Ok, now for what you dont see...

1. My base station: Just a cheapo camera tripod from Best Buy. But instead of a camera mounted to it, I have my video receiver antenna on it and my video receiver & SAW filter. The antenna looks like a small pizza box... pretty much just a flat square piece of plastic about 8"x 8" and 1" thick with a wire coming out, and my receiver screwed to the back of it. My video goggles plug into the receiver. For power, I have one of those medium size plastic toolboxes from Sears, the kind with wheels and a handle that pulls out. I keep some tools in it and spare propellers, but the bottom of it has a 12v marine battery that powers my goggles, the video receiver, and my battery charger for my flight batteries.

2. Battery charger: You have to get a LiPo charger in order to charge LiPo (lithium polymer) batteries. They are pretty much like cell phone batteries, but larger with more cells and higher voltage. The charger has a computer that monitors each cell and controls how much charge goes into it, because if you overcharge a LiPo they can catch on fire... and burn your house down. My charger connects directly to my 12v battery, and at home I use a 12v power supply for it. I use one that can charge 4 batteries at once. http://www.horizonhobby.com/products...arger-HRC44151

3. Batteries: LiPo flight packs and a 12v marine deep cycle battery to run my equipment in the field.


Stuff I would do different: I wouldnt have bought a 1500mw video transmitter. It's way more power than I need. 400mw would be plenty.

I wouldnt have bought that big cloverleaf video transmitter antenna. The small whip antenna works fine, the big antenna doesnt really fit on the drone without the props hitting it.

The cool stuff about all of this... if I want to build another drone or a plane or whatever, as far as the video equipment goes I just need another video transmitter, CCTV camera, and a transmitter antenna.


If you decide to build one, you dont need a $1500 JR 12x RC transmitter. A $300 Spektrum DX8 will work fine. The JR 12x is a professional level radio that I already had for my planes and jets. Yes, I fly planes at a professional level, have been flying them since 1985.

Now, why does it use a CCTV camera, video transmitter, AND a gopro camera? Simple to explain. You wear the video goggles and you see the image transmitted from the CCTV camera. This is your "flight" or FPV camera. The gopro is just for recording a HD video, you download that from the gopro after you land. Video recorded from the CCTV camera is pretty shitty, while the gopro is nice and clear. You could transmit the video from the gopro to your goggles, but the gopro video-out tends to go blank for a couple of seconds when transitioning from dark to light areas, such as turning into the sun or flying out of a shadowed area. That's all it takes to make you crash.

I've got this apart right now while I'm making a new power distribution cable and soft mounts for the motors and camera mount, trying to kill all the vibration.

This is a demonstration of how the camera gimbal works... it uses two servos connected to the flight controller (which has three gyros and acceleromoters) keeping the gopro steady relative to whatever the drone is doing.



And here is the kind of stuff that you can do with it









I dont know how to embed Vimeo here, but these are really nice:

This aircraft is a step up in cost, capability, and complexity from a AR Parrot Drone... but the results speak for themselves dont they?

How long before somebody builds one to use at an adult photoshoot?

I could maybe lend my services to content producers in the Las Vegas area
