Thanks everyone for all the great information but I finally decided to go with a 2-stroke. I purchased the O.S. AX1.20. From everything I have read it is an awesome powerplant. If I have any fuel delivery problems I can always add a cline regulator (they work fanstastic. I have one on my ST G90 and It runs flawlessly). I haven't had a chance to bench test the 1.20 yet but I know O.S. quality and I am sure that this will be a great performer in the U-Can-Do. Thanks again everyone for the input.
