9XR PRO - better gimbals

Post by playlet » Tue Dec 09, 2014 12:02 am

Hi!

Can someone suggest what replacement gimbals can we use for this TX? Stock gimbals are bad. On my TX, rudder stick didn't last 4 months and I had to ask for the replacement. The replacement isn't good enough either.

Aurora 9, Taranis? Other? Which would be the best no matter what mods are needed to install them...

Thanks!

Br, Ivan

Until now there aren't any known replacements apart from the original ones HK sells :(

I have some 9X gimbals that I'm going to use on some experiments with hall sensors. Maybe a nice winter project. A user from this forum already replaced the throttle pot with a hall sensor and a magnet and it apparently worked well.. Will have to find the thread..
Sorry, this isn't the answer you wanted :(

Any answer is better than no answer. Thank you for that.

I wanted to open this thread to encourage people to publish what they did to mod their gimbals because we could all benefit from their experience. There are posts across forums about people changing their gimbals but there are no detailed instructions on what they did exactly and how they set it up...

HI playlet,

Sorry to here about the problem, I believe the Aurora 9, Taranis and stock 9x Radio Gimbals will not fit.
The 9XR and 9XR Pro Case and Gimbals, are smaller then the Stock 9x and Taranis Case and Gimbals.
Other than purchasing replacement Gimbals, ...... the only thing I can suggest is to: (1) trying to repair the bad Potentiometers,
(2) purchase the mode 2 left side Gimbals set from HobbyKing try replacement it again or replace the bad Potentiometer in it.
Note: 3 of the 9XR Gimbals Potentiometers are different from the throttle Potentiometer.

HobbyKing Replacement 9XR Gimbals: mode 2 left side: (http://www.hobbyking.com/hobbyking/stor ... ode_2.html)
and the right side mode 2: (http://www.hobbyking.com/hobbyking/stor ... ode_2.html)

Check out this post for more info about these small Potentiometers that are used in these stock 9X and 9XR Gimbals: (http://openrcforums.com/forum/viewtopic.php?f=95&t=2974)
and see (http://openrcforums.com/forum/viewtopic ... 150#p54150)

I have not seen anyone who has done or found different Gimbals to use to upgrade the stock 9XR and 9XR Pro Radios.

If you are able to verify that the problem is in the rudder potentiometer itself and that it is receiving the proper voltage to it,
this would be a start to troubleshooting your problem.

My problem is the pot pcb that is very poorly attached to the pot so the slightest move of the wires offsets the stick center and my plane/quad starts turning.
I hot glued the pcb to the pot to try to immobilize it and it works great. The only problem is the cold weather that affects the glue and my problem returns.

All of these gimbals are of bad quality. Stick centering is another issue. There is always 0.5-2.0 +/- offset. This is very noticeable in flight, especially on the quad. I have to fight it to make it go straight...

You would probably have better luck with epoxy that should hold on in low temperatures.

Try programing a Center Dead-Spot area for the rudder control stick.
This may fix the Stick Centering issue.

If there was a mod to be able to use the replacement 9XR (Sky) mainboard in the our older 9x Radios,
this would be a big upgrade and a lot of us would want to do it.

HobbyKing has for under $10 the replacement 9XR (Sky) mainboard: (http://www.hobbyking.com/hobbyking/stor ... itter.html).

The programing buttons need to be changed some how,...... with many other thing.
There would be some difficult things to over come to get it to work.
Then the Taranis Gimbals could be used with the 9XR (Sky) Radio using the older 9x Radio case and hardware.

Then again if the old Sky9x Board Rev3 (http://www.ersky9x.net/) was available for, ...... say about $20, a lot of us would want it.

Please don't confuse the 9XR mainboard with the (Sky)board. HK sells the 9xR mainboard with an atmega128 processor, not the skyboard. It would be nice though.. ;)

9XR PRO - better gimbals

Post by Daedalus66 » Tue Dec 09, 2014 2:54 pm

Yes, the one they sell is a replacement for the 9XR board, not 9XR Pro. The early 9XR had an ATmega64, so this one with a 128 is a cheap and easy upgrade for those of us who bought the 9XR before about spring 2013.

We have asked, to no avail, for the 9XR Pro board (Sky in different format) to be made available as a spare, but using it to upgrade either a 9XR or or a 9x looks like a fairly tough proposition.

I have been using a 9XR Pro pretty steadily for a year (it's a preproduction version). I did have to replace one of the original sticks at the very beginning, as it had a gross centering error, but since then the sticks have been OK and I don't see any degradation in accuracy. My applications are not particularly demanding, I must admit.

One concern I do have is that with the coming of cold weather, the lubricant in the sticks is getting viscose and they are a bit slow to return to neutral. So I'm back to my good old JR9303 for winter flying. I'm going to experiment with Triflow lube in an old stick assembly.

Hi, guys!

It's been over 2 years since I started this topic so I feel like asking again:

Do we have a better choice for 9xr pro gimbals now?

Thanks!

Well, someone has got FrSky M9 (hall effect) gimbals into a 9X, see here: http://openrcforums.com/forum/viewtopic.php?f=95&t=9977.
Electrically, they are compatible with the 'PRO (3.3V supply). Whether they will fit mechanically I don't know.

I believe standard FrSky gimbals have been fitted to a 'PRO.

If taranis gimbals fit in pro (with some modding), then there is a good chance that these will, too.

I didn't know pro is 3.3V aswell, thanks for that! :)

Well guys, today I bit the bullet. I destroyed my 9xr pro and installed m9 gimbals.

I had to masacre the aluminum topplate of the gimbals with the angle grinder since it's too wide to fit in the 9xr pro case. I have cut the pins holding original gimbals and hotglued m9s in.

Biggest issue was to cut vertical trims in half and reattach them in the end. M9s are wider and they barely fit after the operation.

All is good now, gimbals are perfect. They center perfectly.

12 hours of frustrating work done and now I can enjoy my new gimbals.Image
