Hello there fateofangel. Good day and thank you for reaching out. The DJI RC Pro ( https://www.dji.com/rc-pro?site=brandsite&from=nav ) compared with the DJI Smart Controller ( https://www.dji.com/smart-contro ... ;from=insite_search ), the performance of the CPU and GPU of DJI RC Pro is increased by 4 times and 7 times respectively, with boosted system performance and lower power consumption, offering longer use duration and a smoother control experience. DJI RC Pro also features a comprehensively improved transmission system. It supports the brand-new O3+ transmission with a livestreaming at up to 1080p/60fps and a max transmission range of 15 km. In addition, DJI RC Pro supports screen brightness up to 1,000 nits while the DJI RC ( https://www.dji.com/rc?site=brandsite&from=nav ) supports screen brightness up to 700 nits. The DJI RC Pro supports third-party applications while DJI RC does not support third-party applications. Lastly the DJI RC Pro is equipped with four antennas while the DJI RC is equipped with two antennas ( the same as DJI RC-N1 ). Thank you.

Its very clear for me now

Will the RC Pro let me use 3rd party applications with the Mini 3 Pro or Mavic 3?

not really, hack only
