FlySky GT3 radio RX question - RC-Monster Forums

simplechamp · 04:54 PM

I'm sure many of you have seen the FlySky GT3 radio. It is the next model after the FlySky GT2 (which is the same model as the cheap HobbyCity $20 radio, and supposedly the RX's are interchangeable). The GT3 is a more advanced radio than the GT2 or HC radios, with LCD screen, multiple model memory, drop down wheel, and all the adjustment features you would expect.

I decided to try this out because although my Nomadio works great, they are no longer being supported, and I want to have a cheap backup (there is a plastic part in the wheel mechanism of the Nomadio that is known to break). Also, I'm sick of buying expensive Spektrum RX's.

Now to my question, for anyone who has used the RX's (whether it be the FlySky badged ones or the HobbyCity ones): has anyone tested them running on 7.4V? The manual says 4.5-6V, but I was really hoping to be able to run 7.4V to power the HV servo in my truggy, and I'll soon upgrading to an HV servo in my buggy. Is it likely that an extra 1-1.5V could fry the electronics?

I think I'm going to go ahead and test one myself, since I bought a few extra and they are cheap anyway, but I wanted to see if anyone else has already run them on 7.4V. As always, thanks in advance for any help!

I know some of you guys bought the cheap HobbyCity 2.4Ghz radios to play around with, no one has tried 7.4V on the RX's yet?

Not really answering your question, but you could rig a servo adaptor so that the receiver gets 6v (via a simple 5-6v regulator IC), but the servo itself gets the full 7.4v.

Hey Simplechamp 6.5volts is the most I have tried so far.

Has the GT-3 in the past, absolute rubbish radio, the GT-2 was far better range wise and stability wise, but it was a basic transmitter, the GT-3 was trying to be a KO rip off but half the menus had no effect and if you changed settings for one model memory, it did it for all models!

I suppose I could, but I'm already pretty terrible at doing clean wiring jobs, so the less extras the better.

Since the receivers are more or less expendable I'm just going to test it myself, probably start at 6.6V since Bruce has run it there and ramp it up in .2V increments from there.

Guess I'll have to see for myself, you are the first I've seen reporting those issues, although I've only read a few other reports of people using it, but they were generally positive. I definitely won't sell my current system until I see first-hand what happens. I supposedly have the V3 newest version, so maybe they have fixed some of the firmware bugs? How long ago did you buy your GT3?
