# Docking a SPARK Flex

When docked with a SPARK Flex the NEO Vortex's phase and sensor connections are kept securely together. This eliminates intermediate wiring that can fail if not secured properly.

## Docking Materials

Docking the NEO Vortex with the SPARK Flex is simple and only requires the following materials and tools:

* NEO Vortex Brushless Motor
* SPARK Flex Motor Controller
* Docking Hardware
  * 4 - M3 x 25 mm Socket Head Screws (included with SPARK Flex)
* 2.5 mm Hex Key

## Docking Procedure

Follow these steps to ensure a secure and proper docking:

1. Ensure that power is disconnected from the SPARK Flex.
2. Align the motor phase bullets between the NEO Vortex and SPARK Flex.
3. Allowing the bullets to guide the two together, press the NEO Vortex and SPARK Flex together until their bodies meet. There may be a small gap between the motor and the controller opposite the bullets. This is normal.
4. Insert the included docking screws into the counterbored Docking Screw Clearance Holes on the SPARK Flex.
5. Using the 2.5 mm Hex Key, tighten the four screws evenly in a crisscross pattern until the screws are tight and secure. The screw heads should be sub-flush from the mounting face of she SPARK Flex. If you have a torque wrench, the ideal torque is 11.5 ±0.9 in-lb (1.3 ±0.1 Nm).

## Undocking Procedure

Follow these steps to undock the NEO Vortex and SPARK Flex:

1. Ensure that power is disconnected from the SPARK Flex.
2. Completely remove the four docking screws from the assembly.
3. Gently pull the NEO Vortex and SPARK Flex apart until the bullets release. Try to maintain their relative orientation to each other while pulling them apart.

## 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.revrobotics.com/brushless/neo/vortex/docking-flex.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.
