Tools:
- sandpaper №150-80; № 320-240
- epoxy with microcellulose;
Fuselage assembly of Maxa Pro EL
- adhesive tape;
- paper tape (used for protection against an
excess of epoxy resin)
- superglue, CA (medium viscosity and low
viscosity);
1) For install the servo platform in the fuselage sanded the place inserts in the fuselage and the side surface of
the platform by sandpaper № 150-80
2) Try how the servo platform is fitted, by slipping
it through the canopy hole (platform front side is wider).
Center of wing electrical connectors must coincide with
the center of the servo platform. Connectors will be
located between the servos. (approximate size is on
figure). The platform should be placed horizontally
along the axis of the tail boom. (front part of the
platform is above the rear one).
3) Glue platform by superglue carefully. Please fix
it by the liquid superglue in two points first, then
recheck and spill platform by medium superglue.
Рiс.1 – Proper installation servo platform in
fuselage
Рiс.2 – Preparing the fuselage to install servo platform
4) Prepare the servo-horns with 12mm arm
5) Screw the bearing nut to the back side of the servo horn by screw M2. Screws head almost will hide in the
servo horn hole.

6) Put the tail boom with rods (please fix the tail on
the tail boom in neutral position) and mark the rods length
according to centers of the servos horn bearing spots on
board. Front servo is rudder one with rod right side (by
flight), rear servo is elevator one with the rod in left side.
7) Remove the boom from the fuselage and measure
the distance from your marks required to clevis andthread
rod tip installation (clevis must be adjusted to ± 3 mm at
the rod tip). Cut the carbon rod according to your measure.
Cut the rod tube to the edge of the 10mm longer rod tip.
Sand the gluing spot in the rod by № 320-240 sandpaper
and glue the rod tip by superglue. Note: keep the tail boom
vertically with the fir in top, so the flown superglue will
not fix the pipe to the rod.
Рiс.3 – Bonding of pushrod and horns rods of tail
8) Install the horns with the bearings on the rod clevises.
9) Refit the tail boom and install servo horn bearings into the appropriate slots. Adjust the length of the rods
by thread, that the horns (in neutral rudders) were perpendicular to the axis of the fuselage. Check how the control
system working.
10) Notice how the distance from the rod to the surface of the fuselage.
11) Disassemble the fuselage and glue on the edges of
the tubes rods pieces of balsa plywood or other material for
fixation rod tubes to the fuselage. The width of these bands
make according to claim 10. Be careful that the superglue
will not filled the rods for this keep the tail boom rudder
side to the bottom.
12) Assemble the fuselage again for a final check.
13) Disassemble the fuselage, spread resin with
microcellulose to the tail boom inside (by gloved finger,
thin, rubbing the tail boom) and outside the fuselage. Also
smear resin to the strips on the rods for fixed it to the
fuselage.
14) Assemble the fuselage. Set servos horn bearing into the slots. Check the operation of the control system
and fixation rod pipes to the fuselage.
15) Screw the central panel and check the stabilizer/ central panel position.
16) The tail boom must be in the central of the gap rate. In this case will be right stabilizer angle.
17) Wipe off any excess resin and secure the beam by glued tape prior to polymerization of the resin.
Рiс.4 - balsa plywood for fixation rod tubes to the fuselage
