I have Mac and I phone, but I just bought an FPV and would like to use a simulator. I’ve read it needs to be a PC. I’ll need to buy one. What specs am I looking for in this PC to run flight simulation?  Thank you in advance.

Hello there makika. Good day and thank you for reaching out. You may refer to these information on installing the  DJI Flight Simulator. Just remember some tips before installing.
1. System requirements for the DJI Flight Simulator ( https://www.dji.com/simulator?site=brandsite&from=nav ) :
2. Minimum System requirements: Processor: G4560; Graphics: GTX 1050 Ti; Memory: 16GB RAM; HDD: 80GB Free
3. Recommended System requirements: Processor: i5-6400; Graphics: GTX 1060 or GTX 1070; Memory: 16GB RAM; HDD: SSD+80GB Free
4. Optimal System requirements: Processor: i7-7700; Graphics: GTX 1080 Ti; Memory: 32GB RAM; HDD: SSD+80GB Free
In addition, as of the moment I am sorry to say that the said DJI FPV is not compatible with the DJI Flight Simulator ( https://www.dji.com/simulator?site=brandsite&from=nav ) . The DJI Flight Simulator supports the DJI remote controllers for the DJI Mavic Air, DJI Phantom 4, DJI Phantom 4 Advanced, DJI Phantom 4 Pro, DJI Phantom 4 Pro V2.0, Matrice 100, Matrice 600, Matrice 600 Pro, DJI Inspire 1 Series, DJI Smart Controller, and Lightbridge 2. You may try the DJI Virtual Flight ( https://www.dji.com/downloads/djiapp/dji-virtual-flight ) using an iOS mobile device ( iOS 11.0 or above ). Thank you.
