Is there a way to estimate battery discharge duration from mAh and C-rating?

The capacity and C-rating don't tell you how long the battery will last, just how quickly you could discharge it if you really wanted to do it as fast as possible. It's perhaps analogous to the top ...

What LiPo C-rating is best for a small 65mm quad?

C rating is very much a non-science. There’s no real way to compare between brands, so just go off the idea that the higher the C value, the better. If you want to do it a little more mathematically (...

quadcopter specification

I'd guess it can only do 90 minutes at it's minimum weight (5.4kg) and loading it up to 8kg would halve the flight time. Compared to a DJI Mavic, it's got about 20 times the rotor area, and 10 times ...

Is there a way to estimate battery discharge duration from mAh and C-rating?

If you know the current draw of your aircraft - which you can either calculate by adding each component’s current requirement, or measure with an ammeter - you can estimate the flight time for a given ...

Flight properties vs Energy Storage, is it a linear relationship?

Battery capacity and flight time isn't a linear relationship as a battery that is too small may not be able to supply enough current, and one that is too large may be too heavy for the motors to lift. ...

What LiPo C-rating is best for a small 65mm quad?

C ratings vary between brands, so it's hard to use it to compare batteries. While it defines the current the battery can provide, there's no standard for whether it means you can regularly fly at this ...
