Hello Charles, All,

Your FS-iT4 is a first generation.
Mine is a second generation.
The firmware is sure for a second generation of FS-iT4.
The latest version is 1.02US 07-12-2013

Do you have contacted Flysky by mail ?

Do you have configured your FS-iT4 to "FS-iT4 emulator" in sub menu called "USB menu" ?

Does your FS-iT4 is it discovered by the update software on windows ?

Note: Until you click on the "update" button nothing happens.

Do you really need to update your device ?
If you want to be secure, don't update yours FS-iT4....

Regards,
Renaud

i need to up date to bind more than one model at a time

Have you tried? The multi bind issue is a hardware issue not a software one.

When I installed my chip I was all set. No FW update needed.

I got the firmware update for version 1.01-US. 22-01-13 from Fly-Sky. Here is the link provided below. I have not used it yet, still waiting to get the IC chip solder on

Hi guys,

do you know if the 4ch rx that comes with the radio, can handle a 2 lipo?

Yes it can, if your running HV servos

i have hv servos. so i can plug directly to the rx the 2s lipo? is for a 1/5 scale rc car.

You will need to make Shore your power switch has the right connectors (deans ie) to plug the Lipo too. Haveing a glitch buster will help regulate the voltage.

The manual states 6.5v max for the receiver. But, it can take the 2s lipo???

No one has used the IT4 receiver with a 2 lipo?

I just picked up a Fly Sky iT4 radio package in shiny orange chrome colour from a local seller and included with the radio is a Fly Sky FS-GR3C receiver. I can't seem to get the transmitter to bind with this receiver. I am wondering if perhaps this receiver just isn't compatible with the iT4 transmitter. Can anyone help?

Sorry to say but that Rx is not compatable with the it4.

Thanks.

Steve,

Don't own this radio, but from researching and reading thread, I think your older AFHDS receiver should work.

If your transmitter is the latest ic chip hardware and firmware, there should be a option in the transmitter to switch from afhds2 -- afhds.

Change setting to AFHDS and try binding.

Hope this helps
Al

The iT4 Transmitter will bind to the FS-iR4 AFHDS2 Receiver (what came with my iT4 TX). Hope this helps!
