Remove Text / Html Editor

Hi is there a way I could remove the text/html editor?

I have tried with no success:

add_action( ‘init’, ‘my_custom_init’ );
function my_custom_init() {
remove_post_type_support( ‘wpi_object’, ‘editor’ );
}

On the register_post_type wpi_object is declared as the post type on wpi_functions.php

also tried removing the editor on the supports with no sucesss

Thank you very much.
