Someone was asking a few pages back about 25mw 5.8ghz transmitters. Well this guy just went 6.3km with one. He is using a Cloverleaf transmitter antenna and a 12-turn helical (drat!) on the receiver. https://vimeo.com/38284562 Makes me feel kind of like a chump since I still haven't gone further than 4km with 200mw.

Dunno about flight times, haven't flown it in this config yet. I'm hoping upwards of 30 mins of sport flying and much more at an efficient cruise.

There aren't really any goggles that work with glasses. On top of that the goggles available are pretty crappy, really need a tech breakthrough in this area. You could always mod the video goggles into some ski goggles that fit glasses. An LCD screen is always a good choice too, just not as good in bright sunlight so a shade is needed. I wouldn't go any smaller than 7" for FPVing, a 13" is nearly perfect. 2.4ghz RC isn't recommended for FPVing but it will work as long as you know the limitations. Don't try to go much past 1km with clear LOS and don't try to fly behind any objects. No it won't work with the MSR because that's Spektrum 2.4ghz and it's proprietary.

Be sure to read the discussion on that Argtek booster here: http://fpvlab.com/forums/showthread.php?4587-The-Argtek-2.4GHz-booster-thread It has failed on people without warning resulting in the loss of several planes. We're experimenting to try and figure out the causes and look for other solutions. For other 2.4ghz RC tech as it pertains to FPV check out these two threads: http://fpvlab.com/forums/showthread.php?1333-Spektrum-DX8-range-testing http://fpvlab.com/forums/showthread.php?4507-FrSky-User-Thread If you plan on using 1.2ghz video with any 2.4ghz control you MUST think about getting some sort of rf filter like a low pass or notch filter. 2.4ghz gets swamped by some 1.2ghz vtxs so you've gotta do something about it or you'll kill your range. If you're serious about using 2.4ghz for RC then check this out: http://fpvlab.com/forums/showthread.php?2814-Antenna-change-on-FrSky-rx Also 5.8ghz doesn't have terrible range, the record is 18km on 200mw right now.

They use hardly any bandwidth at all for control. The most basic of RC transmitters are on 27mhz, 36mhz, and 72mhz. There are a few long-range RC radios that operate on 433 and are digital frequency hopping. Live HD video is not possible with today's technology without large, heavy pieces of equipment and high latency. Here's a scale Eurofighter FPV build. Lots of attention to detail and excellent craftsmanship. http://fpvlab.com/forums/showthread.php?4590-Eurofighter-FPV-build https://www.youtube.com/watch?v=8d_UmQFQb0M

Yeah maybe theoretically but you've got to remember this is hobby grade equipment and only designed to be used within a half mile or so. Sensitivity of the receivers and the antennas used aren't the greatest. What you're talking about would need a custom designed tx and rx.

Dude, the X8 is sick, you're gonna love it. A local (Daemon) has one and it just floats around with barely any power. He was slope soaring it at our last meet at about 9000ft ASL. Someone else had the new Skywalker 1900 with the wood wings which was pretty cool, but it was still outperformed by the X8 with a smaller battery. The next thing on my list is Google tracking on my Android, but I'm using Skylark gear right now and they're pretty sketchy. They've been saying for months the tracking app "will be out soon." I just maidened my new plane yesterday. It's a Popwing/Tek Sumo with a 10" blunt section my buddy cut for me. Makes it 46" wingspan and 1200 grams with 2x 2200mah 3S. This is also my first plane on 1.3ghz. I took it out past 2 miles on the maiden and did a flyover of Red Rocks Amphitheater and Bandimere Speedway. I want to fly over Bandimere Speedway later this summer at night when the jet-dragsters are in town. I will need to invest in a GoPro for that for sure. https://www.youtube.com/watch?v=RMD5zK_2z8s

You should be fine as far as the airports are concerned. Yes 400' within 3 miles is the FAA advisory, it's not actually a law but it is drat good advice to follow. You need to check local rules and laws before you fly though, the FAA doesn't restrict it but your local parks commission sure as hell can. Secondly a good size park will be ok to fly in, maybe an acre or so minimum. When you start to FPV you will notice you have much more freedom and the launch site isn't as critical because you're no longer limited by your eyesight and can fly further and higher.

polyfractal posted:Awesome, good to know. Will the amount of houses/trees in the near vicinity affect FPV due to interference? Will I have to keep the plane in line of sight at all times (even if the plane is pretty far away)? There is a good quote I read on another forum: "FPV is self-regulating." Each individual has to learn, build, and test their rig themselves. If you start small and grow progressively you'll do much better. Right now your goal should be to fly a plane LOS successfully.

It's just a tricky hobby. I could box up my plane I just flew 2 miles with and send everything to you and you may only be able to fly 1000ft just because you could be in a heavy rf area with lots of interference. Lots of new guys get obsessed about range and either confuse themselves or end up wasting money because they have this unrealistic goal stuck in their brains. The range comes naturally; you're going to turn around when the video gets bad or you're going to crash. The more you learn the better set-up your plane will be and you'll be able to take it out further with more experience. Those first few flights you're going to be making GBS threads yourself with a combination of fear and excitement and range will be the last thing on your mind.

Hey guys, recently you may have noticed that the AMA is taking a fairly aggressive and negative approach to FPV. Well a few FPVers have decided to push back against the sensationalism and ignorance and have launched a petition to the AMA to re-think the rules and the way they approach FPV. Please take the time to sign: https://www.change.org/petitions/petition-to-the-ama-regarding-fpv-model-aircraft The petition has sparked a response from the AMA: http://amablog.modelaircraft.org/blog/2012/05/31/ama-presidents-statement-on-fpv-flight/ You can see our discussion here: http://fpvlab.com/forums/showthread.php?5837-Petition-to-the-AMA-regarding-FPV

Be careful running that vtx module off a 1S lipo. The Rangevideo versions do not have the regulator like the FPVHobby.com or others do. Running it off a fully charged 1S (4.2v) will damage it, lots of people have had them burn out.

Here's my latest plane. It's the Pitts Challenger. My buddy is down the street from RCFoam.com's warehouse so he hooked me up with some free Depron! Specs: 30" wingspan 34" length 705g AUW with 1300mah 794g AUW with 2200mah Turnigy 2826/6 2200kv motor with 7x5 prop ~350 watts Rangelink 200mw 5.8ghz vtx module with CCD Killer camera The motor is way too inefficient in this set-up, only getting about 5 mins off 2200mah! I have a similar size 1000kv motor and 9x7.5 prop that should work well. I also added some landing gear for the maiden.       https://www.youtube.com/watch?v=T59-LPM-1d0

That video was flown on 1280mhz at about 600mw. I was using a cloverleaf tx antenna and crosshair antenna on the receiver. This combo is probably good for 20+ miles easily. I've also used 2.4ghz and 5.8ghz. You probably had bad luck on 5.8 because you're using the Fatshark setup which is low power but more importantly the receiver isn't very sensitive. The Foxtech brand 5.8ghz stuff is excellent, I can fly 1+ miles on 200mw on Blubeam omnis and I've taken it out to 3.5 miles with a helical battery limited, still had a great picture. Also using a Rangelink 433mhz UHF system so I never have to worry about my control link.

Haha right on. Naw that place off Quebec overcharges like mad, even more than everyone else. Colpar Hobbies is pretty good. None of the shops really know anything about FPV or care to learn. Pretty stupid IMO, every RC in 5 years will have a camera standard I bet. I've brought my planes in and they just kinda give me a hairy eyeball and try to make me admit I broke the law somehow. All I buy from shops now is raw building materials and propellers, everything else I get online. Check out FPVLab.com for more info. Look up "Dehogaflyer." Yeah you could use a FLIR and RC plane to hunt but I think the going rate for a cheap FLIR cam is about $8000. You can definitely fly in the mountains. High turbulence is a problem but some of the best sights are up there: https://www.youtube.com/watch?v=lX7JFe4kYa4

I'm not sure if many people have heard but there is some pretty intimidating legislation coming out with regards to unmanned aircraft. Unfortunately most do not differentiate between hobby and other kinds of uses. There is a bill in Oregon that would effectively ban every single RC aircraft of any sort with any sort of camera on board: from a full on FPV craft to a iphone drone to a Air Hogs $75 free-flight toy. The lists of states with these bills so far is: California, Florida, Idaho, Maine, Missouri, Montana, Nebraska, North Dakota, Oklahoma, Oregon, Texas and Virginia. Please send them your thoughts! Remember to remind them that we already have very detailed privacy laws in this country that would more than cover any mis-use of UAVs, on top of that Congress has several times re-asserted that recreational model aviation shall be unregulated by the FAA. http://amablog.modelaircraft.org/amagov/2013/02/06/the-list-of-states-considering-uas-drone-legisalation-grows/ https://www.youtube.com/watch?v=ygoJoVk_qSo https://www.youtube.com/watch?v=Cm8Mxqwttnc The drive behind these laws is coming from many different places. From paranoia about military drones spying on citizens to ACLU concerns over police using them to ugly neighbors thinking you're looking at them sunbathing all the way to corporations who don't want to be caught breaking the law.

NitroSpazzz posted:Last time I checked (it's been a while) it is illegal to use a UAV/heli/multi for commercial AP work thanks to a lot of people flying too high and where they weren't supposed to. You might be able to get a lisence but it will be stupidly expensive and likely not worth it in the end. On top of that mostly why UAV AP is illegal is because of lobbying on the part of full scale AP companies and worries about jamming up the NAS with a bunch of commercial UAVs before the FAA is ready for them. If you watch the Discovery channel or other modern reality/documentary shows you will be able to spot footage from multirotor, blimp, and fixed wing UAVs clearly violating the ban.

Oh I agree for sure. I want to make money off my UAV but am worried about trying. I have a friend who got a cease and desist letter from the FAA for filming sub $1000 gigs and then these guys on Discovery are making multi-million dollar shows with multirotor shadows on the ground and the FAA turns a blind eye. Goddamn selective enforcement!
