The Cosmic flyer probably flys maybe 10 miles/hour and weighs 21 oz. A tower trainer proably flys around 70 miles/hour and weighs 5.75 lbs. If that doesn't make you nervous reading this, it should!! Find out from you nearest hobby shop where the near by RC clubs are and go visit them. It will be more fun and save you a lot of frustration. I found a pic of the Cosmic flyer in case any one else was wondering what the plane looks like.[8D]
