900MHZ 200mW Tx/Rx & Camera Combo from H.K.

Is 900mhz any good?

What kind of range are you getting?   

Do I need new antennas?

What are those lines in my picture?

What about the camera?

All I can say is,Yup.I am liking it. The wiring harness it comes with is nice n easy to get it going quick.

Bout a kilometer so far,but you probably want to have nice filters if you are on 2.4 for your control.Got mine from readymaderc.com

If you want to get further away and have better reception,yes.

The 200mw vtx does not filter the power like on a lot of your 5.8 vtxs.So you might want to get one of these..  http://www.hobbyking.com/hobbyking/store/__26246__L_C_Power_Filter_for_FPV_A_V_Systems.html 

The camera is really pretty good.There is no easy way to mess with the white balance and as you can see it gets blown out in the sun sometimes.I did also change the lens to one a bit wider.It has nice color for the money.    

I took it up and tossed it around.Dives,rolls,inverted...Trying to see how the signal behaved.

I then take it out to 1 km before turning back.No loss of picture. 

To be honest,I never flew with the stock antennas,just used em for ground tests,as they are kinda heavy(26g or so).

During ground tests we found them to be quite good.Lots better than the stock performance we got from out 5.8 gear.

12 channels but make sure you are on 910.The whole shebang runs on 12 volts. 

Vertical  antenna positioning for distance and horizontal positioning for altitude.

Notice the yellow filter.This,and careful antenna placement and you can get out there a ways on 2.4ghz.(the heat sink on the Vtx is probably unnecessary but I am aiming to put this in the wet, so I sealed it.)

Well,so far I have not been able to adjust any settings on the cam,but hey it's ok.
This cheepy is for poking at the clouds.I have a S.C.2000 $50 cam but I wanted to see what happens with this one first.

A PAL camera? I am far from a expert on the subject but on this side of the pond we operate NTSC, so not really sure how your video quality is....well THAT good as there may be some compatibility/decoding issues at play. Not clear as to how all that works so will defer to "those in the know". The distortion lines running horizontal look like what I used to get running both vtx and motor off one lipo, two battery setup fixed that....you running separate lipos (course not alot of room on that little popwing)? I will be making move to 900mhz here soon, once bank account gets pasted the Christmas hangover.

Oops. You are right!That was a typo.The camera is NTSC.
Yeah the lines are a lil bothersome so I ordered one this. http://www.hobbyking.com/hobbyking/store/__26246__L_C_Power_Filter_for_FPV_A_V_Systems.htm

I don't understand how tx is 12 channels, but you said, " make sure you are on 910."
How do I make sure I'm on 910? Great footage, Thanks

Sorry if I was unclear gadget.You must only fly on 910mhz as,to my knowledge,this is the only channel in the 900mhz band that can be used by the public.In my case my vtx is on ch 1 and my vrx happens to pick up ch1 on ch3...I know.I figure as long as I am broadcasting on 910mgz I can receive on whatever channel corosponds. Point is,make sure you are only on 910mhz. Its good for everybody.
