Any tips for flying indoors?

well i did it! but with the vision plus and not the inspire...and it flew perfect! trying not to sound big headed here, but I'm a RCHeli pilot and have flown at a comps, so flying a drone is easy compared to Heli's. i was more worried the drone would act strange, but it didn't. so i got the shoot done for a designer doing a promo for the London Ballet Orchestra.
thank you for all your help.
