Things to keep in mind:
-Display only "normal" LEGO engines, not entirely Technic (but go ahead and use Technic pieces)
-Can be non-functional or functional
You've probably already seen the engine on my spaceship, I went in the opposite direction this time and made an old timey engine, with copper pipes and stuff, lol. Was a little limited because we can't make illegal connections in LDD, but it looks alright. I imagine it would connect to stuff with the two robot arm things in back.
I like to make them around these sizes so the minifigs don't look terribly out of scale with them.
