In the top of my nose I have a bigger door than the plans call for. This will make it easier for me to do visual inspections of the brake fluid reservoirs, allows me to install and remove the nose gear cover (it's pretty big), and will give me access to two small storage compartments I built into the nose to the left and right of the nose gear support box. I'll use these for storage of some items, perhaps a spare inner tube and/or tools, or extra ballast if necessary.
The door itself is held in place with two quarter-turn fasteners and the canard cover. The small door in the nose for access to the ballast compartment is held in place with four quarter-turn fasteners.
