inverted spin
As the stall speed 
Push the nose up as you reduce the throttle closed.
stick full forward and booted full  rudder. 
in FS9 and only : At stall speed, stick forward and left,
full right rudder  until the spin start !

Spin
holding full back stick and full rudder, until the spin start !
NO inadvertent aileron
Any aileron input will alter the spin characteristics. 
Neutral ailerons are essential for a smooth spin.
Recovery:
Start the stick forward from the aft stop,
maintaining full in-spin rudder.
before the recovery point, aggressively apply full opposite rudder.

The loop
 
Most good loops result in about 3.5 G but can be done at less. More than 4.0 is not usually required.

Entry speed 110 knots
a smooth but firm back pressure on the stick
Check each wingtip to show vertical
momentarily decrease back pressure to float over the top,
and check again the wingtip for level
As you pitch through vertical check wingtip and
maintain back pressure as airspeed increases
Pull for 3.5 g as you exit the loop.

Aileron roll Recreation style
Entry speed  100/110 knots

Raise the nose smoothly but aggressively  to about 30 degrees above the horizon prior to starting the roll.
Before introducing any aileron the stick is "checked" forward check the stick to neutral and only then apply aileron toward the desired direction of roll, accompanied by a little rudder to coordinate.

Aileron roll Competition style
Entry speed  100/110 knots

Raise the nosea little above the horizon prior to starting the roll.
Before introducing any aileron the stick is "checked" forward check the stick to neutral and only then apply full aileron toward the desired direction of roll, accompanied by a full rudder
