Yea taking the battery off feels bad. If you think you're almost breaking it, apply a little more force and it'll come off, not the best feeling.

I've got a relatively similar control setup to you, I just put my brake D/R on a thumb dial instead of the proportional one so I don't have to set it up again for every model or if I accidentally hit it even if the radio's off.

The battery is hard to remove by design if it was easy to remove now that could be a real problem and I see no need to remove it.

I finally figured out how to get the battery off. Held the controller upside down in my left hand then pressed down as hard as I could with my right. I heard it click and it slid off. I figured it would have had a release button somewhere. And I changed my brake rate to the thumb wheel, make more sense.

Agreed. But being the owner of my radio, I'm gonna check all the bits and bobs out. It's how I learn the component. And how I learned to not remove the battery (no plans to run without it, just inspections).

Got my noble on Sunday and absolutely love it so far. Definitely a big step up from the random old traxxas I was using previously.

With that, I am sure I will need to be much more gentle with this radio than the old piece of plastic that I would just throw in a bag if I wanted to take it somewhere. So… I went to harbor freight this morning and picked up this case for about 30 bucks and it is amazing for this use! Even has room for a couple batteries as well!

I'm going to have to start walking back my praise of the NB4 after what happened to me last night.

Yesterday I was charging the radio via the USB port. In the evening I unplugged the radio so I could drive one of my cars around for a bit. The radio would not turn on after re-charging. It didn't matter how long I held in the power button, the unit would not power up and was completely unresponsive. I really thought charging the radio had somehow bricked it.

I thought perhaps there was an issue with the internal battery since the issue appeared after charging so I took the radio apart. Once I got to the battery I checked it with a DMM and it measured 4.08V. Nope, not the issue. I tried removing and re-inserting the battery to see if that would maybe cause a hardware reset or something. Nope. Didn't work.

While trying to think of what to do next, I noticed a tiny little pushbutton that is normally hidden by the rubber grip on the back. I figured It might be some kind of hardware reset switch and tried pressing it. Whatever the button did worked - after I pressed it I was able to get the radio to turn back on.

I now find myself seriously questioning the reliability of this radio. It took me a good 20 minutes to get the radio working again. Thankfully this happened to me at home when I was just going to drive around for a bit of fun but if this had happened to me at the track right before the main it would have completely ruined a race day.

I've never had a radio simply refuse to turn on. This is pretty disappointing and exactly the kind of thing I was worried about after a bad experience with the GT3B years ago.

Super annoying for sure but you figured it out and it didn't ruin your race day so no need to bash the remote things happen I had a race this weekend brand new ESC crapped out on me didn't get the race much but things happen and there's always a next time can you share the picture with us thank you

Been running this for 1 year now after running a MT44. I bought it telling myself I would buy a 7ox or m17 if I didn't like it haven't found a reason yet, except one small one creeping up. I run open/expert classes in Socal 1/8 offroad and 1/10 indoor, and some onroad.

Originally was worried about the wheel moving, not a concern a year later still very stff to move right to left.

Range, hasn't been an issue on and offroad 1/8 and 1/10, range is better then my vision off the track

Menu, interface, no compliant, easy to adjust anything pretty fast.

Model memory, I'm at 19, my wife will be happy about that because I have one slot left, but would love to see that bumped to 30+

FW updates, went smoothly, no issues.

Mixing /buttons, pretty easy to assign and program for my two speed crawler and 4ws cars.

Screen, you cannot see it in bright light, not at all, but i don't see a way around this without a different technology for the screen. love the touch screen, not going back to dials an buttons, ever if i don't have to.

Still haven't found a reason for a 7px and wrote off the M17 because of the lack of touch screen, happy to keep running the NB4.

If you got a GT5, Radiomaster, or DX5C, you'd basically have a very reliable, straightforward radio. Runs on AA, never going to have a charging issue. But, if you start shopping for the feature set of a radio that does everything the Noble does, you're going to be looking at radios that cost much more and can also have internal charging issues and brick for whatever reason. Before settling on the Noble, I ran across numerous threads of the high end Spektrum or Sanwas also having some quirks or issues. I figured at least with the Noble, I could afford to replace it if something unrepairable occurred and I'd still have enough money to buy another and still be ahead. I guess a big difference is support you get with those other expensive high end brands, there's certainly value in that.

To be clear, I would be just as disappointed and upset by a failure like the one I experience last night regardless of the brand. The radio was working fine, I plugged the radio in to recharge it, and when I unplugged the radio it was bricked. Something like that would make me hesitate to use or recommend any radio regardless of brand. And while I have no experience with similar radios from other brands, those radios having similar issues would not make me any more forgiving of FlySky. A radio bricking itself like mine did is still pretty bad even if other brands have the same problem.

Thanks for sharing the solution. Sounds like an easy fix. Were your model memories retained?​​​​

Have now had mine for over a year with 0 issues even after dropping it once (I now use a lanyard) and I seriously doubt I will go back to Futaba or Sanwa after owning the NB4 it just suits my wants and needs better than either of them ever did.

Thankfully yes. I was afraid I'd end up having to re-bind my receivers but fortunately that wasn't the case.

For reference here is the button that seems to have fixed my issue. It is hidden underneath a grip that is supposed to be user swappable, but you can tell by the damage done to the casing it's not exactly an easy thing to do. I had to use an exacto knife to pry the rubber up just enough to get a screwdriver between the case and the rubber grip and it took a disconcerting amount of effort to pry that grip off. It felt like I was going to break something. I'm not sure who thought that was a good idea for something that is supposed to be user swappable, but that goes back to what the other poster was saying about the battery bank that's supposed to be removeable but also feels like your going to break the radio getting it off. It's certainly a weird choice on FlySky's part that makes the user experience less enjoyable.

Someone in a facebook group shared a trigger guard they had made out of an item they bought, then glued to their NB4. I thought it looked cool, so I made a couple of my own.

The first one attaches at the top, where you might see several of the gopro mounts, and then at the base of the handle by going around it and bolting it through.


Then I thought I would make one thats much more custom to how I use the noble. I never use the external battery, and such, made the second version attach to the external battery port at the bottom of the grip.

Holy crap look at that! I had noted this mysterious unused button like 2 years ago now. I have 3 nobles (1 is for parts), they all 3 have this button on the PCB, but no way of using them from the outside of the case (see attached image). Yours must be newer than mine, and they must have had some kind of update. Cool!
