Sorry forgot to add. Esc should work on any channel that the esc is plugged into on your receiver.

I purchased an mtronics 25 amp esc recently. Wired it and seemed to work. I then started to install to the model, wiring etc and fastening in then started the set up instructions. When switched on the blue and yellow led light alternately but no red light whatever I do. Tried pressing the button and switching on with button pressed but not powering the motor and only get blue and yellow lighting alternatively. Given up, very disappointed as I don't think these units can be repaired.

Thanks for your inputs .... will have another look tomorrow

As far as I can understand it, throttle control is always defaulted to Ch 3 no matter what stick the equipment manufacturer assigned as throttle control.
Usually each stick is assigned a particular control function.

According to the video link I sent, it is very clear that once the “programming” or initial setup is performed, the ESC should work. Your description of your problem indicates that programming either failed or was improperly done. I would make another attempt with the ESC plugged into ch 3 which is the “normal” throttle channel. On your transmitter unit, according to the user manual, the throttle control is on the right hand stick. I would try the programming procedure one more time being absolutely certain that you do not leave out a step. If it still does not work, you may want to have conversation with your supplier of that item about replacement.

“what difference does receiver mode PWM or S-bus and PPm ?“
Unfortunately, I do not know the answer to that. I bet that your user manual would explain it.

Good luck - hope you get this resolved.

Esc enters set up ok
Push throttle forward then centre red light comes on 👍then reverse .... but motor still just runs continuous ?
Is there issue with ESC ?
what difference does receiver mode PWM or S-bus and PPm ?

Hi,
To try and explain this easily it depends on what you want on what switch or stick on your transmitter.

What i do is, if i want the left up/down stick to operate a throttle i would plug in a servo it to the receiver and wiggle the left stick and if the servo dose not work i would then move the servo to another position on the receiver un till it worked.
Then do the same thing again for a different function until i have everything operating as i want it to on the transmitter.
I hope i am not trying to teach you to suck eggs.
Obversely it can get more complicated depending on how you set up your transmitter.

More progress .... my throttle is on right stick does this change the channel it connects in to ...

Please try this:
Watch the YouTube video on connecting and programing your Viper ESC.
Hope this will help.

Hi,
How have you connected your throttle and rudder to your receiver ?
Maybe you can post some photos of your setup.

Getting there .... but throttle and rudder on just 1 stick rather than split ? Any idea why ?

Hi.
It’s sounds as if you havn’t set up the ESC to the unit.
I can explain how to do it,but first try following the attached instructions in the phot I have taken for a Mtronics unit same make as yours.
It really is very easy.
Hope this helps
Regards Bill

Some progress made ...powers up and servo works .... all controls on one stick at moment .... and no throttle control just continues to run ...any ideas ?

Hi,

You should connect your ESC to channel 3!
Make sure you bind the receiver to the TX!
