About M12S Super Response Modes:
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.

About Telemetry Support: The included RX-472 2.4GHz FH4T Super Response SSL receiver does not feature full Telemetry support (e.g., Temperature data and RPM/Speed data). Full Telemetry capability is supported only when used with a Sanwa Super Vortex series ESC plugged into the SSL slot. This is due to the fact that full internal Telemetry support slows the Response Time of the receiver and Sanwa chose to include a receiver that will allow you fastest Response Time possible for competition racing. Full Telemetry support requires the use of an Airtronics or Sanwa 2.4GHz FH4T Telemetry-capable surface receiver (RX-461, RX-462) or SSL-compatible ESC (e.g. Super Vortex series ESC). Steering and Throttle Output and Lap Times can still be viewed when used with non-Telemetry capable receivers.

Sanwa/Airtronics M12S Super FH4T 4-Channel 2.4GHz Radio System
I got one of these to replace my DX4R, as it was always glitching on me, especially indoor racing. The first time I used it there were a lot of things to get used to. I had to have help with understanding it. Then when I was racing with it I really felt connected. I usually run last in most races as I am not that good, but this radio makes a big difference. My first race was an eye opener as something clicked and I started really moving. My second time to race this I placed fourth in the E-Buggy B main and was one lap back from the leader, by far the best I have ever done. T say the least I am very excited with this radio. Now I see why the pros use it. Update: still loving this radio. Best choice ever!

Sanwa/Airtronics M12S Super FH4T 4-Channel 2.4GHz Radio System
I was in the hobby years ago. Started with Futaba, got a little better Futaba, finally stepped up to an M8. It was so much better and easier to use. 15 years later I go to get back into RC. I looked at the 4PX. It just didn't feel like a 600 dollar radio. Opted for the M12S. Glad I did. It has the same locked in feel was super easy to bind, and programming was easy and intuitive. I have now owned the M8, M11, and the M12S. They just feel like quality. I am sure the 4PX is a great radio but for me the M12S was the right choice. Not one regret about this radio.
