Just so you are aware I think you are comparing apples to oranges. The Champ is not reallyin the same category as the Super Cub. The Champ is tiny and can be flown inyour backyard andit's not reallya threat to damageanything or seriously hurt anyone aside from a prop strike, and even then not sure it would actually break the skin.Itmight scratch the paint if it hits a car.On the other hand, the Super Cub can be hand launched but it needs a muchlarger area to fly and a landing strip. Impacts could be significant, from broken windows to seriously hurtpersons if flown in a populated area. It's a park flyer, not a back yard flyer. Just want to make sure you understand that.
