Rotating welded part locally

[PureGamerGames (Pure)]

Hello, I have four propellers welded to the main frame of a drone and I want to rotate the parts. Here is a diagram of what I want to do in detail:

The first thing that I tried is CFrames. For each propeller I would run the following line:
script.Parent.CFrame = script.Parent.CFrame * CFrame.fromEulerAnglesXYZ(0,5,0)
to rotate each one.

However with the welds, as expected, the whole model ends up moving rather than each propeller on its own.

I then tried changing the weld via:
script.Parent.qCFrameWeldThingy.C0 = script.Parent.qCFrameWeldThingy.C0 * CFrame.Angles(0,math.rad(5),0)
which resulted in the main frame of the drone rotating, but not the propeller.

I am a little lost at what to do now. I see another thread suggest disabling the weld and then reenabling it after performing the CFrame rotation, which resulted in nothing moving at all.

Thank you for your help…

If you are using a weld constraint I believe you can just convert the CFrame into an orientation value you can use to change the propeller part with.

Rotate Part Relative to model not world

Hmm, Maybe the angles being returned are in radians? try doing script.Parent.Orientation = Vector3.new(math.deg(x),math.deg(y),math.deg(z)) If it doesn’t work I suggest using @Deriv3ds CFrame:ToObjectSpace() to convert the goalCFrame relative to the motor part0 of the weld Joint, then modify the weld’s C0…although I would recommend turning it into a motor6d since motor6ds are intended to move while welds are stationary (using RigEdit to connect the motor6d joint).
