You know, it probably is a 4*120 now that I think about it. My mistake. It felt a bit off when I was typing the post, but I knew it's was 4* running a small First Place gas engine. Anyway, more power is better, but his combo is wicked silly. I settle for 2:1 thrust to weight, I think he has like a zillion to one. Gives new meaning to climb out of hover, the thing just takes off like a rocket. Cheers.
