Rangevideo has just released their first OSD-solution.

This one looks really good - with autopilot as well.

I think this will be a hard competitor for the Dragon OSD!

Very cool looking. ElCheapo, the designer of it, has certainly covered all the desirable FPV features. If the low price is coupled with good customer support, then it will be another killer FPV solution.

Two years ago the FPV OSD market was non-existent. There will soon be perhaps a half-dozen different designs available for sale. My oh my, things have dramatically changed!

I've had no problems dealing with Rangevideo but I have seen a lot of people complain about a lack of response from Vova on orders etc. However, anytime I've ordered stuff I've gotten it in two or three days. I haven't run into any support issues though, so I can't speak on his response from that aspect.

Dose that mean OSD prices will fall ??? ;)

eickst: I would have said the same as you a month ago. Sorry to say I don't have that opinion anymore. I ordered a pan/tilt kit for my TSII which I've been waiting for allmost 3.5 weeks. Still haven't got it, and vova doesn't respond. I guess it will be worse after the release of this OSD.

Terry: The number of commercial OSD-solutions has exploded the last few years, so yes, I'll guess the prices will fall.

This one is only $300 with 5-Hz GPS, so that sounds like a low cost deal to me.

Want it cheaper? Well, the OSD option from Eagle Tree will be $45. It uses the MAXIM OSD chip, which is a nice component (sort of like a modernized STV5730). They mentioned earlier this year that the software interface will be made public so that the OSD can be used by hobbyists for other things. If they follow through, then you could use their OSD board along with your own custom hardware to make something cool. Or, if you already have the Eagle Tree telemetry system, then you already there. :)

What is critical for these products to succeed is top notch customer support. OSD's often require more handholding than the usual R/C FPV products.

Agree specially at those first moments such as beta testing stages. Once the product is well known by users, this comes down quickly. I think that an OSD is a device for advanced users, to do in sight flights I think it´s not necessary.

Regarding what you told before about the really fast evolution for this gadgets it´s surprising how these companies with new products grow. For sure nowadays there is a big market, enough to have all those dealers existing, but I do think too that perhaps there is no longer room for all, we´ll see, comunication with customers would be a must for the survivors.

Traditional r/c dealers, and manufactures seem don´t enter in this market, too bad for them if this modality tends like today growing, they would need to adapt to the market´s changes, this is a gold rule in business

Very tempting!

The screen displays look dynamite!

Still, alot of unanswered questions.

There is no picture of the OSD and even the actual weight and dimensions are undecided.

The specs put the autopilot and return to home on the same line, raising the question can it actually follow waypoints or is it just a failsafe feature.

The specs show a vario function, would that be from gps altitude alone? Most are not accurate enough to do that.

There seems to be an arificial horizon, how is that supposed to work without IR sensors or an IMU? In theory bank angle can be calculated knowing speed and turn radius but I've never seen it done for an artificial horizon.

Will there be options for sensors, IMU, data logging, Google Earth mapping and waypoints?

It does look promising, and the price is right.

It's not an AHI, but the "home pointer".

The dimensions of the board is 9x5cm - weight is still unknown.

Vova says the board will have full waypoint capabilities before the end of july.

The variometer is only based on GPS readings. A GPS is pretty accurate on relative vertical movement, but not absolute.

As said, there is no AHI. Optional sensors has not been announced, and will most probably never be.

Well, I put one on order. What the heck? I love my Inspire but it's too big for the Easy Star. This should work out pretty cool, I hope. I'll have to waite to try it out though, I'm out of country for a few more months.

Hi guys,

Im new to all of this...and would just to make sure about something. If I want to put a video cam on my plane, all I would need is this kit:

http://rangevideo.com/index.php?main_page=...;products_id=98

Is that correct? I dont see it coming with a battery so probably haveto add that myself, but is that all? I have a JR 2.4GHZ radio...should be compatible, right?

I see the 2.4ghz system with 1000mW is not compatible with 2.4ghz radios? Is that just because of the same frequency being used to fly the plane? Which will have greater range?

Thanks for any advice,

Bye

apcoza the kit your talking about will work fine. For most of the fpv'rs here they generally add an extra battery to power the onboard tx and camera although you can use the voltage step down from rangevideo to power your video system off your battery. Which is what I've been doing for my one plane. Works fine.

http://www.rangevideo.com/index.php?main_p...5d87080667642d4

If you've already got the 2.4ghz system your in the same boat although from what I've been reading the futaba 9c 72mhz radio system seems to be the best for long distance. But it's still a good starting point as you won't have to worry about glitching. I would personally get the .5watt system, little lighter, less power consumption, doesn't get as hot as the 1w and works just as well for the range your expecting with your remote, also look at "goof proof" antenna for the receiver. It's a do it yourself antenna care o rc-cam.com.

Hi Ivan,

Thanks for the quick reply. Yes that adapter would make sense! Thanks for the tip. Yes I think ill order the 500mW system, I would eventually want longer range but if my limit right now is my radio, no point in going overboard on range, ill just be able to watch it fly to its death :)

Are there products to boost radio reception too?

Cant wait to get this setup and fly my plane around the neighbourhood :D

Boost reception of which, the receiver in the airplane or the video receiver? Video receiver just needs a better antenna(your ground station). As for receiver on airplane, sometimes you can change antenna but for the 2.4ghz I don't think there are too many out there yet(or if possible, not possible so far with spektrum receivers or I haven't come across it yet). When I was researching on how to increase airplane control range it came down to changing antenna on the remote to 5-6dbi from the 3 dbi and adding an amp to the signal. Neither of which I have done, still contemplating on just getting an extra futaba radio so I can get the headtracker function and longer range, seems to be more mods and the lower the frequency seems to actually increase the range. Although someone just figured out a way to get the headtracker function to work with spektrum dx7 so still thinking which way to go.

Ivan.

I mean increase the range on the radio itself, in my case the JR 2610...hmm ok Ill look around and see what people are doing. Long range is what I want ;)

Oops ! I dont have a 2.4GHZ radio...i dont know what mine is...its a JR 2610..System should still work though, rigth? The 900mhz 500mw kit?

the video stuff will work fine, if your radio isn't 2.4ghz then more than likely it's 72mhz then.

There are 2.4ghz transmitter modules available for certain JR transmitters...

Thanks Ill have a look. Is there any recommended receiver for the plane for longish range? I've ordered the range video kit, but in the meantime want to get an electric glider for flight duration. Any suggestions or tips welcome!

Thanks

I think most JR receivers are single conversion but I've never heard any problems with range. Mine is much farther than I can see the plane however I have no Idea what the max range is. I'm on 72 and know when the band conditions are right the range can be in the thousands of miles (not too helpful though. Just to give an idea of how the sig can be affected). A mmic could be used as an RF amp for the Rx with a little construction time....

Hi,

Well my plan is to just use longer antennas...I live on top of a hill and have clear line of sight for quite some distance...just a few trees on the one side im worried will cause a problem...so What about a long aerial on the roof? I will only fly from the roof so dont need it to be portable..I saw the patch antenna from Rangevideo I might get for the rc cam, but for the radio control Might be able to just use a long aerial from a radioshack shop? Or am I way off here? If you have straight line of sight, at what est. distance should you lose control of the plane? With a standard JR 2610 radio?

It sure does sound like you have a great place to take off from... The trees won't bother you unless of course, you let them get between you and the plane. Then the signal from the plane will be absorbed by the trees and vice versa. Long pieces of wire for the Rx are fine but if used for the Tx you will have a problem. The Tx has to be matched reasonably well to the antenna or you'll have standing waves that will be reflected back to the Tx and will probably cause it to heat up and kill it. I don't think any of these transmitter modules have any sort of protection against high SWR (Standing Wave Reflection).

Can't give an estimate of distance. If the JR is on the 72mhz band, you will lose your video before you lose control of the plane given that your video Tx works on a frequency above 1ghc. There are too many variables such as humidity, rain, the sun, possible multipathing, power output of Tx, etc. A FPV won't be of any use at that point. The only thing that could save the plane would be an automatic GPS based system to return to home on signal (72mhz) loss. Some Amateur Radio Operators in Georgia have gotten over 30 mile point to point (mountain top) ranges on wifi equipment without modification to the units except for antennas. I would imagine they used parabolic dishes as the wifi signal is in the 2.4 ghc band also.

.

I think I might just go into the antenna building/selling business. I've never understood why a patch antenna should cost as much as they do. I think half of what they are selling for or even a little less would be a fair price. The profit most certainly is a few hundred percent.

I hope this helps you understand some of the basics that pertain to radio frequencies, specificaly 2.4ghc. Good luch with your project. It most certainly rewarding when you can see it working.....
