Hi Dirk,

I have solved my pronblem with your help.

The error was the ESC calibration.

Many tanks
Walter

The YT video describes a similar problem as you have and shows the calibration of an ESC.

Hi Walter,

You are starting from the wrong premises. The ESC does not get a negative control value from the TX.

The ESC gets a pulse width modulated signal (PWM) between 1000ms - 2000ms from the RX, the center position corresponds to 1500ms. From this the ESC generates a rotating field for the connected brushless motor.

Exactly with this PWM the servo on the RX on Throttle CH 3 works perfectly.

Would you like to send us a link with a manual of the ESC, then we could see how the throttle travel must be taught into the ESC. Under the name of the ESC "FullPower PRO 6A BEC" I find different variants of an ESC. Which one is it exactly?

Greetings
Dirk

My ESC is a FullPower PRO 6A BEC.

But my doubt is: if the regulation curve is negative with the stick in the down position, how can the ESC/motor run ?
The motor will run starting only with the stick in the central position, increasing to full speed with the stick in the uper position.

In my opinion the current recgulation curve is only suitable for endothermic engines.

Walter if you need further help, then you should also give us some more information.

Now that it is clear that it is neither the TX, and its programming for CH3, nor the RX that is the problem and we can also rule out a problem with deviation.

So it would be good to know which ESC you are using, regardless of whether it is new. It would be best to tell us the name of the manufacturer and the type of ESC.

Hi,

I try to put a servo on CH3 and it works properly.

My ESC is a new one.

Maybe it would be good to test the output of the receiver first, if it is delivered the whole way. You could simply connect a servo there.

If on the channel 3 the servo works properly, then I would try to reprogram the ESC with the entire throttle travel.

BTW: The ESC is not from the RC-Car or Ship?

My model is a simple airplane with a brusheless motor and ESC

Thanks to DIY-Multiprotocol-TX-Module project. I ported this because I got a car that uses the Dumbo protocol.

Entry from the manual is below. Due to memory constraints this protocol is not available in Devo6 or Devo8.

Please look in the test build list for [hexfet]nightly_build. Not posting the direct link because it changes with each build.


The Radiolink protocol supports Radiolink and Dumbo receivers.

The protocol supports up to 8 channels. Default channel order is AETR. Telemetry is implemented using the Frsky telemetry layout. The following values are supported: VOLT1, VOLT2, RSSI, LRSSI, and LQI. Telemetry is not supported by the Dumbo protocol format.

* VOLT1 - Receiver battery
* VOLT2 - Main battery
* RSSI - Receiver RSSI
* LRSSI - Local RSSI
* LQI - received/expected telemetry packets (percentage)[/li]


The following protocol options are available.

**Format**: Receiver selection for Air, Surface, or Dumbo.

**Freq-Fine**: Frequency offset adjustment. Range -127 to 127. Adjusts for variances betweeen CC2500 modules. Default 0.

What heli are you flying?
What's the receiver and flight controller setup?

If it's a collective pitch heli with throttle on channel 3 you most likely have a "smart" flight controller with its own ideas about throttle curves.

Could also be the same with a fixed pitch or maybe just ESC endpoints.

Hi ,
i confirm that channel monitor CH3 is - 100% to +100%.

My TX type is V3

Channel configuration CH3
safe val = 0
min limit = -150
max limit = 150
scale - = 100
scale + = 100
subtrim = 0.0
speed = 0

Simple MIX type
curve = 1 a 1
scale = 100
offset = 0

thanks
Walter

Hi,

what can you see when you look up "Transmitter menu" / "Channel Monitor"? Is the value of CH3 rising from -100% to +100% when you move the Throttle Stick?

What is your TX Type?

Greeting
Dirk

I am a biginner and I would like a template about ESC motor control.
I try to setup it, but my CH3 stick works only from the center to the full throttle
From the down position to the center of the stick the montor don't run.

many thank in advance

Devo f12s doesn't supported by Deviation.

Hey! Im sorry to post in this old post but there is a way to check if UDP messages are the same bits for UART communication between wifi and flight controller (yellow wire)?

bonjour
je recherche un nouveau deviation pour ma radio jumper t8sg v1
je suis actuelement sur deviation-t8sg-v5.0.0-06c2f7d , je voudrai savoir si il y a en un nouveau
si oui , je voudrai bien lien de téléchargement
merci

In general look for "[hexfet]nightly_build" in the list on the Test Builds page . Unfortunately the link to that build changes every time it's updated. I don't have github privileges to update the "official" nightly build link.

The current latest build is [hexfet]nightly_build

Habe die Lösung selbst gefunden. Das upgrade über USB mit kopieren
der Dateien funktioniert nicht. Man muß in jedem Fall eine DFU Installation
mit Walkera DfuSe machen.

Das upgraden von Version 4.1 auf 5.0 bei meiner Devo10 über USB funktionirt nicht.
Es bleibt immer die alte Version 4.1 drauf.
Beim upgraden auf eine Nightly Version wird keine Versionsnummer angezeigt
und es sind keine neuen Protokolle verfügbar
Kann da jemand helfen?
