This is the Sanwa / Airtronics M12S-RS FH4T 4-Channel 2.4GHz Radio System with an included RX-482 Telemetry Receiver. The M12S-RS is very similar to the M12S in terms of response and function, but is slightly more basic to make it a great sport transmitter.

Sanwa/Airtronics M12S-RS FH4T 4-Channel 2.4GHz Radio System
This radio is awesome! It has the same internal specs as the $500 M12S..the only thing different between this radio and the more expensive option is that it's extra drop down or angle parts, no chrome buttons..anything to add extra cost or tune ability is removed and it comes out of the box with the small wheel, drop down and 4AA battery tray...I bought the SANWA branded life pack and I was set, same speed and same tenability as the M12S..just chepaer..awesome radio.

Sanwa/Airtronics M12S-RS FH4T 4-Channel 2.4GHz Radio System
Amazing transmitter, and worth the money. I always wanted an M12S but couldn’t justify the price. When Sanwa released this radio I thought an M12 might finally be within my reach. I am so happy I spent the money, this radio has all of the good things from the M12S and still feels like a top shelf unit. I recently tried the Spektrum DX5R and the Futaba 4PV. Both were very nice and are worthy of mention, but I feel the M12S-RS is on another level. The build quality, feel, and performance are truly pro-level. My only gripe is the battery tray flops around inside the housing, so I solved this by cutting out two foam strips to use as spacers. This is an amazing radio, and if you can’t swallow $500+ for the M12S then give this one a look, you won’t regret it.

Sanwa/Airtronics M12S-RS FH4T 4-Channel 2.4GHz Radio System
This transmitter so far is amazing. Very adjustable and feels great. Whatever you will run with this, you will certainly be able to set it up as you would like. Also would like to say Amain was amazing!!! It is on the heavier side as far as transmitters go but I prefer that!

Sanwa/Airtronics M12S-RS FH4T 4-Channel 2.4GHz Radio System
I was a bit surprised with the size and weight of the transmitter. Not overbearing, but a larger handful.
Operation is getting all of the options fine tuned to your liking.
It takes some time to get setup, but still a learning curve if you are new to this level of control.

Sanwa/Airtronics M12S-RS FH4T 4-Channel 2.4GHz Radio System
I have owned a number of different radio systems, prior to purchasing this Sanwa, I was running a spectrum. I was annoyed by its cheap feel, the glitching w/certain brand servos--it was ok, but I didn't know what I was missing.

I dived in to the high end w/Sanwa, based on reviews. It came down to Futaba and Sanwa in the end. I was not disappointed. This radio system has far more than I use or will ever need, but have continued room to grow. Great quality, Competitive priced. Quality feel--zero complaints with this unit. I realize now, that I could have gotten away with purchasing a MT44 and still had everything I needed, but exceptionally happy with this as I got it on sale, with coupon, and Amain points--awesome purchase. Awesome system.
