Note on heating the glow plug
The heatsink head on the engine is
treated with an anodized finish which
does not conduct current. Therefore,
when
heating a glow plug, connect
one
lead to the glow plug and the
other
to the
head
or cover
plate
retaining screw.

The MAX-105HZ-R
has been developed expressly for 90
size
helicopter
models,
equipping
the
O.S.
regulator
system.
It's mounting
dimension
is the same
as the
conventional 90 size engines, while the displacement is
increased by 15%. Also, the conventional 90 size models
gear
ratio can
be used
with
this engine
without
any
modification. The regulator system
ensures
an always
steady fuel supply which is required for 3D flights which
require repeated vigorous attitude changes as well as for
F3C flights which require severe mixture control.
With this system, the fuel tank is pressurized by pressure
generated in the crankcase.
The fuel sent by pressure is
regulated
by the regulator installed just ahead
of the
carburetor,
then
sent
into the engine. The
new
silencer
PowerBoost
105 has also been developed to match the
105HZ-R, While the conventional 90 size silencers can also
be used with the 105HZ-R.
A large velocity stack is supplied with the engine to be
installed
on
the
61G
carburetor.
Cool
fresh
air is
conducted to the carburetor intake so that the engine can
develop ideal power characteristics.
When the governor function from Futaba GY-701 or GY-
750
gyro
is employed,
the
Futaba
BPS-1
Back
Plate
Sensor can be installed in a cell on the back plate. By
employing the governor function, more stable flight can
be achieved.
