Run Time - Heli vs Plank

[Billybuck]

I know there is a lot of RPM difference between these two motors but if somebody could just tell me what to expect for run times on a FP 4900 6S running the following motor on a plank vs the same pack with the stock 600XL on my 600.

There are probably too many variables to predict, but what the hell, thought I would ask anyway.

Heh. Everything depends on the prop, the plank, and how heavy you like to be into the power. If it's just a trainer floating around you may get 20 minutes, if it is fast and at high throttle levels, 6-10 minutes, aerobatic varies depending on how you fly.

If you are at 75% of rated continuous current (30A) you'll be drawing 6.1C (~600w)and fly for ~9.8 minutes.
