Thanks Higgy!
You have brought up an important safety issue...

Controlled airspace starts at 18000' overhead the USA, even lower near airports with control towers and/or instrument approachs....

We have another name for that place...
Jethroplex, Masterbase, or the Death Star.

All our full scale training is done just SSW of the terminal by 3 miles.
My sincere sympathies on passing thru!...

OSD needs a valid video image for overlay. If no video input, one gets a blank screen on output.
Does the camera send out video? ie conect to a video monitor and see if camera is 100%.

To further Ommandawn's comments...

All computations: Ground Speed, Distance to Waypoint, LOS, angle to aircraft, compass heading (actually it's really GPS track), etc derive their data from the...

Probably burned a copper/solder trace or filtering inductor in the 12V line on the OSD. I don't have a schematic or block diagram of the current version.
What version was it?
I believe the older...

Winds inside/around a thunderstorm (updrafts/downdrafts) may be more powerful then the thrust available to counteract the performance gains/losses. Is there enough thrust to counter the amount of...

Does your plastic servo wire ends have little tabs on them? I've run across servos with these tabs and had to do the following....
Lightly sand them off to make the pin housings thinner in order not...

What antenna is on the video TXR? Is it wide and with a yellow stripe near the tip?
Similar to this: http://www.dpcav.com/xcart/900MHz-Antenna-Compact-Dipole.html

Or is it the skinney one like:...

Nice bright colored yaw string! :D
Great work!

What antenna?
I suspect a Yagi beam or patch antenna of substantial gain on both ends at a minimum.
Remember, FPV is done line of sight normally, not through houses (filled with metal stoves,...

WD40 was the 40th attempt by chemist Norm Larsen, back in 1953.
WD stands for Water Displacement, and it was his 40th formula that
worked.

Despite what people think it's used for, lubercation,...

Your parts may be sitting collecting dust for some time... not yet available for sale. :confused:

What you need to know is there are two (yes 2, individuals that ARE Range Video). One in Miami, FL and the other in the Dominican Republic.
One does software development AND testing of said...

Can I have my AOA gauge like on my B737-800? :D

Here's a shot thru my HUD on final for 17L at KDFW, the AOA gauge is in upper right, showing a value of 4.2

We are trained too fly without the...

Range Video used to sell a video switch, but I just looked and it's no longer available. I use two board cameras from China with no issues in signal noise.

Battery voltage is self explainatory...I hope! Configurable in the setup menu.

Current is live data (as is the battery voltage), it's a real time measurement of how many amperes you are pulling...

Vne is actually Vnever exceed, i.e. redline. Wings don't come off unless one pulls or pushes on the stick to the stop, and that happens at a much lower speed! :) Typically on small light aircraft...

No two models are alike, these are individually hand built, batteries & electronics strewn about the airframe. How can Vne be determined? One model with lots of slop in the ailerons/flaperons to...

A question comes to mind... just where is the RFI being introduced?
If it's the GPS receiver (i.e. antenna) then it will be distance (separation) between the GPS unit and other RFI emitters such as...

Obtain some servo cables and grab your soldering iron, solder, and heat shrink tubing!
i.e. Build the required adapter cables from parts lying around. :D

increasing the gain of the RC transmitter antenna and/or the amplifier you posted above will help.
Antenna orientation on the aircraft is important... you don't want the video TXR antenna beaming RF...

ERP=Effective Radiated Power It's a standardized theoretical measurement of radio frequency (RF) energy
Where one takes the :
(Output power) X (antenna gain/loss - feedline losses)=ERP

Antenna...

Get some separation (distance) between the FrSky Receive antenna and the Video transmit antenna.
Placing a 800mW 1.3GHz Video TXR right next to a sensitive 2.4GHz RXR will overload (swamp) the...

Could be the static port is in a location of slightly lower than 'real' static pressure... inside fuselage where typically the pressure is lower due locally higher velocity air flowingover gaps...
