The world of RC(on youtube) is almost about to reach the saturation point(reviews of different things)
I would suggest you to start some kind of tutorial series aimed at helping the newbies and your content must be excellent to attract more views.
You could also do video series about reviewing different products but they can get quite expensive and may not be that rewarding!
In my opinion you don't need a specialized camera if shooting inside your house. A mobile camera nowadays it enough for shooting good videos. And lighting is pretty important while shooting a good video. If you want a specialized camera you can go for these(my favorite picks)
1.
Nikon D51002.
Nikon D33003.
Sony DSC MK100(I think you can buy a phone with 4K capability even at a lesser price
)
For Video Editing Softwares
1. Sony Vegas Pro 11 or higher(I personally use Sony Vegas 11)
2. Adobe Premier Pro
3. iMovie(if on Mac)
And if you're doing a tutorial kind of thing the audio has to be crystal clear!
Blue Microphone Snowball iCEAnd Last, Keep videos small(max 7 mins) and crisp. If required divide it into parts!
Best of Luck!
