flat hard surface is actually safer for RC helicopters or planes.
grass field is not good.
if this was smooth concerete surface, the blade would probably bounced off the ground with some scratch.

Thank you for your comment.
Unfortunately, there are very few airports in Japan with good conditions, so you have to fly carefully.
