BIG Patriot Go-Fast
I'm not sure there are any readily available engines to make a Patriot that size really fast. I am sure it won't be fast with a Webra 4 stroke. A YS DZ 140 on 30% or more nitro Might do it. Also a Rossi 90 RIRE with marine or DF port timing running on 25% or more is another possibility.
As a point of reference I'm planning a Jett 90 FIRE on my GP .46 size Patriot.
