Just wanted to input a little 1st hand experience, I got my LOS down pat, just started flying FPV and wanted to share my experience. I tried right out of the gate
using my F210
Racer with FatShark Dominator V3 Glasses (mistake), the depth of field and the field of view (140 degrees) was very confusing and disorienting compared to real location and situation.
I installed a HDMI output module to my Phantom 3
Pro which allowed me to use FPV with the Phantom, for those who have never used a Phantom I don't consider it flying, more like driving them, they are so self sufficient and correct many mistakes you may make.
It was much easier to get used to the FPV using the Phantom (any self leveling drone with RTH will work fine or a mini you can't hurt or hurt something else) as compared to the F210, good idea to have a spotter when first trying FPV, after 5-6 minutes of flying and pulling of the glasses you may have no idea where your drone is unless you remember your landmarks or stay real close to your flying position.
All in all, will continue using the P3P until comfortable with FPV then move on to the F210
