This appears to be a chance since I too recall when you were able to edit an existing drone in your inventory. I suspect they have blocked this because I used that method to renew my registration for another several years without adding anything RID and as a result, I don't have to revisit the website for many years even after RID becomes available. If you try today, you cannot renew your registration without providing the proper RID details. EDIT is a function for part 107 only. Here are the instructions for the recreational flyer which basically means you have to add new equipment and then delete the old entry.
Recreational Flyers Registration
Recreational flyers will need to add each Standard Remote ID drone and/or the Remote ID broadcast module to their inventory, then if applicable, remove the non-Standard Remote ID drone(s) that it replaces.
- Log in to FAADroneZone
- Click on the button labeled “Launch Drone Owners and Pilots Dashboard”
- Be sure you are on the Recreational Flyer Dashboard
- Click on “Manage Device Inventory”
- Click on “Add Device”
- Answer the Remote ID question “Yes”
- Choose the device type from the drop down menu (Remote ID broadcast module or Standard Remote ID drone):
- If using one broadcast module on multiple non-Standard Remote ID drones, select broadcast module for each and input the particular drone(s) make/model while using the same Remote ID serial number from the module in the following step.
- Enter the Remote ID serial number (NOTE: this number may be on either the device or the controller)
- Click on “Add Device”
- Return to “Your Inventory”
- If you’d like to cancel the previously registered non-Standard Remote ID drone
- While in your inventory, click on the three vertical dots associated with the drone under the “Actions” column and select “Cancel” from the drop down menu
- Note: a canceled device will remain in your inventory as “cancelled”
