Turnigy 9XR General

[dvogonen]

I have no information about the voltage regulator, but the radio sure works with 2-cell LiPos. It is actually the only thing I have used this far. I have flown a couple of hours in temperatures below - 10 C and there have been no power issues, only buttons that keep sticking in the cold. But that is another subject.

[dvogonen]

I have prepared a short video that describes why the Menu and Exit buttons stick in low temperatures.
One solution is to remove the glass that covers the LCD and manipulate it. The glass is however held in by double sided tape and I worry about destroying the glass in the process.
I therefore describe an alternative solution that only requires a screwdriver, a file and some patience.

The video is found here:

good video and a quality fix for the issue. Plus I like hearing the voice of the people I see on here all the time

[ShowMaster]

I agree, berry good video and modification. I meant "very, not berry"
Darn iPod spell correct.

yes, reminds me of the "recent" cooking program hype ... Twenty minutes @ -...

[kaos]

Sorry, Can't help. My fix with that is 'DON'T FLY AT -20 DEGREE C'

I am a tropical person. My cells freeze up at 37 F, let alone fly. I don't even want to go out when it is below 40 F.
My fingers will freeze up before that button freeze up.

enough fun. that is a good fix.

[dvogonen]

I would like to be able to apply that fix, but this is sadly the view from my office:

And it looks like that far to many days of the year not to fly in the white stuff. On a positive note the snow has a nice buffering effect when you land vertically (a frequent occurrence for me).

This is one of the reasons that makes me homesick

[dvogonen]

Yet another quality issue has been noted with the 9XR. At least three users on RCGroups (one of them being me) reports that the throttle stick registers slightly more extreme values in the corners than in the middle. In practice this makes the throttle idle alarm always go off when the radio is turned on, even if the throttle is turned off

I have registered a request against open9x to make the alarm slightly less sensitive.

Aww. That explains why my throttle alarm was always triggering despite being calibrated. I just turned off the alarm.

Hy,

I have only pictures from the top and the bottom side of the PCB of the TH9XR but no 9XR for myself

But I think there are the Pins 41,42,43 of the AT64 at the top-side via Vias at the bottum side connected to U6 Pin 9,10,11

So it could be more simple for Mod the Telemetry for Frsky, use the Vias to solder

load and zoom both picture, look at my red rectangels and compare yourself

Could anyone test this?

hope i am not wrong

does anyone have pictures around U6 top and bottom-side of the PCB

Hey, an office view thread... :

A bit more on topic @ Helle: that is what I meant when seeing the new board for the first time, it looks as if the telemetry mod could be easier if it works that way.... Unfortunately my radio has not arrived yet either, so I am of no help at this time...

You are right!
U6 is MUX/DEMUX 1to 8, these pins 41,42,43 are used as A,B,C addresses , X from mux is going to connect to BAT measuring analog input, where Vbat voltage is already connected to one of mux inputs, but R73/R27 is not set to do so. So U6 is useless as is. It can be used to do telemetry mod differently, or to add two more analog/digital inputs easily, because two pins are routed to connectors on the sides of the board. All of this require firmware support

[Romolo]

The pins used for multiplexer control are those reported in the photo.
Pin 43 is free (can be used for haptic in the old way)

The numbers in yellow are 14051 pins so A B C
I'm preparing the MB with a Atmega 128

Thinking about telemetry mod, probably the better way will be a new telemetrez board.

[ShowMaster]

Romolo,
I was afraid to flip the LCD flat cable lever on the mb connector. How do you unlock it? It looks different then the 9x boards?

You need to flip it up, lifting it.

Yes is different from 9x one

[ShowMaster]

Great picture, I thought that was the way but thought I'd wait for a brave person to go first!
Thank you do much.

About the telemetry mod. It looks easier to cut the trace at the multiplexer pins and tack solder there then at the m64 pins. Any thoughts?

For telemetry: a possibility is to remap AIL and THR switches on the multiplexer and read them analogically

Not a bad idea. Can Atmega chip have puul-up resistor switched on also on the analog-mode input pin?

[Romolo]

no... but pulling up two switches is easy, and furthermore we can substitute them with three pos switches...

[Promix]

Have to say I resold my 9XR !! I was too disappointed about the quality at all
- Bad gimbals feeling, impossible to calibrate endpoints satisfy like old 9x
- Buttons are an imposition !
- No module antenna protection support
- Plastic looks cheesy
and much more.

Only good thing - display is covered with real glass !

Well, it`s cheap but still not worth the money

Will buy another good old trusty rusty TH9X

[pmullen503]

How much room is there inside the case for mods? Is there room for a Frsky DHT and what you would need for the telemetry mod?

[jhsa]

Promix, you could also wait for the frsky radios.. the X9D might come out soon..

I'm more interested on the X12D.. I'm starting to save 1€ a day.. when it comes out I will have most of the money
Yeah I know, that means I think it will take long till it comes out but the x9D has to come out first so, I think the X12D will be available quite late this year..

I think it will improve... We are all beta testing it for them!

i know this old post but was reading through and saw this . i live in florida have my whole 38 years of existence. we have been talking about moving to north carolina in the higher elevations would love to wake to this in the winters

[gruvin]

My 9XR arrived today. Opened her up, had a look and then logged on here to find images from others, already done so.

Suffice to say, the G9X boards will not fit this radio.

First impressions of the radio were, "Nice." The LCD seems good. More clear than the previous models in artificial light and still very clear out in sunlight.

The only two issues I have with the radio is the departure from the body shape around the Throttle Hold and Trainer switches, where there is now a big lump of plastic getting in the way of your hands, making those switches even more difficult to access than previously. The other is the soft, squishy, semi-non-responsive push button switches.

Otherwise, all the extra stuff and general look and feel seems good to me. Oh and, the switches and pots are smoother, seemingly higher quality than previously.

The price is higher of course and I've not even tried to find a suitable connector to make use of the internal antenna, let alone actually installed a module and tested the radio "on air". But I'm sure it works.

Over all, I don't think the ergonomics of this radio warrants the development of an upgrade board for it. She sure is pretty, but a little too awkward in practical use, due to the departure from the long tested rear body shape of most all other radios. Pity.

There have been a lot of talk about the possibility to switch between stick mode 1 and 2. It has been claimed that this requires cutting wires and resoldering them. This is however not the case. Neither do you need to strip down the gimbal assemblies completely and rebuild them.
A had a look at the gimbals and made a video that describes in detail the easiest way how to change between stick mode 1 and 2.
It is a bit more complicated than on a 9x, but certainly doable for almost anyone:

Right...

Today I have done the micro switch mod that Brent came up with.

This essentially involves soldering some micro pcb push switches to the 9XR main board. Took longer to take the tx apart than to actually do the mod!!

I have only done the menu, exit and navigation buttons - was not bothered to take the rest apart for the trim buttons.

General feeling.

This is 100% essential. HK MUST do this as standard.

Suddenly the TX becomes usable. Quite how they let it out without this basic function working.. I dont know.

But all is now wonderful

[bertrand35]

Good to know. I still wait for mine again blocked somewhere in a post office. A link for the push buttons to buy?
