I have just finished working on a mock-up landing gear deployment mechanism, keeping it as simple as possible of course.

However one thing that I cannot seem to get rid of, is the small linear actuator's built-in overload protector from clicking.

I have tried to add a white clutch gear meshed to an 8 tooth gear in either 3:1 or 1:3 ratios but it still clicks.

If I use a 3:1 ratio the clicking and vibrations are obviously much more rapid than otherwise.

To save space, I insisted on having a fixed, almost parallel LA rather than the typical design where the LA is also pivoting like a lift-arm.

The wheels must be retracted by 90 degrees (you'll see this if you build it/watch the video)

Does anyone have any ideas on how to eliminate this whilst keeping it simple? I tried replacing the 2 x 4 bent lift-arms with a what equates to 1.5 length lift-arms so that the LA does not fully retract and start clicking but then it does not do a full 90 degrees of movement and starts bending parts if I force it.

Here is an .LXF file and below is a video showing what I mean:


I'll be able to shorten or remove some beams soon to make it less clunky.
