The carbon fiber handle made the selling price higher and seems to me irrelevant to the design

And specification wise, it may not as fast as m12

This is another shop in Japan they export 4PX, available end of June

Anyone know about The 4PX three different receiver for use

Same as previous version 4 pk, it offers receivers with and without physical antenna, and also the latest receiver with telemetry function, as Sanwa 472 receiver

curious on the cost of the telemetry sensors.

The response of T-FHSS system in 4PX is optimized and 30% faster than 4PKSR.

I am a bit confused about this statement . Does this mean that if you use the cheaper t-fhss receivers that they are now faster than futabas FAAST system? Or is response and latency two different things?

Does anyone know if 4px will support also R604FS receivers? I know its not specified in information data.

The details that you're looking for are on Page 3&4 of this thread

The 604fs is a FASST C2 receiver. So it should work just fine according to the specs.

The lack of C1 support is really disappointing, most of my receivers are ex 3pk FASST so may have to stay on the 4pks a while longer

Yep

Based on Futaba's website.

604FS should work along with the 614's. All my 603FS are no bueno, but with the cost of some of the FHSS and TFHSS receivers, it's probably not a deal breaker. Means I personally will have 4 compatible receivers and 4 non.

Was looking at upgrading my 4PK to the 4PKSR, but this is probably a better long term option.

Have you ordered from that website?

Problem with ordering over seas is if you ever have an issue and it needs warranty work, guess where you are sending it? back over seas.

I always ordered my parts and things from Japan. Almost one every quarter year for the past 10 years. Super reliable.
But this time, I ordered a m12 40th anniversary version instead.
To me, the color monitor seems nice, but I more look into the response and speed.
I love to see and touch the real thing first. If it proves to be faster, spec wise, I will buy this
