960Kv versus 880Kv

I just purchased (from a private sale) what I was told was a HH 480 size 960Kv motor as a direct replacement for my PZ Mustang..... but now that I have the motor in my hand, I see there is a chinese ticket on the motor that says it is a 880Kv motor (it also says 480 on this ticket).

What would this mean to my Mustangs performance if I were to install the 880Kv motor instead of the correct 960Kv motor?

Theoretically it would have about 20% less power (with the same prop etc.), but a lot depends on the particular motors.

Horizon Hobby's Parkzone 480 (PKZ4416) is supposed to be 960Kv, but my sample tested out at just 912Kv. If your replacement motor's actual Kv is little higher than marked then the difference may be negligible.

I've tested two of the parkzone 480 models advertised as 960Kv and found the actual Kv to be about 905 on both of them. I think it is safe to say their Kv is much loser to 900 than the advertised 960.

Sounds like this describes them very well!

So basically Ė if the motor didnít have this ticket on it saying 880Kv Ė I may not have noticed a difference. ......Especially if the motor Iím replacing also ran a lower Kv than advertised.

Most likely, unless they were both run up on a Watt Meter for comparison. Watt Meter is an essential tool for electrical flight. Although they may be a bit sloppy the low cost motors are still a fantastic deal. First, most of them work just fine with their little anomalies especially taking the cost per watt into consideration. Second they provide a diamond in the ruff, just takes the stone cutter to reveal the gem. Even the lowest cost motor with a good wind becomes a jewel.
