Gave Heading Hold a good test today. Keeps direction nicely, but loses altitude slowly. Any ideas how to fix this?

I would advice trim the plane fist then set the servo neutral in Osd.

My MPX TSII is about to maiden any day now
Here's how the OSD and all related electronics look like, spread on a cutting mat.

(I'm using a $28 FrSky receiver with PPM and RSSI outputs, which I like a lot, as it saves quite a few wires)

Hi guys,

Maybe someone can help me out, I've had a 'hard landing', lots of pins bent along with the DL Rx. Now everything appears to turn on (can enter menus and see stick movements through the wizard setup on RVOSD5) (DL works fine also when RVOSD5 bypassed) but the problem is that RTH goes into a high frequency flicker & will engage RTH after 20 seconds or so in a spluttering kind of way.... does anyone have an idea as to where I should go/do to solve this.

Regards,

WO

Hi,
I also use FRsky receiver for my Futaba radio. It has PPM and RSSI with 10channel.
But I have a serious range problem. Max range I reached is 700meter. Most of time I lost control after 450mtrs. Thanks to RTH I didn't lost plane so far.

Does anyone have this problem?

Hi. Any idea why my menu is acting weird, like for instance, I can't toggle anything except 1-3 items, and when I toggle them, an item far above is toggled, not the active one on the screen.

It's like the menu item number has some weird offset?

Any ideas?

Wrong sensor firmware. Did you flash the board with new FW?

Is that something I can do on my own? (Btw, this is RVOSD v4)

When I bought it used, it was said that it comes with the latest firmware.

I don't know much about RVOSD4 but this will allow you to update the firmware.

Hey

i write in all instances of known forums, to get help. Ive the RVOSD gen 5 with the 70A current sensor, and get only 0,5amps. (with a 30A Motor ive only 0,5a, all the time) i got a second sensor as replacement, but it wont work too....

if i bring some volts (2V) to my OSD Sensor Input Pin, my OSD shows me current. so the OSD itself is okay. i measured the outgoing voltage aof my sensor: ive ground, 12V and the yellow wire shows 0,0000V....:/

But both currentsensors are bad...whats up?

not false polarity, no burnt pcb, seems like a brand new sensor (what is is).

But both shows nothing....:/

can anybody help maybe?

Do you have thé in and out respectéd on thé sensor ?

I dont have any Documentation about where "in" and Out" is...but i think, yep

It's printed on the current sensor on one side.

Mark

on my 70A sensor is nothing like in / out. but for the test, i reversed input / output. same problem.

Check what sensor is selected in the menu.
