This may be old news, but the ZDZ 210 is a bad boy if you are going big. See TBMs website.

For what its worth. I happen to like the ZDZ customer service. Mike Dooley helped me immensly on setting my 80super up. That was my first gasser and it turned out perfect when I took it to have it looked over and flown by the Dayton Giant Scale guys. One of them offered to buy it as he was flying the maiden. it was on the OLD H9 suky, but I lightened it quite a bit.

Now I have a used 3W 330 used and I am again thinking about the super 160. I have seen the posts. so I have to decide on 3w or zdz for it. the money is about the same overall.
