    @ChiChiWerx Hi! Yes, youre right. Those springs are connected via unpowered rotators both to the door and a fuselage. And a door itself connected with a powered and unpowered rotator. Unpowered one allows for some free travel - so the door first falls down fast due to pressure from those spring, but when it closes - for some time it is held by springpressure while the powered rotator "eats" the range of an unpowered - that crates a delay for the landing gear to retract before the doors. If you mean that "mesh" is a condition whether the part collides - that is set in XML properties of a part. Though i never saw them glitch regardless of scale, so dont know what you mean. May be that is because they still have collisions ON, or because they are too long and compress more than they can. I will take a look at your model this evening

    @vonhubert looking for some advice/assistance on this one. I need doors which delay closing (or close very slowly) and open quickly to get out of the landing gear's way during retraction and extension. I know you've pointed me in the direction of your M4, which I've torn apart and studied and I understand the basic concept of the suspension pushing the doors while the actuating rotators try and close them and the floppy rotators are there to absorb the initial part of the rotation. However, I still have the following questions: 1. Are the spring "pushers" connected to both the fuselage and the doors? Or are the springs simply pushing against the doors without being attached? If so, how did you position everything so carefully so that all the components attached to all the correct points, without connecting to one but not the other? 2. How did you delete the "mesh" (I think that's what it's called) from the rotator parts...also, the minimized rotators seem a bit glitchy, in that while I was playing with them, they would cause parts to jump upon spawning.
