In the first flight, I did 2 landings on a school basketball court, and that was easy. This court is adjascent to the baseball field. But the school teams showed up, so I went to our RC field where I had the second flight.
The plane did a great elevator from about 30 feet down to a couple feet; I maintained that altitude in a forward harrier on about 40 feet, and was going to let it land when the left wing dipped and touched the ground.
I think that landing it smoothly as I did on the Basketball Court, with no landingear on the grass should be OK.
Knife Edge Landing not recommended !!!
