Landing Legs

[Caithloki]

Hello, I am currently trying to create a landing leg but the only tutorial I can find is this one 

 

Since it is almost 3 years old it is very out of date and not relevant anymore for most of it. (I think). I was wondering if anyone can give me some help on creating a landing leg, I have the item in game but it will not animate and I do not know if I have it properly setup in unity. Any help or being pointed towards a newer tutorial will be appreciated. This is the landing leg as well, just simple up and down.

Hi have you extracted a stock landing gear and examined that?  If not I think you'll find most of your answers there, even though the transforms will be messed up the hierarchy will be pretty much correct and if legs are like landing gear, getting that right will solve most of your issues
