GREAT PLANES Revolver 50W Instruction Manual page 15

have to make spacers or use a proper length stand-off to
accommodate your engine. For reference, the distance from
the front of the fi rewall to the front of the drive washer is 6-3/4"
[172mm].Read through these instructions to become familiar
with the mounting method.
❏
1. Locate the DLE engine bolt mounting pattern on page 31
of this manual. Tape the pattern onto the front of the fuselage,
aligning the reference marks on the fi rewall with the reference
marks on the pattern.
❏
2. The DLE engine uses 5mm mounting bolts, (not included
with the kit). The drill bit size used here is for the DLE engine.
Double check the hole sizes required for your particular engine.
Drill a pilot hole through each of the marks on the template.
Remove the template and then drill a 13/16" [20mm] clearance
hole through the fi rewall on each of the four pilot holes you
drilled.
❏
3. Mount the engine to the fi rewall with 5mm x 25mm [1"]
bolts and fender washers (not included in the kit or with the
engine). The stand-offs can be permanently mounted to the
fi rewall. Be sure to use thread locker on the bolts. The bolts
that mount the engine to the stand-offs should be snug but
not tightened permanently as you will be removing the engine
several times during the installation procedure.
Many modelers have their own opinions for connectors
and throttle linkage. We have provided materials for a
secure and safe throttle linkage. We have also included a
method to connect a linkage to the choke. This will require
the use of an additional servo for the choke linkage. Some
modelers may prefer a mechanical choke linkage. Review
the following procedure and then modify it as you wish to
fi t your personal preferences.
❏
4. Install 2-56 ball links and 2-56 nuts to both the throttle
and the choke. Be sure to apply a drop of thread locker to the
threads on the ball link.
❏
5. Make marks on the fi rewall where the throttle, choke and
fuel line will pass through. Remove the engine from the stand-
offs. Then, drill a 3/16" [4.8mm] hole through the fi rewall for
the throttle and choke. Drill a 1/4" [6.4mm] hole on the mark
for the fuel line. (Check the diameter of your fuel line to be
sure that a 1/4" [6.4mm] hole is correct).
