    Hello everyone, just signed up, been following the forum for ages. So hi everyone.

    I have had loads of teething troubles with this rig, and i am going through each issue one by one.

    The help i need first, is how to re-calibrate the motor arms. On motor 3 (yaw) it is off-set by about 25mm, and limits the yaw travel on the right side. I have tried SMC3, but it doesn't actually do anything.

    The rig is the new H3R, which is supposed to be smooth for flight (which mine isnt).

    Thank you.

    Have you contacted DOFreality for support?

    While you say SMC3 does not do anything what does it actually show, can you please post a picture.

    Hello Noorbeast,

    Turns out, i have sorted the yaw axis, by relocating a mounting hole on the motor arm.

    But here is my next issue. In MSFS2020 and DCS my pitch and roll is very jittery/stuttery with minor pitch angles. Bearing in mind i have the new H3R which was advertised as smooth for flight. For whatever reason, the shafts stutter at low rpm. Here is a sine wave test picture, but trouble is, the motors are ok at the sine wave speed. Trying to upload a video of the shafts, but i cant seem to upload it.

    Please advise if you have contacted DOFreality, as they are primarily responsible for support of the rig you purchased.
