    Learn to fly for the public

    Hi everyone, So I teach at a local public makerspace*, close to Boston. It's run by the local library, so it's free for all citizens to use. It's pretty cool - you can check out our Meetup page if you're interested. I teach 3D printing classes and lately I've started a project called, for lack...

    "Weathervaning" a low-drag surface for a quadcopter arm

    Hi everyone. You've probably seen these things flying around a lot lately: The "Arms" are the things that hold the motors on the end. I want to 3D print a quadcopter frame, and I would like to streamline the arms. Right now they are flat plates, so when the quad is tilted forward, they end...

    BAN ALL DRONES! - Eric Zorn, Chicago Tribune

    I haven't read this but it popped up on a Facebook group I follow (The Mini Quad Club). The replies from the group ranged from "Yep and I'm not even sure a Phantom can get to 1700 ft agl, which is where the pilot of this most recent incident claimed it was." to "we need some serious rules and...

    e-Go Aeroplanes

    e-Go aeroplanes - Welcome Not sure if you guys have seen this or not yet. They posted here a little while ago, and I actually interned for them during one summer (huge thanks, it was so much fun! :D). They've got an actual, flying experimental prototype now, and it looks gorgeous.

    New buzzwords/slogan for aviation

    This is something that's always bugged me, so I thought I'd open up the discussion. Everyone in aviation is obsessed with safety - "this aircraft is the safest!", "so safe", "safest way to travel", etc, etc. Not saying safety isn't a primary concern, but it is kind of boring. I got these off a...

    Design Inspiration - my Aerial Remotely Piloted Vehicle

    Click the images for a larger view. These don't have the sensor screen and camera blocks; I did this project to learn Fusion 360. It's user interface is cumbersome, but it's neat to work with the three different modeling materials. Once you figure out it's quirks it's reasonably...

    Hi everyone. I'm looking for a parafoil that can carry 30-40 lbs of weight in 15-30 mph winds. Does anyone know of one or have a list of parafoil manufacturers I should check first? Thanks. -IV

    Other foams that do not outgas toxic chemicals

    I am looking for something similar to the blue, yellow, or white solid foams (what are these called?) typically used in aircraft construction, but that do not outgas toxic chemicals when heated or melted, that are also easily sandable and have a low melting temperature. Does anyone have any...

    How does lift *actually* work?

    I know this is a really "duh" question to be asking on this forum, but as I've explained lift to people, I've always gotten caught up in the details. There's the Burnelli theory, the most well known one, which doesn't account for aircraft flying upside down. There's the vortex lift theory...
