As you say, you do not want money taken off the top. It seems that a lot of sites have increased their rates due to the increased use during the pandemic…
I would offer Craigslist as an option, it's easy to use, and there are no fees…
But the one issue some sellers have is the Face-to-Face meeting of the buyer and there are plenty of scary stories of sellers being robbed. Our local police station offers a trade/exchange zone in their parking lot under surveillance, which thwarts potential robbers.
If your community does not have such a place, contact the police, non-emergency phone number (NO 911 Calls…) and ask for suggestions. There might even be a community swap meet that you could meet up at (lots of people, you would not be alone)…
Your one issue is that you will need to demonstrate it and possibly let the buyer try it, if you do, be sure to set the MAX Height and Distance that your drone can fly… I do this when the Grandkids fly, then I do not have to keep so "constant" an eye on what they are doing and they cannot bother the neighbors…
In the advertisement, Also, spell out that your Drone is registered with the Federal Government (FAA). That the sale is As-Is, No Returns (you do not want them crashing the drone and then claiming it was defective…). Tell them your price is FIRM, any and all use, defects, scratches, marks, etc… have been factored into the selling price.
Take lots of Photos, many angles, include all items, Drone, Controller, Batteries, Accessories, Paperwork, Cases, etc…
Make sure the advertisement spells out: Price is $XXX.00 Cash for all. Items will not be sold separately. This Price is NOT Negotiable. I do not take Checks, Credit Cards, Bitcoin, or Payments.
To set up an account, you only need an email address. I have 7-AOL email accounts and several Gmail accounts. You can create a Gmail Email Account just for this and then you real email address does not make it out into the Internet Swamp for SPAMS, PHISHING, and Junk Emails…
Below, is a copy of a Craigslist that I am running right now…
