Awareness is key to a productive session. A kid who likes to just flop around will have fun, but never get any closer to being able to fly on their own. To have a chance at moving on to being closely supervised vs. tightly held on to, a child needs to demonstrate some level of awareness that their movements have consequences (even if he or she doesn't understand what those consequences are).
He is not 40 lbs he is about 30 lbs. or so. When we took him over to the tunnel at Perris to see when he could fly they said if he met the height restriction (a mark on the wall) that he could fly. He is a solid kid, some three year olds are pretty small/petite kids. We took him up to watch them fly in the tunnel and he said he wanted to do it and they got him in for 2 minutes. The only thing he did not like was the noise, he doesn't want to go back until he is older because of the noise. As he put it "He want's his ears to be older."
I heard that you didn't need to be a certain age to do the wind tunnel. I'd like to know where the closest one to me is.
Every wind tunnel has it's restrictions, but most will let a 3+ y/o fly providing that the noise doesn't bother them and they WANT to fly.
The closest wind tunnel to you is going to be Vertical Velocity, a small outdoor tunnel, not a bad experience for kids too. It's very powerful but small and a harness is required for first timers during flight. Still a fun experience, but not the place for major training. http://www.bodyflight.net/vertical_velocity.html
I have no idea what is normal. I have no doubt she is beautiful Seeing as I am kid-less and have no reference point except for my bad memory. Thanks for the info. now I'll be more confident when people ask if their kid is old enough or weighs enough.
