Hi there,
here's another little onboard video taken with my EOLO in late september at the northern Black Forest / germany.
Quality is moderate, not only by the compression to ~ 6MB but also the cam. Particularly it doesn't like looking directly in the sun ...

Greetings
Rudi

Very cool

What is your setup and what camera did you use?
If you could post some pictures too it would be very cool

Edit: Just noticed this is your first post - welcome to the forum

Hi Lorents,

It's a nearly stock eolo, motor is a hacker B40/L9 with JETI controller and 14 teeth gear at 12V/2Ah NiCd. The tail gear is
selfmade from a of an old 5 1/4" Harddisk.part
the cam is something ( 2nd pic ) , from ebay e.g. , ( don't ask me how the german "vorderer rechter Landekufenausleger" is called in English ;-) mounted at the front-right "leg" in a shape-part made from a champaignbottle cork and glued to the "leg".
The cam itself has meanwhile gone to a better world without overvoltages ;-), but the transmitter module is still intact. The new cam will be mounted separately from the TX, so I can optimize the position of the cam for sight angle and vibration damping ( and interference from the motor controller ) independent from the TX/antenna position, which should point straight downwards for a half-sphere beam characteristic directed to the ground, I guess.
( In my just posted video you can see the noise at some points caused by the sidewards beam/ shadow of the old antenna position )

regards
Rudi

the quality was better than I thought from such a small camera and transmitter.

I always admire people who can make their own parts. In the modern RC hobby world with precision and intricate parts, I can not even begin to think of fabricating heli parts.

Could you be more specific about the manufacturers and models of these little cameras? Or, it is this "vorderer rechter Landekufenausleger" that can not be translated into English?

Hello SBK,

-no, that ominous "rechter vorderer ..." is just the front right rod between the skid and the rest ;-) - how do you call it ?
Those cams - I've bought it via ebay, you can see dozens of this kind if you search for >funkkamera< or - to pick any one - article No. 7563594433 at ebay.de, for example. Price about 60 Eur ( maybe 70 $ or so). The radio transmission is o.K. but the with the camera ( particularly the optics ) I wasn't very pleased. You can see the blurred corners, and the slow reaction to changes of light is also not very good.
Now I've combined the TX module with a 340 TV lines CMOS camera module from Conrad , Artikel-Nr.: 150026 - 62 which gives a much better image .

But it still has to proove its quality, at the moment I have to do some work with the heli itself. The last crash was clearly caused by just not seeing exactly the direction of flight, so I'm putting a jet ranger fuselage with _really_ visible colours to it as a "first solution".

My dream however is a see-through video-display to have "cockpit view" simultaneously to the normal model sight. I've seen suitable devices on the web, but they were all too expensive for their resolution So I've to go on searching.

Best Regards

Rudi
