From HK 9XR listing: * JR Form Factor RF Modules (Orx Dsm2, Orx Open LRS 433Mhz etc).

I would preffer to start using the HK Orange DSM Rx's when I update to a 9XR, but don't want to dump all my 9X compatable Rx's or carry around 2 Transmitters (9X & 9XR).

I would love a 9XR that is compatable with both the 9X and orange Rx's. Is this likely to be posible with any of the "Form factor modules" listed above. Or will the only way to achieve this be a hardware Mod installing two Tx modules (like the 9X mods)?

What is ORX Open" ????

a little hard to explain but if you go to the 2nd page on the 9xr menu screen you will find the function there.
Here I copied & pasted it from the manual

12. Trim Sw: Neat little function this is. When in flight if this key is activated it reads the current position of the sticks and trims and copies that into the subtrims. After that it zeros the trims.
This is really neat for new models when you might have a hard time taking your hands off the stick and pressing the trims. Simply hold the plane level with the sticks and press the selected trim switch. The plane is trimmed.

- go to menu, "setup"
- set "Trim Sw" to an unused switch (for example, "TRN" for trainer switch
- get your plane in the air, and trim out using trim switches
- Pull TRN switch

two things will happen:
- the trims you have set will be copied to subtrim values on the LIMITS menu.
- trims will be set to zero

It's a great er9x feature! I don't know of any other radios that have that.

In the model setup screen (from the ER9x user guide from 9xforums.com)

"9. Trim Sw: Neat little function this is. When in flight if this key is activated it reads the current position of the sticks and trims and copies that into the subtrims. After that it zeros the trims.This is really neat for new models when you might have a hard time taking your hands off the stick and pressing the trims.

Very useful on maiden flight of a not very well trimmed plane.

It's in the manual, but not obvious. It's called Trim Sw on the Model Setup menu (not a very descriptive name - auto-trim might be better).

You can choose a switch on the transmitter that will in effect convert the current position of the sticks into subtrims, while at the same time zeroing the trims. You just hold the plane level with the sticks, push the switch and release the sticks.

The risk is that you could push the switch in the middle of a maneuver and get a model trimmed for snap roll, say! So you want to select a switch that's easy to find but hard to push accidentally.

Obviously, in the video you'll see a situation where this feature would have been ideal. However, I was programming the transmitter 10 minutes before I went flying and only did the basics. I must go back and set it up.

Another programming feature that's very useful with some models, and in particular for Polaris, is different control curves for up and down elevator. Polaris has its stab set at -2 degrees relative to the wing to oppose the nose down pitch caused by the high mounted motor. It works very well upright, but when you roll or fly inverted, it takes a lot of down stick to overcome what is now a pitch down effect of the stab. If you have the usual expo on the elevator curve, it makes things worse inverted because the elevator becomes excessively sensitive just about where you want to hold it for inverted level flight.

So I set up the elevator on a curve that has normal expo (about 30%) on the up side but opposite expo initially on the down side, then a straight line the rest of the way. This means that when you roll inverted, it only takes a small amount of down to keep the nose level, but flying around inverted the elevator has normal sensitivity. This is something the alternative firmware makes easy.

Auto-trim has been around for 20 years or so but is not provided on many radios.

The Turnigy 9x comes with a module that uses the FlySky protocol. You can get such a module with the FlySky label on it and with a built in antenna. You can plug it into the 9XR and continue to use the receivers from the 9x setup. (Edit: See molond's link below)

Or you can get the Orange module that fits the 9XR (when it becomes available) and use it with DSM2 receivers such as the Orange 610.

What you can't do (easily anyway) is have both capabilities simultaneously. The 9XR has quite a bit less space for internal installation than the 9x. If you want a dual transmitter, go for the 9x, install the SmartyParts board to provide a programmer, flash it to ER9x, buy a DX4e and remove its module and install in the 9x. It would probably be cheaper, however, to have two transmitters. Or just sell your old equipment and settle on one system, DSM2.

The module in the back of the 9X is in the JR form factor but you will have to mod an antenna onto it.

You can also buy a module from FlySky that is compatible with the 9X (V2) receivers. I got mine from here:

It is a handy feature to recenter your trims at the flip of a switch. Like already mentioned...it's not a first though. I had an old Ace MicroPro8000 that worked even better. You flew the plane and held the sticks for straight and level...then pressed a button and it would slew in trim until the sticks were centered, then let go of the button. It may sound awkward, but worked great. You never had to even touch a trim switch.

Thank you very much for your answer guys. It seems very practical to be able to trim a plane with the flip of one switch while flying. I was surprised to learn this kind of radio can do this thing.

Excellent stuff ... Now you are beginning to see the true value of these $50 radios with this software! Whilst it is not a new idea, the only other current radio I know of that boasts about this feature is an $800 Jeti! With the 'trim SW' setting system, once you have it set for a particular model, land it and de-assign the switch you used to prevent inadvertant operation.
The er9x family of software is truly superb once you get your head around it and there is virtually nothing it cannot do.

Changing mode2 to mode1


For those who were wondering how to change from mode 2 to mode 1 the 9xr, here is a quick instructions from how I did it.

This is easy as far as you know how to solder (basic skills, only wires soldering).
1- Gimbals must be removed and inverted (left to right) and put up side down to correctly fit.
2- 2 wires must be cut and elongated
3- Plug on one gimbal (right only) must be removed to avoid blocking after swapping the gimbal. Direct wires soldering to do.
4- Signal and ground wires must be inverted on each gimbal wires (easy on one side of the 3 pins plugs) .
5- Radio setup must be configured to mode1.
6- Radio setup gimbal calibration must be done after changes.
7- Done!

The only little touchy part is to remove the plug on the right gimbal that will block after switching the gimbal from left to right and put it up side down.

Here are some pics for better explainations:

It's great to start seeing some mods on the 9xr.

I first soldered a JST connector onto the two spare holes of the Balance connector PCB. This should make it easier to connect a battery, and not all packs come with a very long balance lead.

Secondly I did the FrSky Telemetry mod. I used a old SP232ECP I had hanging around (a copy of the MAX232) and soldered it onto a bit of veroboard with a couple of caps - old skool style. The UART wires I then soldered to the ISP connector. I had to cut the traces and relocate the two switches too.

I used a 4 way connector I had hanging around (I think came from iteadstudio) that I used to use for a old Hitec Telemetry project and drilled a hole next to the module port for it to go through. Then glued it all down along with the gimbal connectors.

Not a whole lot room near the ISP/power connector side for mods. However on the other side (right if looking from the bottom), the battery bay has a removable section that would give a large amount of room there for future mods.

The next thing I reckon will be to connect the FrSky module into the internal antenna somehow - if I can be bothered. Either that, or I'll buy a FrSky receiver antenna extension cable and connect that directly to the transmitter module inside. Will be less RF loss that way than using RF connector adapters, also less connectors to fail. Probably cheaper too.

Si.

I have been reading this thread with rabid interest. I am astounded by the mods that you guys have done on the 9X and are planning for the 9XR. Are any of you able to help here:
