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, 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; Excessive free play in servo gears;

Insecure servo mounting.

Preparations

First of all, if you are flying with other flyers, check to

make sure they are not flying or testing on the same

frequency as your model. Try to find an experienced

pilot to help you with your first flights. Although the Fling

ARF is very easy to fly, an experienced pilot can save you a

lot of time and possible aggravation by helping you get your

model in the air smoothly.

Find a BIG, OPEN field for your first flights – the bigger the

better as you won't have to worry about where you need to

land. Ground based objects (trees, poles, buildings, etc.)

seem to attract model airplanes like a magnet.

Trim Flights

It is a good idea to do a couple of trim flights before each

flying session to make sure the plane is still in trim and the

radio is working properly. The model will survive a hard

FLYING

landing from 6 feet [2M] much better than it will one from

several hundred feet. The first few trim flights should be

done over a grass field. The longer the grass, the better

(more cushion). Turn on the transmitter first and then the

receiver. Hold the Fling ARF under the wing with the nose

pointed slightly down and directly into the wind as shown in

the photo. It is very important that you launch the model with

the wings level and the nose pointing at a spot on the

ground about 50 feet in front of you. Have a friend stand off

to the side of you and tell you whether the nose is pointing

up or down. Show your friend the preceding picture so he

will know what to look for. If the sailplane is launched with

the nose up or launched too hard it will climb a few feet, stall

and fall nose-first straight down. With the nose pointed down

slightly, the sailplane will accelerate down until it picks up

enough flying speed and then level off and glide forward.

The plane should be launched with a gentle push forward.

With a little practice you will be able to launch it at just the

right speed so it soars straight ahead in a long and

impressive glide path. Adjust the trims on your transmitter to

get the plane to fly straight ahead in a smooth glide path.

Once you get the hang of launching, you can try turning the

plane during the trim flights by gently applying a "touch" of

right or left rudder. You can also try "flaring" the landings by

slowly applying a touch of up elevator (pull the stick back) as

the plane nears the ground. The Fling ARF will continue to

fly just a few inches off the ground for a surprisingly long

distance. It is important you don't "over-control" the model.

Make any control inputs slowly and smoothly rather than

moving the transmitter sticks abruptly.

First Flights

Note: Remember that your radio control responds as if

you were sitting in the cockpit. When you push the

transmitter stick to the right, the rudder moves to the

plane's right! This means that when the plane is flying

towards you it may seem like the rudder controls are

reversed (when you give "right" rudder the plane turns

to your left–which is the plane's "right"). It is sometimes

easier to learn to fly the plane if you always face your body

in the direction the plane is flying and look over your

shoulder to watch the model.

Don't worry about accomplishing very much on your first

flights. Use these flights to get the "feel" of the controls and

the Fling's flying characteristics. Try to keep the plane

upwind and just perform some gentle "S-turns" (always

turning into the wind) until it is time to set up for landing.

Have a helper adjust the trims on your transmitter (a little at

a time) until the plane will fly straight and level with the

transmitter sticks in their neutral positions. It can be very

hard for a beginner to fly a plane straight towards him as he

would have to do if the plane were downwind and every

mistake took the plane a little farther downwind. When it is

time to land, just continue performing the gentle "S-turns"

upwind and let the plane glide onto the ground. Don't worry

about where the plane lands–just miss any trees, etc.
