But what if I don't have a 730 kV motor???

We have seen so far that for the HobbyZone Super Cub (our example plane), a great all around motor that will let us fly it very nicely has the following characteristics.

1) It will have a constant current rating of around 12.2 amps.
2) It will have a kV of about 730 kV.

But let's face it, we might not have this exact motor in our collection of motors, and we might not be able to find it at the store either. So what do we do? We try to find something as close to it as possible. So let's see what we have in our box of motors we might be able to use.

Now, I just happen to have a motor with a constant current rating of around 14 amps, and it's kV value is 890, which isn't too far from the 730 kV that WebOCalc recommends, so let's plug my motor into WebOCalc and see what we can do with it.
