mounts. We like the engine mounts with a gear
hole built in.
Hinge the elevons using packing tape. Put a
layer of 2” tape across the top of the hinge, then
flip over the elevon, and do a layer on the
bottom. Use extra covering material to cover the
hinge if desired. Use epoxy to glue the control
horns into the elevons at this time. (see plans for
diagram)
If you desire the optional air rudder for improved
cross wind handling and aerobatics, cut ONE
SIDE of a flute on Uncle Sam-- at the back of his
neck, extending to the top of the hat. Attach the
rudder to the nose gear servo with a pushrod.
You will need 1 large nylon control horn for this
option. You may also consider adding a 3/16
dowel or carbon rod vertically down through
Uncle Sam for increased stiffness in aerobatic
maneuvers. You can also use string flying wires
to add rigidity.
Add your radio gear to the servo trays. The rear
servo tray has a receiver section to rubber band
to. Run the receiver antenna out the rear of the
plane, and tape down between the elevons. DO
NOT cut the excess wire, let it dangle.
Bolt on your engine to the engine mount before
mounting to set the spacing (if using a 2 piece
mount) Then drill and bolt the engine and mount
to the front of F-1.
Place your fuel tank behind F-1 and run fuel and
vent lines to the engine through F-1
Use threaded end pushrods for your controls.
Connect all surfaces to the servos securely, and
test for free movement. Make sure to use a
sleeve on the outside to eliminate any flexing.
Add your wheels and wheel collars to the main
and nose gear. Make sure that you airplane is
sitting at a slightly nose up attitude on the gear.
This will help the plane rotate for takeoff.
Do a final check over all parts and electronics to
make sure all is correct. And don’t forget to take
a picture now!
Flying
Do the standard range checks, and make sure
your controls are moving in the right directions,
including the nose wheel and throttle. Double
check your CG! Get used to the taxi and show off
your new toy to all those watching! When you
are ready to take off, advance throttle SLOWLY,
you don’t want it to torque around on you. Since
we have no air rudder, if you are in a crosswind,
uses down elevator to keep the nose wheel on
the ground until you are ready to rotate for take
off. When you are up to flying speed, gently ease
off the down, and slowly pull back. It is
responsive, and needs no extra help finding its
home in the clouds! Get used to the way it flies
up high, try a few stalls (it won’t do any thing
crazy) and play around. When it’s time to land,
set up normal, but keep on a little power until
you are over the runway. With its low 1:1 aspect
ratio, it is not the best glider out there. If you find
your self in a power out situation, just keep the
nose down to maintain speed. A little practice up
high will make this kind of incident a snap. You
will find it to be fun to fly and a real crowd
pleaser! Have FUN and be safe!!
