I recently got an MT-4 so i need another receiver for a new car im building.

It seems like the RX471, 472, 481 and 482 all work it.

Am I right to assume the 481 and 482 are newer?

Should I just buy whichever one of the 4 i can find cheapest since I cant tell the difference besides no antennae wire?

47x series is with external antenna wire, 48x series is with internal antenna.

4x1 series is the basic racing receiver, 4x2 has the extended telemetry options.

Since Im fairly new and dont know what telemetry is im probably ok with the 4x1 series. thanks!

I don't use any telemetry functions so I specifically went with the 481's. For me the internal antenna on the 481 is a big selling point over the 471. I seem to remember them being nearly the same price.

For touring or pan car the 481 with the internal reciever is a nice choice however for almost anything else the 481 doesn't fit in many reciever boxes due to its awkward shape. The 471 is the best reciever in my opinion as I don't bother with any telemetry functions. All 4 of the receivers you listed are FH4 receivers which mean they all perform to the same latency/response figure.

thanks so much guys, now i can buy with confidence on them.
