Default What is KV

Hey Everyone:

I have started building foam airplanes for the last 2 months and getting help from my old boss, but since he laid me off. I lost my bosses help for the airplanes I am building. Okay, here is my questions

1. What is KV?
2. How do I determine the size of KV for the plane I am building?
3. Does KV determine the size of a Prop....

Thanks in advance.....

1. kV is the revs a motor will do per volt. So a 2000kV motor running on 7.4v will spin at 2000 x 7.4 = 14,800rpm.

2. You would be better off asking in the plane section, not the on road cars
