With 1045’s you’re looking at:
Thrust/weight ratio is about 5.4:1 which is good but battery load is unworkable, hover current is reasonable at 10A but the large props need a lot force to turn them on accelerationd / maximum thrust which increases to 220A !! making your ESC’s fry.
You’ll get about 4.6 minutes of flight time (11.3 hovering)
What you gain is the ability to carry a payload of 3.5Kg but would you want to on such an under-powered battery system
It’s time you moved up to 4S on a rig this size
I suggest you register wih eCalc, it’s not expensive and it’s very useful
