Be VERY careful selecting RTH ( or any of the autopliot modes that use throttle ) on the ground because if " home " is set then autopilot will apply cruise throttle because it will think that it is...

Note pic 5, two GPS aerials, 1 for RVOSD and 1 for MFD tracker.

I am attaching some pics of my Skywalker. I will have to post 4 replies with all the pics! GPS aerial mounts on top of engine mount. OSD Tx mounts on front face behind camera. Note carbon fibre...

Hi Brilliant work. Just curious to know what DVR you are using for downlink video ?

Copied from the quick start guide for RVOSD 5, it may help.

6-Start R/C wizard, make sure to follow all instructions. If you miss any step,...

Have you checked the menu item " Enable Autopilot " ? I think it is on page 4 of the main menu. It should be set to RTH but you may have got it set to Failsafe. If so this sets all control surfaces...

Hi, Ver 5.06 and 5.06aS are both basically the same except that 5.06aS has the added coding to use the pressure sensor and pitot tube to enable the OSD to display true airspeed. I will have to check...

Try installing ver Main_5.06aS.hex and then see what happens when you engage waypoint seeker !! ( after loading some waypoints )

Have you got Live Feed Out enabled on the GoPro ? LFO in setup

See thread " Airspeed expansion status " for full info on how to connect up sensor to RVOSD 5.

Also I found this complete kit for airspeed sensing on UK website:- ...

Yes it was all from the same flight. Waypoint height was set at 500'. That would not explain the third case where aircraft carried on climbing to nearly 1000' before I disconnected. It has worked in...

Thanks for the suggestion, but that would not explain why glide throttle is not being set when above cruise altitude + cruise alt limit.
Any suggestions Alex

Hi Alex
Cruise height set 400' Alt limit set 50' Glide throttle set 1.10ms Cruise throttle set 1.70ms
Youtube video http://youtu.be/fpQ5C6rO2bg is all from the same flight. First time RTH engaged...

Ref ASI problem. See thread AIRSPEED EXPANSION STATUS post 40 onwards. Have you put the capacitors on the pressure sensor expansion board. I didn't initially and had odd readings, but with them the...

When you tilt the nose down does the AH move up the screen, and when you tilt nose up does the AH move down the screen ?

Have you got RVOSD mounted horizontally with the arrow pointing forwards?

Hi Alex
To nail this for everyone once and for all, can you confirm that the attached drawing is what should happen when RTH is selected, provided that the aircraft is trimmed to fly straight and...

Hi
The manual should ( in my experience ) say "above cruise height + alt limit" glide throttle is set, "below cruise height - alt limit" cruise throttle is set. In both your examples ( 250 and...

Hi
Set cruise altitude to 275m and altitude limit to 25m. Aircraft should then climb at cruise throttle to 300m go to glide throttle and glide to 250m then set cruise throttle and climb again to...

Hi Alex
I have been flying RVOSD 5 for 3 months now and had it all trimmed out to perfection. RTH holding cruise height to + and - 25 feet, throttle switching from cruise power when above cruise...

Hi Just a thought, have you checked your connectors from the aerial to the booster and from the booster to the FrSky module ? You should have a male to a female at each connection so that the...

Alex I have a fully functioning ASI using an EagleTree pitot static tube that works beautifully when the aircraft is moving. When it is stationary however it sometimes shows 0 but usually it shows...

How about integrating GPS ground speed and track with airspeed from IAS sensor and heading , to give a wind direction and speed arrow ?

OOPS ! Yes I did have a mix in from a ground vehicle that I had been playing with. How it got transferred to my Skywalker memory slot I do not know. Will in future check all mixes when I change...
