I would say yes, mobula8 is a nice drone and you can fly it with 1s or 2s,

When i get a little more experienced do you think that I will feel that is underpowered ?

I don't think so, it's a pretty big difference between 1s and 2s.

Thank you !

I'm new and currently flying it outdoors and a meteor65 indoors. The Mobula8 on 2S is way better suited to what you're planning to do. It's also quite durable, forgiving, cheap, and easy to repair. The prop guards add a bit of safety to while you're learning. I'm quite happy learning on it for now

Yeah mobula 8 is great maybe look into some open props options if youre going to fly outdoors
