So, I'm working on my first aircraft to post here, (may post something else in the interim, not sure yet...) and seem to be running in to a wall with regards to landing gear. I have gotten the nose gear to retract nicely, but am having trouble making a set of main gear that retract away nicely in to the aircraft. I'm attempting to make a multi-wheeled bogie for each main gear, but each time a make a test rig for a potential design there's an issue with the wheels not going in all the way or exploding when they do. Does anyone have some tips on making this work?
