I've made a plane and all of the parts needed to be welded together so it doesnt fall apart.

I have a rotating propeller using a CFrame which changes it's euler angles of the the propeller, but this causes the whole model to go ape####, flinging itself all over the place before finally vanishing into oblivion.

How can I tackle this problem?

Wellll we can't see the code, so we dunno :))

Make sure the propellers are unanchored, and only welded to the plane at a point that makes sense, then just affect their rotation based on their previous rotation (but not at the junction of the weld part and the plane)

Propeller:SetPrimaryPartCFrame(Propeller.CFrame*CFrame.Angles.new(0,1,0))

Well the code for moving the plane is pretty hefty, but the code for turning the propeller is just

while wait()
script.Parent.prop.CFrame = script.Parent.prop.CFrame * CFrame.Angles(math.rad(55), 0, 0)

while wait() do*?

Yeah if your plane isn't basing its position off the propellers, and the propellers are unanchored (and non-cancollide just to be safe) then there shouldn't be an issue

The propellers are manualwelded to the part that sets the plane's position so that they dont fall off of the plane, but cframing their rotation just sends the plane insane.

Another option could be to change the weld's cframe (either C0 or C1)

unanchor all that bizniss

Make sure the propeller and the plane have NO positional reliance with each other aside from the *immobile* welding part that joins them.

If I change the CFrame of the weld constantly, the plane is unable to move.

It's not a part that joins them, it's a manualweld instance.

Can't you just put a hinge and a bodymover on it and be done? lol

If I use a hinge the props fall off.

You just need a junction that BOTH the PROPELLER and the PLANE are attached to. One that DOESN'T MOVE.

Affecting the rotation of the propeller if it's just attached with a Weld object creates a relationship between both the plane and the weld, meaning it will always go flying if the Part1 or Part0 of the weld is set to ANYTHING on the propeller that moves.
