    MY1025, MY1016 are approved.
    RPM on a wheel should not be less 200rpm.

    They exactly the specs you are looking for. Remember BTSim with my1016 switched from 1:4 to 1:6 ratio. said that 1:6 he liked more. I'm using the MY1025 with 1:3 and that's ok too for it. And I'd advise not to give more then nameplate rated current for them, are in terms of power. Now experimenting with 24volts and 10 amps psu for it. So even may be less current can be given, for all that heat capabilities stuff etc.

    Okay , and how about stall Current Amps , can stall Cureent exceed PSU max Amp or should i be looking at Rated Current for the motor . Im struggling with undestanding should i buy a motor with high torque but even higher amps (80 - 130) or upgrading my PSU . Then there is the Driver problem , how many amps i need to hold , parralel or only one driver.

    In the posts you mentioned , there is a part about 550 . "But can be good as is for, let's say, 550 motors. (1.4 on idle, and 10-12A of SC)." Does this mean they use 10-12 amps of Stall current at Stall , but when i check documentation it says 85A of Stall current. I ve searched far and wide for a confirmation to order the right motor for my 12v 30A PSU . So anything you can add or confirm i will grealty appreciate .

    Let's make it simple. Again.
    The PSU for Logitech G25/27. Motor kinda of you favorite RS550.
    No 85a stall current + safe amps for PSU capacity. No current limiting resistors, or whatever else etc etc.

    There are two motors in the wheel base in addition.

    If you expect mature wheel base build, don't expect it from rs550.
    1000w MY1020 for your psu should be good. People are happy with this motor for many reasons.
