Here's some info. and pics of the Jungmann, so far 3 great flights with no trim required. The plane has excellent flight characteristics, can fly very slow with no bad stall tendencies, mild aerobatics and use of rudder for nice turns, lands like a cub.
Some details: Weight with battery: 80 oz/5 lbs. Power set up: Motor:E-flite power 32, ESC: 60 amp Exceed RC, APC 12x6/E prop. Battery: Hyperion 4S/2500mah/25C Performance: 45 amps @ 650 watts aprox. Radio gear: Spektrum 7ch.,receiver batt. 2S/800mah/15C with castle regulator and separate switch. Servos: Elev/Rud/ Std/Futaba 3004/40 oz. BB, Ailerons/ mini/Corona 939/35 oz. dig./ Metal gear/BB.
Mods: 1. 3.5 in.Dave Brown lite flight wheels, 2. Sullivan spring tail wheel, 3. Upper aileron pushrods with solder clevises at one end and adjustable at other. 4. Large area metals washers bonded to upper wing at cabane attach points. 5. Air exhaust bottom aft fuselage.
Model setup: Perfect as manufactured, Bottom wing/0 deg. Top wing/-1 deg. Stab/+1 deg. Motor 1 deg. down, 2 deg. right. Problems/Fixes: 1. Landing gear covers required aprox. 1/8 in. bevel at top outb. plate to get a little clearance from lower wing surface. 2. Upper wing cabanes required a little tweaking and 2 shim washers for perfect alignment with bottom wing. 3. Fuselage servo tray had a little fwd/aft flex when tail servos where moved, glued 1/4 in spruce stick across fuselage to top of tray and fwd and aft fuselage formers.
Conclusion: Overall the plane is very well built and finished, all parts were straight, no warps noticed. It does requires a level of expertise to properly setup, not a beginners plane, easy for a experienced modeler.
