Safety in Flying
This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme maneuvers. It
should only be operated by a competent pilot in a safe area with proper supervision.
ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to fly.
NEVER fly over an unsafe area, such as a road or street.
Never fly too close to yourself or spectators.
Never run your motor inside a house or building with the propeller attached – Remove the prop for safety.
Required Items

Before Starting Assembly
Examination
Unpack your airplane and examine the components. Check for damage of any kind. If you see any damage,
please contact Value Hobby immediately.
Covering
Your airplane was packed in plastic at the factory without any wrinkles in the covering. You may notice some
wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane out to the
flying field. These wrinkles are the result of wood shrinkage and/or expansion. Balsa wood changes size and
shape slightly as it is exposed to varying humidity in the air. This is a natural property of balsa wood. As your
airplane adjusts to the weather in your part of the world, wrinkles may appear and disappear. Wrinkles may be
removed with the gentle application of heat to the covering material on your airplane. The best tool to use is a
hobby heat gun. Apply the heat gently: the covering material will shrink as you apply the heat, and this will
remove the wrinkles. BE CAREFUL! Too much heat applied too quickly can damage the covering, either by
causing it to pull away from the wood at seams and corners or even by melting it. The covering will shrink at low
temperature with patient application of heat.
Wrinkles in the covering DO NOT affect flight performance.
Remove the canopy before attempting to use heat on your covering! The canopy is made of thermo-activated
plastic and WILL deform with the application of heat. Do not apply heat to the canopy.
If you need to clean your airplane, we recommend using a damp towel. The paint used on the canopy and cowl is
not safe for all cleaners. In particular, DO NOT use alcohol on these parts, it will remove the paint
