Quanum
FPV goggles
One of the most expensive parts of my FPV-system is my video goggles. I have been using the Fatshark Dominator for a couple of years and recently upgraded to the Dominator HD. I love the big field of view and sharp image of the Dom HD. But in addition to those I wanted an extra set. For my kids when they’re playing with FPV on their RC cars and as “guest goggles” in the field when I want someone to be able to see what I see when I fly.Fatshark
Dominator HD
But I wanted something cheaper than the Dom HD. So when Hobbyking added the $29,-Quanum Goggles I had to try them out. You need to put them together yourself but that is very easy. They come with three fresnel lenses. I tested all of them before I did my final mounting of the goggles. Only one of the fresnel lenses wassuitable for me.
They worked very well but I missed the high resolution of the Dominator HD. So I searched RCgroupsfor some
info and found that people have had success replacing the screen with one that have a better resolution. It is important that you get one that don’t cut the image as soon as the video signal is slightly noisy. I had this screen lying around and tested. It was completely useless going straight to black as soon as the signal was slightly noisy. So I ordered the one recommended by people on RCgroups.
That one works very well. It won’t go black screen on you before the signal is so noisy that you can’t see anything anyway. I mounted it in the end of (outside of) the goggle frame because my eyes liked the extra cm of distance to the screen. But you can also fit in into the original place where the included screen is mounted. I added a layer of heat dispatching silicone and then a layer of duct tape. Not the best protection but good enough for my use. I also added some foam to make them more comfortable and a slightly more advanced headband to make them sit better on my head. The headband came from a pair of ColorCross VR-goggles that I had used to do some experiments. One example: no, you can not modify the Color Cross or the Google Cardboard goggles to be used as FPV goggles with one screen. The focus point of the optics are made so that you won’t be able to focus both eyes on the complete screen. You can buy a headband here: New DIY Head Mount Strap For GoogleCardboard
I also removed the phono video input and changed that to a mini jack video input just like my Dominators. That way I can use these goggles on my base stations with the same cables that I use on my Dominators. I also did some tests with other optics. One bigger fresnel lens to get rid of the black border around it and a proper magnifying glass toget better optics.
But both of them did not fit my eyes and made it difficult to focus on the screen. So I kept the original fresnel.CONCLUSION
The $29,- goggles with the upgraded $35,- screen makes for a VERY good pair of $64,- FPV goggles. So good that they can compete with my Dominators. The resolution for 4/3 with the upgraded screen is 640×480. Not as good at the 800×600 in the Dom HD, but very good for $64! The biggest downside with these Quanum goggles is the fact that they are much bigger than my Fatshark goggles so they won’t fit inmy ground station.

micro quad 3 Comments Lots of people have asked. What is the spec for the tiny 25 gram quad you used in your demo at DARC ? And in this flight at the Nordic Media Days ?HERE IT IS:
Quad: Blade Nano QX – BNF Version (Horizon,
A-main
)
You don’t want the RTF version. You really want to control this with a proper radio. So buy a suitable DSM2-module for your favourite radio and use that. My favs are my second hand Futaba 9C and my FrSkyTaranis.
DSM-modules:
JR / Spectrum
,
works out of the box.Futaba
,
needs USB-stick
to change the channel order if you want to control the Blade with it.FPV:
Video Tx
Camera
Wide angle lens
Voltage step up and filter Then you connect power from the main battery to the step up adapter and 5V out of the step up to the video Tx and the camera. The last cable is video from the camera to the Tx. And off you go. If you don’t have a FPV base station you need at least a video Rxand some
goggles
.
Vaaaat? Tx? Rx? Soldering? If in doubt, start with this one.
Not the same video range, not the wide angle lens, but plug and playfor noobs.

As some of you might have understood I’ve done some experiments with multirotor helicopters for the last couple of years. Mainly because I think it is extremely interesting what you can do when you combine these machines with cameras. Stuff like this: And if you want the best images you need to be at the right place at the right time. And for images like this you need to be there with your copter. So the copter needs to be easy to carry. I wanted to build a FPV quad that I could carry in my ground station case together with my radio and some batteries. I have built several mini-multirotors that fits in that space, but now I wanted to build a bigger quad that should be able to carry a bigger video Tx, gopro andeven a Sony RX100.
I ended up building a foldable quad. So far I am very pleased with theresult.
I’ve built several multirotors during the last two years. Quad, hexa, Y6, X8, tri, octo. I’ve built in wood, alu, carbon fiber andcombinations.
But i like wood. It gives less jello in my recordings because it is slightly flexible so it absorbs some vibrations. And the flexibility also makes sure that it survives a lot of crashes. But it is not too flexible, so it is stable. And it is cheap. And environmentally friendly. Doesn’t block radio signals. Doesn’t transfer current. And it is easy to work with. So, here is my wood based foldable quad: There is a bit of jello in the recordings here. It is 2.7K @ 25p with no ND filter. Will probably get rid of it with some tweaking of themount.
UPDATE:
First FPV test flights. Now with GoPro Hero2 at 720@50p and a horribly misplaced ND filter. But: absolutely no jello! The arms are tightened with four screws. Folding and unfolding takesapprox 30 seconds.
SPEC:
Motors: Sunnysky 2212 980 kvESC: HK F30A SimonK
FC: DJI Naza GPS
Props: 8 inch
Motor-to-motor: 58 cm GoPro mount with Tilt4S Batteries

First of all. If you want to know what I’m up to next, follow me ontwitter: @eirikso
SO, I POSTED THIS VIDEO ON YOUTUBE TWO DAYS AGO: And it have gone completely viral. It was made in a hurry and leaves a lot of things that might need an explanation. THE PLACE AND THE MOOSE The video was shot just outside of Oslo. We have a lot of moose roaming around the woods here in Norway. And some of them very close to the city. They’re shy of people, dogs and other living creatures, but are pretty used to the sound of cars, trains, helicopters, planes etc. To see a moose is not very uncommon in Norway. This moose is probably a 1,5 year old female. She seems more curious than afraid. And we spotted her again from far up in the sky later. Still calmly walking around eating in the same wood. THE TECHNOLOGY IN GENERAL One of my hobbies for the last year have been to build and fly multirotor helicopters. When I fly them I do it either by flying Line-Of-Sight (LOS) or First Person View (FPV). When flying LOS you simply take off and fly the thing around while watching it from the ground. For quadcopters this limit the range because the copter is symmetric and you loose the orientation pretty fast. However, as I’ve gained experience you start to feel the direction based on speed and the way you control the copter, making it possible to fly further away. I fly LOS when I want to do acrobatics and train accuracy and pilot skills. Here is an example of some acro flying with a very small quadcopter: KK2 Acro FLights from Eirik Solheimon Vimeo .
But for the video with the moose I fly FPV. Meaning that I have a dedicated camera connected to a video transmitter on board the copter. I feed the video signal into a pair of video goggles and navigate the copter like I was sitting inside it. Based on the video signal. When flying this way I always have spotters beside me that keep an eye on the copter and what is happening on the ground. In addition to the goggles I have a screen and a digital recorder on the ground station. That recorder also has a mic and records the audio from the spot where we are standing. Ensuring that we got the recording of the quite enthusiastic spotters and my rather nervous comments about battery status and the fact that it is darn difficult to navigate this thing between and under the trees.THE CAMERA
On the copter there is also a GoPro Hero3 to record HD video on board. The video downlink is only SD-quality. In the video I cut to the footage from the DVR at some points to show how it looks from my goggles. Here’s a screen shot from that feed: You can see the battery status in the top left corner. We spotted the moose at the end of my flight. At 13,2 volts the batteries will be harmed and the copter will descend automatically or simply crash. Because the HD footage is done in the GoPro on board the copter it was pretty important for us to get it back in one piece. On this copter the GoPro is mounted “naked” without the water proof box. To save weight and make the mounting easier. So I don’t want to crash it inthe snow.
The recording in the GoPro is 2,7 K @ 25 FPS. It is slightly stabilised in FCPX and rendered at 1920×1080. The camera is mounted on a vibration dampened platformunder the copter.
THE DETAILS
The copter I use here is this one.
It is a quad rotor helicopter. Based on a X468 frame that makes it possible to wrap it together for easy travelling. It is controlled by a DJI Naza flight controller that has gyros, accelerometer, barometer and GPS to assist the stabilisation of thecopter.
I am using an old Futaba 9C remote with FrSky Tx and Rx modules. After my previous post about the copter I have changed to three blade, nine inch props (9x5x3). They give me less jello and vibrations in my recordings. In general I find it easier to get rid of vibrations with smaller props running at higher speed. So I run the copter on 4S batteries. Usually two 2200 mAh in parallel. That gives me up to 12 minutes flight time with GoPro and FPV equipment. But 12 minutes is with completely new batteries and when I am pushing the limit. Usually I fly around 8 minutes and land when my batteries are close to 14V. In this video I push it all the way down to 13,2 V when I land. I have also changed the ESCs on the copter. From Turnigy Plush that I mention in the article about the copter to HobbyKing F30A withSimonK-firmware
. That change
made the copter _way_ more stable.SONY RX100
I am also flying this copter with a Sony RX100. It is heavier than the GoPro, giving slightly lower flight time. But the RX100 has excellent image stabilisation built in and you get rid of the GoPro fisheye-look. Here is a RX100-video from the same copter and samearea.
THE DANGERS
Multirotors can be dangerous. The props are spinning fast. And they might cut your skin if you get too close when they are running. On my copter I have pretty soft and cheap GWS props. They’re not as dangerous as the carbon reinforced props that many people use. But if you are flying high the pure weight of the copter is dangerous if it falls down. And they do. That is why we are flying outside of the city over fields with no people. And always have spotters on the groundwhen we fly FPV.
The lipo batteries are very powerful. And can explode or catch fire ifthey are damaged.
In addition to this there are rules regarding remote controlled devices. They are different in different countries. In Norway you can fly up to 400 feet. And you need a special license to be allowed to put a camera on anything that flies. If you want to to professional AP work you need an extra license from the civil aviation authority. THE FUN AND THE PROBLEM Lots of people immediately say “I want one” when they see how fun this is. And I can really recommend this hobby. But you need to be patient. First of all it is very difficult to fly these things. It has taken hours and hours of training to be able to fly the way I do inthis video.
And even more hours fixing the broken copter after crashing. That is why I build them myself from the ground up. For the first couple of months I never returned with empty batteries. I always returned with abroken copter.
RCgroups is one of the best recourses if you want to start. If you are Norwegian I can recommend our build log over at NRKbeta.no To start training I can really recommend this small and harmlesscopter: WLtoys V929
. It is a
toy, but it is four channel and is controlles just like the bigger copters. If you learn to fly this thing it will be easier to fly bigger and more dangerous copters. Moose vs. quadcopter HACKING THE HOBBYKING TALON TRICOPTEROctober 20, 2012

This is one of the nicest multirotors I’ve built so far. Lifts my GoPro with ease. Flies very stable and powerful enough for acro. And I love the fact that you can fold it in seconds and fit it in a suitcasefor travelling.
But to make it perfect you need to hack it slightly. Turnigy Talon Tri LOS and FPV from EirikSolheim on Vimeo .
THIS IS MY SPEC:
Turnigy Talon Tricopter T-Motors MT2016-11 900 KV Tail Servo: TGY 306GHK F30A
ESC with SimonK firmware FreeFlight 1.3 FC running Baseflight Multiwii Battery: TGY 4S 2200 mAh Props: Have been experimenting with different ones. Best experience with 10″ Graupner, GWS 9x5x3 and carbon 8×4.5 Slowflyers.
The frame in general is very nice, but the tail servo mechanism is not good enough. Fortunately you can fix that by adding two thrust bearings and a longer 3 mm screw. The problem is that the original tail mechanism is nearly impossible to get really tight and still smooth to move. If you add two thrust bearings this problem is fixed. I used these.
Then you need a 3 mm screw that is longer than the original. Approx 30 mm plus head. The original is 25 mm plus head. I used a 40 mm screw that I cut down to 30 mm. Now you simply assemble like shown in the images. Screw with thrust bearing, mount, original bearing around the screw, thrust bearing, another of the original bearings, motor mount and then a 3 mm locking nut. Tighten till you have it completely without slop but still smoothto move.
In addition to this I’ve mounted the motor plates the opposite way of what’s indicated in the manual. In a serious crash it broke one arm exactly where it’s weakest: where it has a slit to fit the folding mechanism. I hadn’t had the time to buy extra arms, so I fixed it by fitting a 12mm carbon tube covered with epoxy inside the arm that broke. So, pack it and get out there and fly! Hacking the Hobbyking Talon Tricopter YET ANOTHER NEW TOY: KK2 MICRO QUADJuly 17, 2012

Just recieved my KK2 Flight controller from HobbyKing. I planned to put it in one of my existing quads, but figured I had four ESCs and four motors lying around. So I could just as well build a new quad for it. The only thing I needed was a frame. So I found a bottle of Amarone, made a good meal, had a nice dinner and made a quad frame out of the box where the bottle of Amarone usedto be:
SPEC:
Flight Controller: KK2 From Hobbyking($30,-)
ESCs: 10A From HobbyKing(4x)
flashed with SimonK Firmware($26,-)
Motors: Mystery A1510($52,-)
Props: 5 inch 2 blade drilled to 3 mm ($3,-)TOT: $111,-
Using 500 mAh and 1300 mAh 3S batteries. Gives 7 minutes of pretty agressive flight on a 1300 mAh pack.UPDATE:
I crashed the Amarone-frame so many times that I ran out of spare parts. I have now moved the parts to this carbon frame.
I also managed to destroy the KK2-controller. While waiting for a new one I’m experimenting with a baseflight-flashed FreeFlight controller and a Rabbit on this small quad. Both seems to work well. The FreeFlight is not available anymore, but with baseflight/MultiWii it is basically a very bulky Naze32 with less sensors. So, buy the Naze32 if you want a very good MultiWii based FC. CONCLUSION ABOUT THE KK2-CONTROLLER Very easy to set up. Love the fact that you can debug and adjust right there on the FC thanks to the LCD. Very stable rate mode but too sluggish auto level. I really hope Rolf Bakke have the time to implement the AHRS algorithm that utilize both the accelerometer and the gyro when in auto level mode. Right now the auto level mode is only good for slow hovering and maybe some help if you looseorientation.
But as you can see from the video in this article. That $30,- board makes my micro quad built from cheap parts steady as a table and loadsof fun to fly!
And the Amarone-frame? Takes a lot of beating, but I managed to crashit bigtime.
Luckily I had some spare parts from the same wine bottle box so I managed to fix it and make it even better… Yet another new toy: KK2 Micro Quad NEW TOY: MICRO HEXA MULTIROTORJune 5, 2012

Just finished my Micro Hexa. Small, not deadly like the big monsters and lifts GoPro and FPV equipment.SPEC:
Frame: BlueSky RC Micro HexaM1822 Motors
from Leadershobby (I decided to give them a try. $3.45 is kind ofcheap…)
Alternative motors that might work: Heavier, more expensive, more powerful and high quality: Roxy 2216 Heavier and more powerful but cheaper than the Roxys: Turnigy from HK Or these on 2S batteries: smaller Turnigy from HK 5x3x3 GWS or gemfan props10A HobbyKing ESCs
flashed with SimonK
Dji Naza FC for now. But I also have OPCC, FF and others. Turnigy Nano 1300 3S batteries5A BEC
to power the GoPro
FrSky and Futaba 9C
Total Weight: 577 g (645 when I add my FPV equipment) _Rough price estimate:_6 x Motors: $60,-
6 x ESC: $48,-
Frame: $25,-
Cables and connectors: $10,-TOT: $143,-
Then you need a flight controller. I’m using the rather expensive $240,- Naza. But will fly fine with a much cheaper FC. A rabbit for$90, a Naze32
for $75,- or even a KK for $15,- Flies 5 minutes on a 1300 mah Turnigy Nano and 8 minutes when I tested it on a 2200 (both tests with the GoPro on board). Will probably get 10 minutes of FPV sight seeing if I remove the GoPro. The motor mounts didn’t fit, so I had to drill new holes. And I hate prop savers so I modified the motors to accept collets. The shaft on the motor is 2mm. I simply removed the built in prop saver using brute force… After balancing the cheap motors and the props I have nice and smoothvideo and no jello.
Here’s 10 minutes of different clips from my first tests. Raw footage dissolved together. All flying done line of sight: New toy: Micro Hexa MultirotorPOSTS NAVIGATION
