The top photo shows how to store the prop guards. It's a tight fit but you could trip some of the foam to make the slot larger. There's enough room below the lid foam so you can close the lid without any issues.
Hey Fred, thanks for posting this close up shot. I should have my 'Fly More' GPC case from them in a couple of days. Decided on the slightly bigger case so I can store my props, battery charger etc. Felt a bit more room would suit my needs. They, GPC seem to have a quality product compared to others.
