Thanks Bill for the fast answer.
I opened a ticket and they told me to send in the osd.
Can you imagine any "easy" defect? If its only a loose soldering I can fix that on my own.
I've got an Multimeter and a soldering iron, and perhaps you have already an idea were to look at.
If not, I had to send it in, but this will take another weeks and I want to get my system run. Winter is coming and I don't want to wait for next year to fly fpv.

Thank you

Finally we found the defect and managed it to repair the OSD.

Thank you Eagle Tree Team for the amazing support.

Keep on doing so.

i was disconnected from this forum some months,and i remember a post where somebody talks about to the need of disengage the RTH minimum altitude of throttle to use the RTH option in a boat.i remember that bilpa agree with that "boat mode" update.
is there posible to do it?
or at least,it's possible to avoid this limitation?
i know that this is an important security feature,but i need another OSD with RTH feature for my long range boat,and i prefer to use eagle tree.

Counter5001, great news it's working now. Thanks for doing this!

xiro6, yes, the "boat mode" is there now. It's an option under the "Sensors and Units" menu. The menu is called "Enable low altitude RTH(RTFM)" Do let me know how the RTH works with your boat. I think you'll be the first.

GPS receiver not detected, don't know what to do to get it working... any simple fixes? running off 3s flight pack. Everything else seems fine

oh also... is it possible to configure the left side speed bar to airspeed?

Hi Dave, is the LED on the GPS blinking? Also, can you confirm that you have the GPS connected on the top connector of the eLogger, when the OSD is connected to the bottom connector?

yes, to show airspeed, just set "Use Pitot Spd for RTH/Ladder" to "Yes" under the Sensors on-screen menu.

Hi Billpa, one question about RTH - (test in ver. 8.60-8.63):
when model need to increase altitude - OSD don`t turn motor on "climbing" - only some shot time, and also don`t set "elevator" on climbing.
Now, when I go wizard RTH, I set _full_ throttle and _full_ back elevator - but in air (and also in simulator) I see VERY small throttle and very small "climbing angle" on elevator. What I do wrong????

In real flight model in 70% case lost altitude at time and (one crash: when I start, I rise at 40m, then take glass (but glass not working) - there I turn RTH "on" for increase altitude and give me time for fix glass - but after 1 min model crash

P.S. Also I see another case - throttle may be go at 50 to 100% and back on 50% after 1 sec, then repeat there - 50....100....50...100...50...100 - why???

Hi catsw, sorry to hear about the issue! I think the problem is that you have set the "cruise speed" too low. The RTH will not use the "climb" throttle setting if the model's present speed is less than or = to the cruise speed setting. This is to keep from pushing your model past it's max speed. If you increase the cruise speed setting to be somewhat above the normal cruise speed, the issue should never happen. Also, note that with software versions 8.75 and later, you can disable this feature by setting the cruise speed to 0. We'll be renaming this or eliminating it entirely in future, due to some confusion.

Thank`s for solution, but I set OSD in Cularis, Cularis cruise speed is 20...25 km?h, after one crash I set 35 km/h, OSD is try to set this speed - it`s ok, but I don`t see maximum set climbing of "elevator", "elevator" change to climbing so small, but in wizard I set FULL angle to climb, in simulator and in fly I can`t see so math angle in this. May be something in tuning PID controllers is wrong? (all set default)

In wizard I set FULL throttle and FULL angle of climbing, in real I see small angle of climbing - and, as You wrote, big speed and then small throttle.

If I reflash OSD to ver 8.75 and set cruise speed to zero - what logic RTH in this case???

P.S. sorry of my English.

Bill - new beta 8.75 have a coupe of serious bug:

1st - it halves the current readings - in logger idle 0.8A, in OSD 0,4A !
2nd - as #1, maH is halves the current readings - in logger 200mA, in OSD 97ma !
3th - it twices the power readings - in logger 6watt idle, in OSD 14watt !!!

To All - don`t risk you model - be careful in this case!!!!!!!!

It`s easy to test at home - connect Logger to PC via USB cable and press "Live mode", then turn on you video transmitter/receiver and glasses (or TV) and compare this data.

I`ll second catsw. The behaviour of the OSD pro is just like in my case.
Maybe it is a very special russian problem due to our special weather? I wonder why nobody else faced the same issue.

Ok, Bill - IMHO I fing the bug:

At first - when upgrading at 8.75 - need to do 3 RESET - PowerPanel, Logger and OSD.
Then configure OSD manually - all Ok.
But, if save configuration OSD, do OSD "factory default" and load configuration back - bug returning. (it halves the current readings and all, wrote me at post 118)

Then bug happing when do Save/Load configuration file of OSD.

Bill, please, repeat this step and see, and I wait You answer ASAP!
