I've a decision to make, as I don't want to be without a 'copter for the rest of the season, and need to replace my drowned H soon. Looking for a definitive list of reasons why the Pro version (which I cannot seem to get yet) might be better than the "Advanced" version. Notes (to be corrected if I am wrong, or missing something) 1. Advanced has no Realsense, but could be added easily 2. Pro as a kit is more expensive than Advanced plus Realsense Module 3. Pro has longer antennae on copter body 4. Pro has three antennae on ST16 5. CGO3+ is the same on Advanced and Pro 6. Considering that RealSense Module may use power/add weight, cut into flight time 7. I cannot seem to get my hands on a Pro kit for the nominal price of $1899, as the only ones that have them are much higher .... everyone else says "Not Available - yet" So. ..when? Any thoughts? I appreciate all input. Also, I did search, but found nothing specifying these things, except in other posts, not directly related or searchable.
