TAKEOFF
Before you get ready to takeoff, see how the model
handles on the ground by doing a few practice runs at
low speeds
on the runway. Hold “up” elevator to keep
the tail wheel on the ground. If necessary, adjust the tail
wheel so the model will roll straight down the runway. If
you need to calm your nerves before the maiden fl ight,
shut the engine down and bring the model back into
the pits. Top off the fuel, then check all fasteners and
control linkages for peace of mind.
The Zero has a wide landing gear stance making ground
handling very good and relatively easy for maintaining
straight take-offs. Taking off directly into the wind makes
ground handling relatively easy. We would recommend
that whenever possible you take off and land directly
into the wind. Taking off in a cross wind or landing cross
wind you will need to be quick on the rudder and may
need to use ailerons to help keep the wing level during
the take off or landing roll out.
When you’re ready, point the model straight down the
runway, directly into the wind, and hold a bit of up elevator
to keep the tail on the ground to maintain tail wheel
steering, then gradually advance the throttle. As the
model gains speed decrease up elevator allowing the
tail to come off the ground. One of the most important
things to remember with a tail dragger is to always
be ready to apply
right
rudder to counteract engine
torque. Gain as much speed as your runway and fl ying
FLYING
IMPORTANT!!!
The Zero does not possess the
self-recovery characteristics of a primary R/C trainer
and should be fl own only by experienced R/C pilots.
FUEL MIXTURE ADJUSTMENTS
A fully cowled engine may run at a higher temperature
than an un-cowled engine. For this reason, the fuel
mixture should be richened so the engine runs at about
200 rpm below peak speed. By running the engine
slightly rich, you will help prevent dead-stick landings
caused by overheating.
CAUTION
(THIS APPLIES TO ALL R/C AIRPLANES):
If, while fl ying, you notice an alarming or unusual
sound such as a low-pitched “buzz,” this may indicate
control surface
fl utter.
Flutter occurs when a control
surface (such as an aileron or elevator) or a fl ying
surface (such as a wing or stab) rapidly vibrates up
and down (thus causing the noise). In extreme cases,
if not detected immediately, fl utter can actually cause
the control surface to detach or the fl ying surface
to fail, thus causing loss of control followed by an
impending crash. The best thing to do when fl utter
is detected is to slow the model
immediately
by
reducing power, then land as soon as safely possible.
Identify which surface fl uttered (so the problem may
be resolved) by checking all the servo grommets
for deterioration or signs of vibration. Make certain
all pushrod linkages are secure and free of play. If
it fl uttered once, under similar circumstances it will
probably fl utter again unless the problem is fi xed.
Some things which can cause fl utter are; Excessive
hinge gap; Not mounting control horns solidly; Poor
fi t of clevis pin in horn; Side-play of wire pushrods
caused by large bends; Excessive free play in servo
gears; Insecure servo mounting; and one of the most
prevalent causes of fl utter; Flying an over-powered
model at excessive speeds.
❏
6. Use threadlocking compound to secure critical
fasteners such as the set screws that hold the wheel
axles to the struts, screws that hold the carburetor arm
(if applicable), screw-lock pushrod connectors, etc.
❏
7. Add a drop of oil to the axles so the wheels will
turn freely.
❏
8. Make sure all hinges are
securely
glued in place.
❏
9. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, cowl mounting
screws, etc.).
❏
10. Confi rm that all controls operate in the correct
direction and the throws are set up according to the
manual.
❏
11. Make sure there are silicone retainers on all the
clevises and that all servo arms are secured to the
servos with the screws included with your radio.
❏
12. Secure connections between servo wires and
Y-connectors or servo extensions, and the connection
between your battery pack and the on/off switch with
vinyl tape, heat shrink tubing or special clips suitable
for that purpose.
❏
13. Make sure any servo extension cords you may
have used do not interfere with other systems (servo
arms, pushrods, etc.).
❏
14. Secure the pressure tap (if used) to the muffl er
with high temp RTV silicone, thread locking compound
or J.B. Weld.
❏
15. Make sure the fuel lines are connected and are
not kinked.
❏
16. Balance your propeller (and spare propellers).
❏
17. Tighten the propeller nut and spinner.
❏
18. Place your name, address, AMA number and
telephone number on or inside your model.
❏
19. Cycle your receiver battery pack (if necessary)
and make sure it is fully charged.
❏
20. If you wish to photograph your model, do so
before your fi rst fl ight.
❏
21. Range check your radio when you get to the
fl ying fi eld.
