Glow Engine

The following section only contains information relevant
to installing a glow engine. If you have already installed a
brushless motor then skip this section. The O.S. .65 AX engine
is shown in this section with the stock muffl er. Other model
engines will install in a similar manner. If your throttle arm is
in a different position than what is shown in the photos then
you will need to adjust the location of the throttle pushrod
accordingly.
This section shows the stock muffl er being used and therefore
the angled engine mount pattern was chosen to align the
muffl er in the cavity on the bottom of the fuselage. If you plan
to use a 4-stroke engine or a Pitts style muffl er, then you can
use the engine mount pattern that has the center lines running
horizontally and vertically depending on the engine model. A
.55AX O.S. engine stock muffl er will fi t in the cavity without
the need to cut away the bottom of the cowl. The .65AX stock
muffl er will also fi t in the cavity; however, the majority of the
bottom of the cowl will need to be cut away because the
muffl er will protrude slightly lower than the bottom line of the
fuselage. The .65AX can also be mounted inverted with the
muffl er located on the side of the fuselage (not shown). Choose
the engine orientation that works for you before proceeding.
❏
1. If you are mounting a .55AX or .65AX engine in the
angled orientation, drill a hole for the throttle pushrod in the
fi rewall in the location shown using an 11/64" [4.4 mm] drill bit.
If you are installing a different engine or an inverted engine,
you will need to locate this hole according to the position of
the throttle arm on your carburetor. Be sure you are clearing
the fuel tank area when drilling the hole.
❏
2. Glue the fuel tank support in place. Be sure the notch
for the throttle pushrod tube aligns with the hole you drilled
in the previous step.
❏
3. Cut the included outer pushrod tube to 9" [ 229 mm].
