Before installing rudder controls wait until the airplane is completed and check the balance.
You can use pull-pull if little or no tail weight is needed, otherwise there are two servo
mounts in the tail for rudder servos if the plane is nose heavy.
You might want to re-glue the hatch hold downs to the hatch, they have been known to
come loose. The hatch can benefit from a second set of hold downs also.
I strongly recommend dual aileron servos for safety. In testing, one aileron linkage failed
when the arm fell off the servo and the ensuing flutter caused pushrod on the opposite aileron
to fail. However dual servos are not required, the plane flies beautifully with a single Hitec
5645 digital servo in each wing.
Use a backup engine kill device besides the throttle. I use a servo to actuate the choke which
can also be used to kill the engine, but a kill switch is a good solution also.
Balance the plane carefully. The Giles wing does not like to be tail heavy.If you fly it tail
heavy it can be beyond the capabilities of the best pilot. Balance initially at 1” in front of
the centre of the wing tube and work back a little at a time. In testing we have found that
with a 5 pound engine the plane will come very close to balancing with pull-pull. With a
lighter engine the plane, even with pull-pull, will likely be tail heavy. In that case consider
using a heavier spinner and/or ignition batteries. The plane can be made to balance without
ballast if you do some planning as you install things.
1. Open and inspect everything. There should be a fuselage with hatch, wing tube and stab
tubes. Also 2 stabs w/elevators, rudder, landing gear and hardware (nuts and bolts)
package, cowl, canopy, wheel pants. Hinges are either in the control surfaces or supplied
separately, but they are not glued in yet.
2. Mount the engine. Distance from firewall to cowl face is 6.5” (more or less The cowl
mounts are already set, use the cowl ring to align the engine. Right thrust is already built
into the firewall.
3. Glue the hinges with whatever you like to use, but epoxy is probably best
4. Hatch mounts are obvious, drill 1/8” hole and use a 4-40 blind nut inside. Mount the
canopy us ing t h e m e th od y ou p r ef e r ; s c r e ws , t ap e , g lu e . W h a te v e r works for you.
5. The horizontal stab assembly mounts on one 1/2” aluminum tube. Two 4mm screws
are used at each side to retain the stab assemblies Use loctite on these screws, and use
washers and lock washers on them as well. Blue loctite is appropriate.
6. The control surfaces have pre-drilled hard points to accept rocket city type horns. There
are three hard points on the ailerons. Use the center hard point if using a single servo, the
inner and outer hard points are for dual aileron servos. The rudder has two hard points,
the upper one is for the tiller and the lower one is used to steer the tail wheel. Do not drill
the lower one out, a 6-32 tiller is sufficient in that position.
7. Servo installation should be obvious. Elevator servos trays are located in the tail below
