Does anyone know why my Transformations aren’t working? i’m using the constraints to try and rig an undercarriage, which needs to swing back and rotate to fit in the fuselage. i worked out the rotation on the local Z of the Empty i’m using, but it’s not playing that way - it doesn’t seem to move the wheels for the first 23 degrees or so and as a result the end position isn’t right. any help would be appreciated
TIA

The only delay I can see to the rotation of the wheel is because the empty starts with a Z rotation less than zero degrees and you have the constraint limited to start at zero degrees
looks like that was it ~ much obliged 
EDIT - i tried putting a Limit Rotation on that Empty, limiting Z to 0 degrees and it won’t have it. setting World space and rotating on Z works, but setting Local and rotating local Z is ignored :-/
