- Page 2 I have designed a model that allows long flight times, with the ability to scan a large area for thermals. At the same time the X-RES, is a model which the less experienced pilots can learn quickly. I wish a lot of joy with the model...
- Page 3 X-RES 2. Building Instructions General construction We tried to keep the structure of the aircraft as easy as possible, without compromising on the performance. However, it is very important to proceed with the necessary care to build a straight and high-performance model.
- Page 4 X-RES Additional Resources / Tools To build the following tools are required: • Xacto knife • Aluminum ruler • Set Square • Small handsaw • Sanding blocks (80, 120, 180) • Swiss Files • Pins • needle-nose pliers • Cannula for superglue 0.9 mm are available from the pharmacy •...
- Page 5 X-RES 2.2 Fuselage construction 2.2.1 Material for the fuselage 1. 3 mm plywood bulkheads for fuselage 1. 0.8 mm plywood reinforcements for sides and bottom of fuselage 1. 2 mm balsa fuselage, bottom and sides 1. 2 mm balsa side and bottom + small parts for the hatch cover 2.
- Page 6 X-RES Glue the fuse bulkheads with superglue. Make sure that these are perpendicular to the fuse sides. Now two 4x4mm balsa longerons are glued in place on each fuselage side. Up to the wing saddle (bulkhead 5) on top and to the nose on the bottom.
- Page 7 X-RES Taper the longerons at the rudder cutout so the back end of the fuse can be glued to the rudder. Now the pushrod housings are sanded with rough sandpaper and run through the bulkheads, but not glued. 7 Of 37...
- Page 8 X-RES Next, the fuselage sides are glued together. Make sure they are parallel. Before the frame is bonded at the end of the plywood reinforcement, insert the wing retainer. Insert the 4 mm sheet of plywood with the 5 mm threaded hole toward the front of the fuselage.
- Page 9 X-RES Fuselage top with pushrod housing shown. Glued fuselage bottom. Finally, the adjustable tow hook and the balsa nose are glued with white glue. To accommodate trim weight, the nose can be slightly hollowed. 9 Of 37...
- Page 10 X-RES Wing retention system (I built the wing first because of this step). If the wing locating dowel is not installed, drill a 5mm (0.196 diameter or # 9 drill) hole in the leading edge and install the locating dowel at the center of the wing.

X-RES Fuselage Sanding The fuselage edges can be slightly rounded. The nose is first sanded to match the fuselage walls and rounded thereafter. To the rear, the balsa of the sides can be sanded down. Sand the rear end of the fuselage to match rudder thickness. - Page 12 X-RES 12 Of 37...
- Page 13 X-RES The elevator pivot is located in front of the last bulkhead. Notch the fuse sides for the elevator mounting side plates. Install the horizontal elevator plate onto the side plates using a piece of wire. Glue the elevator mounting plates to the fuse sides, making sure the horizontal elevator plate is parallel and level with the wing.
- Page 14 X-RES 2.4 Construction Stage - Wing The material for the sheeting of the wing should be cut in each phase of construction. Some small pieces, however, are not shown here. Therefore, do not throw away the cut off pieces. 2.4.2 Building Phase – Center Wing Section 2.4.2.1 Material Center Wing...
- Page 15 X-RES Aligning the wing plan. Cutting and gluing the 6x2 spar to the bottom sheeting. The ribs are cut and sanded to fit on the spruce spar. The 3mm balsa spar webbing is also prepared. The two ribs adjacent to the root rib have a section for the webs.
- Page 16 X-RES The two root ribs A1 from 5 mm Balsa and 1.5 mm plywood ribs A2 should be glued to each other. Use epoxy. Glue in the 1.5mm plywood reinforcement at the wing mounting bolt position. Place ribs on the plan and glue to spar. Do not glue ribs to bottom sheeting yet. Ribs A9 are glued at a 5 degree angle, using the 5 deg jig.
- Page 17 X-RES Aligning end rib A9 with 5 ° angle jig. Roughen and thoroughly clean aluminum wing joiner tubes. Slide aluminum tube into ribs A-9 and A- 8. Align at 90° to end rib. Gap between tube and spar webbing should be filled in with scrap 1.5mm plywood.
- Page 18 X-RES Glue in the top spar using plenty of glue. Carefully remove assembly from building board and turn over. Fit and glue on the trailing edge balsa, flush with the top of the ribs, gluing from the bottom side. The wing can be turned right side up and the trailing edge can be sanded to a taper on the top side, starting from about 12 mm from the edge, so it is about 1mm thick at the trailing edge.
- Page 19 X-RES Thereafter, the middle part can be taken from the Plan and the bottom sheeting can be fully glued to the ribs. 19 Of 37...
- Page 20 X-RES Now a strip of 2 mm balsa is cut from scrap balsa sheet and glued to the front of the ribs. Take a long sanding block to make the front edge straight. After drying, cover the ribs to protect them and sand the 2mm strip to shape for sheeting.
- Page 21 X-RES Mid span wing with spruce spar and glued AL wing joiner tubes. Plug end of tube with wood. Now the upper sheeting can be glued to the ribs. 21 Of 37...
- Page 22 X-RES Then turn around and glue the ribs from behind to spar. Now, through the gap between the strip on the nose and the upper sheeting, glue the upper sheeting to the ribs. Here it is advisable to use thin needles and take advantage of the fluidity of the superglue.
- Page 23 X-RES The nose can now be sanded flat from the beginning to the 2 mm strip and a 4x10mm balsa strip leading edge is glued on. Now the middle 1.5mm sheeting is glued on. Sand the leading edge to shape using the ply jigs to get the correct shape.
- Page 24 X-RES Fitting and Actuation of the Spoiler 2.4.7 Now the spoilers can be installed. Frame around the edges per the plan, with 3mm scrap, 3x3mm strip, and the 1.5x10 strip from scrap. The spoilers are from the included 3mm balsa. Cut and fit into the recess and sand from the top side for a flush fit.

- Page 26 X-RES Fit the aluminum wing joiner tubes and check alignment for each mid span wing to the center wing. The exact angle is not critical, they just need to be the same for each side. When adjusted, glue in place with epoxy. Shim the gap between the tube and the spar webs with scrap ply.
- Page 27 Glue the bottom spruce spar to the trailing edge of the bottom sheeting. Bottom sheeting extends out past the wingtip. These photos are not from the X-RES and differ in details. Fit the spar shear webs and ribs. Angle rib C1 for dihedral using the 6 degree ply template. Washout 3-4 mm can be built into the wing tip, or it can be done with the covering later.
- Page 28 X-RES Make a false leading edge from 2mm scrap balsa. Shape top edge for upper sheeting. Cut top sheeting so it will extend over the wing tip. Glue on upper sheeting. 28 Of 37...
- Page 29 X-RES Sand front edge of outer wing flat and glue on 4x10 mm leading edge. Sand leading edge to shape using the plywood templates. They are marked with the rib locations they correspond to. Wing tips Sand the wingtip to shape following the rib shape of the outermost rib. Round the tip to shape per plans.
- Page 30 X-RES Joining Mid Span and Center wing Sand the joint between the center wing and the mid span wing so there is a good fit between them. Glue in the CF anti rotation pegs. 30 Of 37...

- Page 32 X-RES Sanding of the tail Sand the tail surface according to the plan detail. Sand the control surface part of the rudder down to approx 1.2mm at the trailing edge. Sand the leading edge down to 3mm. On the leading edge of the rudder and trailing edge of the vertical stabilizer sand the edges round, making both sides symmetrical.
- Page 33 X-RES Covering Now the plane can be covered. This is not described completely here, however, some tips: Temperature of the iron should only activate the adhesive 130-150 degrees C. Tack covering to undersides first, then the topside. Overlap top covering onto bottom covering. Increase iron temperature to shrink covering.

Set the height adjustment for airbrakes at a higher altitude. Ballast Camber Anyone who wants to use the X-RES for pure leisure fly does not need ballast chamber. but in competition it is quite reasonable, that the model weight be adapted to the weather conditions. - Page 35 I wish you much joy in flying, thermalling and successful participation in RES competitions! Let Your X-RES always be insight! All the best and have fun!
