    Hi Doctor ADHD aka @Kevinski aqnd fellow members

    Hoping you are well mate ! Your videos are awesome and inspiring.

    I have been watching your videos repeatedly so that I can start building the 4DOF Motion Platform for flight Sim shortly.

    I have already worked out the budget and sources to buy ALL tools and materials from scratch - at an expected spend of $3500 Aussie Dollars ( maybe less as there is a little fudge factor in my figures )

    I have a concern that maybe you can help me with - the concern I have is that for Flying Sims like MSFS2020, there are opportunities to fly a flight plan that can have a very slow rotation of the aircraft in a banking manoeuvre ( roll slightly to left or right for extended periods ) . Could you comment if you tried to do this super slow manoeuvre in your motion Simulator? have you noticed if the manoeuvre was smooth or did you notice any stepping or jerking ? Because the Motors will be working very slowly, can they generate enough field strength to produce enough torque for smooth operation? DOF Reality had this problem which is only apparent on flight Sim ( not driving Sim ) and the only workable fix was to redesign a new Motor+Gearbox+SFU combination as their older motors could not generate enough field strength at very slow speeds and didn't produce enough torque for smooth transition during this type of manoeuvre.

    See this video as reference

    Regarding another issue, I will be utilising a Pimax 8KX VR Headset with 2 lighthouses and am curious about the options for motion compensation... any suggestions?

    Thank you in advance for any information you can send my way
    ( apologise as not into Discord yet as I find it hard to use )
    Cheers
    George
