RE: Some of my FPV videos
Haven't seen too much activity on thi thread, guess i could put up the latest and greatest so far. Finally found a decent antenna combination to make sure i don't lose video for quite a way out - SPW and Crosshair on 1.28 Ghz 800 Mw setup.

RE: World records and FPV?
I saw the list of categories and wonder if this would apply to an organization rather than one individual especially with the distances that they cover with each milestone. Could make a mention on a posting and see if there is any takers for the U-1.a.2 class, there might be a slight interest. Otherwise, they're just fpv addicts like myself and do this just to fuel the addiction. At the very least, the OSD telemetry would have to be verified by the FAI governing body before they would consider any attempts under their listed categories for making the record attempts. The other item that comes to mind, when coming to FPV and the AMA is the conflict of rules in regards to line of sight limitations, which most of the pilots are flying well outside the boundaries of unless they have the chase team in place. I personally would like to see some of those names filling some of the records, especially for bragging rights after what some of them had to endure. 5.5 hours trying to fly thermals out to the 100Km mark and back required bathroom breaks and the use of a copilot.

RE: LawMate 1W transmitter - How to power this?
Hope you went to fpvlabs for the answer by now. Usually a 3S lipo will work just fine, the lawmate should come with it's own heatsink to protect it from the heat.

RE: Anyone have problems with FPV's equipment?
Have been running a few tests to see if i could get the failsafe to activate and had some interesting results running the system on the team losi truck. The range and video reception are definitely affected as you operate close to the ground. Took the truck out to a park with some trails that placed a few obstacles in the line of sight, and did affect the video to some extent but still useable. Was able to get better reception when using the 3Dbi standard antenna on the Tx that was originally intended for the Rx, while using the 8Dbi on the Rx. The tuned V antenna does work really well in the air but too much interference closer to the ground. The Frsky worked really well during this portion of the ground test with no glitches what so ever. With this test it was only around 100 ft out with plenty of wireless networks around the area with the metal structure blocking a good portion of the course. The second portion of the test was going out to the field which tested overall range and was very surprised with the results. The video held up very well but the range was greatly affected, don't know if the reinforced taxiway might have something to do with that. As for Tx frequencies, tried ch 18 at first on the standard fm and was only able to go out around 75 yards. Changed back over to the Frsky with the 7Dbi antenna on the Tx and the range went out to 100 yds before the failsafe kicked in, really surprising since this is line of sight, no obstructions. Had one other try by using a 9Dbi stacked element antenna (15") for networks and was able to push the range out another 50 yds approx. Really curious if the additional amplifier module for the Tx module will get it out to around 2-300 yds for ground range considering the stated range for the air in that configuration is just over 6 miles. One other item i'm considering purchasing is the lo pass filter for the video Tx just in case this is what might have caused the signal loss/interference. The replacement plane is all set up to get the gear installed but wanting to make absolutely it won't cause this one to go in.

RE: Anyone have problems with FPV's equipment?
Very busy over the last 10 days since the last post. In short, the video was awesome with the new camera for about 8 minutes. I had also put in about 4 hours total flight time with the Frsky set up with no problems until the day of the flight with the new camera. Don't know what caused the receiver to go into failsafe but it was set for a slow left roll with almost full throttle, and all it took was 3 seconds before it came back but that was 1/2 second before impacting in to a field of soft dirt which am thankful to which was what saved all the equipment except the camera pan n tilt servos. The video tx and camera had their plugs pop off upon impact and didn't have to worry about the tx burning up. The grass around the crash site was around 2 ft tall and took around 45 minutes to find the impact. When an old timer style aircraft crashes like this, usually all thats left is a big mess of balsa sticks and ripped fabric. The recorded video was the last thing i was looking at before the crash. Tried publishing on the rcu videos but they posted they were full and no uploads, need to look for another site. Had some great views from around 400 ft up and quite a ways out, atleast i couldn't hear the 4 cycle sound when flying around. Got everything sorted out and verified the vid system still works but the 2.4 receiver was missing an antenna, assuming it came off in the crash and can not get a replacement for this and Rangevideo offered me another Rx for half price. Did a preliminary test flight with one of the light foamy club pylon racer with good results. Already have another plane ready to start integrating the system installed in the wing which required new covering anyway. Still running tests to verify that the area where the failsafe locked in wasn't the overall cause considering the plane was only 300 ft out and 100 ft up. Running some additional ground tests next on the Team Losi xxt truck down the 2500 ft runway with the vid and frsky together to make an overall determination there won't be any further issues, atleast as far as operations close to the ground is concerned. Don't need to lose another plane to radio problems but it is one way to shrink down the amount of planes in the inventory, got too many anyways.

RE: Anyone have problems with FPV's equipment?
Just called home from work to find out the camera just arrived a day early and going to get it mounted tonight. Fabricating a BNC to RCA adapter plug with spare parts lying around the parts bins. I'm kinda expecting good results from this camera after looking at the reviews and some of the videos published showing the day to night mode, will probably make good use of this function in the future. The other incorporation that I wanted to try to attempt is the portable gps receiver antenna that attaches to the HP Ipaq. Last night I finally found where the wires for the signal broke off of the plug and had it working great, but need to find out if the signal can be transimitted through the audio port on the Tx and see if the downloaded signal will be of sufficient quality for the Ipaq to interpret on the other end. This will allow the Pocket streets and trips application to present a real time readout next to the video output of the airplane position, direction and altitude as well as using the moving map function to track where the plane is moving. Keeping the fingers crossed on this one, as the only thing that should keep me in check of the distance out untill the purchase of the Headplay goggles and the OSD can be made. With alot of luck I should be back in business for Sundays flying session.

RE: Controller Q's, Joysticks, Range, etc..
Flying with the joystick sounds like a cool idea. Wouldn't mind setting up something like that with an actual seat and monitor arrangement like some of the examples i've seen done with the Xplane or MS Flight sim 10. Would take a little getting used to knowing the plane is still at the mercy of a good signal. Spend some time to fully test any equipment before integrating into the plane. No reason not to test it, try it out on an r/c car if you've got one or similar at first. Worked out the bugs on mine that way and gave my son a workout by chasing him around the outside of the house while I was using a monitor in a closed garage. As for the electronics design, quite excellent if you have a decent background in how to put together a system that works in all the details you're discussing previously, you might have a viable product down the line that might spark some interest in other fpv'ers. Keep the ideas alive, always room for innovation...

RE: Controller Q's, Joysticks, Range, etc..
You're absolutely welcome. Just going into the subject from what i've seen alot of other people in your position, try to start with something way over the experience level and end up wasting alot of money. The sim should definitely get you prepped, just hope the club can help you out. Start slow at first until the confidence kicks in, you'll have a blast when you start doing the aerobatics by yourself. Plus the foamie aircraft are easy to fix in the event of the inevitable crash. It wasn't till about 5 years ago that i started tinkering around with a cheap fpv set up and was looking into what you were describing when i found some schematics for the video transmitter and receiver in a popular mechanics mag. Nowdays the equipment is tried and tested and makes it so easy to get the plane outfitted. Give it some time, you'll be doing touch n goes without even looking at the plane before you know it. I plan on giving my new equipment a full test when i get down to Ca in October, and using a big lofty stable airplane does make it easy to pack in all the gear and still have room throw in more.

RE: Controller Q's, Joysticks, Range, etc..
Quite a list of questions about the subject, many different approaches to getting an airplane flying successfully. Don't know if you live close to where there is a Model r/c club, but that would be my first suggestion and find a person that could get you through the initial difficulties of learning to fly the airplane first. Wouldn't do you any good to do the fpv if the video system fails and your still in the training phase. Getting yourself a slow flying airplane with a big wing would be really beneficial to speeding up the learning curve until you're ready to move up. There is several r/c flight sims available to get you through this if no club is in the local area and for the cost of the sim, will save you twice the cost of replacing/repairing broken airplanes. It also might help you decide which model might be best for carrying the weight of the video equipment. The other major suggestion is to keep it simple, trying to invent the radio controller all over again can get you creative but there is many reliable radios operating on the 2.4Ghz range since they are locked in by dual receivers and encoded to reduce interference to an absolute minimum. The 1W amp supplied for the 2.4Ghz with the right antenna can give up to over 6 miles of range. There is controllers out there that can be applied through the computer but almost way too much hassle. Check out some of the companies that deal in FPV equipment and they've already done the hard work for you, found Rangevideo to have reliable products and the best service but there is many other companies that offer equipment to get you into the next phase of flying through the monitor. All I can say is don't overcomplicate the hobby, it's complicated enough without re-inventing the wheel, especially when most of the electronics sold today are getting cheaper and disposable.

Using the audio line for other uses on fpv.
Don't know if anyone has tried doing this or not, but wanted to do some background check since I don't have an Oscilloscope to evaluate signal quality. I'm wanting to find out if a digital signal from a gps could be sent through the audio line on the fpv transmitter with out too much distortion. The Holux gps module is from an HP Ipaq and is powered from a 12 v source and the two signal lines can be hooked up to the audio in on the Tx but don't know if the Ipaq would have a readable signal coming from the ground based receiver. Hoping to use the moving maps and telemetry from the Pocket Streets and Trips application to show the gps info next to the video display until i can afford to purchase the rvosd later on.

RE: Anyone have problems with FPV's equipment?
So far, Rangevideo products are working as advertised and quite well. Being able to use the old JR system on the 2.4Ghz Frsky appears to be working well with the 7Dbi antenna with great range during the ground check, can get around 200 ft from the plane before losing the signal. The only problem that i've had so far is the camera that was reutilized from the older set up, can't adjust a proper white balance. Turned it down to just before it blanks out and is still overdriving the display, even when placing a darkened lens over the front. Darkens things up a bit and allows the trees and other green to show up but the runway is bright white. That's it - Ordered the KX-191 cam from Rangevideo today and hoping to get some much better results with the automatic tuning between day and night conditions. Hope to post a small vid of the results when installed. The 1.3Ghz tx doesn't even begin to warm up with the 3 cell lipo and the heat sinks mounted, and have been able to receive a very reliable and stable signal with no issues. Hoping the reception is for the distance as specified. The only other parts to be acquired over the next six months are the RVOSD5, 2.4Ghz amp for the JR and Vid goggles. Did take a big notice there hasn't been much activity on this thread, but am thoroughly a big fan of Rangevideo so far.

RE: Anyone have problems with FPV's equipment?
Had some funding available to make the go ahead for purchasing the Frsky 2.4Ghz module($45) for the JR 347 radio thats been sitting on the upper shelf for the better part of the last 4 - 5 years with bad range problems (not a bad deal, got it for free...). As soon as it arrived from Rangevideo as well, screwed on the 7Dbi patch antenna purchased for $15 and ran the binding process with the new receiver and now i've got a new radio to eliminate problem associated on the 72 Mhz band. This new receiver allows the use of Futaba servos. This setup gives up to 4 1/2 Km of range and can be extended further with the amp module that has been available for purchase with a few adapters. All i'm looking for is a rock solid signal when i get down to El Centro in the next couple of months to do some testing around the surrounding hills on the open desert and gives me a chance to do some realistic evaluations of all the equipment.

[:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D][:D] Received all the 1.3Ghz radio package in good order today. Set up the receiver with a good power source, the micro camera from the previous setup has its own 9v battery for power and used a 900Mah 3s lipo for the Tx. Even went the length to mount on the top and bottom some really effective heat sinks and the operation is good to go. The Tx appears to not have the heating problem that the previous Tx's had and this Tx has a good review on it so far. Looking forward to getting the equipment installed on the airplane to try it at the first opportunity. Hope the only problem that comes up is where to get the funding for the rest of the OSD equipment and to not out fly the range of the radio. Thanks Vova!

Got a fresh start by finally placing on order the 1.3Ghz setup from Rangevideo with the high gain antennas, different configuration of Tx but will use some better heat sink materials. Good reviews on this equipment, should arrive by tomorrow and hope to get back in to pattern work. I used the camera from the 2.4 Ghz cam/tx combo and removed the tx board and the cam works like a charm on the monitor, just need to get the rca plugs spliced up and should be ready to test out.

The s/n chosen was the one that already had the pic on the net - 42-38271 since the plane is currently redesignated to 20961. Since there is no past pictures of the WW2 interior, wanted to incorporate much of the current interior unless someone else has some examples of other ww2 era Waco's used during that period, would greatly appreciate any additional assistance.

RE: Anyone have problems with FPV's equipment?
The power supply in use is adjustable for both voltage and the current on small levels. That is where i ran into problems trying to use it since it wouldn't push enough current to even operate either component. True that the Tx that is rated for 500Mw is only supposed to draw the stated amount, regardless of the capacity of the battery or source. Didn't seem so in this case, my meter measures the current in tenths of an amp and the time to plug in to the Tx and get a reading didn't seem to give a reliable reading. Either way, it heated up the 700Mah 3 cell fairly fast, shouldn't have unless its also driving a speed control with motor. The video out put was not a factor but could use a smaller camera since the plane has enough issues trying to stay on track when taking off. The choice of Tx and Rx was the 1.3ghz 500Mw to help eliminate the interference from all the wireless routers set up as was the problem with the low power 2.4 ghz system from Z hobby. Used this system reliably for 3 years before the Rx quit working and lack a decent o'scope to trace where the video signal went dead. Was able to get enough distance (400ft) out of it to set the plane up for doing basic pattern work for touch n go's. All that Tx/ cam unit required was a 9V battery and lasted about a month of flying. Did take a look at the ready made r/c, good viable source to look at when i get back from the next work assignment. One example of turning the current up, I worked in a 2M shop where the prc 2000 solder station has a thermal tip handle for burning insulation off of wires or reflowing circuit cards, where the current is the controlling factor. the voltage stays the same but attach a 16 gauge piece of wire about 2" in length in the holders and about half way through the setting would turn the wire into a light element, didn't know it would be so amusing for the new techs in the shop..

[quote]ORIGINAL: katarinaconnors When you say the tx is using all the power .... What else are you hooking to it?? For a comple system using a eflite 370 and speed controller, radio ect.. I use a 2200 3 cell pack. .?? 15 minute flights at least... Start small,hook up cam, Tx and look at your video.... The first and only TX I ever burned up was when using a wall 12 volt supply. [/quote] When i first tried using the Tx, the 700mah 3 cell lipo was the only power source with the jvc camera hooked up to the supplied video/audio cables, after about 5 minutes the tx was running fairly hot even with the fan blowing over it, continued to run video tests up until 15 minutes when the Tx went cold. The video was coming through to the receiver but had to use a lipo on it as i found out the regulated power supply of 12v@500Mah (checked with the current meter side of the dmm) caused a horizontally split screen and needed more than 500Mah to operate properly, no problems since then (1500Mah lipo). This was the first Tx before sending it in to have a replacement and upon receiving the second, attempted to use the lower mah rating of the regulated power supply to match the power rating of the tx. That barely had enough power to put a video output signal and slowly increased the current adjustment up while observing the output on the screen to no avail since it had maxed out. The Tx was getting warmed up just a little bit, decided to try using the 700Mah lipo for short increments of 30 seconds and was having better luck but the Tx would heat up almost immediately. About the fifth time through the Tx would'nt even warm up and determined it went dead just like the last one. Hobby wireless stopped responding with the emails after that and have been stuck with the dead equipment since then. Next time shopping for a reliable Tx, i'll probably try rangevideo 500mw. At $50 per Tx, expensive for a single attempt to watch them burn up, but they shouldn't quit working after such a short time.

RE: Anyone have problems with FPV's equipment?
[quote]ORIGINAL: katarinaconnors Jetjocky69 is right capacity of the battery has nothing to do with it as almost any decent lipo of 800 mah is more than enough. Just take the total current draw of the tx and camera and divide that into the capacity of the battery.. I.e. Tx 200, camera 100= 300, into 1000(the battery) gives you three hours..in theory. Two cautions however, is that you only want to draw about 70 % from your battery, and battery mfgrs. Lie... Also if you forget and don't unplug it you will ruin your Lipo.. Easiest way is again, go with 12 volt equipment, use a 3 cell ..Lipo.. For everything, Or use BECs you get your required voltage. Even a 1watt tx is not going to eat much from a pack given your speed controller is pulling at least twenty times that.. In fact most ESC idle more than a TX.. pulls. This way you ESC will be beeping at you and you won't forget to unplug.. P.s. Guys most of this stuff requires a ham license! So hopefully you know amps, ohms and volts and how they relate... But I won't tell... Lol [/quote] When I was first running the tx, the power was supplied from a regulated power supply (12v @500MaH) with no video output, the trouble happened after 30 seconds of using the 700Mah 3cell lipo with good video. What it looked like was happening is the 500 Mw Tx was trying to use all the current available from lipo and requires the use of a voltage/current regulator external to the Tx. Even with cooling airflow over the Tx didn't stop the thermal runaway. The budget is still limited and have to purchase a piece at a time. Atleast the airplane is flight tested with the JVC cam.

RE: Anyone have problems with FPV's equipment?
Thanks for the interest in the discussion with the problems with the video equipment. One of the main concerns i had when i first received the tx/rx from Hobbywireless was how well the equipment was to set up and use right away, unfortunately when i operated the receiver for the first time it was just under the current required and caused the screen to split horizontally through the middle. As for the Tx, i first used a 700mah lipo which had 12 v measured which did give the display on the monitor for the ten minutes that i had operated for, then on the second attempt it would not even turn on like it had overheated and burned out. The second Tx sent as a replacement was operated at a much lower mah rating and would turn on but no video until it was turned up in small increment, and was only visible for the first second after applying power. Just when i thought the current and voltage were just where they needed to be, the Tx stopped operating just like the first one. When i stopped getting responses from Hobbywireless, i tried to contact the other companies to no avail. Have given up trying to get a working system for now and may purchase another cheap set up through z hobby again with the 9 v tx system with the 400 ft range. Atleast it was good for doing touch n goes through the monitor. I will need to get ahold of one of the voltage regulators for the tx next time.

RE: Anyone have problems with FPV's equipment?
I don't appear to have any problem with the video signal from the camera since i use it with the tv all the time. Was using it to capture video when hooked up to the receiver on the z hobby setup and what i was using to fly under the camera using the viewer screen with about 2.5 hours flying logged before the receiver took a dump and quit working. The transmitter seemed to be a bit trickier, there was about a 1/10 of a second where i could see a flash of video when i plugged in the power before it went back to static, and this was using the 500 MaH rated output. Did try a 700MaH lipo that had 11.5v and this is where it heated up really fast and quit working after just a few minutes on the first transmitter, but i had video during that time. The second transmitter still did have the heating issues and quit working after about the 5th time plugging in the power, really kept a close eye on the current output using a digital current meter. I sent emails to rangevideo for some advice and their suggestion is to purchase one of their transmitters as they won't work with equipment from another video supplier such as Hobbywireless, understandable but had to ask since Hobbywireless got tired of answering my emails.

RE: Anyone have problems with FPV's equipment?
Wing it, thanks for sharing the info about the set up and experiences. Turns out that the receiver problem seems to come about when the required Mah rating is just below the threshold and by using a 12 volt gel cell appeared to eliminate the double split screen. As for the Transmitter, it seems to be giving me more grief than it's worth and Hobbywireless didn't like sending gear back and forth if it doesn't solve the problem. Recently I tried to provide a more regulated voltage to the new transmitter to control the amount of heat generated but wasn't getting any video on the monitor. Had a fan blowing over the unit the entire time. The transmitter appeared to be getting a signal out as the voltage and current were adjusted but still no video from the camera, eventually the transmitter went dead and the voltage input was no higher than 12.5v. The recommended current rating stated 500 MaH and didn't want to go anywhere over it but still managed to kill the transmitter anyway. Am I just having a bad run of equipment from Hobbywireless? When i purchased the Z-hobby setup, the 9v camera/transmitter didn't give one ounce of grief and would give a fairly reliable view to about 400 ft up or untill the plane came too close to someones wireless network operating on a freq too close to mine. If i ever decide to give the 900Mhz set another try, will have to go with Rangevideo and purchase a voltage regulator to see if the results are any better. The camcorder would have the zoom function adjustable from the radio. Oh well, the funds are going in to fix my truck for now.

AH-64, there doesn't appear to be any problem with the transmitted signal. The display coming from the receiver is split horizontally regardless of a received signal or just displaying static. I am tempted to open it up and find if there is any sync adjustments that can be made.
