Here are the over priced and sometimes hard to find nylon screws for mounting the FlyZone Sensei (and others) wings.
When I couldn't find any in stock anywhere I went straight to the manufacturer and bought 200 of them.
I can't find any metric nylon screws at Lowes or Home Depot, either, so I decided to make them available to others who might need them. I'm selling them for $1.00 each. Free shipping if you buy 5 or more. Otherwise shipping is $3.00.
