Ground speed < some threshold
AND
Distance < some threshold
AND
Height < some threshold THEN MOTOR OFF

just my two cents.

I think there is a malfunction and maybe it is better that I send RVOSD to you for a repair. My RVOSD5 is one of the first ordered on 06/23/2011.
My RVOSD5 is one of the first ordered on 06/23/2011 with order 14144.

I just try to Contact Range Video support two times with contact page form but no response came. Please reply to me with some indications on returns because I would like to repaire RVOSD and restart to fly... thank

Replace the top board.

Do you mean that I have to replace with this ? http://www.rangevideo.com/index.php?...roducts_id=259

But maybe just a repair ?.. and perhaps it is better that RV check the two boards. Anyway I'm a fan of Range Video OSD and one of the first owner of the GEN5 but now I'm a little disappointed because from two days none reply from Range Video support.

Get ready to wait for a long time, in my opinion RVOSD is dead on my list...

I had the exact same issue a few months back. Had to send it back to RV for repair. It took a little over a month to get it back. But it works great now.

i had the same problem ,

i changed the bearing in my motor and fitted a new balanced prop , problem solved

His issue is not related to vibrations caused by an out of balance motor/prop. The motor isn't running. RV replaced my OSD when mine had this issue.

Today Range Video support send me a new graph board. Great.. I hope to restart to fly soon and I can truly be considered satisfied of RV support. Thanks Vova and thanks Alex.

It's easy to replace the graph board ?

Plug n play.
You got spare clear plastic heatshrink?

Do you know a shop which sells wide clear plastic heat shrink to cover RVOSD? Thanks

You can buy on ebay. I forget the size but search in this thread and you will find it. Also, you can carefully slit the old one off and put it back on with some Scotch Tape.

Yes, Vova put heatshrink in the package also.

Regarding heat shrink tube, this one works great: http://www.ebay.com/itm/66MM-42MM-PV...item7914af59ba

Heres my latest effort from Downunder. Its my latest platform, a 3.1m flying wing called BigAss. It carries 30,000mAh of 3s lipos. (6x 5000/3s).

Max distance 24km (15 miles). I engaged the RTH at about 12k out and was a passenger for the last leg of the flight. The autopilot tracked perfectly, right down to zero, and then orbited waiting for me. It was beautiful to see, like a cruise missile, or homing pigeon. At one stage I removed my goggles, put down the RC and walked 100m from the GS. I phoned the plane, and it responded with an SMS of its coordinates. I love this stuff.
Congratulations to Alex for a truly brilliant piece of software and hardware engineering.
Cheers

Tapanappa to Newland Head, South Australia. Flown with Dragon Link and RVOSD Gen 5 (11 min 3 sec)

Quite an accomplishment, congrats! What exactly did you phone on your plane? Or do you have you planes full specs posted somewhere?
