It was a robot model type thing, one of them Japanese ones like battle of thr planets, but in model form rather than animated, There was anoher one like it where this group of lads goes out to fight off some aliens and their ship was like an x and it was titchy compared to their foes and they couldnfo out and become a robot as well that had 3 parts that joined up.

I can't remember what that's called either
