Yes its motor centers across the entire craft not adjacent motor centers. That means the entire thing will be a only 40mm larger diamensionally which yeilds about 6mm greater clearance between adjacent rotor props giving you a maximum larger prop of 3mm compared to the current one.
Its 7% larger 480mm vs 520mm across with a battery 21% more capacity 5400mah vs 6800 mah that yields 20% increase in flight time 25 minutes vs 31 minutes.
Then you factor in 20% fluff factor and its a real flight time of 17min given the new payload doesnt weigh more than 20% compared to ours
Which means if we put the new camera flight time will be at 14 min more or less with a factory battery.
I can already see more companies getting larger batteries for it.
Also you can always extend your factory carbon fiber arms out an extra 30mm on each arm by buying a longer carbon fiber tube and make your H480 a H540!
Very soon the prop on the right will fit your H480, anyone wanna help?
