Hi all, I have given up struggling with Open TX for now and gone back to a Spektrum DX8 gen2 TX as I am more familliar with the Spektrum UI and at getting the Benedini encoder to work is reasonably straightforward.

So, having just got this DX8g2 working on my Panther, i have an issue that i cant seem to fix.
I set TX to Mode 2 and then set the Aircraft type to Elevon-B and this has the forward/reverse and steering on the right stick which is what i wanted.
However, Forward and Reverse with both tracks driving in same direction is on the left/right axis and the steering is on the forward/reverse axis which is not ideal.
I have tried to modify the Channel assignments but nothing has fixed it yet.
Channels setup are as follows:
1. Throttle-Throttle (Gun Elevation)
2. Aile-Left Ail (Tracks)
3. Elev-Right Ail (Tracks)
4. Rudd-Rudder (Turret Traverse)
5. Gear-Gear (Lights)
6. Aux1-Inhibit (Not used)
7. Aux2-Aux2 (Benedini Rotary Encoder)
8. Aux3-Aux3 (Hull MG Servo)

Everything else is working correctly
The wiring and Receiver in the tank was not changed so is exactly as it was when i last used it with the DX9 radio and i did not have this issue.

Any sugestions on how to fix this?

Cheers

Hi Tim

I am no expert. Far from it. So take anything I say with a pinch of salt.

On my DX8G2 I used Elevon and not Elevon B. Don't really know what's the difference between them.

Also, did you try swapping the wires going to the receiver aileron and elevator channels?

Vince

Hi Vince, my understanding is that Elevon and ElevonB are the same but Reversed - just like a servo reverse.
I have tried both in this situation but it did not fix the issue.

Not tried swapping wires yet as i assumed it was the radio setup as the RX wires are just like they were when used on my DX9.
I will try that in a sec when i stop for lunch.

OK, Swapped the Aileron & Elevator wires on the AR8000 RX but still driving tracks on the wrong stick axis.
Anyone else got a suggestion?

Tim

On this DX8 I have Elevon mixing, Normal tail. Under servo reversing, RAL is down and LAL is up.

I get the transmitter working so that:

1) Stick forwards is +100% on both channels on the monitor. Also change Travel to 150% on RAL and LAL.

2) Change the motor wires around so that stick forwards is forwards on both tracks.

3) Swap the receiver leads over if it turns in the wrong direction.

Adrian.

Thanks Adrian, Thats what i thought I had done so very confused why the up/down & left/right axis are not correct.

Will reset everything tonight and start again.

Cheers
Tim

Once again, Adrian to the rescue.
Had forgotten to set the servo reverse for Lal & Ral.
The issue is now sorted.
Thanks mate.
