Introduction G7000T Indicator LEDs JR’s latest gyro, the G7000T, utilizes a new state-of the-art Silicone Ring Sensor for outstanding holding power and drift-free operation. The G7000T offers extreme tail lock holding power, and is designed specifically for helicopter use on the yaw (rudder/tail rotor) axis only.
Mounting the G7000T Metal Shield Plate for SRV Gyro (Option) Be sure to thoroughly clean the G7000T’s mounting area and the helicopter’s mounting location with rubbing alcohol prior to attachment. This Shield Plate alleviates the potential for electromagnetic noise caused by devices such as servos, electric motors, ESCs, etc. Note: Never install/mount the G7000T sensor directly to bare wood as it is possible for it to loosen during flight.
Connections (1) JR 8700G “Digital” Servo PCM 10 Connections (2) Connection Port 4 (3) PCM Receiver (4) G7000t Gyro Sensor 3 (6) White Connector– Connect to AUX channel from which you want the gain to be adjusted. (7) Connect SELECT to channel to which you would like the modes (Tail Lock/Rate) to be adjusted from. (8) Receiver Rudd – Connect to the Rudder (Tail Rotor) channel of your receiver.
Radio Type Polarity Connections Final Connections Please refer to the following polarity color chart when connecting the JR® G7000T to a brand of radio system other than JR. Please note that if the system is connected incorrectly, the G7000T will not function, but no damage will occur to any of the radio components. After successful connection, secure the gyro to the servo connection with a small piece of tape to prevent possible disconnection during use. Connect the JR G7000T Gyro to your radio system.
Transmitter Neutral Settings Gyro/Servo Direction and Compensation Before turning on the power to the G7000T, please first make sure that all Rudder and Sub Trim settings in the transmitter software have been reset to a 0 default. Please also make sure that all Revolution mixing has been removed, unless you will be using the G7000T in Rate mode. Note: No Revolution mixing can be present while using the G7000T in Tail Lock mode, as severe neutral changes will occur.
Servo Travel Adjustment with the Travel Limiter Pot The G7000T features both Left and Right manual servo travel limiter pots located on the end of the Amplifier unit as shown in the diagram. This manual setting allows you to use a full 150% travel value in your radio setup for the best resolution, while being able to reduce the physical travel of the servo in each direction to remove any tail linkage binding.
Tail Lock/Rate Mode Selection via AUX Channel (continued) TAIL LOCK Indicating Lamp Green: Tail Lock Mode Red: Rate Mode TAIL LOCK Mode and Strength As you can see from the diagram below, the G7000T is designed so that if assigned a Travel Adjust value of 11–150, the G7000T will be in Tail Lock Mode (Green LED). The value within this range can be altered, and will increase/decrease the strength of the Tail Lock function.
Gyro Gain Adjustment Additional Notes As mentioned, please use the following gain values as a starting point, and adjust these values as needed during test flights for best performance: Hover: 65%–80% Stunt: 40%–55% Please note that if you can run more than 95% gyro gain in Hover mode, it is suggested that the servo arm control ball position be moved out 1 hole position for improved performance.
