Great Planes Patriot XL Kit - GPMA0450 - Manual (Page 32)

❏
2. Remove the tank and fuelproof the fuel tank
compartment with thinned out epoxy or fuelproof doping.
❏
3. Drill two 1/4" [6mm] holes in the firewall above the tank
floor as shown. Route the two 12" [300mm] lengths of fuel
tubing from the tank through these holes and into the tank
compartment. Pull the fuel tank into place with the fuel tubing.
Note: Some modelers may wish to wrap the tank in foam
prior to installing it. This is fine, but it will be a tight fit. Simply
bracing it with small balsa blocks after sliding it in will be
perfectly acceptable.
❏
1. Cut the “spreader bars” from the included Great Planes
engine mount, and then use a hobby knife to remove any
flashing leftover from the molding process so that the halves
fit together well.
❏
2. Temporarily attach the engine mount to the firewall with
four 6-32 x 1" socket head bolts and #6 flat washers but do
not tighten the screws all the way.
❏
3. Place the engine on the mount and slide the halves in
or out until the engine fits. When the engine mount is
adjusted and positioned, tighten the mounting screws.
❏
4. Position the engine on the mount so the drive washer (or
the back of the spinner) is 5-3/8" [137mm] from the firewall.
❏
5. Use the Great Planes Dead Center ™ Engine Mount
Hole Locator or another method to mark the locations of the
bolt holes. Remove the engine from the mount and drill four
#36 or 7/64" [2.8mm] holes. Tap the holes with a 6-32 tap.
❏
6. Bolt the engine to the mount with four 6-32 x 3/4"
[19mm] socket head screws, #6 washers, and lock washers.
❏
7. If installing retracts, proceed to “ Install the Servos
and Pushrods.”
❏
8. Mount the nose gear to the engine mount as shown
using a nylon steering arm with a 5/32" wheel collar and a
6-32 x 1/2" [13mm] socket head cap screw, another 5-32"
wheel collar and a 6-32 set screw. Position the wheel collars
so the gear will be positioned as shown (with the coil in the
wire approximately 1/8" [3mm] from the bottom of the
fuselage.) Be sure to grind flat spots on the nose gear wire
where the steering arm set screw and wheel collar set
screw will tighten.
