Firebat R/C Pusher Jet ARF (GPMA1400/1405)
Tech Note

Helpful tips to be sure your first flights with your Firebat are successful:

After assembly, go through the assembly sequence again to check your work and setup.

  1. Check that the stock propeller is on the correct way, with "printing" on prop facing the back of the plane. (NOTE: The optional propeller in the manual can be used for tractor and pusher models. As this is a pusher model, you need to turn the prop around backwards to use it on this model.)
  2. Check that the propeller pushes the air back towards the rear of the plane. If not, reverse the leads to the motor.
  3. Triple-check the balance point, make sure the balance is where it is supposed to be before flying.
  4. Make sure battery is charged the full 4 hours prior to the first flight when using the wall charger included with the deluxe version. Setting up your servos and motor will use some battery power, so, before your first flights, holding the model, run the motor until the electronic speed control cuts off the power. This will discharge the battery so you can let the pack cool, then recharge 4 hours before the first flight.
  5. Make sure the canards are set at neutral/centered per the instructions before flying, and that the leading edges move up when the elevator stick is pulled back on the transmitter.
  6. Check ailerons for correct movement.
  7. Do not attempt rapid climbs after hand launches. The Firebat is a delta wing model. Delta wing aircraft have a very high drag at low airspeeds. Allow the model to accelerate before climbing. Note that canard aircraft are stall resistant, not stall proof. The will not spin readily, but when they run out of airspeed, they need altitude and engine power to translate into energy to resume forward controlled flight.
  8. ALWAYS range check the radio system before flying, with the motor off, and also with the motor running.
  9. Remember, adding excess weight will affect the way the Firebat flies. Painting is an easy way to add weight. Do NOT add anything to your Firebat if at all possible.
  10. The motor and battery recommended for the Firebat will provide flight times of 5-10 minutes. Both the motor and battery will be hot at the end of this time. If a larger battery is used, it will increase the run time and could cause the motor to overheat. Be sure to allow at least 10 minutes for cooling between flights. We do not recommend a larger capacity battery for this reason.
  11. If your Firebat has poor performance check the voltage at the motor and the thrust. The voltage should be at least 7.5 volts with the motor at full power (be careful to avoid the spinning prop). An inproper battery, small wires or the ESC can cause low voltage. To check the thrust put the Firebat on a household scale wit the nose down (a digital scale is best). Note the weight of the model. Using care to avoid the prop, run the motor at full power and again note the weight. The difference is the thrust, which should be at least 9.6 oz. (300 g).
  12. Check the thrust angle of the motor. There should be no up or down thrust.
