# Physical Specifications

The Kraken X44 is designed to be a drop in lower power replacement for a Kraken X60. This means the lower weight, lower power but similar rpm.

## Diameter

<table><thead><tr><th width="294.3333333333333">Description</th><th width="378">Value</th></tr></thead><tbody><tr><td>Diameter</td><td>44mm / 1.73in</td></tr><tr><td>Effective Diameter w/ Bump</td><td>47.4mm / 1.866in</td></tr></tbody></table>

{% hint style="info" %}
**What is the bump?**

The bump is where the internal motor's stator wires are routed to the back of the motor. This feature was added to allow there to be enough clearance so the wires couldn't contact the motor's rotor.

## Length

The length of the Kraken X44 depends on the version.

| Part Number | Description           | Value        |
| ----------- | --------------------- | ------------ |
| WCP-0941    | Kraken X44 + Talon FX | 75mm / 2.96" |

## Weight

The weight of the Kraken X44 depends on version.

| Part Number | Description           | Value    |
| ----------- | --------------------- | -------- |
| WCP-0941    | Kraken X44 + Talon FX | 0.75 lbs |

## Mounting Holes

Kraken X44 has (11x) #10-32 mounting holes on a 1.375" bolt circle, spaced 30 degrees apart.&#x20;

### Blind Holes

Each mounting hole is blind, meaning it doesn't go through the mounting plate. By using blind mounting holes, teams cannot lock the motor's internal rotor by using too long of a screw.&#x20;

### Pilot Boss

The Kraken X44 also has the same 3/4" diameter pilot boss that the KrakenX60/CIM/MiniCIM/NEO/Falcon has.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wcproducts.com/welcome/electronics/kraken-x44/kraken-x44-motor/overview-and-features/physical-specifications.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
