If it's like the NB4 you update the receivers from the transmitter. The receiver firmware updates are included with the transmitter firmware.

That was the hint I needed. Found a video on youtube how to update the firmware on the NB4 and the iT4S works the same way.
Unfortunately it will not let me post the link here

Thanks!!!

Hi, got this all works fine with rx included with tx but have now bought the 4 channel svc rx to use.
have latest firmware on tx and rx but cannot get any output on channels 1 and 2 but seems ok with servos in channels 3 and 4 when operated by sw1 or other switch. Doesn't matter if svc is selected on tx or not and moving rx doesn't cause servo to move either as it should if svc turned on. Anyone else had same issue and resolved it. Saw someone mention it on another group but they have no solution. I have already sent rx back for new one in case it was faulty but still same issue.

Hows the latency on this transmitter? Is it better than flysky gt3c and gt5? And also can u adjust gyro settings with this one?

Thinking about getting this or the gt5.

Thanks to anyone who would answer.

Does anyone have the latest US firmware for this Transmitter? I have tried the firmware from their site, but the transmitter is not recognized when in firmware mode. I am currently running version 1.0.2.0 and wouldn't mind updating if there is a new version.

anyone have a dead fs-it4 for parts? I need a wheel adapter.

I have this FS-IT4 radio that I have been keeping stashed away. It was pulled out two days ago to be used on VRC to see how it would work. I really like the touchscreen features, the weight and the overall performance upgrade it gives me over the Spectrum DX3 v.1. My only nick that I can report tonight is the steering wheel stops. The wheel goes right and left, but it now has a broken part or something slightly jamming the end of the physical motion of the wheel. If I can explain in a different way. The steering wheel turns, and it feels like there is a bump stop before the bump stop. I was wondering if this was common for these radios. I want to know if the transmitter is so delicate, I should watch for more damage. Is it something that just needs a breaking in period? This triggered an alarm to watch for cheaper equipment. Although the FS-it4 was outperforming the DX3 at the time, the durability of the steering mechanism may be in doubt.

my post above yours was looking for the part that has the stops on it. So.. yeah. if your part is broken, you can print one that I created.

still a big hassle though. If yours breaks and you dont want to bother with it, PM me.
