This as usual has got way off the trail ,but it does make for some interesting reading .Now i'm told that a 2 stroke engine has more torque than a 4 stroke .I'm sorry but I dont buy that for a sec .If that was the case they would be able to swing as big or bigger props than the 4's can in the same size of engine and turn the same RPM's . Agreed in some cases there close but from what I have seen the 4 will still turn larger props without overloading the engine .
