Engine installation:
NGH 4-stroke engine mounted on a suitable RC aircraft has two common ways of installation, as shown below:

FIG. 3: Rail bracket installation; FIG. 4: Rear bracket installation.
We suggest that RC hobbyist use "FIG. 3" installation. It can effectively reduce the high frequency vibration of
four-stroke engine running at a high speed.

Notice:Please make sure to install a firewall on the back of RC aircraft using metal flat washer or ratchet nut to prevent
the pawl bolt into plywood. Be sure to check before you fly if there are loose bolts.
