I did some searching for the ZLog and the Eagletree setup and I've read some posts about them. I'm looking for current opinions/suggestions for the most reliable and accurate altimeter + OSD setup.

Thanks!

In my opinion zlog is superior to ET, had both sent back the ET. Mount it in a foam pillow, not the closed cell foam but the open cell type. Have it programmed to 0 out upon power up. Go into a hover at 5-6 feet see what it reads go up 25-30 feet for a second or 2 then come back down to hover at 5-6 feet and use that number as your 0 point then go on up to altitude for your shoot. They arent exact by any means but this procedure has worked well for me in the past.

Thanks for the input guys.

Robert,
I guess when you have that fancy upgrade to the DJI, you don't need the ZLog.

Mike,
Thanks for the PM. I don't need anything extremely accurate. If I can get something that will give me the heli's altitude within +/- 10 feet, I would be happy.

I have no previous experience with OSD packages and I am just about to invest in a telemetry set up. Obviously altimeter accuracy is going to be one of my major options. From what I have read in this forum altimeter performance is not exactly there is it?
So . . .
barometric alt sensors don't give you a consistent and accurate reading.
Zlog, ET, RV and etc. . . they are all the same are'nt they?
I'd be happy to see what everybody tinks.
Cheers,
Ahmet

Your asking the wrong forum. Check out rcgroups under fpv. I just did a bunch of research on this topic and one of the best osd out there is from rangevideo. It even has autopilot back home as failsafe in case of radio loss.

OSD wise you may want to look at dragonosd (check RCG) lots of options including differnt altimeters from sparkfun and others. Cheaper in price than RV and smaller.
