Shorty is an easy to build and enjoyable to fly trainer for 2-channel radio. Wing construction is easy with prefabricated nose profiles and a wing building jig - a great feature for beginners and less experienced Tips & Notes modellers.

Wings Place cardboard building jig H1 on an even surface and fix with tape or pins. Insert rib jig H2 into building jig H1. Make sure that H2 is fully seated in H1. 7 (balsa) 6 (balsa) 5 (balsa) Insert ribs 1 to 9 into jigs H1 and H2, but do not glue! 4 (balsa) 3 (birch) Rib jig H2 is used for positioning the ribs and is not part of...

Glue wing sheeting panels 10 and 11 together on a flat surface (protect with cling film!). Remove excess glue immediately and secure joint with tape. Weigh down sheeting panels until glue has set. Place wing sheeting on recessed portion of nose profile and match tabs of tip rib 7 with corresponding notches.
Page 5
Insert wing strut brackets 12 into rib 3 and glue in place. Insert brace 13 into rib 1 and glue in place together with root rib 14. Make sure root rib is seated correctly in wing sheeting notches! Note: Root rib 14 is slightly angled due to wing dihedral. Brace 13 takes care of the correct angle.

Glue plywood reinforcements 19 to top of wing centre, flush with trailing edge of wing sheeting. Cut to length reinforcements 20 (30x6-mm trailing edge profile) and fit in place into rib bays beneath plywood reinforcements 19. Glue in place with UHU hart (or similar solvent based wood glue).

Fuselage Glue together fuselage parts 29 to 31 on a flat surface protected with cling film. Secure with tape and weigh down evenly until dry. Glue parts 32 to 38 to fuselage side flush with outer contour. Attention: Make a left and a right fuselage side! For correct positioning of the wing saddle temporarily insert formers 39/40 into...

Glue former/servo tray assembly in place on right fuselage side together with wing retainer 43. Place a suitable weigth onto brace 42 to achieve a good joint with the fuselage side. Glue left fuselage side onto former/servo tray assembly and place fuselage on building board, left side down.

From the rear test-fit motor mount assembly into former 47. Rotate to a horizontal position and align notches with former. Do not glue! Again make sure letter „R“ on motor mount is on the right side, facing up. When parts are a perfect fit, first glue landing gear retainers 48/49 to front of former 39, flush with underside of former.
Page 10
Pull fuselage sides together and gue in place former 53. Continue with formers 54 and 55 and base panel 56. Check fuselage for symmetry! Secure with clamps and tape. Glue part 58 to frame 57 of battery compartment. Remove any excess glue from the opening in frame 57, which will hold a magnet later on.
Page 11
Install snake outers 66 for rudder and elevator control as shown. Snake outers should protrude from frame 40 by 10 mm into servo compartment. Secure snakes with a drop of epoxy to former 40. Glue tail skid 67 and tail skid retainer 68 in place. Fit tail post 69 into former 55 and glue in place.

Cut to size sheeting material 70 (1.5-mm-balsa) and glue to nose section of fuselage. Note grain direction! Secure sheeting material with pins. On a flat surface glue together sheeting parts 71, 72 and secure with tape. Glue sheeting 71, 72 to bottom of nose section (engraved lines facing outside).
Page 13
Tail Unit Assemble stabilizer parts 75 to 80 on a flat surface, then glue together and secure with pins. For best results place trailing edge 75 against a straight edge and pin down. When glue has dried carefully sand stabilizer and round off edges of leading edges and tips.
Page 14
Assemble fin parts 90 to 94 on a flat surface and glue together. Secure with pins. Assemble rudder parts 95 to 100 on a flat surface and glue together. Secure with pins. Carefully sand rudder assembly. Glue control horn 101 to left side of rudder after rudder has been covered.
Page 15
Place tail unit onto fuselage and insert tab at bottom of fin into slot of former 54. Carefully align tail unit with fuselage, then glue in place. Bevel rudder leading edge to right side for adequte control throw. With tape temporarily attach elevator and rudder to stabilizers.
Slide motor cables into fuselage and install motor mount on frame 104 with 4 screws 104. A complete drive set is available for the Shorty. It consists of motor, controller, prop, prop adaptor and 2 servos. aero-naut Order No.: 1366/01 Install rudder and elevator servos (AN-12-MGBBA) in fuselage.
Page 17
Slightly roughen contact surface of wing retaining nuts 107, then from below glue into wing retainer (5-minute-epoxy) and hold in place until glue has cured. Place wing on fuselage and align precisely. Drill reinforcements 19 with 4 mm, locate wing retaining nuts and if necessary adapt bores to retaining nut positions.
Page 18
105.1 Place fuselage with wing installed on a flat surface. Check that wing and tailplane are exactly parallel to each other. Correct, if necessary. Attach wing strut clevices to wing strut connectors, insert wires 105.1 into top ends of wing struts and attach to wing. Correct angle 105.1 of bent sections until wires attach easily to wing strut brackets.
Page 19
Open cover of battery compartment and epoxy magnets 115 into frame and cover. Make sure to check polarity of magnets before you glue! The opional dummy engne is a nice add-on which highlights the scale charcater of the model. Assemble the parts of the dummy engine as shown, add glow plug cables (not included) and attach to fuselage nose.

Workshop just scan the QR-Code and learn how to cover the Shorty‘s tail unit! Apply two coats of thinned down sanding sealer (two parts sanding sealer, one part thinner) to complete model to protect against humidity. Apply sanding sealer also to underside of wing! Leave first coat to dry over night.

Attach rudder and elevator with included hinge tape. First attach hinge tapes 129 to elevator, placing the tape accurately around plywood reinforcemnts 88. Then hold elevator in the downward position and attach to stabilizer. In this way the downward control throw is parctically built-in. Attach rudder to fin with hinge tapes 103, 131.

Optional Tow Release With the optional tow release mechanism you can use the Shorty to tow small gliders to a suitable hight for soaring. The release mechanism can be added now or any time you want. In addition to the parts for the tow release mechanism (included in the kit) you will need another AN-12-MGBBA servo to operate the mechanism.
Page 23
Install tow release servo and attach wire to servo arm. The length of the bent section guarantees, that the wire does not accidentally come free from the servo arm. Adjust travel of servo arm to ensure reliable locked and unlocked positions of mechanism. Cut out reinforcement at trailing edge of wing for release mechanism.
Reduce the power further, touch down and let the model come to a standstill. Once you get used to the characteristics of your Shorty you can attempt to rise off the ground. A well-kempt lawn will usually do it for the Shorty.
