[LatvianRC]

um how much is 4. miles I am from Latvia How much it is in km?

[TheSliekaStyle]

@LatvianRC

eu, beidz taisīt latviešus par debīliem! Sarēķini tak! Kas tu 2. klasē mācies?

[RCcunuk]

@LatvianRC 4 miles is 6.4 km

[ox141jf]

hi could you get adam to do a vid on how to make the clover and 4 leaf tx and rx antenna???

[flitetest]

@smorgardsboard We just reviewed the Hangar 9 P-51 Mustang (nitro) a few weeks ago.

[aesoft2009]

Did anyone notice Josh Scott picking his nose at 4:04?

[cayote64]

The hobbyking fpv patch antenna is a really poor patch antenna. It only just gets a bit further than an omni. Being a "supposed" 14dbi means with a 11 dbi advantage you should get at least 3 times the distance minimum, each 3dbi extra doubles distance.

[USAFA21]

you guys are really using low cost systems lol

[jwjwjwjwjwjwjwjjwjwj]

...that was stressful!

[Trentaur]

Please put FPV in the title :)

[tanman77au]

"they both hurtz really bad!!"...LOL hilarious

[CAGreve1231]

They forgot to mention that 900Mhz is on the GSM (cell phone) band. Turning off your cell phone increases range greatly....

[C4ITA]

I have the 900mhz 100mw kit from HK and actually i reach about 1200 meters with patch antenna but i think it can reach more with some bipolar antenna :)

[pottera00]

You really should have made the point that you cannot fly with a 2.4ghz Tx/Rx and a 2.4ghz VideoTx/Rx. They interfere with one anotherbecause they are on the same frequency

[RCllamadude]

hey, just wondering, i am building "drone" for my 8th grade final physics project, i need an fpv system. looking to get about 250 yards out of it. would the 100mw be enough? or should i go with the 200 mw? price is also an issue. by the way, i saw a parkflyer fpv system on nitroplanes, but it has no specs for mw, frequency, range, and whether it is ntsc or pal. it costs $36 but i am a bit worried about buying it. any ideas?

[VisionLeon]

hello , i want to add a patch antenna to my HK fpv receiver but i don't now the name adapter for my sma antenna to Rx, help please

[chiosex]

test really needs to be done properly with an aircraft, also with so many people now flying 2.4 its not something I would be comfortable using (but want the range) what else is available, and does using a 2.4ghz tx and 2.4ghz fpv system cause problems? I will look on rcgroups but you guys should mention this sort of stuff! Great channel by the way, love your vids guys, keep it up!

[PHeMoX]

Isn't that shielded glass where the cameras are? That's a BMW right? I think range through the air might be more.

[xjet]

Not really a great comparison because your signals are being largely affected by ground-clutter that won't affect the signal from a model. RCModelReviews has a 200mW 5.8GHz system operating without noise at 1.1Kms which is almost 0.7 miles. A 2.4GHz system of the same power will reach further and a 900MHz will reach further still. A full line up of ground-to-air comparisons is in the works. Great video though guys!

[pammpa]

cant hear the voice over the background music

[iflybythebook2]

You guys are way better than a sock puppet!

[tjtg]

You need to do it on a plane to get a real test. I have flown with the 900mhz (800 mw) system at about 800feet and 1k away with no drop out at all (omni Directional)

[poerik]

nice vid

but bad test this is not fpv ! more like fpc

grtzzz

[sxcg]

its not fair for the 2.4transmitter to test in an area which is full of wifi and other 2.4GHz devices like wireless phones.

[TheGrabist]

The Video TX 2.4G won't interfere with my Turnigy 2.4G remote ?

[paintballkidz]

@TheGrabist it will.

[TheGrabist]

@paintballkidz

This is something that I expect to hear on a review

and not only "how good it is" or "HK is the best because he sponsor us"

A review should be non biased

[wwmilanl]

Great video, Thanks. But why you did not test the 5.8Ghz?

[ar22dp]

Good show!

[megatesla]

900 milliuhmegahertz

[zombienumber13]

great videos guys, i just watched all of them and i was so entertained, you guys work great together, are very funny, and have great onfo. thanks to everyone involved in making this show tv quality for sure

[w7mag]

Window Tint

[JollySwagman2006]

Great budget priced FPV setup, will definitely try one of these out one day soon

[TheKrazydreams]

can u show how to setup a 900MHZ 1500mW

[IStealPursesXD]

Awesome. Can't wait to see it in flight.

[TheLucas2696]

Nice video! But you should try a 5.8ghz one too!

[flyingchimp99]

@TheLucas2696 dosint 2.4 give you more range ?? then 5.8 ???

[TheLucas2696]

@flyingchimp99 That's what I'd like to find out! Because I fly 2.4, but you can't fly 2.4 and use it for video.

[Slayer10000000000]

Eh... not really impressed. I am impressed with your test setup though.

[coolwaterhubby]

Hey guys i like the video but are you. Or do you have a video of how to set up video transmitter?

[StewieRc]

maybe build a twin cargo on rcgroups, 2.4ghz on right wing, 900mhz on left wing. get them up in the air and try to fly as far away as possible.

[topgun7419]

proceed with such tests can not be better. brilliant test boys.

[knudball]

You mentioned in the video that there are alternate lenses available. Where can I find them. Also, is there a case available for the board cameras? Thx!

[bonafidepirate]

Agreed! Ground tests don't translate well to range in the air! I've flown two miles away and back, over a thousand feet high without a single frame of video lost, only to have to signal drop out almost completely on landing approach when I get close to the trees and house... ;)

[dorsai]

Thanks for showing the test, but ground interference is limiting your range.

[youtwoba]

Maybe you guys can make a video of exactly every component needed and a full description of each component to help us understand everything we need to get started in FPV and prices. I may be interested in this, we'll see. Thanks for the info.!

[kenrom]

Thanks for doing this, guys - loving your show, too! Since you're on the subject of range, I'd like to see how various antenna options compare on the 900Mhz system...

[Lithoushine]

you should do the same test but throw in you transmitter for your plane and see how they interfere. more so your  2.4ghz radio for your rc link and then the 900mhz transmitter for the video on at the same. i think you will find that the 900mhz will cause the 2.4 to have nasty lock outs

[MartinAStout]

Nice to see an actual side by side comparison, but I agree with some of the others, a "ground level" test seems to draw so many inaccuracies. Taking into account how well the area is populated, you never know how many WiFi hotspots you were just surrounded by, or what other wireless equipment that is being used.

[bluefisherking]

thanks for doing this practical hands on test.

Would REALLY like to see how the 5.8GHz compares.

UK = can't use 900MHz, and flying on 2.4GHz, so 5.8MHz is the logical choice, especially now that HK has some equivalent stuff in 5.8...

Pretty please, update or compare with 5.8?

[PHeMoX]

@bluefisherking I'm thinking there will be follow up videos to this one anyway, as you can't fly using 2,4Ghz and use a 2,4Ghz video system at the same time and indeed 900Mhz isn't allowed in many countries because emergency services use that.

[randyneighbour]

more please could yuo use more powerfull transmitters as well as a 5.8bgz system there and see some real wor;d reviews

[eryn4586]

That was an awesome demonstration.  Thanks!

[UtRadioGuy]

Wouldn't it be best to test it with the TX higher than the RX? That would simulate you flying, instead of being on level ground. Park the car with the TX on a big hill and see how far you can get. I bet you get double the distance, if not more. A level ground test dosen't mean much to me, I want to know how it does while flying.

[caranze]

Too bad maximum output power in Sweden is 100mW. Also, 900MHz is illegal and I'm flying on 2,4GHz....

[tehlump]

I wasn't there obviously, but it seemed to me that while both frequencies had signal lock the 900mhz had higher quality, less glitching and jumpiness? Also, if you're controlling the aircraft with 2.4Ghz are you prevented from using the 2.4Ghz transmitter? Or do they share the space on different channels? Thanks for this out of the ordinary test, I'm interested in FPV but thus far haven't taken the plunge...

[simio1337]

@tehlump

The reason 900mhz had a clearer picture is because its a longer wavelength than the 2400mhz (2.4Ghz) system. This lets the signal penetrate and reflect obstacles better.

[bicyclemonkey]

@tehlump

Yeah, I've always heard that if you use the 2.4GHz FPV you can't use a 2.4GHz TX, you'd have to use a 72MHz TX if you use the 2.4GHz FPV stuff. Looks like the 900MHz FPV will be the way to go.

[kamu38]

@tehlump 2.4Ghz should have a better quality picture due to the increased bandwidth, if I am not mistaken.

[michi386]

but i need a patc for 900mhz

any recommendations?



[marty12004]

Good work as always!!

[Hitohippo]

@marty12004 Not good? Excellent!!!
