Thanks. I took another look to remind myself again of the details of the design. It has four large ion thrusters for up-thrust so I'm wondering why you're having trouble with "lift". Are you operating in space or on a moon? It doesn't matter, I guess.

I've noticed that sometimes these things don't move correctly when they're fully loaded, even though I've put a zillion gyros in them. Try wiggling the ship (i.e., mouse) a bit when going up; that will sometimes get it out of its "zombie" zone and allow flight to occur normally.

That said, however, I can relatively easily add up to 16 small hydrogen thrusters to the bottom to aid in up thrust, and a few less at the top for aiding in down thrust. What are your thoughts about doing this?

Hey, I just wanted to say I really like this miners design and the capacity, only issue I had was there is very little upwards thrust so as soon as you get a some ores and stone in there it wont go up. I kind of just slapped some hydrogen and Ion thruster's on the bottom where I could and It works for me. If you do another version def add more up thrust. :)
