Pre Arm sensor modification

Hi,

Having trouble arming my unused Quanum Nova quad. Using a DX9 transmitter and AR610 receiver. In ‘Flight Data’ mode on MP I get the ‘Disarmed’ flag and a msg underneath declaring ‘PreArm: Check FS-THR-VA’. No other message. Need help to
on what I need to change, and where to locate the parameter. Thank you

Check FS_THR_VALUE : the radio failsafe pwm value has been set too close to the throttle channels (i.e. ch3) minimum.

Thank you, Jim. Will reset.
