RE: Some questions about grass runways.
My girls love to watch Dad fly, the 11 yr old even has a couple of buddy box flights on the trainer. If I confine them that long is when I have issues LOL. I would not trade them for the world. The first time I took them to the field, the baby saw my plane and asked what it was. When I hit the throttle for the take off and it went down the runway she took off running screaming AIRPANE AIRPANE AIRPANE. Now she does it everytime she sees one anywhere. They are her favorite thing to help Dad with. She sits with mom holding the airtronics vg 400 without batteries or antenna and "fries airpanes" with Dad LOL. That is priceless.
Have a blast with them watching those warbirds.
