Very cool Dale!
My 12 year old Daughter likes to look at my kits/builds, but that's as far as it goes
Now my 5 year old Son, that's a different story...he's lickin' his chops to get building. I've done two snap kits with him, but his attention span is still a bit too short. All he wants to do now is mount the tires on the wheels and get it rolling, completed or not!
Good luck with your kids builds, and make sure you post 'em up here on the forum!
