INSTALLATION OF THE ENGINE
Rigid hardwood
(e.g. maple)
At least 15mm(1/2")
At least
15mm(1/2")
A typical method of beam
mounting is shown below, left.
Installation in the model
Front view Side view
Top surfaces are not in the
same plane. Opposite beam
Top surfaces are not in the
same plane.
Re-align the surfaces as necessary Engine does not rest firmly.
CORRECT
INCORRECT
Top surfaces are in the same plane.
Use mounting screws of a diameter (between 5mm appropriate to engine size.
Hardwood mounting beams
Radial motor mount
(cast aluminum)
How to fasten the mounting screws.
Before connecting the throttle-lever / servo linkage, make
sure that no part of the linkage interferes with the internal
structure of the aircraft or wiring, etc., when the throttle is
fully open or fully closed.
Set the throttle lever linkage so that the throttle rotor is (a)
fully open when the transmitter throttle stick is fully
advanced and (b) fully closed when the throttle stick is fully
retarded. Adjustment of the throttle rotor opening at the
idling position can then be made with the throttle trim lever
on the transmitter. (Select throttle-lever and servo-horn
hole positions that will avoid excessive pushrod travel
causing the throttle to bind at either end.)
THROTTLE LINKAGE
When adjusting the throttle lever angle, relative to the
rotor,hold the rotor at about half-way between the open
and closed positions while loosening and tightening the
fixing screw, otherwise the rotor, rotor guide
screw,throttle stop screw or carburettor body may
become burred and damaged.
Note:
•
•
Tighten second nut firmly
down onto first nut.
Tighten this nut first.
Steel washer
5mm steel screw
Spring washer
or lock washer
Hardwood such as
cherry or maple.
Spring washer
5mm steel Allen
screw
5mm steel nut
Make sure that the mounting beams are parallel and that their
top surfaces are in the same plane.
NOTE: Be sure to secure large enough air intake and
outlet area for cooling the engine in order not to overheat
the engine.
