About the rx shielding - i did it before reading your post and off course wasn't working . I am a little puzzled , shouldn't the antenna filters take care of the radio noise and the ferites of the electrical one ?
A little question for you - i was careless and one of my props killed one of your antennas . I have the connector with some 5cm of coaxial and want to solder a wire to make a secondary antenna (the one on the bottom of the plane, no top performance needed ) . My guess is about 34 cm from coax end but you must know better .

Thank you all for explaining how to get my RF LED to light up.
Thomas, that shure is a nice logo you've got there, now there is no question what we are talking about.
Best regards Poul

Ahernar please look here:
then it should be easy to make a new antenna,
the MCX connector and 50 ohm coax cable is fairly standard, and available worldwide,
I have seen several connectors and wires on ebay for cheaps :-)

Yes I know the page (and I have another two mcx antennas from my other unused receiver - no need to build another ), With the 34cm wire attached to the rest of the coax cable i have something like 80% performance versus your antenna - it's good enough for me . With this plane i will stay inside 3km , and go futher when i will build another one , designed for LR from start .
I must underline , the unique boost function of your transmitter is a very useful thing to have , one of the best safety features I know of .You can count one plane saved by it.

I didnt take pictures but next time I fly I'll try to take some or make a video of it Ill send them to you.
My buddies thought it was very cool 2 of them ordered easystars and will most likely buy FPV gear for them soon, I told them the most important piece of equipment after the FPV gear itself is a long range control system and with that 2+ miles flight from inside the house they really believe it lol.
I've been flying a lot lately, when I get some more time I'll edit some videos, I did some formation flying with my easystar equipped with your LRS and one of my friends full scale cessna 150 lol it was totally awesome, I'll edit it soon and will email it to you. Some people might get offended if I post my recent videos here haha

thomas the RSSI connector on the receiver channel 12 I assume i use the fourth pin and ground and hook that to the IFOSD?
Pratorina, very cool video and all on one battery ;-)
I'm just pullin your leg

I have a really stupid question.
If I wanted to buy the option below from thomasscherrer, what else what I need to buy in order to have a full functioning FPV system assuming I already have a camera, goggles, and RTF plane? What kind of radio would I need to use the below setup?
370 us $ for a starter set 1 LR contain of:
1 x Transmitter, with switchmode 6-20V input range
1 x LR Receiver, 12ch servo outputs
2 x wire antennas with MXC connectors, for 1 receiver
1 x whip antenna with BNC for TX
As you can tell, I am a noob to FPV.

Is it possible to desable the fail-safe of your receiver?
I want to configure the autopilot of the RVOSD and if the fail-safe activates when you swich off the transmitter it doesn't allow to work the autopilot of the RVOSD.
Sorry if it's explained yet ... and sorry for my english

>thomas the RSSI connector on the receiver channel 12

YES, and please to be sure you dont load the receiver too much, please put a 100k resistor in series with the rssi out, use the bargraph function and calibrate each bar,
please inform other users your cal levels, I have seen others requesting this.
>What kind of radio would I need to use the below setup?
wow, that is like asking what kind of car do I need to drive me to work..
we need to ask 100 questions more to be able to give advises here,
if you ask me personally I would go for the Multiplex Royal Evo 9 or 12
look in this thread, this topic have been up 30 times before :-)
as Ahernar says most likely any RC unit you can find will output normal PPM
student pulses in its trainer connector, so in that case it should be compatible.
>Is it possible to desable the fail-safe of your receiver?
you dont need to disable it, and you for sure dont want to !
you simply store the failsave with autopilot activated on the switch on your RC unit,
now it will automaticly be turned on in case of a failsafe.
that is the way the system is intended to be used with any autopilot OSD

great, we could work together, you show and advice people to purchase my LRS
and I give you rebates on your next order :-)

I think not at all, as long as you have an agreement with the fullscale pilot
about what you do and he is a part of all details in the planning,
and he have a good idea about the risk in case something go not as planned,
and you do this a place where no peoples lifes or property is in any danger,
I am only looking so much forward to see the videos.
you are also welcome to send me a secret vimeo link first,
and I will be happy to give you my comments before you make it puplic.
I personally take risks sometimes, if the experiance is worth die for, and the chance
of a fatal is small I am most likely up for it, I have thrown my selv out of planes,
and dived inside homemade submarines, and fired homemade rockets in 1500kg thrust size, other people climb large mountains for the thrill of it, and not all come down again alive, that is perfectly accepted as a thrill vs risk factor. there is no fun for me to look at TV, and that can be quite dangerous too :-) look in the statistics, I hear many of the new flatscreens fall of the wall and kill kids, I think it is really bad to look at TV, not worth the risk vs thril factor.

"....RVOSD will try to detect servo pulses on the inputs, up to the seventh second after being turned on. If it detects no valid pulses, then servo pass thru is disabled and RC Link lost indication (Failsafe or autopilot) display is also disabled.
Up to the seventh second, RVOSD will look for:
In RVOSD PPM mode the OSD will look for pulses in Auxiliary input."
Is there any way to set the RVOSD in autopilot mode without swiching off the transmitter?
The auxiliar channel alows me to get into the RVOSD menú, change screens, etc, but no more...
May be i drown in a glass of water

I still don't get how your system works though. Does the tx plug into the trainer port on your radio? Or do you actually have to take you radio apart to install it? Does your 12channel rx elliminate the need for your original receiver? Say if I wanted to use a Spektrum AR7000 receiver with my DX7 radio. If I wanted to install your tx on my radio, would I still use the AR7000 receiver, or would I just use your 12channel receiver? Or both?
Really sorry for all the stupid questions.
