# Light Sensor Mounting Hardware Installation

## Mast Type

There are currently two different light sensor mast types for Astro. The red mast is the newest model and is designed to work with all Astro models. 

The black mast is an older design and was designed to work with Astro models without the newest high efficiency propellers. 

Please select the mast typer that was provided with your sensor for instructions on how to install it.
