I have made mention in the past, that I think one of the more revolutionary aspects of the noble, is also one of its most silly. Why have a removable second battery, if there are far more reasons to have it attached than not attached? Being someone that prefers the battery not attached I have done various things to ensure I don't have to attach it. And I think this is the pinnacle of that quest. An end cap with a micro usb b female plug. With this I can charge, do firmware updates, and would only have to slap on the external in an emergency if I had been neglectful on charging the internal battery. I personally think flysky should offer such an option.

Very nice job!!!
I totally agree with you!

I believe it serves as a portable USB power source for charging a cell phone, etc...

Indeed, it does. I'd be interested to know how many noble owners have made use of this feature. For me, personally, this is a useless feature. Honestly if I could have bought a noble with with only an internal, no external, I would have gotten along just as well.

Last night I had planned to swap the stock wheel on this to another one I had from a KO Propo radio and came to the disappointing realization that they are not compatible. Is the wheel adapter on this proprietary or is it compatible with other brands like Sanwa, Futaba, etc?

Mostly they are different, but even some different radios among the same brand have different wheel adapters at times, for some reason.

I have drawn several radio wheel adapters, trying to make like a universal package of adapters. It was a frustrating endeavor. I have printed several wheels just for nobles, so, 3d printed is an option if your looking to change up the looks.

MrOflam is the 3d drawing yours? Where can I download it to make it printed for my noble?
Can you share it by any chance?

Yes, I drew it. You can get it here if you like.

Thank you very much.. I really appreciate it!!

For me, it's a mostly useless feature as well due to the fact that I own two cell phones that utilize fast charging and the Noble's usb output doesn't offer fast charging. Charging a Note 10 Plus takes a long time at 1amp.

Unfortunately, this issue isn't exclusive to the Noble. The industry as a whole has not embraced fast charging capability on it's products. Why sell a nice $150-$300 battery charger that has a usb port that outputs 1amp? Don't want to pay the royalty fees for technologies like Qualcomm QC? Fine, then offer "smart charging" ports like the companies Aukey and RavPower do at a lower price point.

Right.

My experiance is a bit more simple. In 20-something years of owning cell phones, I have never found myself in a position that I need a mobile charging option. So, its not even something I care to carry around (even on trips/vacations).

I found a use of it..
Lets say that you have the bottom power bank fully charged and you want to store the battery for some time.. You can use your phone to discharge the battery to about half for storage..

Ok guys, I received today the replacement screen that Flysky send me to replace my faulty screen and indeed it was the screen tha had the problem.
Now everything works fine.
But, something strange happens now, the screen colors are completely different then the previous one and everyones else flysky noble nb4.

Is the new screens color like that or did something gone wrong during installation of the new screen.

Take a look at the pictures below and tell me what do you think??

Looks like you got an upgrade! Colors aren’t all over the place and look intentional. Very cool!

That's weird man!

Did you replace the screen yourself?

Kinda looks like a bad connection. Like maybe that ribbon cable isn't in there all the way.
