    Get your model ready to fly Important ESC and model information The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throt- tle stick is not in the low throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off position.
  • Page 12: Check The Control Throws

    Check the control throws The suggested control throw setting for FMS MODEL are as follows (dual rate setting): Tips: On first flight, fly the model in low rate. The first time you use high rates, be sure to fly at low...

  • Page 14: Center Of Gravity

    Check the C.G. (Center of Gravity) When balancing your model, adjust the battery as necessary so the model is level or slightly nose down. This is the correct balance point for your model. After the first flights, the CG position can be adjusted for your personal preference.
  • Page 15: Before Flying The Model

    Before flying the model Find a suitable flying site Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be required and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three football fields - a flying field specifically for R/C planes is best.
  • Page 16: Flying Course

    Flying Course Take off While applying power, slowly steer to keep the model straight. The model should accelerate quickly. As the model gains flight speed you will want to climb at a steady and even rate. It will climb out at a nice angle of attack (AOA).

  • Page 19: Esc Instruction

    ESC instruction Wires Connection: The electronic speed controller can be connected to the motor by soldering directly, or with high quality connectors. Always use new connectors, which should be soldered carefully to the cables and insulated with heat shrink tubes. The maximum length of the battery pack wires should be within 6 inches.
  • Page 20 Our ESC allows you to program parameters to fit your specific needs: 1. User programmable brake setting (we recommend using brake for only folding props applications) 2. User programmable battery type (LiPo or NiCd/NiMh) 3. User programmable low voltage cutoff setting 4.
  • Page 21 5. Timing setup: Automatic / Low / High. * Automatic – ESC automatically determines the optimum motor timing * Low (7-22 deg) – Setting for most 2 pole motors. * High (22-30 deg)-setting for motors with 6 or more poles. In most cases, automatic timing works well for all types of motors.
  • Page 22 Using Your New ESC Improper polarity or short circuit will damage the ESC therefore it is your responsibility to double check all plugs for proper polarity and firm fit BEFORE connecting the battery pack. Alert Tones The ESC is equipped with audible alert tones to indicate abnormal conditions at power up. If the ESC can't enter into working mode after powering up, it indicates that you have not setup throttle calibration.
  • Page 23 Built-in Intelligent ESC Safety Functions 1. Over-heat protection: When the temperature of ESC exceeds 110 deg C, the ESC will reduce the output power to allow it too cool. 2. Lost Throttle signal protection: The ESC will automatically reduces output power to the motor when it detects a lost of throttle signal for 2 second, a subsequent loss of throttle signal beyond 2 seconds, will cause the ESC automatically to cut power to the motor.
  • Page 24 ●Never use ruptured or punctured battery cells. ●Never use battery packs that are known to overheat. ●Never short circuit battery or motor terminals. ●Always use proper insulation material for cable insulation. ●Always use proper cable connectors. ●Do not exceed the number of cells or servos specified by the ESC. Wrong battery polarity will damage the ESC and void the warranty.
  • Page 25 Motor doesn’t work after powering up Check and verify that the ESC cable The ESC is unable to detect the the ESC. An alert tone with a single is connected to the Throttle channel normal throttle signal from the receiver beeping tone followed by a short on the receiver.
