Before installing your 2-stroke glow engine, please carefully read the manufacturer's manual and all parts
assembly recommendations including muffler, engine mount, installation, operation and maintenance. The
information contained in this manual is extremely important.
The firewall of the model aircraft is provided in the correct location, with the correct angles for the engine
installation and has markings for 4 engine mount holes.
The larger hole on the firewall is used for fuel lines
and fuel tank ventilation passage and it is not centered, so the engine mount screws holes shall be aligned on
the 4 4mm markings on the firewall.
In the case of a 4-cycle glow engine
it is not necessary
to use the 10mm
plywood part provided with the kit
.
We recommend Great Planes 60 to 120 nylon adjustable mount (GPMG
1091) that includes screws, washers and lock washers to hold the engine to the engine mount. To secure the
engine mount to the firewall drill 4 5mm holes at indicated markings. Use 4 allen 10-
32 x 1 ¼” scre
ws (DUB 582),
4 10-32 blind nuts (DUB 584) and 4 washers on the screws.
