For the first flight, it is a good idea to have a friend launch

the airplane for you.This allows you to keep your hands on

the radio sticks and correct any trim problems that are

present. Have your friend hold the EP Zero ARF by the

canopy. Throttle up to full power, and have your friend give

the plane a gentle underhanded toss at about a 30° angle

upward. Since the EP Zero ARF has a very high thrust to

weight ratio, the plane will accelerate to flying speed almost

instantly. Climb to a comfortable altitude and throttle back to

a lower power setting. This plane flies great at about half-

throttle when in standard forward flight.

For reassurance and to keep an eye on other traffic, it is a

good idea to have an assistant on the flight line with you.Tell

him to remind you to throttle back once the plane gets to a

comfortable altitude.While full throttle is usually desirable for

takeoff, most models fly more smoothly at reduced speeds.

Take it easy with the EP Zero ARF for the first few flights,

gradually getting acquainted with it as you gain confidence.

Adjust the trims to maintain straight and level flight. After

flying around for a while, and while still at a safe altitude with

plenty of battery power, practice slow flight and execute

practice landing approaches by reducing the throttle to see

how the model handles at slower speeds. Add power to see

how she climbs as well. Continue to fly around, executing

various maneuvers and making mental notes (or having

your assistant write them down) of what trim or C.G.

changes may be required to fine tune the model so it flies

the way you like. Mind your battery power, but use this first

flight to become familiar with your model before landing.

To initiate a landing approach, lower the throttle while on the

downwind leg. Allow the nose of the model to pitch

downward to gradually bleed off altitude. Continue to lose

altitude, but maintain airspeed by keeping the nose down as

you turn onto the crosswind leg.Make your final turn toward

the landing area (into the wind), keeping the nose down to

maintain airspeed and control. Level the attitude when the

model reaches an altitude of about 10 feet, modulating the

throttle as necessary to maintain your glide path and

airspeed. If you are going to overshoot, smoothly advance

the throttle (always ready on the right rudder to counteract

torque) and climb out to make another attempt.When you’re

ready to make your landing and the model is a foot or so off

the deck, cut your throttle and smoothly increase up elevator

until it gently touches down on its belly. Make sure that you

cut your power completely before touchdown, or gearbox

damage may result.

One final note about flying your model: Have a goal or flight

plan in mind for every flight. This can be learning a new

maneuver(s), improving a maneuver(s) you already know, or

learning how the model behaves in certain conditions (such as

on high or low rates). This is not necessarily to improve your

skills

(though it is never a bad idea!)

, but more importantly so

you do not surprise yourself by impulsively attempting a

maneuver and suddenly finding that you’ve run out of time,

altitude or airspeed.Every maneuver should be deliberate, not

impulsive.For example, if you’re going to do a loop, check your

altitude, mind the wind direction (anticipating rudder

corrections that will be required to maintain heading),

remember to throttle back at the top, and make certain you are

on the desired rates (high/low rates). A flight plan greatly

reduces the chances of crashing your model just because of

poor planning and impulsive moves.

Have a ball! But always

stay in control and fly in a safe manner.

GOOD LUCK AND GREAT FLYING!

CAUTION (THIS APPLIES TO ALL

R/C AIRPLANES): If,

while flying, you notice an alarming or unusual sound

such as a low-pitched “buzz,” this may indicate control

surface

flutter

.Flutter occurs when a control surface (such

as an aileron or elevator) or a flying surface (such as a

wing or stab) rapidly vibrates up and down (thus causing

the noise). In extreme cases, if not detected immediately,

flutter can actually cause the control surface to detach or

the flying surface to fail, thus causing loss of control

followed by an impending crash. The best thing to do

when flutter is detected is to slow the model immediately

by reducing power, then land as soon as safely possible.

Identify which surface fluttered (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 fluttered

once, under similar circumstances it will probably flutter

again unless the problem is fixed. Some things which can

cause flutter are; Excessive hinge gap; Not mounting

control horns solidly; Poor fit 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 flutter;Flying an over-

powered model at excessive speeds.
