Install The Fuel Tank & Throttle Servo - GREAT PLANES Reactor Instruction Manual

❏
2. Drill 3/16" [4.8mm] holes at the marks you made. To
reduce tear-out from the back of the holes and to ensure
accuracy, drill smaller pilot holes at the marks first, then
enlarge the holes to 3/16" [4.8mm]. Insert a 6-32 blind nut
into each of the four holes and draw them tight into the
firewall using a 6-32 x 3/4" [19mm] SHCS and #6 flat washer.
❏
3. Loosely attach the nylon engine mount inverted to
the firewall using four 6-32 x 3/4" [19mm] SHCS, four #6 flat
washers and four #6 lock washers.
❏
4. Fit your engine between the engine mount rails, slide
the rails against the engine crankcase, remove the engine
and tighten down the engine mount screws. Place the
engine back onto the mount and position it so that the front
of the drive washer is 4-15/16" [125mm] from the firewall.
❏
5. Use the Great Planes Dead Center
mark the engine mounting holes onto the engine mount.
❏
6. Drill and tap 6-32 holes for the engine mount screws at
the marks you made. Secure the muffler to the engine. In
order to route the muffler along the bottom of the fuselage,
we used an optional O.S. Inside Exhaust Manifold, part
number OSMG2624. Without the manifold, the muffler will
exit the along the side of the fuselage and a portion of the
cowl will need to be cut away for the muffler to pass through.
Attach the engine to the mount using four 6-32 x 3/4" [19mm]
SHCS, four #6 flat washers and four #6 lock washers.
Install the Fuel Tank and Throttle Servo
❏
1. Locate the fuel tank. The hardware needed for the fuel
tank assembly is inside of the tank. Remove the stopper and
shake out the contents.
❏
2. The fuel tank for the Reactor utilizes a three line system.
There is a fill line, carb line, and vent line (to muffler). The
fill line will allow fueling and defueling without unhooking any
fuel lines. The fill line is optional and may be omitted if
desired, or a fuel fill valve may be installed (not included).
❏
3. Slide the three aluminum fuel tubes into the
rubber stopper.
