Hi - if I start with a brand new model.ini that I bind to DMS2, I can then build a model that seems to work OK.

My problem is that I have a lot of quite complex 4 channel mixes that use FrSKY receivers and I need to start replacing these FrSKY receivers with another receiver. I was hoping that this 4100E DSM2 receiver (or any other DSM2 receiver) would just let me take my existing model mixes and swap the channels so they worked with the different order of channels in DSM2, that is:

FrSKY channel 1 (Aileron) swapped to DSM2 channel 2 (Aileron), FrSKY channel 2 (Elevator) to DSM2 channel 3 (Elevator).

I haven't found a way of doing this even with simple mixes that just use Elevator and Aileron mixed to Rudder (one aileron servo connected to the aileron channel and one aileron servo connected to the rudder channel). As for my model mixes that contain virtual mixes and flight modes using FMODE or HOLD, trying to swap the channels seems to give the Devo 7E a total nervous breakdown.

I have looked at the old model.ini (bound to FrSKY) and compared it with the newly created model.ini (made using the Devo 7E gui, then bound to DSM2) and all that seems to have happened is that the channel order has been swapped between the two. So, it's a real mystery.

If I take the old model.ini, edit it using Notepad++ to be just like the new DSM2 model.ini, load up this new model.ini on the Devo 7E then bind to DSM2, the Devo 7E just doesn't like it.

I really don't want to have to re-program all of these model again via the Devo 7E gui, especially with all of the mistakes and time this will involve.

Any ideas?

What happens if you create a completely new model for the 4100E?

Hi - I can't get hold of my beloved FrSky micro receivers any more (they use FRSKY-V8) so bought a 4 channel 4100E RX, which uses DSM2. My Devo 7E seems to bind OK, but the DSM2 channel order is TAER, rather than the AETR channel order of FrSky.

OK I thought, so I can just change the model mixes (all simple 3 channel glider mixes with 2 aileron servos, 1 elevator servo) to use the different channel order, but this doesn't work. I've tried using the Devo 7E gui. I've tried updating the model.inis by hand. However, whatever I do, the mixes don't work, with the servos not responding or jumping over to full scale deflection one way. I've even tried setting up a new model mix from scratch and that doesn't work either. As a test, I swapped back to using the old FrSky receiver(s), rebound the Devo 7E with FRSKY-V8, and the old model.inis work just fine.

Is there something about DSM2, or the 4100E RX, working with a Devo 7E that either does not work, or works in a very peculiar way? I would have thought changing the channels around and making sure they use the correct SRCs would have worked, but nope!

All help gratefully received.

Everything unknown requires a big step forward at the beginning. The good thing is that you can try everything out on the ground without causing any damage.

In the ini file you will see that the ailerons of my kunai are mixed with a fixed value via a switch. In your case, the SRC would not be a switch, but the THR channel. Adjust the straight line of the addition as required, steeper or flatter, so that the function of the aileron is still maintained.

The use of the spoiler also triggers a fixed mix on the ELE channel. The values used are determined with the Kunai itself, but these can be adjusted.

The Kunai ini file is attached, protocol is DEVO.

Hi - I suppose my problem is that I am coming from JR 388 and a Multiplex MC24 transmitters where mix complexity is hidden behind a human-readable wrapper.

For example, on the MC24, for a 4 servo wing crow flap mix, you would first select Wing type as '4 Servo', then you would set the throws, directions and other info of each servo channel from a single menu line for each channel, with the throttle stick channel invoking the mix, and that's it! No deep complexity and no worries about how each of the surface mixes has to be built.

In contrast, deviation is a complete mystery as I can find nowhere a description of how its particular programming paradigm can be used to design and then build all of the mixes required for situations such as a 4 servo glider wing. I'm sure it must be possible... but how and where to even start?

I really like the Devo 7 transmitter as it is so small, but I guess its display and programming interface limitations are making my life difficult. Your suggestion of an emulator is useful and if you could send me your model.ini with the spoilers as an example, that would be really helpful.

Thanks a lot

I find it difficult to program such functions on a Devo 7e because of the display and the layout. I have a Devo 12s and a 7e.

Your request is really very complex and I have read various threads in another forum in which programming with OpenTX or EdgeTX was discussed. Therefore, I can get an idea of how extensive the programming can be for a glider.

If you want to program in Deviation then I would recommend that you do this on a Windows PC with an emulator, the Devo 12 emulator would be well suited for this, I think, as it offers a good overview. However, the mixers are also displayed here page by page and you have to click your way through.
deviationtx.com/downloads-new/category/2831-emulators

So you could program a basic function first, transfer it to the 7e and adapt and test it step by step.

You can have a look at the display of a complex mixer page in the manual under point 8.2.6 to see if you would get along better with it.
deviationtx.com/user-manual/user-manual-6-8-12

If you want to go this way, I can provide you with a config for a motor glider that works with spoilers as an example of programming on the Devo 12s.

Hi - I have a Devo7e and the basic programming seems quite simple. However, as soon as go to try anything complex e.g glider crow flap, my head explodes and I totally fail!

I have found the basic Devo documentation on this site, as well as DeconstructingDeviationModelIniFiles-2.pdf, but I am after something that is somewhat lower level and that ACTUALLY explains how the mixer paradigm works. For example, how would you start to think about doing something like this?:
- A glider having separate aileron and flap surfaces in each wing,
- the ailerons go up and down as standard via the aileron stick, with flap movement on each side following the appropriate aileron, but only having 20% of the aileron movement,
- the throttle stick pushed forward drops both flaps and raises both ailerons to act as air brakes (so-called crow flaps) AND also proportionally drops the elevator to hold the aircraft trim position.

I have tried to do this, but rapidly disappear into the complexities of the deviation mixers, never to return. So, how would you approach a complex mix of multiple channels, activated by different transmitter controls?

All of the documentation I have found assumes that you understand how deviation tx works, which I still obviously don't. There is some really cool model programming on this site, but even looking at this it takes me days or weeks to not be able to create anything complex.

So, any help would be gratefully received.

Hi All,

My Devo 8 has started to get vertical lines on the touch screen that make it difficult to read the menus.

Does anyone know if a replacement screen is available and if so if it is a relatively easy task to swap out?

Hi, yes I have already done that maneuver, I have enabled the module. What else can it be?

Enabling modules: www.deviationtx.com/wiki/rf_module_insta...ion/enabling_modules

Hi, I installed the nrf24l01 module and followed the guide but it gives me this error when I turn on the radio. what can I do? What module do I need to fly an each e017?

The same here. You should better ask your question in this forum thread: www.rcgroups.com/forums/showthread.php?2...tiprotocol-TX-Module

You should better ask your question in this forum thread: www.rcgroups.com/forums/showthread.php?2...tiprotocol-TX-Module

I tried this protocol but it doesn't connect, I use a Radiomaster TX12 Mark II with an IRange IRX4, but it doesn't bind with the E58, should I take something else into account?

good day everyone, hace a question: does anyone in the community know if multiprotocol exists for the ZLL SG108 pro quadcopter

Greetings, I am new to this forum and to Hobby RC and I wanted to ask you if the protocol that is used to bind to the Eachine E58 can be used to bind the E88? I have a TX12 Mark II with IRX4 module and I want to be able to connect both drones, thanks in advance for your help

I again continued to deal with my control panel on the LT8900.

Here's what I have at the moment:

1. In binding mode, the remote control has a sync word 0x038003805a5a0380, sends the following data 06 24 0b de 6a 45 05 and changes channel approximately every 918.625 µs, channels 10, 30, 50, 70
2. Based on the received data, I sent back the same data 06 24 0b de 6a 45 05 until the bullet switched from binding mode to normal mode. This usually happens from 1st to 10th reception and transmission. I can bind the remote control only on channel 10 and 70; on channels 30, 50 I was unable to bind the remote control.
3. Next, according to the SPI, the remote control changes the channel and sync word to 0x038003805a5a0B24. And starts changing channels 21, 41, 61, 120
4. I set channel 21 and sync word 0x038003805a5a0B24 in the receiver and began receiving data from the remote control.

Then I already receive the following data

06 is the data length, 6 bytes. She is always static.

1 byte is responsible for the gas trigger
2 bytes are responsible for turning the steering wheel
3 bytes change when changing the gas trigger, steering wheel and TRIM
4 bytes Gas trim
5 bytes Steering trim
6 bytes depends on 1-5 bytes and can have the value 05, 06 or 07, depending on what ranges the first 5 bytes have from 0 to 255

Now I can receive data from the remote control, but I would like to correctly set the binding and further signal processing. Could you tell me where I should look next?

Maybe start with this examples: www.deviationtx.com/forum/model-configs/...de-in-standard-mixer
