    Drone use by police. Different applications and configurations

    They could also use the DJI AG drone to disperse pepper spray on non-compliant crowd, lol, no need for a photo/video warrant there...

    What is your FPV Racing Setup?

    Yep, I have not broken mine yet, but did try real hard. Why did you go to 180?

    @Jim RC Hobbies, Welcome to the forum!!! Guys&Gals: Jim has been a friend of mine for quite a while now, he is a very talented professional Heli and Multirotor builder who loves to explore new things and ideas (I guess the word I'm looking for is tinkerer:). He's been always very helpful to me...

    What is your FPV Racing Setup?

    Nice machine, Talon Six, I also have a QAV, only the poh'men's G10 plastic version, lol. How do you like the Headplays?

    Lots on new changes coming...

    Actually, we can talk about my mission to remove the harmonic vibrations out of the S-900 frame, which includes balancing the motors/props. Great suggestion!

    Drone use by police. Different applications and configurations

    Absolutely, drones can be really helpful in that line of work. I think that in the short term we'll see more and more SAR done operations. Just like for commercial operators, the biggest barrier to this will be the regulations and civil liberty groups. I think that the role of drones in police...

    Dropgate - Inspires and Phantoms dropping out of the sky

    I did an experiment to see if I can get underneath the battery voltage drop issue with the Inspire 1, and actually got four batteries to drop. My article about it caused a bit of a stir on Facebook, the intention is not to trash DJI, but rather help fellow droners to avoid costly mistakes and...

    Transmitter Recommendation

    The DX9 is nice, I went to Futaba for the easy S-bus connection (1 Cable). I love the 14SG, also use the 8FG, which is also a 14 channel when used with S-bus. Not sure if they still offer the 8FG, but it was a heck of a deal since the number of channels and functionality was the same as 14SG...

    Newbie's Frist Videos

    Good question, there is not much integration beyond being able to control your shutter. The rest of the camera adjustments need to be done on ground, which is ok, but sure makes one miss the remote adjustment functionality of the Inspire. The still photos seem to be very similar between the GH4...

    Agreed, I think it really depends on what you're in it for. RTF machines have come so far that they became a great, mostly hassle-free tools for AP/AV. For drone racing, there are some nice RTF entry level copters, but building your own seems to be the way to go and a large part of the fun...

    Not too shabby, I'm sure all these building skills will come handy if you ever get to the FPV racing part of the hobby. I built a few machines before there were any decent AP RTF rigs available, and had a blast doing it!

    Help with DX7s set-up.

    Oh, good to know your gimbal is standalone, a direct connection to your receiver should be fine then. Manuals are over-rated:)

    Great point Luke, this can be easily overlooked. Lets see if Fred is still having this problem, hope your advice helped solve it.

    Tips on GoPro Hero 4 Use?

    Really cool. What drone are you using to capture this?

    Tips on GoPro Hero 4 Use?

    You're welcome, glad it helped. I do not use spot metering, it is inconsistent. I was really happy to get to the Inspire myself, for the excellent remote camera control options it offers. Would you mind sharing some of your work with Agisoft here?

    FAA Sued In Federal Court Over Drone Registration Rules

    I think this summer may be a bit optimistic for the 107, maybe 2018. Good news is that you'll be able to buy an Inspire3 by then:)

    Let us know what your favorite brand of radio equipment is

    I'm there with Maxx, Futaba 14SG. It's a really reliable controller, and S-bus makes it easy to connect to most flight controllers with only one wire, making for really clean installs. I've has Spectrums before, their 18 channel is nice, I still keep a 9 channel Spectrum for my bind&fly toys.

    Has anyone seen racing drones with rear and side props for more speed & agility?

    I'd say a variable arm angles may be cool-most racing quads already have tilted motors, wonder if there would be some benefit to making this tilt variable.

    Maxx4wd, that is a pretty cool collection, I also-ran my 250 with Futaba 14 SG, lol.
