I have been wanting to get into drones a bit more than i am right now for a while. In the case of drones bigger seems to be more expensive but what advantages does it have over a smaller drone, what disadvantages? I can think of a few right away:

  • bigger would have a longer battery life
  • bigger would have more thrust

but

  • smaller would cost less
  • smaller might be more nimble

What spec/ability differences do smaller and larger drones have?

  • $\begingroup$ Hi, welcome to Drones and Model Aircraft SE! Unfortunately, as your questions is currently written, responses are likely to be more opinionated and less grounded in facts than we'd like. Maybe try and tighten the scope of your question by asking about one specific thing. $\endgroup$ – ifconfig Apr 24 '20 at 4:09
  • $\begingroup$ @ifconfig ive edited it, is it better now? $\endgroup$ – Topcode Apr 24 '20 at 4:17
  • $\begingroup$ It's definitely improved, but still a little broad for what I'd like. See other questions on the home screen to get an idea for what I'm trying to say. $\endgroup$ – ifconfig Apr 24 '20 at 4:34

The first thing you should consider is what you have room for. A larger drone will normally need more space to fly and can cause more damage if crashed. I would recommend a small drone if you are just starting out or if you can only fly indoors, in which case you would want a tiny whoop.

The next thing I would think about is cost. A larger drone will be much more expensive for the drone itself, the propellers, the parts (frame, electronics, etc.), and especially batteries. While a larger drone may have slightly longer flight times, one battery for a large drone might cost 10 times as much as a battery for a small drone. So, with smaller drones, you can get more flight time per dollar of battery. (you can buy 4-6 small batteries for the price of one large battery and get a lot more flight time for the same amount of money). So, if you're on a budget, I definitely recommend a small drone. It's also worth mentioning that larger drones usually use batteries with more cells so they can be more dangerous if they catch on fire or puff up.

Next, there is flight performance. Generally, it is true that a smaller drone is more nimble than a large drone, although Larger drones are usually capable of much higher top-speeds. I must say though, after having lots of experience with different drones I much prefer the performance of a large, powerful drone to a small drone because small drones often suffer from lots of battery sag due to the lower battery voltages and so they cannot sustain high throttle as well. Also, a larger drone can carry a GoPro or other camera with ease.

So in the end:

  • Get a small drone if: you only have a small area, you only have a little bit of money, you are very worried about damaging something, you want a lot of flight time for less money, or if you just don't want a big drone.
  • Get a larger drone if: You have enough space and money, you want high performance/top speed, you want something that can lift a GoPro/camera/payload, or if you just want a larger drone.

    $\begingroup$ These days small drones can provide some amazing performance. Check out the new lightweight 2.5" and 3" toothpick class. 65mm tinywhoops have also taken massive leaps forward in the last year with the introduction of good 0802 brushless motors. In my opinion, everybody should start out with a toothpick and a whoop. They are cheap, light weight, and almost indestructible making them great to learn on. Step up to something larger afterwards and you'll much better prepared to handle it. $\endgroup$ – ipaq3115 Apr 27 '20 at 23:09
