I kind of thought the same way for a long time... Then I got my first 4 stroke and have never looked back.. Perhaps a little more intitial maintanence but once broken in and running I seldom touch the settings on mine... As for power IMHO I think they are getting pretty close... The two strokes put out more rpm and the 4 strokes put out more torque... Then there is the sound of a 4 stroke... Adds a whole nother dimension to flying....
