# Installing & Uninstalling LR1 on Smart Dovetail

{% hint style="info" %}
If using the Pro Damping Kit on the IF800, IFT recommends the Vio payload be mounted in Position 2. Please see the IF800 [Payload Mounting](/inspired-documentation/products/aircraft/if800-tomcat/if800-tomcat-overview/payload-mounting.md) section for additional details.

{% hint style="danger" %}
Ensure the aircraft and payload are turned off prior to connecting or disconnecting the LR1 from the dovetail.
{% endhint %}

## Mounting the LR1 to the Aircraft Dovetail: 

1. Align payload dovetail connector with the aircraft dovetail socket and insert the dovetail connector into the dovetail socket. When fully inserted the safety latch will click.

2. Push the quick release lever on the side of the dovetail socket towards the aft (back) of the aircraft. You will feel the tension of the quick release lever get tighter as you press the lever all the way against the dovetail mount.

3. Ensure that the LR1 payload is straight and level prior to turning on the system. (see image below).

Detaching the LR1 from the Aircraft Dovetail:

1. Unlock the red lever by pulling it towards the front of the aircraft.&#x20;

2. When the lever is in the open position, press the red safety latch on the opposite side of the dovetail mount, then pull the payload towards the front of the aircraft until it slides free.
