Rudder-to-throttle mix: (HELI) adds throttle to counter the added load from increasing pitch of the tail blades,
maintaining a constant head-speed with rudder. (This is a minor effect and is not critical in most helicopters.) Not a
preprogrammed mix. See Programmable mix.
Rx: receiver.
SAFE MODE: feature in snap roll programming that does not allow a snap roll if landing gear is lowered. See Snap roll.
Sailplane: glider, non-powered model aircraft type. See GLID / MODEL TYPE.

SWASH AFR: (HELI, CCPM types only) adjustment of the travel of all servos involved in the particular control’s

auxiliary control such as flaps from the stock dial to a switch or other location. See AUX-CH.
Synthesized module/receiver: The 9C is compatible with the R309DPS Futaba synthesized receiver that can be used on
any 72MHz channel. There is not a synthesized transmitter module that is safe/FCC certified/approved for use with the
