    Oh great... is this true? (registration)

    Like as not that "bidding war" got started 8 months or so ago. Me thinks Reuters "discovered" this information when the players decided it was a good time for it to be released. There were upper level FAA and corporate discussions covering the current state of frequency saturation that needed...

    Battery Connectors

    You need to exercise some care when choosing Anderson's. Great connectors but you must select the correct size for the current anticipated. It's not unusual to see 15 amp connectors on systems pulling 30 or more amps. I was also curious about the OP's rating methods but feel he would...

    Just saw this on Drudge... thank you NYPD. Not.

    Can anyone feel the noose getting tighter? The first two paragraphs of the FAA PDF insinuates that all sUAS flights must be authorized. You have to get a ways down the document before things become confusing for an LEO, which at times aren't very bright.

    Just saw this on Drudge... thank you NYPD. Not.

    I hate to go all political here, but until all of us foolish people start voting for people that want to end the Patriot Act and the nanny state this kind of stuff will continue. The gov can use the word "terrorist" to concoct just about any law or restriction they want. Worse, they can deem...

    Shotover U1

    I've heard Cloudcap has been working on a really neat auto pilot system that's self learning. I hope what's in the Shotover is that one. I've got about 300 hours on an earlier piccolo system that worked pretty well. They are a company not usually in the limelight but definitely come up with...

    [Tutorial] Motor and propeller efficiency testing with a dynamometer

    Looking at your site I found the test bench to actually be pretty reasonable in price since it incorporates a load cell. Eliminating the need for a 90* arm or a straight bar on a gimbaled fulcrum and a gram scale makes for a cleaner and much reduced bench area test fixture. i might try talking...

    [Tutorial] Motor and propeller efficiency testing with a dynamometer

    I wasn't saying what you had was bad. Far from it because very few take the time to build a test stand at even basic levels. For general testing and making selections for general purposes your set up and tutorial is head and shoulders above anything else widely available. We test out VTOL use...

    [Tutorial] Motor and propeller efficiency testing with a dynamometer

    The set up these guys have is sound as far as it goes. However, measuring propeller efficiency only goes so far when dealing with static testing and theoretical calculations obtained from general reference material. We do prop designs all the time, and put them into use, and have in every...

    [Tutorial] Motor and propeller efficiency testing with a dynamometer

    So essentially a prop/ motor combination mounted on a lever arm that incorporates a transducer, right? The most important factor is always missing on a reaction dyno when measuring propeller efficiency. Blade stall that always occurs when propeller is not moving forward through the air mass.

    Oh great... is this true? (registration)

    I don't know about others but I have a tendency to gather lots of little pieces of what appear to be unrelated information and review how they might actually be distantly linked. IMO we have been getting fed a lot of media info that's providing the framework of long term planning that has a...

    Pre-release footage from GoPro Quadcopter

    You'll definitely have to up the ante from the Miss Piggy as a scantily clad girl offer:) If you're not in a hurry I'll see what I can do.

    Pre-release footage from GoPro Quadcopter

    From the time you were 16 to the age of 30 I'll bet you spent more money chasing, and keeping, girls than you ever did on RC cars, before and after:) I'm so excited about a Go Pro copter I just went out and bought a Chroma 4k...

    Let's see, big aerospace covering pipelines up north, forest fires over the U.S. and rails in the south, border patrols north and south, drug interdiction off the Pacific coast, and universities getting government grants for sUAS agricultural inspection development. Let's make it go full circle...

    Not at all. Closer to "normal":). Where would we be but for "the dream"?

    Shotover U1

    Others also learned that the hard way;). Really looking forward to the release if the Shotover. The visual aesthetics of that rig will help sales immensely if the marketing is handled correctly.

    Whimsical indeed but you have to love the Flight Test crew. Talented, creative, passionate, non conforming, not afraid to think outside the box, and willing to try new things just to see if it can work. As a P.E. you're probably aware those are all things our young engineers today fall a bit...
