Required Parts

Required Tools and Adhesives

Felt-tipped pen Ruler

Balancing stand (optional)

An important part of preparing the aircraft for flight is

properly balancing the model.

CAUTION: Do not inadvertently skip this step or

property damage and injury could occur.

 1. Assemble your model in preparation for flight,

making sure the wing is on securely and the motor

battery is installed as instructed in this manual.

 2. The recommended Center of Gravity (CG)

location for your model is 2.75 to 3.00 inches

(70.0 to 76.0mm) back from the leading edge of

the wing as shown with the battery pack installed.

Mark the location of the CG on the top of the wing

with a felt-tipped pen.

 3. When balancing your model, support the plane

upright at the marks made on the bottom of the

wing with your fingers or a commercially available

balancing stand. This is the correct balance point

for your model. Make sure your model is assembled

and ready for flight before balancing.

Balancing Stand

Adjust the motor battery as necessary so the model is

level or slightly nose down. This is the correct balance

point for your model. You should find the CG to be

very close with the battery installed as shown in this

manual. Mark the location of the battery on the battery

tray using a felt-tipped pen so it can be returned to this

position if it is removed from your model.

After the first flights, the CG position can be adjusted

for your personal preference.
