27 turns and yes.

## How many turns is a Tamiya 540?

For other motors, the Tamiya “Sport Tuned” motor (**27 turns with advanced timing**, equivalent to a 23 turn motor with neutral timing) is hard to beat on cost/performance increase, even if it they haven’t done much to earn the higher price tag.

## How many turns is a 540?

How can you tell? Put a very small prop (<5″) or a flat stick on the motor, hook it up to a battery, measure volts and rpm. Kv = rpm/Volts. A stock **27 turn** 540 is about 2300Kv (~16000rpm at 7.2V).

## What is the rpm of a 540 motor?

have the stock 540 motor and only **18,300 rpm**.

## What is a 540 size motor?

Those numbers refer to the motor diameter. 540 has **a diameter of 36mm**. 380 has a diameter ~28mm. 280 has a diameter of 24mm. The S, L or XL after the numbers refers to the motor length.

## How many turns is a 3300kv motor?

3300 is **13.5 equiv** if it were a Novak motor.

## How do you calculate Kv to RPM?

The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply **multiply the Kv value by the battery voltage**. Kv is in units of RPM/Volt. The more torque a motor needs to produce, the more current it will draw.

## How do I choose a Kv motor?

The KV value can be determined by **the number of copper wire windings on the stator**. Generally the higher number of winds decreases the KV of the motor, while lower number of winds increases the KV. The magnetic strength of the magnets can also affect the KV value, stronger magnets will increase KV.

## What is a 12 turn motor?

a twelve turn motor will have **more RPM, less torque, and draw more current**. The number or turns refers toi the number of times the wire is warpped around your armature in the motor.

## What does 540 mean on a RC motor?

540/550 describes **the size of the motor can**. Larger numbers mean bigger can diameter. Turns and kv are related, in that the lower turn motors are higher kv. Less turns means higher rpm, with less torque.

## How long is a 550 RC motor?

say a 540 is 2″ long a 550 would be like **2.75″ long**.
