Tango 3.15
Dear Model Making Friend,
Congratulations on your purchase of the Tango. This model
been
developed with state-of-the-art computer
aided design, and
manufactured using
CNC milled and laser cut parts to create a kit that builds into a strong and
accurate structure. Even a less experienced modeler can successfully assemble this great model in
a reasonably
short time.
The assembly mainly uses thin cyano but some parts ie the Wing plug, motor mount etc should be glued with
epoxy resin.
The
Tango
is an extremely good-natured glider with very good flying performance and,
with its large spoiler,
can be
landed very slowly and precisely.
Contents of the kit
The kit includes all parts for the structure of the aircraft.
Other items required are:
• RC system with at least 6 channels (some users recommend a higher channel count so that the two flaps can be
set up individually.
• Complete electric drive: motor, ESC, folding air screw with 40mm spinner.
• Covering (e.g. Oracover)
• Cyano, Epoxy resin, White glue
Recommended drive train:
The motor should not exceed 30 mm diameter, it must have a front mount and should weigh between 1200 and
1700g.
Some possible examples are:
• Hacker A20 EVO with 3S LiPo
• Staufenbiel X-Max X28L outrunner.
• Staufenbiel
DYMOND MASTER HQ 2838 or 2832.
• Poly Tec 400 F5J Motor 2-3S LiPo
Controllers and air screw according to Manufacturer's recommendations.
Recommendation Servos:
4 off KST DS135MG wing, 4 off servo mount frame.
2 off KST DS145MG elevator and rudder.
Recommended control throws (measured at the end of the control surface)
Elevator: +/- 12 mm / Landing mode - 1-3 mm, must be added
Rudder: +/- 30 mm
Aileron: + 15 / - 10 mm
Aileron offsets: Landing +8mm/Speed +2mm/Thermal position -1mm
Flaps/airbrakes: Landing -90° /Speed Position + 2 mm /Thermal position -1.5 mm
Technical data
Wingspan: 3150 mm
Length: 1265mm
Weight: 1550g
Wing loading 24.5 g/dm2
Aerofoil: HQ 30/11-10
Have fun building!

Page 2: Tips And Tricks
Tango 3.15 Tips and tricks A few tips for building the model. Please read carefully. During construction, it is recommended to look back at these tips from time to time. Due to the plug-in system, it is difficult to make mistakes in assembly. - Page 3 Tango 3.15 Attention: The fuselage sides are different lengths. This is to allow for the side thrust. You must assemble the fuselage with the shorter side on the right. The center of gravity is 80mm from the wing leading edge. The holes in the fuselage side serve as a balancing aid.
- Page 4 Tango 3.15 Control hinges may be made using adhesive tape (normal scotch Tape) by applying Inside and outside you get a good hinge. It is also possible to use the covering film to create the hinge. Check the internet for the techniques for doing this.
- Page 5 Tango 3.15 Standard tail It takes only about 15 -20 minutes to assemble the tail surfaces. Dry assemble the wooden parts on your building board and then glue with cyano. As cyano can penetrate through the whole joint you need to ensure that the component does not stick to your building board –...
- Page 6 Tango 3.15 Installation of the tail surfaces onto the carbon tube: First, glue the two plywood strips on fin with a drop of cyano. Note: The pictures show Extensions to the plywood reinforcing piece that extend into the carbon tube. The kit is supplied with the...

Page 7: Fuselage Structure
Tango 3.15 Fuselage structure Glue the formers 2 and 3 and the servo mount at 90 ° with small drops of cyano. Don't put on the base! The kit provides a plywood angle gauge, with the angles needed for construction. - Page 8 Tango 3.15 Carefully clamp the fuselage sides to the internal structure and securely glue. For a firm joint Leave to dry for longer than usual (2-3 min). (Instead of clamps a large rubber band may do.) Glue the 3-piece fuselage bottom together on a flat board.
- Page 9 Tango 3.15 When inserting the 2x5 mm pine strips, it easy to break the formers due to the square ends of the strips. It is therefore a good idea to slightly taper the ends with sandpaper before inserting them. They...
- Page 10 Tango 3.15 Now break out the sanding block and sand down the triangular sections at the nose end to meet the edges of the motor mount. Do not remove any material from the mount Itself. The 6mm balsa pieces can now be glued in place.
- Page 11 Tango 3.15 Add the doublers to the fuselage hatch, the positions are engraved on the hatch inside. The plastic tube is supplied full length and should be cut after assembly. Slide the wire catch into the tube and epoxy the tube in position taking care that the bent portion of the wire protrudes through the slot in the hatch.
- Page 12 Tango 3.15 Mounting the tail boom Glue the two control cable outers into the small circular spacers They should be only lightly glued to avoid problems when installing the control system into the tail boom. Note the positions of the spacers shown on the photo.
- Page 13 Tango 3.15 It is important that the elevator is hinged in place first as it would be impossible to fit it after the rudder is hinged. Note: Refer to the earlier notes on hinging methods. Note: that the photos show the control attached to the control horns using the screw connectors.
- Page 14 Tango 3.15 Wing The photos show the construction of the right wing. The left wing is built up as a mirror image. The Plan is transparent and may be used for both panels by turning it over and using the other side.
- Page 15 Tango 3.15 NOTE: Don't forget to include the Servo mount and the plate for the fuselage locating dowels whilst assembling the ribs Add the two 4x2mm strips at the trailing edge for the support of the triangular flap support strip.
- Page 16 Tango 3.15 The 4x2mm pine strips are a glued in place followed by the triangular aileron spar. contrary to the inner wing, this is fixed with the acute angle downward and the top edge flush with the ribs (see picture).
- Page 17 Tango 3.15 At this point don’t forget to reinforce all the balsa- to- carbon joints with diluted epoxy if you haven’t already done so. Take the glass fiber spar connector for the 12 mm spar and fit the plywood part as per plan. The plywood serves as a centering for the connector.
- Page 18 Tango 3.15 Fit the lower sheeting for the inner wing panel (with the cutout for the multiplex plug) as in the photo. At this point there is also a 3mm balsa Reinforcement to the thin plywood. Reinforce the joint with the leading edge with epoxy and chopped strand fibre filler.
- Page 19 Tango 3.15 Final wing assembly: The drill template is printed on transparent paper. Attach it to the fuselage with masking tape so that the hole positions match the spine nuts in the wing mount. The dashed line and reference to the fuselage side should help.

Page 20: Centre Of Gravity
Tango 3.15 Centre of Gravity Adjust the center of gravity by moving the battery or, if necessary, by adding ballast. The model should balance, as shown in the drawing, in a slightly nose down attitude. The balance cradle and steel wire are included in the kit, with the holes precut in the fuselage sides. - Page 21 A few personal notes from your translator: On reading the reviews on Hyperflight’s site I got the impression that the recommended power setups gave a fairly ‘soft’ climb and so I decided to go with a relatively inexpensive setup initially to assess the performance. It would then not be the end of the word if I decided to upgrade later.
