    SMC3 can do 3 motors but does not treat all 3 exactly the same way, so using an additional Arduino, given how relatively cheap they are, can be advantageous.

    once I have added the second Uno3 card I guess I just change the config file to match the new card com port. But what is the correct setting for the serial port setup in sim tools or flyptmover ?

    In SimTools you set it up as a separate controller in Interface Settings, specifying the correct port and axis designation.

    After purchasing a new IBT and the decision to use a second arduino all is now working perfectly. Many thanks for the help.
    One more question. In SimTools and flypt what do I put as the axis assignment under the serial interface settings. Is it just [C<Axis3>] on the second arduino for the 3 rd motor (traction loss)

    For SimTools it should be [C<Axis3a>]

    Thankyou . All working fine now. I did however have to change from [C<Axis3a>] to [A<Axis3a>] . As this third axis was on second arduino .

    Before I dive into properly setting up, as I’m only using for MS2020 flight sim what are the best axis assignments to use. For Yaw should I use Yaw velocity?

    Also after using the tuner in sim tools 3 both for ground and then air, how do I tone down the ground movements as it’s way to strong.? Do I use the sliders, and tone down by moving slider up and adding to the limits?

    Anyone got a successful flight sim setup in sim tools 3 I could copy and use as a good starting point.

    I use 2 h-brige parallel on one 24v motor. 1 h-brige overheat and stops. Going error like status in a short time. 2x ibt parrallel did the fix. If using big 24 high amp (250watt wheelchair motor) they are stil in my opinion fast. Need more reduced gears.

    I'm using SMC3 for my rig and I want to try pot scaling.

    Can anyone give me a recommendation on the specs for a pot that is suited for this job? I have no idea what maximum resistance value I should choose.
