Push Rod Installation:
Glue all of the control horns in place with CA. All
pushrods are made as shown. Use the .032 wire to make
the Z ends. Install the Z ends to the control horns and
servo arms. Test fit each carbon rod and trim as needed.
Add a small drop of CA to the wire/carbon joint. The
1/16” heat shrink is used to secure the 1mm carbon
pushrod to the .032 wire.
Make sure the control
surface and the servo are centered before heating
the shrink sleeve.
Any adjustments past this point must
be made with the sub-trim function of your computer
radio.
Note: The aileron pushrods are made from the
thicker 1.5 mm carbon rod to reduce flexing.
When installing the long elevator and rudder pushrods,
make sure to install the included plywood pushrod guides
as needed along the fuselage sides. Slip 3 of these
standoffs onto the elevator and rudder pushrods before
attaching the z ends. Cut small slots in the fuse and glue
the pushrod guides in place as needed to eliminate any
pushrod flex.
Flight set-up:
Use double stick Velcro on the battery and airframe to
secure the battery to the bottom of the horizontal
fuselage in a location that gives the model proper
balance.
A good starting balance point is about one inch in front of
the canopy. Adjust the battery location back and forth to
suit your flying style. Use your computer radio to set the
final sub-trims, exponential and dual rates. Double check
the control directions before your first flight.
With
proper CG, the plane should fly nearly the same
upright or upside-down.
Good pilots experiment with
various battery locations until the CG feels just right.
For indoor flying, we use 2 cell lipo packs rated at 20C.
Batteries of 300 to 480 mah are perfect for giving good
flight times and plenty of power. The final airplane weight
should be between 5.0 and 5.5 oz.
We hope you like the MX2. It was designed by Champion
pilot RJ Gritter to meet the needs of the indoor contest
pilot and the backyard sport pilot.
Thank You,
