this is very true and im noticing it happen more and more often these days vs the past. People today who are supposed to be "experts" and "professionals" are often far from it and usually do a much shittier job than you would expect from them. I cant think of anything in the last 5 or more years where ive hired someone to do something and been completely satisfied with the result, often times it wouldve turned out better had i done it myself. theres much truth to the adage "if you want something done right, do it yourself."
That calculation alone doesn't take into account the extra weight you are adding during the entire flight time from the two extra batteries you are now carrying. It's not linear. The more mAh you add to the stock configuration, the more extra weight you are also carrying.
Did you stay below 400 ft? Every mod aint for every pilot. When you start to loose connection, climb. Otherwise bring it home.
At 300ft high, I fly easy 5000ft (my situation is with a wood at 1000ft). Attention with Autoflight (waypoint or other, loosing contact, for this moment, your aircraft stay hovering, no RTH !!! If you try, fly DJI GO !!! How higher you fly, you will fly more distance!
