A range check must be performed before the first flight of a new model. It is not necessary to do a range check
before every flight (but is not a bad idea to perform a range check before the first flight of each day). A range
check is the final opportunity to reveal any radio malfunctions, and to be certain the system has adequate
operational range.
1. There is “Power Down Mode” built in for doing a ground range check. To activate the “Power Down
Mode” make sure the transmitter is already ON an press the “PDM” button on the right upper panel of
the transmitter. The Green LED will turn off to indicate the PDM is working. During this mode, the RF
power is reduced so the range test can be performed.
2. Walk away from the model while simultaneously operating the controls. Have an assistant stand by the
model and signal what the controls are doing to confirm that they operate correctly. You should be
able to walk approximately 30 - 50 paces from the model without losing control.
3. If everything operates correctly, return to the model. The “Power Down Mode” continues for 60 seconds
and after that the power will go back to the normal level and the Green LED will come back on. To exit
the “Power Down Mode” before the 60 seconds, press the “PDM” key again.
WARNING: NEVER start flying when the “Power Down Mode” is active.
