  • If you're using Analog servos in your model, DO NOT use the SHR or SSR Channel Response Mode for those channels. Use the NOR Channel Response Mode with Analog servos. Using SHR or SSR Channel Response Modes with Analog servos can result in poor performance or even damage to the servos and/or the receiver. SHR and SSR Channel Response Modes should only be used with Digital servos. While the SHR Channel Response Mode can be used with any brand of Digital servo, the SSR Channel Response Mode should only be used with Airtronics or Sanwa Super Response SRG Digital servos. Not all ESCs are compatible with SHR or SSR Channel Response Modes. If your ESC does not operate correctly, change the Throttle Channel Response Mode to NOR. SSR Channel Response Mode is only available when used with compatible FH4 or FH4T Super Response receiver.
  • Please note that the Nominal Input Voltage is 4.8 to 7.4v, therefore this transmitter will not be compatible with 2S LiPo. If users wish to change the AA Sized battery tray to a battery pack, please choose a battery pack which is within that voltage range.
