To up date the soft ware do u need to use a SIM card . My radio glitched the last time I used in model two ,, I have no problem in model one tho . But befor I up date the soft ware I'm going to try it again in the spring when nitro season starts again to make sure everything is good with the Truggy befor the season stArts

A MicroSD card is required for software updates or backing up/transferring of model settings between 4PX transmitters.

Having problems binding fr sky tfr4 receiver, do they work with the 4px?

If so any suggestions as to what I am missing

Thanks

C1 receivers do not work on the 4PX

Don't know if this question has already been asked, so please excuse my ignorance if it has. In the manual it says there is an optional steering wheel angle adapter but does not show a part number for it. Can someone provide that number and has the part been released for sale yet?

Are the glitches with FASST or FHSS receivers?

most have been reported with T-FHSS

In the 4px if I want to use other model memory to setup different track with the same car do I have to rebind the receiver every time I am switch model memory for different tracks?????

Yes.

This spectacular the 4PX, but would have to come up with a better receiver ... like R614FS

Also include the battery (LiFe) as the Japanese version ... and like his previous: 4PK, 4PKS, and 4PKS-R

No? I routinely forget to change models, and never had a problem with receiver binding to the radio in the wrong model.

The issue might be if it's electric, the esc may not have the exact same neutral points.

Maybe if using telemetry RX, you might need to bind the initial time in each respective model so the telemetry ID is set properly for that model. I doubt this matters for the non telemetry RXs. Once bound to TX, they work on any model memory of 4PX.

Feeler:

May sell my 4PX Carbon wrapped... 2 x rx box manual charger life.

PM me with serious offers....

Radio works great... debating keeping or sell due to time on track for 2015...

Where did you get the carbon fiber wrap?

The fasst and sfhss recievers work with any model once they are bound to the radio, but the newer tfhss receivers are bound only to a specific model in the 4px. If you use an older style receiver like the fasst or sfhss then you can use multiple models set up on the same car without rebinding each time you switch.
