"I don't know how fast they planes are in reality..."

I can't comment on any of the specific planes, but the answer to the above question: about 2x as fast as you think, if you've never seen one!

None of these planes is really fast, all under 40mph, I think, but it'll seem awful fast to a newbie. Most people don't realize how fast a 4' long plane doing 60mph really is!
