    Hi guys,

    Just need some advice on a servo. I bought a ALZRC DM1531T coreless servo for rudder on Devil 450. I have plugged it in to a Spektrum AR7000 receiver to check centre so I can set servo arms. Problem is it will not respond. I had success with the 3 DS452MG servos which worked fine.

    I just read the description on this servo and the last line states: Note: narrowband receivers use the steering gear can not be directly inserted, can only choose to work through 760us gyro!

    So is it the case that it is not working because the AR7000 is a narrow band receiver? Don't know what a narrow band receiver is. I have the tzg380 gyro which i assume will be compatible??

    Is there somewhere on this forum where I can find setup procedure for the tzg380 gyro. I cannot see anything when searching??

    Troy

    It appears that setup menu step C needs to be red to work with 760us. So it should work without issue.
