In a few months I am going to start purchasing parts for a new plane, hopefully I will have all of them by late summer. I decided that I would like to go gas with this one, due to the cost of fuel. I am looking at several gassers, one is a two stoke, the other is a four. The engines are the Evolution 35GT2 (2.15) and the other is the Saito FG-36. By comparison, the 2 stroke seem better, its lighter, more powerful, and seems better priced, although their seems to be a list of things still needed. What advantages does the four stroke have? The Saito seems to come as a complete package compared to the EVO.

Thanks.
