What should I try to anticipate before flying indoors? (I'm thinking of flying in a convention center...large room... before people arrive) I bought a Proto X quadcopter and flew in inside. I crashed it so many times because it is never stable(when new it flys somewhat stable but after multiple crashes the motor mounts get loose. It is definitely fun easily repairable after each crash. Great for Kids). I worry the P2V will fly the same way I think I should turn off GPS and RTH but how? Do I mess with the switches?
