Do you know of a good quality budget RP-SMA FPV antenna?

Thanks!

I'd like to send you a PM, but either they changed the UI and I don't find that option on your profile, or you disabled it?

Can anyone help me out?

I am getting waves and jumping near the top of my video.

1280 mhz RMRC vtx with Oracle Diversity and RMRC upgraded SAW vrx's on receiving end. Inverted V transmit and Heliax and Cloverleaf on the rxs.

Feeds a 5.8g 25mw relay to groundstation with CPCL on rx.

video from the relay feeds a Japan SD-4 DVR and the video out from that goes to a Haier 10" monitor.

I use a DragonLink LRS with Dragon OSD.

I can cause interferrence from the DL by placing tip of the antenna within 4 inches of the 5.8 receiving antenna (right at beginning of vid) but I'm aware of this and it is not what is concerning me right now.

The waviness at the top of the vid is what I'd like to cure.

Thanks for any help. I should also mention that I'm using Cat6 cabling for my Vtx/OSD/Cam.

Video Waviness (0 min 49 sec)

Wavieness is often a problem with video sychronization. Drop the diversity and go right to the VRX with your screen. See if it goes away.

I'm looking to upgrade from a small 5 inch lcd screen to video googles. It seems like Fatsharks are the most used. I am looking at the Fatshark Predator V2 (http://www.hobbyking.com/hobbyking/s...d_5_8G_TX.html) and I like it but it does not seem to offer as much upgrade capacity as the dominator. I know eventually I will want to be running at least two receiver antennas and this is only possible through a ground station but I do not think I would be able to connect the Predator V2 to this. Is the dominator worth the $300 dollars for just the googles?

if you buy get dominator or vuzix920

Hey Guys I need a little guidance on where to mount my 1.3 800mw VTX on my Penguin.

I have been taking my time building my Penguin to make sure I have everything setup perfect (always need to tweak things with FPV). I will be running IBcrazy's BlueBeam antenna set and was curious if mounting the VTX with BlueBeam Antenna behind the prop in line with the Rudder? I was thinking mounting on a wing would work too, but think behind the prop on the fuselage would be cleaner.

Would love to hear what you guys think would be the best spot for the VTX and Bluebeam!

Thanks Again,

I have the Fatshark Predator (not V2, mine has the integrated head tracker). I've never used any other goggles, so I can't compare, but I like them a lot.

The Predators (spec sheet here) have a 25 degree FOV, which means the image is "further away" and sharper. It looks more like you are sitting in a dark room with the TV farther away from you. The upside is that details like OSD numbers are crisper.

The Dominators (spec sheet here) have a 30 degree FOV, which means the image will look "closer". Since it's the same resolution LCD, the resulting image will be blurrier.

Some people like the immersiveness of the Dominators, some people like the crisp image of the Predators. I chose the Predators because they were slightly cheaper. Both sets of goggles have a full AV in/out port via a 3.5mm headphone jack, so you can wire your goggles into your groundstation instead of using the built-in receiver. There is a little switch on the goggles to turn off the receiver.

That is where most people put it. Out on the wing is another good choice.

Agreed. The EVG920s are also excellent.

Thanks for the reply Alex! Much appreciated!

Hello guys .

I am totally new to FPV and I am considering to invest in the fastshark complete system including GPS , 600mW transmitter, elogger, osd pro and so on.....

My problem is that I have some myopie about -6.5 with a beginning of astigmaty .
I saw on Hobby-King that you can get some-6 lenses but I don't know how to correct the astigmaty problem .

Does anyone suffer from the same problem and is there a solution ? I don't want to invest a lot of money just to find out I can't see clearly .

Thanks for your advices guys .

Not sure I can tell you for sure but I can tell you my experience. I am near sighted and wear contact lenses. With my contact lenses in, I cannot read paper in front of my face without using reading glasses (2.0 power I believe). If I wear my contact lenses, I can see the screens just fine. Without my contacts in, I suspect I would need to use the lenses that you can buy for the fatsharks. I have the lenses but have never tried them since I always wear my contact lenses.

Hope that helps some.

Save your money and forget all the bells an whistles. You don't need them, nor do you really want them for learning. Buy a camera, VTX, VRX, and a set of goggles or a portable TV from a reputable FPV vendor (ie not HobbyKing or RC4Y, ect) and go fly your airplane. Start adding on once you have 10 flights under your belt.

That's priceless information and very accurate. I tried starting off with a complex system from the get-go and it was very soon that I learned that I had wasted a lot of my money.

I know this is the right thing to do but there is a guy selling the complete set for cheap so either I get it all or nothing .

Anyway, I am not sure about my vision and that is cooling me down .
