E370 1200KV vs 1800KV: How to Choose Your Plane Motor
E370 1200KV vs 1800KV is a choice between slower spin with larger props and faster spin with smaller props. The 1200KV motor at $11.99 suits small airplanes, and the 1800KV motor at $13.99 suits pusher-prop planes, flying wings, and racing planes. Both motors share a 2208 stator and weigh 42 g, and the 1400KV motor at $10.50 sits between them.

What does E370 1200KV vs 1800KV mean in the air?
KV states how fast the motor spins per volt with no load on the shaft.
The 1800KV motor spins 50 percent faster per volt than the 1200KV motor.
Both motors weigh 42 g, so the KV rating is the main difference between them.
Which airframe suits the 1200KV motor?
The 1200KV motor suits small airplanes, per its listing.
Its slower spin suits larger props that move more air at lower RPM.
The 2208 stator keeps the motor light at 42 g for small airframes.
Which airframe suits the 1800KV motor?
The 1800KV motor suits small pusher-prop planes, flying wings, and racing planes.
Its faster spin suits smaller props that need high RPM for speed.
It shares the same 2208 stator and 42 g weight as the 1200KV motor.
Where does the 1400KV motor fit?
The 1400KV motor at $10.50 sits between the two motors in this guide.

How do you pick an E370 KV in 4 steps?
- Note your airframe type: small airplane, park flyer, wing, or racer.
- Pick the KV band for that airframe: 1200KV, 1400KV, or 1800KV.
- Match the prop and cell count to your airframe, per the motor listing.
- Check the 42 g motor weight against your airframe balance.

Frequently asked questions
Can I swap KV ratings on the same airframe?
You can, but you must match the prop and cell count to the new KV rating and your airframe.
Does higher KV mean more thrust?
No. KV states spin speed per volt, and thrust depends on the prop, battery, and airframe together.
What cell count do these motors take?
The listings do not state a cell count, so match the prop and cell count to your airframe before you fly.
How heavy is each motor?
Each of the three motors weighs 42 g, with a 2208 stator size.
