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.
