I am interested in this comparison between 13500kv 2S and 9000kv 3S. Which is faster and which do you prefer?

scirocco Feb 04, 2024

I prefere 3S version with 9000KV!
2S 13500KV is more accelerate but maximum speed is looks like same!
"numbers" can show us the acceptation... roughly 9000KV vs 13500KV -> 9000x12V vs 13500x8V -> 108000 vs 108000 -> weight? 65g vs 77g
big different is "volt drop" and fly time! 3S is more economy and can fly more than 1 minutes plus! 2-3m vs 3-4m!
first 30 sec.... 2S 3.8V vs 3S 4V... so 2S version gets volt drop very fast if force it :)
I added photo about it! Where you can compare them! "G" / "Throtle position" / "Volt" / "Time"
