Hi All,

Ok maybe I missed something here, what type of boat is this engine going in? If it is a cat, I have never seen a .21 cat run in district 4 ( make sure the district you plan on racing in has the class you want to race available). If it is a mono .21 or .45 are your choices, anything in between these sizes will race with the .45's. If you are modding a RTR to race why spend the money on a cheap upgrade engine, and if you are spending money on a good engine why waste it on a RTR boat (if your going to spend $300+ on an engine, it would be a waste to put it in an RTR). Sorry if I did see what boat this is going in. As far as an STS .28 has anyone here ever tried that engine, if so I'm not really sure I have ever seen a post saying any pros or cons about it?
