Is this a good FPV system?

Is this a good system?

What else do I need when (if) I buy this?



Thanks.

Without more information is difficult to answer. What is your aircraft control system, 2.4 gHz, 72 mHz, UHF? What is the RF enviroment where you're flying? How are you going to view the video picture? monitor, goggles? How will you mount the Video board camera on the plane/truck? (HK has board camera mounts) Pan & tilt or fixed? (servos). You see what I mean on the information.

I bought that exact same kit. I use it for my Quad Copter for scouting farm fields and it works fine for that. But like everyone says there is a lot of other factors that will affect it works for you.

Might need a filter if you are using it with a 2.4...

1.2ghz is a much better frequency (at least here in USA) because of the very low background noise and its ability to penetrate through objects.
Since you are using 72mhz, you don't have to worry about interference.
Actually, you could get that kit since it has a good camera and a receiver and also buy
http://www.hobbyking.com/hobbyking/s...700mW_FPV.html
Im 85% sure that the receiver and the 1.2ghz vtx work together, I have to check that to be 100% sure though.
Since you live in Thailand, I don't think that the authorities are too concerned what radio frequencies you are using but its still a good idea to check what frequencies you can legally use.

Ok, I checked it and ch4, 5 ,6 and 7 on the receiver work with the 1.2ghz vtx.
Some people have complained that the antenna that comes with the 1.2ghz vtx isn't that good so you may want to spend 20 minutes building a inverted vee antenna.

900 mHz Video will work fine with it. Here is a white paper from DPCAV on 900 mHz:

the reason 1.2 is so clear is probably because 1.2 is illegal here in the us :-P At least all the vtx ive seen fall into the banned frequencies.

Correction, I found one that has ONE channel legal in the US but it still requires an amateur radio license

Just remember that if you buy a 100 or 200mw vtx dont expect to fly past a mile
And jhebbel, there is actually two channels

The one i found only allowed one wit ha ham lic. still would rather have a wider freq array to choose from in case a channel has interference in an area. Personally i've never had an issue in the 5.8GHz and while its range is shorter than uhf/vhf, I can still get several miles and the picture quality is a major difference.

Also, antennas play a much bigger role in range than power, Since to double your range you have to at least quadruple the power output, but this usually means heavier equipment and could lead to blead into your radio frequency. it is much easier and safer to increase range by using polarized antenna and directional instead of omni's. You can easily get 5 or so mile with clear line of site on a 100mw
