HYPER .21 REPLACEMENT
 

I have a hyper 7 tq black edition with hyper .21 3port. Anyone a decent replacement engine. I saw the OS .21vzb speed tuned. But if I dont win that one on ebay. Any other suggestions. for a .21 engine that will really make this OFNA hyper 7 fly.
Here are a couple I was looking at.
