Multirotor hobbyist here - are those props some sort of strange heavy lift configuration? I've never seen such a long chord length on such small props. Anyway, unless those props are somehow very special, there's no way that thing flies for 20 minutes. Way too bulky, that body is blocking like 20% of each prop's thrust, and quads that size just can't carry a 3 axis gimbal for that long.
