That's weird, was just looking at ebay and other sellers at the 3+ and it's still $399 for the most part. used $200 ish bids and best offers..... i don't see a huge change, bet most people will stick with the 3+..... I like the sharpness of this one best of all the heros but that's the result of 4k, so know i just gotta hope it can be flown jello free up at that range. Flares still suck, lens is ok, small sensor and lack of dynamic range is still it's flaw. wish you could get a back bone kit with a full size sensor and lens mount, then it'd have a chance to actually be flown for hire around me. for now i'll run it on my fpv rigs and see how it fares. Super glad it stayed the same form factor, that woulda sucked it it didn't fit all my models built for them
