Legally the answer is NO if its not an AMA approved flying field such as the Elliot bowls in Mesa. Located on Elliot between Signal Butte and Ellsworth. Im not sure if Discovery is an AMA field but I do see people flying there without being hassled.
As long as you are responsible about it. Ive flown here before without trouble. But i usually will keep it away from other people. Most will approach you with questions, but some will ask you to pack it up. If that happens, oblige. I think that's the golden rule.
Check local laws......
I think it's alright
