CSM 720 Gyro
Hi all , have a Fury 90 with a CSM SL-720 and a Futaba S9254 have a spare 6v pack to use , I know the servo is rated to 4.8 v so I put a JR step down lead between the servo and Gyro but all I get is a hum and no movement of the servo at all , tried the step down between the battery and RX and it worked , went back to 4.8 v pack all worked fine , my question is why won't it work between the Gyro and Servo , is the Servo not compatible or did I select the wrong frame rate for servo ? ....

The 9254 will work with any frame rate the 720 puts out (330 max?) but will only work on standard 1520 pulse width so check you have that set correctly.60% of the time, it works every time!

By default the SL720 is set to 1520us pulse width and 250 frames per second compatible with all standard pulse length digital servos.

To change the settings for a narrow pulse width or a different frame rate requires use of the PC interface facility.

The question is did it ever work?
