measured at the wing tip
Warning
Do not skip this step!
2. Balance the 35cc EXTRA 300 ARF-QB without
fuel in the tank with the batteries installed and
ready to fly. The engine, radio, servos, and bat-
tery you use will determine the final weight and
locations of equipment. Try to balance the
model by moving the battery and receiver before
adding any ballast.
Note: Model should sit level when lifted from the
wing tips
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. Use the widest part of the aileron as shown to
measure the aileron throw in inches.
