As shown in the photo, connect/glue the tank and the throttle servo into the fuselage
using the brackets. Depending on the motor used, the servo is installed to right or left
of the tank.
Installing the motor
This section describes the installation of the OS MAX GT 33, but the procedure is the
same for other engines.
Four holes for the rubber damping elements have to be drilled into the firewall to
match the particular engine.
The centre of the motor is marked on the firewall. Drill Ø 6 mm holes to match the
attachment holes for the engine.
From the included aluminium pipe, cut off four pieces of 30 mm each. In each
section, to the right and left, put on an aluminium bushing and screw the motor to the
bulkhead as shown in the photo. Cut the protruding ends of the four bolts off flush
with the nuts.
The throttle rod is adjusted so that the carburettor is half open when the servo is in
centre position. The servo travel must be adjusted so that the engine stops when the
throttle stick and trim are at the full back position.
