If you are just looking to practice flying to sharpen your drone skills there is a drone simulator that works really well and is very good to use for practice. It is not based on a DJI Phantom and is more like a standard non-GPS type drone. You can fly in attitude mode which gives you self-leveling assistance or you can fly in "rate" mode, also known as "acro" mode. If you are new it can be a little frustrating starting out, but after some practice, you will start to get better and better and the skills you pick up can be transferred to real life flying. The price is $4.99 (one-time payment) and is well worth it in my opinion. (not associated with the simulator myself). It is called "FPV Freerider" and can be found with a quick google search. I'm still new and not sure if I can post a link or not.
