Wow, determining a persons knowledge of engines by the engine size they use. This seems like some boys locker room stuff here. Well my largest gas engine I currently own is ~5700cc That would be a Ford 351 Windsor in a 67 Mustang. So unless you guys have big blocks I guess I'm the expert? That line of thinking bothered me. I know many people who chose to stay in the 50cc class and under due to cost and storage concerns. It's like saying, "If you don't have a $3000 plane, your just a newbie."

C'mon The small engines opened gas to many people because now we don't have to buy a $1500 ARF to have a suitable airframe for a gas engine. Due to that there will be many new people and sure the vast majority will be small engine users but that does not preclude Stevie Silverspoon with his daddy's credit card from getting his 150cc Pitts Python and not having a clue.
