first of all, what kind of park flyer are you flying? that will makea difference. second of all, i think you will be fine. just don't get too confident too quickly. that's a big mistake. i once did that, and during a field fun fly, i was doing an inverted pass abotu 5 feet above the runway, had a brain fart and rolled over onto the other side, over the pitts. i managed to power myself out of it, but man was the field master pissed. lesson learned, pace yourself.
