An experiment to use a piston to move the whole gear whilst all hinges are floppy, surprisingly, the piston managed to do its job which retracts it and extends it and it doesn't break and it shows a somewhat "realistic" retraction and extension of the gear. Although it fails to hide the whole gear and it exposes itself, some adjustments to the angle of the piston and hinges may have to done to successfully hide the nose gear and to the suspension to avoid it jumping up and down. If you want to use this feel free to slap it on to any of your aircraft, I just saw an image that is similar to what you are looking now and decided to try to make it in SP. Apologies for the disgustingly green color of the wheels by the way lol.
