Please let me know if I got this right.
When choosing a motor one looks at things like the power (i.e. watts, amps and volts), the size and the Kv rating of the motor. Until today I did not realize just what the Kv rating actually means. Yes the higher the rating the faster the speed of the motor. But wait there's more the higher the Kv the less torque you have. Depending on the application of said motor a high Kv value maybe desired.
So what about in helicopters. I noticed that most heli's are being built with a "standard" 3500 Kv with a 13T/14T pinion. Then one day last week I decided to look at the Protos line. A high end heli made with plastic parts, their birds are configured with a sub 3000 Kv motor and a 16T pinion. I found this strange and could not figure out why. Until today, more torque. Which I presume is ideal for 3D flight.
please let me know if this is close.
