Panasonic CCD Video
There was heavy turbulence at the park, so I couldn’t get a close-up video of the A-7 and tank. At the airport a full-scale was taxiing in and made a good subject for a few minutes.
The video was taken at sunset so the lighting is poor, but the camera held up well in the conditions. I’ll try to post something from a brighter day when I get a chance.

Thanks Chuck!

Extremely clear image. I dont know how you manage to eliminate all the vibrations like you do. You need to repost the specs for your video stick again for those of us too lazy to search thru the threads. Like me.
Pic of how you mounted the camera would help too. I have NO luck with mounting em on IC planes for some reason.
Wonder what was goin thru that pilot's mind when you flew over...

He didn’t see me coming, I dove in from the sun!

Actually, he’s a fellow RC flyer (I know him well) and came over after parking his plane to watch the live video while I flew another flight. He has the white pickup that was by my red car in one of the low passes.

Vibration isn’t fun and I wish I had a secret fix all I could share. But I’ve found the best system to be a soft mounted engine and a rigid mounted camera. Right now the plane has no vibration at any throttle position and I love it! Well see what happens when I hook up the tilt servo.

I’ll post a few pictures of the new camera mount, but not much has changed from the original design.

I torn my video sender out of the wing in anticipation of ordering a second 600mW system from Bill, but when I had saved enough and went to his site he was sold out! Drat, NO it can’t be! So I just put everything back as it was, until later this month anyway.

Hacked wireless video senders can be a lot of fun and a great source of RF project experience. For sure, it's amazing what 1mW of RF can do with a careful installation and good antenna system.

Status: offline 		WOW, awesome quality!!! Which TX/RX are you using for your video equipment and what plane was that in? BTW, great take off and landing on your very short strip, you should be good for landing on a carrier

I finally got my Flyin King in the air last night with the digital Canon A70 but for some reason I only got 1 second of footage

You read my mind!

I’m going to use a dual camera system on my new plane, but if I get a chance I’ll try to mount a second on the video stick and get some footage.

I can still remember a quote from you about 9 months ago and it went something like this, “when I added a 50mW amp to my sender it really brought it to life!”
That statement has been killing me ever since!
I love the no compromises quality I get with the setup but I want more power! I wish I had your electronic ability, but all the pictures of amps being added to systems looked a little different than mine. I figured I would just ruin it trying the mod.
If this thing put out 50 to 200mW I would be a very happy camper!

P.S. the video I posted in this link was done with a stock receiver and it’s stock patch antenna (I have 2 of the systems). I wasn’t in the mood to bring out my big antenna and didn’t plan on flying beyond visual anyway.


Ensignnolo, jester125, Skycam41,
Thanks!
I’ll try to post some detail on the installation and equipment as soon as I can.
I’m on a dial-up at the moment so it’s a little harder to send pictures and video these days. But I did find some space on my ISP’s FTP site, so I can post some videos from time to time.

The transmitter is a Part-15 Radio Shack video sender that is long out of production.
I modified it by installing an antenna from a computer wireless network access point.

Status: offline 		I think you will be blown away by the 50mW upgrade. Perhaps you will get the courage to add the Linx BBA-519 Amp by looking at these photos of Xcam2 hacks (it is all the same to the Linx):
http://groups.msn.com/rccam/rccam4.msnw?action=ShowPhoto&PhotoID=20
http://www.yb2normal.com/linxamp.html

Basically there is an RF input, an RF output, +5VDC power, and a bunch of grounds (everyone of them count too). To prevent wayward oscillations, the amp must be installed so that the ground pins are well coupled to the Tx's PCB ground (short leads!). Operation on voltages higher than 5V is possible if you follow the data sheet's current limiting resistor info. Success is easy if you keep all the leads short and follow basic RF construction. The photos show typical methods that the average mortal can do.

Is the correct one to order $13.95? I could give it a try on my second sender, if you are willing to look at some close-up pictures to make sure I'm using the proper pads and pins?
I have a feeling I need to remove the RF module from the circuit board to see anything that looks like the links you gave me.

Is the backing circuit board needed at all, or just the TX section?
It looks like a fun project.

It is $15.00 from Digi-Key: http://dkc3.digikey.com/PDF/T041/0521.pdf

Do not do that (leave the sardine can alone). All you need is access to the Tx's antenna connection (where the coax solders to the PCB). Remove the antenna coax, and using a VERY short wire (mine was about 0.2" long), connect the BBA-519's input to it. The antenna coax will go to the BBA-519's RF output. All Linx grounds go to the Tx's RF ground, which is essentially the massive copper copper plane on the Tx's PCB. Do not skimp on the RF gnds!

I installed mine "deadbug" style, per the photo shown in the link I posted. Yb2normal did the opposite. Use whatever method is easiest for you to use. The goal is to install the RF Amp with VERY short leads. At microwave frequencies, the wires become efficient inductors and really mess things up.

Status: offline 		I’m pretty sure my antenna wire goes under "then into" the can and over the base circuit board. I’m not sure I can get at it with out removing the can, I’ll take come pictures tonight of the top and bottom and post them.

BTW, I did a short day flight today and it looked very nice and bright, I’ll try to make a short 10 second or so video from the footage and post it tomorrow.

Status: offline 		Here are some pictures of the installation, and one of the video senders.

I'm going to switch to a BlackWidowAV system soon. But I would like to try the 50mW hack just for the fun of it Mr. RC-CAM, I can always use the system somewhere.

For the camera mount, I put a support area in the wing and ran a servo lead and the camera wires to it. That way I can try out new mounts by just making a new hatch and screwing it down.
If you look close at the side of the plane you can see it looks like a pincushion! I've tried a lot of different camera mounts.

Here is a short low quality video using the old CMOS cam, with a Pan-Tilt mount.
The Pan-Tilt setup was fun, but with no assisted flight devices like a Co-Pilot on the plane I found it was just easier to use tilt only and fly the plane at what I want to look at.
The Pan-Tilt setup was removed and will go on the next plane I’m building, it will have flight assists that will fly the plane while I look around.

Pan-Tilt.zip (1.7 megs)


There are more details about the plane and the Pan-Tilt mount at my site, but these pictures are the latest configuration until the Black Widow system arrives!
