Thank you, I will try that......

Yep and it reverses the trigger operation as I said. Brake becomes forward, and accelerator is reverse/brake. When I try and do a controller calibration with the transmitter channel reversed it will only recognise throttle as the brake position, and will only continue when the brake is held for 5 seconds on the throttle setup. This is why I tried a factory reset which is supposed to clear the controller calibration but does not, and existing calibration works. I am using a dxs4s transmitter and an SR410 receiver

You must leave the throttle in the normal position on the radio when using a Spektrum radio in order for it to calibrate properly.
What I would suggest doing is selecting a new model on the radio, one that you have never used before. Then rebind the RX to that new model and then calibrate your radio and ESC. It would be a good idea also to preform a factory reset on the ESC before calibration.

A factory reset does clear out the radio calibration. On your Spektrum make sure your travels are set to 100/100 and make 100% sure your brake thumb setting is also set to 100. If you've turned it down whether on purpose or by accident it will change the brake EPA low enough to not calibrate.

Jeremy is correct, on the Spektrum leave the throttle channel to "normal."

Right, so back to my original question as we seem a little side tracked. How do I make the motor go in opposite direction when the manual says to keep the motor to esc connection A-A, B-B, C-C. It then says the radio channel must be reversed before radio calibration. Tried factory reset but it does not clear radio calibration. All LEDs light up as they should for a reset, All other motors I have had you reverse the motor windings and off you go but they are uncensored.
Everything works and is setup great on the ESC just motor direction is incorrect.

Follow Randy's suggestion. Make sure all your throttle settings are back to nominal and the recalibrate the ESC to the radio. Do not flip wires on a sensored system.

Make sure you check your trim and subtrim settings and all your end points. Trims should all be 0 and endpoints should all be 100

In the Hotwire you are able to reverse the motor on the Setup Tab. Also any motor timing you have in the motor will work against the motor. So 20° timing on the motor will become 20° negative timing. So adjusting your timing down to 0° would be ideal.

Thank you, now to buy a Hotwire programme connection. Had a sneaky suspicion that was the case.

A Hotwire is not required to reverse your motor direction but does provide an ESC option in reversing the motor. If you are able to, flipping the diffs in their respective diff cases may be able to get things going in the right direction.

Please don't use the radio reverse method to change the the motor rotation! Just one issue from this method is telling the esc to give the motor power whenever you hit the brakes. This can be extremely hard on all electronics involved.

You can reverse the rotation of the motor without the hotwire by selecting option 7 under MT (motor type) on the speed control's built in interface. However, you will be running in dual mode which might make the motor feel less powerful. The best option is to flip the diffs so the ring gears are on the opposite side that they currently are.

Thanks, the option 7 is not listed in the instructions so was not aware. Will try that then flip the diffs and see the differences, but there is a Hotwire coming my way anyway. They seem reasonably priced considering what you pay for a good Tekin combo anyway. Also they seem to offer a bit more flexibility, so seems like the way to go, especially for software updates and setup changes being saved.
Thanks to all who responded you've been most helpful👍

So just to clarify the issues with the new fw update has the bugs been corrected or not?

I don't want to update my RSX to 258 before I know all known bugs have been corrected.

I know on brushless plane motors, if you wanted the motor to spin the opposite direction, you could just reverse two of the connections on the motor... for example, if you wire up your wires a-a, b-b, and c-c and it isn't going the direction you want, you would wire it a-a, b-c, and c-b. Does that not work on these car motors?

(forgive my ignorance, I'm a plane guy)

It works if you are running a sensorless motor (or aren't using the sensor cable on a sensored one). These sensored motors are designed to spin one way more efficiently when using the sensors to control the timing, so running the motor in reverse by swapping two wires isn't an option.

Good to know. Makes sense. Thanks for the info.
