best OSD with most features for the money? OSD product matrix here..

I've been digging around at the idea of going with an OSD for my future Rangevideo 900mhz 500mw (kx191) setup? (btw, is the kx191 an ok camera, can it even be used in the dark fairly well)?


From everything i've read on here and the net, here seem to be the options:


elogger, complete OSD/GPS, $309 total plus (Fma copilot needed for return to home?) (if i just want to record to a file and later overlay this data, do i just need the main module, the altimiter and speed sensors?)


rangevideo OSD, these guys offer a $355 package, but it includes GPS return to home, which is great, but if i just want basic OSD that can be interfaced easily, its a bit pricey (though i think for $355 you must add fma copilot to it, so higher cost, and probably the same is true with elogger?)

cheaper OSD, but again, not sure how it interfaces or if it does onboard recording of a file: http://www.gentles.ltd.uk/gentvu/altiosd.htm ($174 US)..

cheapest OSD, remzibiOSD, $117 or so total, even has some limitted GPS, but no return to sender (can this return to home be added on?)


For the money, if return to home can later be added, the remzibiosd sounds like a steal? Or maybe the elogger, piecemail style?

Or is there some major reason to go $355 some bucs for the rangevideo.. does that rangevideo system beat out these other two with ease of setup or use overall? IE: which is the easiest to just plug and chug (i understand that with the remzi one, you must do some splicing and soldering for the video feed wires, i dont think this is the case with the others?).

Am i missing any potential parts in this list? My plane is a brushless twinstar II (specs http://www.tech-stew.com/post/2012/0...instar-II.aspx )
Thanks in advance

Nice video posts..

I like the rangevideo way points and mah readouts on the battery..

The remzibi arrow, showing the point of origin is real nice too.. but on this OSD, with just voltage, what are the points for the flight battery/ video battery, where you would want to bring it down or how would you tell based on voltage alone, wouldnt you need an mah readout..

The autopilot thing is very interesting.. is this a result of interfacing with fma copilot (on any one of these OSD setups?) Does autopilot/return to home require any special plane hardware aside from the fma copilot type device?

And is there much calibration that must be done prior to take off on any one of these setups.. is it done with the push of a button or does it need hooked up to a laptop before you take off?

ahh I was just about to post a link to nghobbies website for your osd

I just ordered the ezosd and antenna tracker from Zoltan it shipped this morning... couldn't wait for eagletree to come up with something after all

I'll post a review of the OSD/ tracker as soon as I receive them, got some pictures of your pan/ tilt for the antenna tracker Sander ?

I see visually the differences between these various OSD devices..
but..

What is it that eagletree lacked that the EZOSD others dont?

Can someone point me to a video link for an example EZOSD.

I'm assuming its uses GPS data for "air" speed right.. ie: ground speed..

The remzibi and EZOSD are similarly priced, do they offer the same features.. Can all of these, rangevideo, ezosd, remzibi, elogger, all interface with cached google maps to generate a plot, either during or after flight too?

It also sounds as if Remzibi will interface with copilot and ardupilot in the near future after firmware update.

Markm, thanks for your post! I wish I had time to do a feature comparison matrix for all the OSD's out there. Maybe somebody with more time (and less bias!) than I can do this.

Here are some things that differentiate the OSD Pro from the others. Others will comment/correct any errors:

1) OSD Pro has voice announcements/voice warnings.
2) OSD Pro has graphical waypoints and distance to waypoint display.
3) OSD Pro has the "RADAR" feature showing where you are vs home, and vs your waypoints.
4) OSD Pro has full data logging capability, and includes software to graph and play back your flights.
5) Eagle Tree offers a wide variety of sensors to enhance the OSD Pro, including barometric altitude, pitot/static airspeed, G-force, and others.

Here are some specifics of the OSD Pro, that need clarification from some of the above posts

* Regarding RTH, the OSD Pro has built-in GPS based RTH, with no additional sensors required. We are working on enhancing RTH to use thermopile (FMA) sensors short term, as well as inertial sensors medium term. Additionally, we plan on adding stabilization using these sensors.

* We are developing the Eagle Eyes ground station that adds the following capabilities, when combined with the OSD Pro:
- full data telemetry to your PC, encoded in the video stream
- antenna tracking
- diversity
- video splitting

Goal is to have this shipping over the summer. More info on the Eagle Eyes is available here:

http://www.rcgroups.com/forums/showthread.php?t=1048046

The lowest cost OSD we sell is the standard OSD, + our eLogger. This package is $69.99 + $44.99. It displays text of various parameters, + does full data logging. To this you can add GPS, and/or a variety of other sensors. It is described here:

Bill, for Eagle Tree

**an overall OSD matrix would be an awesome thing on here, maybe showing whether each includes: GPS, return to home, weight, etc.

Nice I do like the ability to add other sensors down the road..

So it sounds like the 100amp pro package with GPS has speed and altitude right? (GPS based), so no need for extra sensors..

Does this pro model also show an arrow pointing back to "home" per say.

I'm assuming with your forthcoming telemetry PC ability, it will include google maps integration?

Hi Mark,

Yes, the 100 amp Pro with GPS gives you GPS speed and GPS altitude. Over time, you may become annoyed with the shortcomings of GPS altitude (it can be finicky), and consider using our barometric altimeter as an option.

Yes, the OSD Pro has a home arrow, and additionally the "RADAR" icon points toward home.

Yes, we already have full Google Earth support. The OSD Pro's data can be downloaded, and exported into Google Earth after your flight. In addition, with the Eagle Eyes, you will have real-time Google Earth support. That feature is already completed and works with our dedicated wireless telemetry products.

Regards,

Bill, for Eagle Tree

If anyone can give me the values to some of the ?'s on the grid, this will help, or let me know if any of this is wrong, ill change it later on.

Thanks

Hi Mark,

Thanks for doing this! Re ET, there is no need to solder/splice anything, and software to tweak/config the OSD is included. But, most of the OSD config can be done at the field with on-screen menus.

Bill, for Eagle Tree

In the matrix regarding Remzibi OSD and RTH/autopilot you do not need FMA CPD4 Co-pilot for 70$. In fact you would need FMA sensors (43$) + ArduPilot(24$) and firmware upgrade.

RVOSD weight 32g, This includes power management on board with voltage selection 5v//12V to camera and transmitter, voltage is filtered to remove interference coming form the ESC//motor.

Direction and distance to waypoint is included.

The best configuration for the RTH and AHI system is by adding the FMA heads, This will allow the autopilot to fly your airplane back on less than ideal conditions unlike the GPS only based autopilots. However RTH can also work with GPS only but you will have hard time configuring it. Up to date there is only videos showing successfull RTH from Dragon OSD and RVOSD, the rest are still working on that.

Note that the autopilot//AHI system does have provision to detect when the plane is flying upside down.

The cost of the complete RVOSD system is 335 USD this include:



External temperature sensor already included in the package in case you dont want to use the internal.

Finally we are working on a ground station that will add data logging + google earth + antenna tracking. The OSD is already sending the telemetry embeded in the video signal.
