IMPORTANT INFORMATION REGARDING WARRANTY
SAFETY WARNINGS AND PRECAUTIONS
Please read our Warranty and Liability Limitations section before building this product. If you as the Purchaser or user are not
prepared to accept the liability associated with the use of this Product, you are advised to return this product immediately in
new and unused condition to the place of purchase.
LOW VOLTAGE CUTOFF
Protect yourself and others by following these basic safety guidelines.
1. This manual contains instructions for safety, operation and maintenance. It is essential to read and follow all the
instructions and warnings in the manual, prior to assembly, setup or use, in order to operate correctly and avoid damage or
serious injury.
2. This model is not a toy, rather it is a sophisticated hobby product and must be operated with caution and common sense.
This product requires some basic mechanical ability. Failure to operate this product in a safe and responsible manner could
result in injury or damage to the product or other property.
3. This model must be assembled according to these instructions. Do not alter or modify the model outside of these
instructions provided by Flex Innovations, Inc. as doing so may render it unsafe and/or unflyable. It is your responsibility to
ensure the airworthiness of the model.
4. Inspect and check operation of the model and all its components before every flight.
5. If you are not an experienced pilot or have not flown a high-performance model before, it is recommended that you seek
assistance from an experienced pilot in your R/C club for your first flights. If you're not a member of a club, the Academy of
Model Aeronautics (AMA) has information about clubs in your area whose membership includes experienced pilots.
6. Keep the propeller area clear from such items as loose clothing, jewelry, long hair, or tools as they can become entangled.
Keep your hands and body parts away from the propeller as injury can occur.
7. Never fly in visible moisture, or submerge the airplane or any of its electronic components in water. Permanent damage to
electronic components may occur, or corrosion of components may lead to intermittent failures.
Li-Po batteries have a nominal (rated) voltage of 3.7V per cell, and fully charged, reach 4.2V per cell. Batteries are designed
to be discharged below the nominal voltage, however, if they are discharged below 3.0V per cell, damage will occur and the
pack will lose capacity. For best long term battery life, set a timer and land after a time that leaves approximately 15% of the
battery's capacity remaining.
Low voltage cutoff is a feature that is built into the ZTW 50A ESC that is designed to protect the connected battery from being
discharged too far and causing permanent damage to the cells. Circuitry within the ESC will automatically detect when the
input voltage from the battery pack reaches below 3.15V per cell (average) and will remove power to the motor, but still
deliver power to the servos so that a safe landing may be made. If the motor begins to lose power rapidly during flight, the
LVC has sensed that the total voltage of the pack has dropped below 3.15V per cell average, and the airplane should be
landed immediately.
