TELEBEE HEADING LOCK GYRO

REPRINTED FROM ROTORY MODELER MAGAZINE

You will need to make three connections, first - you’ll plug your tailrotor servo directly into the Telebee controller, where it designates “servo”. The next connection (using the two supplied male-to-male connectors), you’ll plug in the “RX-1-4” into the tail rotor connection on your receiver. Finally, plug in the “RX-AUX” to an Aux. channel on your receiver, preferably the “channel five” (gyro channel). Next, the ATVs gain is set for channel five. I used 60% to start off with. As you switch the Aux. channel to over or under 50%, it also changes the mode of operation. This way, as you flip the gyro (channel 5) switch on the transmitter, it changes the mode of the Telebee GR701 from standard operation of a rate gyro to the “Heading Hold” mode.

For most, setting the gain of the gyro is somewhat confusing. The gain of both; Normal and Heading Lock modes, are adjusted by changing the ATV percentages of the Aux. channel that you selected. Keep in mind that your Aux. channel is divided into two parts, 50% up is one mode, and 50% down is the other.

After you select the Aux. channel that you’re going to use, go to the ATV setting on your radio and adjust the ATV of that channel from the default of 100% to 60% in both the up and down positions. After you trim your machine in the air, if you want to add more gain, then adjust the ATV gain by increasing the value more than the original 60% that you set. Let’s look at an example, if you flip the Aux. switch “up” for Heading Lock mode, and you want to increase the gain to make the tail more stable, then you’ll adjust the ATV gain that corresponds just to that portion of the channel (up or down). On some radio systems like the JR PCM 10, when you adjust the ATV of the channels, as you flip the Aux. switch, it highlights or activates just that portion of the ATV that is being adjusted.
