Matthew Christenson commented on Jonathan Price's blog post HobbyKing Selling ArduPilot Parts"The solution is simple easy here: 3DR will lower their prices in response to increased competition, due to demand.

Do you have a 'maker' friend with a small CNC mill? I worked out the Gcode for the legs on my project.

Andrew Fernie replied to Matthew Christenson's discussion Need replacement legs for 3DR Quad."Here are the spacers, and here are the screws.

I have found a product on their website to order the replacement legs, but I have not found a product that includes the nylon spacers and screws that hold the legs…See More
