Center of Gravity

1. Warning, do not skip this step!

The recom-

mended CG is 3 1/4” back from the leading edge

of the wing at the wing tip.

2. Balance the Extra 260 without fuel in the tank

with the battery installed and ready to fly. The

engine, radio, servos, and batteries you use will

determine the final weight and mounting loca-

tion of equipment. Try to balance the model by

moving the battery and receiver before adding

any ballast.

3. Start at recommended CG until you are comfort-

able with the flight characteristics of the aircraft.

You may find this a bit nose heavy at first but

that is fine to start with. After you are comfort-

able adjust the CG to suit your flying style in

small steps, especially when shifting the CG to-

ward the tail. Move the battery or add small

stick on weights to the nose or tail as necessary.

4. For aerobatic flying a more aft balance point is

better. For smooth sport flying a more forward

CG is better. An aircraft that is too nose heavy

does not fly well and is difficult to land. A tail

heavy aircraft is uncontrollable and will likely

crash.

Control Throws

1. The amount of control throw should be adjusted

using mechanical means as much as possible and

then electronically with the radio. The control

throws are shown in degrees and inches of de-

flection measured at the widest point of the con-

trol surface for both low and high rates.

2. Aileron throw measured in inches
