Was reading others posts on wanting more power, and was thinking maybe it's time to upgrade the motor on my 450SE as well.

In looking around is the KV rating the same across brands, or do different ones rate differently?

I currently have the 430L 3550KV, would the 430XL 3700KV be better? And the JGF 450TH 3000KV isn't that a smaller/weaker motor? I also saw a Mega 16/15/3 motor, although I have no idea the KV or what the 16/15/3 means.

Which one will give me the most power, and be somewhat efficient.

Thanks,
Pete
