I have yet to watch any videos, but man are most of the BetaFPV light! alas, they also have lousy run times. are there any sub-250g models that have flight times of 10 minutes, not the 3 most of them report? a lot of the better models from BetaFPV are in the DJI Mini 2 price range after exchange and those come with 20 - 30 minutes of flight time.
My 3 inch build will run any where from 3 to over 10 minutes depending how you fly. Probably more if I swapped out the props and down graded to 3s instead of 4s. The DJI crap has better flight times because they carry much larger batteries then the comparable free style / race quads we use. They also use a lot lower kv motors to turn high pitch 2 blade props for efficiency not for speed. They are also optimized for super low rates which don't allow for maneuvers that take more power to do like flips and rolls.
Cinewhoops are designed to carry a camera AND protect the surroundings for getting close up on things. The ducts that protect from contact with the props are very inefficient and take away power as well. If you want extended flight time you are going to sacrifice the power to carry a camera switch to two blade props and match motors to low amp use so you can switch to using 18650 batteries instead of lipos.
Its the nature of the beast. You CAN design to do a specific task and be good at it. You CAN NOT however design to do ALL tasks. You CAN tune rates on EVERY quad built to make it fly docile like a tiny whoop or aggressive like a race quad no matter what the size and power. Its a matter of balancing and trading power and efficiency to get what you desire out of them.
Here is my 3 inch doing free style stuff in pretty significant winds for its size and weight. I think with the 4s 850 battery and the CP antenna and mount it was 253g with a dipole and no mount it was 248 and change. It also has a full size vtx and fpv camera not micro stuff.
and here it is with dropped rates for cruising. Keep in mind also it was in ground effect so open air cruising will have even better flight time.
