I never ran 4 stroke before, and still like the idea of 2 stroke sound in the U CAN DO 60 . I can not see any difference between my O S 65 and a 91 4 stroke . ( I feel if I go 4 stroke it should be big)
The 3 engines I am looking at are - MAGNUM XL-91. RFS, Thunder Tiger 90, OR something like 110 or 120 4 stroke, that some day can end up in a war bird.
What should I pick.
