Set up the Firebat ARF so it has the following control

surface throws:

CANARD (ELEVATOR):

(High Rate)

9/16" [15mm] up and down

(Low Rate)

3/8" [10mm] up and down

AILERONS:

(High Rate)

3/8" [10mm] up and down

(Low Rate)

5/16" [8mm] up and down

Second to the C.G., the control throws have the greatest

effect on the way a model flies. Set the throws as close to

these settings as possible. If you have too much control

throw the model may respond too quickly. If you do not

have enough throw you may not be able to maneuver the

model or have enough control to land it when the motor

is off.

Balance the Model (C.G.)

IMPORTANT: The C.G. (center of gravity), or balance

point has the greatest effect on how a model flies. Do not

overlook this important procedure. Modelers who do so

often find that the airplane is difficult to control, or out of

control after it is too late. Preserve your model and insure

that the first flight won't be the last by balancing the model

according to the following instructions.

The C.G. (center of gravity) must be checked when the

model is ready to fly with the propeller and battery installed.

❏

1. Use a felt-tip pen or narrow strips of tape to mark the

balance point on the bottom of the wing 4-1/2" [115mm]

from the leading edge of the wing on both sides of the

fuselage.

❏

2. Lift the model, right side up, at the balance point you

marked on the bottom of the wing. If the nose drops the

model is nose-heavy and you must add weight to the tail. If

the tail drops, the model is tail-heavy and you must add

weight to the nose. In most cases you can relocate the

receiver and battery to achieve the correct balance without

adding additional weight. Our prototype models did not

require any weight to balance.

❏

3. If additional weight is required to balanced the model,

use small pieces of Great Planes stick-on weight (GPMQ4485).

If weight is required in the tail, it can be stuck to the top of

the wing next to the motor. If weight is required in the nose,

a slot can be cut in the nose where the weight can be

inserted. The slot can then be covered with tape.

❏

4. After placing weight on the model where necessary,

recheck the C.G. to confirm that it is correct.

Identity Your Model

No matter if you fly at an AMA sanctioned R/C club site or if

you fly somewhere on your own, you should always have

your name, address, telephone number and AMA number

on or inside your model. It is required at all AMA R/C club

flying sites and AMA sanctioned flying events. Fill out the

identification tag on page 19 and place it on or inside

your model.

Charge the Transmitter Batteries

Be certain the transmitter batteries are fully charged. Follow

the battery charging instructions that came with your radio

control system to charge the batteries.
