I want to purchase a plane that is rated for a 1.20 - 1.50 4 stroke engine. I have a 1.20 but prefer to power my planes with engines at the top end of the recommended range. I can get a hold of a 2 cycle 1.08 but I don't know how this engine would compare to a 4 stroke. What 2 cycle engine would compare to the power of a 1.50 4 stroke?

Thanks,
Danny
