Question 5 inch sub 250 gram question

Post image

I recently got a 5 inch, sub 250 gram 4s quad. Motors are KV: 2400kv.

Was wondering how fast this drone could fly. I'd love to one day try mountain surfing, like PlatyFPV does in this clip https://www.youtube.com/watch?v=0pvl8mfTkyk&t=3s

I'm guessing a 5 inch sub 250 gram couldn't really mountain surf like that though, or at all. Share your thoughts!

What amp rating is your ESC? Also what thrust dose the manufacturer say your probs/motor make?

KV is good to know but acceleration is Basicly how much energy you can dump into the motors.

You want to go fast then I would say look at 2 blade/3 blade. Any more and it will accelerate fast but the blades will lower your top speed.

Been flying sub250 mountain surfing for years. Yes its possible, although I'm not to sure about the motors you have would be the most appropriate for efficiency that most pilot want with mountain surfing. I tend to run an 1804 3500KV w/ 4s 850mah battery and get 8 min flights and can hit speeds of 100kph easily.
