I might be biased here but drones in general, though the barrier isn't necessarily low. Learning how to fly one on a simulator is a question of 10-hours of crashing behind a screen(you gotta push through, a few hours into it, everything suddenly clicks). Learning how to build one, which parts to use, what you should and shouldn't do (motors, flight controllers, batteries, chargers, radio protocols, video, frequencies, legal restrictions, frames, propellers, gps, beepers, protocols and a ton of other) is a science in it's own right. Same with configuring the drone you've just built. But once you figure those two out, you can have endless fun: to this day I am still finding it hard to believe how easy it is to transfer your flight time in a simulator to the real world. Personally I had spent around 100 hours flying different drones on simulator and the day I went out, it felt like I've done it thousands of times before.

Community - it's generally supportive but can be pretty useless if you wanna take a single step out of the norm - you're on your own pretty much - you get a ton of shrugs and "idk".
