The only other forum i attend is a drone forum where i spend all day answering beginners questions. Ask me anything.
But beware, i am heavily biased simply because i want more people in the hobby. Before the rest i will at least warn that this is best entered with an understanding that you're going to have to fix things occasionally. How often depends on what you buy and the nature of it. For example, my most recent flight one of a propellers blades, with no damage, flew off mid air. Since i have 3 blades per prop i was able to land safely, but a failure like that one a camera platform means the ground and fast. I do fly racers though so my failure rate is drastically higher than a camera platform. Anyway on to the questions at hand.
DJI is the big name right now. I used to own a phantom 3. The pro's, fairly easy to fly since it essentially flies itself. Your commands to it are more like asking it kindly to do things. The most recent model won't even do things you ask it to do if it can tell that they're dangerous. It does have some decent fail safe features to get it back safely in the event of a loss of communication too. The range is very good for a pre-built mostly due to their own proprietary tech of using a digital communication instead of analog which almost everything else uses. A mile over water at a decent altitude should be no problem. You'll see videos of people getting much more though.
The cons. The biggest one, whenever i flew i felt scared because if it crashed for any reason it's not designed to be easily repaired by the user, and what parts you can get are very expensive. More than they should be really.
First thing to break in a bottom down crash.https://store.dji.com/product/phantom-4-gimbal-camera
This is mostly a con for me due to my lack of easy mail access because as long as you didn't cause the problem they will usually fix it under warranty. If you don't want to potentially have weeks or months of downtime during that process though then it can be something to consider.
They're also vulnerable to disruptions which can be unpredictable. For example they use a magnometer to tell their direction and orientation, in combination with a gps to self pilot. Extreme magnetic disturbances can cause very unusual behavior, this is most frequently seen around power lines. https://www.youtube.com/watch?v=1TQ9pTSRVFE
During a cosmological event some years ago, i remember grounding myself when seeing the forecast of possible disturbances then afterwards seeing an abnormal amount of complaints of flyaways and crashes. Your mileage may vary on random events.
Also in the event that something goes very wrong with the gps unit for any reason, you could be dealing with a full blown fly away situation, where the drone takes off full speed because it's position is reading wrong. If it's responding and you can get it into a less automated flight mode you may be able to recover from these types of situations.
That said as a starter i recommend at least getting familiar with how to fly without gps based auto pilot. Doesn't have to be full manual without auto-leveling flight but something is better than nothing. A cheap durable dromida ominus or the like should work fine, but they have a limited motor lifespan since they're brushed. If you want something brushless i can recommend a few but they're designed for serious power and not necessarily a great starting tool line of sight being so small.https://www.walmart.com/ip/Dromida-Ominus-UAV-Quadcopter-RTF-Drone-Yellow/45734658?wmlspartner=wlpa&selectedSellerId=4115&adid=22222222227033059435&wl0=&wl1=g&wl2=c&wl3=69709040936&wl4=aud-310687322522:pla-116895212696&wl5=9017898&wl6=&wl7=&wl8=&wl9=pla&wl10=115794308&wl11=online&wl12=45734658&wl13=&veh=sem
Unfortunately there's no way around the, "you get what you pay for" as far as drone quality and likelyhood of failure goes. Also control with a camera view, or fpv, tends to add some cost on it's own. The cheaper version of that is cell phone wifi based drones, very short range, but cheaper. For example.https://www.hubsanus.com/shop/h501a.html
A couple other popular companies you can window shop. Hubsan, cheerson, 3DR, Blade, Xiaomi. I can only attest to the quality of dji and blade as far as camera platforms go, i consider both very good. All of those names are commonly discussed on the forums. I left out all of the overpriced under featured tiny brands i see popping up in brick and mortar stores. I wouldn't recommend any of the newcommers just trying to quickly cash in on the trend, they will commonly last a few hours.
If you want to balls deep into the information side of the hobby head here and start reading/posting. You'll see me there under MoldyStain.https://www.rcgroups.com/aircraft-elect ... rones-790/
