I can not speak numbers but i have 4 grandchildren ages 6-12 flying c/l and learning the beginner pattern.myself have come back after a 15 year run with r/c.because i donot have to drive 40 miles to fly!My c/l models use 1-5 functions not just elevator.It is very challenging and fun and i have a lot of interest from the public especialy young one's.I do not mean to take anything away from r/c just wanted to give my 2 cents!!!!!!!
