Simple FPV

[fliteadmin]

Well here it is. We listen to our viewers and everyone wants to know what FPV system we use. In this episode, we talk about our FPV gear as well as show you how it works. If you haven't tried FPV yet, you don't know what your missing out on.

is that a plywood base?

 

[BindNFly]

and How do you change the lenses? do you just remove the screw???

 

[Josh Bixler]

and How do you change the lenses? do you just remove the screw???

All you need to do is losten the set screw and unscrew it. The base is plywood too.

It is a very easy and reliable set-up. It is simple FPV at its best!

You guys posted a link to a 1.2GHz tx. so does that mean that rx receives those freqs?

 

[PiperCub49]

Hello, guys! Here a quick question to throw out there: I'm normally a balsa guy myself, so I can't afford to ditch a plane because of a dodgy signal. Do we have any clues at to what is causing the video to drift in and out? Maybe it's an antenna problem, a voltage problem, or simply system limitations?

Thank you,
PC49

what battery did u guys use on the tek sumo

I have just started researching the gear involved for FPV tonight, and I have a question about the recommended set-up above. Why the link for the 1.2 GHz transmitter (bevrc), if the HK system already comes with one?

I was wondering the same thing. I am thinking maybe the rx also receives that bandwidth cause it has 12 ch? and the tx is only a 4 ch transmitter? its just a guess. I am trying to get one for xmas so ill test it out and see why.

 

[Johntra]

CHECK IT OUT! I finally found someone that would tell me if it would receive at 1.2 GHz. Well he didn't tell me but i found it none the less.

Others are way smarter than me but in my research I was under the impression that 910 mhz is the only
frequency that was legal in the usa in the 900 tx/rx package. Also 1.2 ghz is not allowed either due to FCC regs.
Which is why you have 1.3 ghz and 5.8 ghz.
I qualify this by directing you to this retailer:

And this:

Am I correct?

 

[Johntra]

It was my understanding that 1280 MHz was the only freq that was allowed in the states in that bandwidth.

 

[Derrick_Miller]

Johntra,

I am just getting into fpv flight myself, my understanding is that the following frequencies are legal in the United States:

900 mHz
1280 mHz
2.4 gHz
5.8 gHz

Now the question that I have, if anyone can answer, what operates in and around the 1.3 gHz range?

Can someone please post the setup of the Swift on the video? motor, esc, prop, battery. I'm planing to build one for simple FPV. Thanks

 

[Burg]

Nene, I had this one in my favs:

Good example to see where you put all the fpv stuff.

I believe you can use the standard motor/esc/prop setup with a larger cap lipo.
Don't choose a high kv motor but a 1200/1400 max with largest possible prop to keep some punch.

Dragon link stuff is not necessary when you fly 1km to 2.5km max with a 5.8gHz 200/500mw system and some good CP antennas. When you use the turnigy 9x modded with some FrSky gear you'll have a nice 'beginners' setup.
Just my 2 cents.

 

[nene]

Thanks Burg. Great video. So its pretty much possible to use the setup I now have on my Swift, 30 amp ESC, 1800 kv motor, but with bigger battery? I am thinking of buying the 5,8 Ghz 200mW set from Hobbyking, then add a cloverleaf antenna to the video transmitter, and that's about it. I would also need a cheap, small and good camera. We all want that, don't we? No, seriously, what camera to buy? As cheap as possible, but not very low quality, something in between.

I am thinking of flying max 2km. I also only have the basic Turnigy 9x setup, so the range for start will be around 1km. I should and probably will soon upgrade to Frsky.

 

[Burg]

Yes nene, you are right.
And I advise to use a skew-planar antenna on the Rx as well.
You can't go wrong with the 5.8gHz 200mw set then.

This is a great camera :

Or when your wallet allows it, get the WDR750.

Hello again, the funds for my FPV are about to come, so its time to make a decision... I friend of mine recommended me this Fatshark kit: http://www.hobbyking.com/hobbyking/...FPV_Headset_System_w_Camera_and_5_8G_TX_.html

What do you think? A good starting kit? I know I would only get about 500m with the stock antennas, but with some skew planar and cloverleaf antennas I should get 1,5 or 2 km?

 

[Burg]

Nene, 500m in theory yes with 100mw in ideal conditions. 1.5km to 2km with CP antennas: no. Advantage of CP antennas is a much more solid connection, less glitches and therefor a little extended range. How much I cannot say. When you use FrSKY gear you must have 1.5-2km range. But not with this set. I remember Bruce from RCModelReviews did a review on YouTube for it ..

How far do you want to fly FPV ? I want 1 to 1.5km and choose the 5.8gHz 200mw set (usd65), CP antennas (usd35) and Turnigy 9x (usd40) with FrSKY gear (usd35). This cannot go wrong. I use a 7" LCD screen (usd 35). Total usd210. I might go for goggles some day, but I'm not sure yet. I find them quite expensive ..

 

[nene]

Thanks for the info. Probably a better solution, you are right. The only thing I like on Fatshark goggles is the inbcluded headtracker. But this can probably be done cheaper with a sports hat and a custom headtracker

On the RC305 I have two video exit, so I can use a TFT monitor and goggles for example. Or a recorder. That's a plus.

So the verdict is, the 5,8 ghz RC305 set, some better CP antennas and the camera you suggested me. I also already purchased a DIY Frsky module with a 5db antenna to get a little extra range on my radio.

Burg, I owe you a beer. I will get in touch with you if I ever go to Netherlands.
