Heron servos dont want to work with Omnibus F3 OSD with Inav

[312_HeRa]

Hello.

First of all I want to appologize of writting English. My German l. is poor. But I hope you will understand my easy english.

Can you please help me with issue on my Heron, which I would like to build as FPV.

Omnibus F3 OSD with Inav (newest 2.4 or older 2.3- doesnt matter)

Heron with built in servos from manufacturer(As far as I know, its analog Hitech )

When connected via Omnibus in manual mode(without stabilization), servos go into end possition and stay there and doesnt react to movemnet of the sticks.
If I connect other analog servos, they work correctly
If I connect servos without omnibus , the also work ?

Could you please help me to set ip up to make it running ?

Any hints or experiences ?

Thank you very much beforehand

Hi,

so you don't see any movement for the 4 servos (aileron, elevation, rudder) in the Inav Configurator Servomonitor, but the Hitecservos will move to maximum travelway?
And some other analog servos will not?
That is confusing..

Currently i think the error is in another place, but not the hitec servos, especially if they work properly without Omnibus F3.

i think you already follow this instruction?
https://github.com/iNavFlight/inav/wiki/Fixed-wing-guide
or https://github.com/iNavFlight/inav/blob/master/docs/INAV_Fixed_Wing_Setup_Guide.pdf

You have to give us some more details how do you have exactly setup inav and how exactly you have done the wiring (which servo is on which UART/PORT)?

Hello Andreas

Thank you very much for your answer.
No , it works with other servos ok. See the videos please. Same settings , different servo.

Thank you very much for any tip

Hello again.
Motor on PWM1(works correctly), servos PWM 3-6. RX UART1, GPS UART2. FC powered directly form batery on pin Vbat. FC powers only RX and GPS. Servos are powered from S-BEC regulator of motor via separate rail on wich are only connected signal cables from FC. I try servos in mode : MANUAL

Thank you again for any hint.

Hi,

did you try some of the other heron servos, too?
are they showing all the same behavior?

just to be sure
- check if the servos are really controlled with about 21ms and not 14ms or less
- check if servo impulse for the middle is 1500us.
- check if the heron servos are correct in neutral position

i'm sorry. i have no further idea.

Hello again and thank you for any hints

Quick answers to your question :
Yes, all Heron servos are the same
All other types (as seen on video ) works great

Sure on 21ms (also tried more - doesn thelp)
Impulses are ok (Also everything is OK in servomonitor

Thank you very much
