Greetings,
First post here, hope this lands in proper spot. Please forgive me if this is asked improperly!
Trying to figure out if this is possible, (so far my testing/trying says no luck, but you never know unless you ask.
Can Tiny Mixer (in “Tank” mode, 2 stick control) be used to run both motors on throttle channel for motor speed and then use elevator channel to vary the speed of motors independently?
Application is,
Coaxial Helicopter need to be able to control height with both motor speed with “Throttle” and the control YAW with “Elevator or Rudder” channel
I have esc’s for my motors and they are set to have 1 motor CW and the other CCW so I need way to run up both motors yet be able to have independent speed control for Yaw.
I have tried to get the Tiny mixer I have to do this however I have no output to one motor in tank mode
Esc’s are good and I can swap motor connections @ Tiny Mixer motor end and output remains the same, in my case I only have output from “Right” motor Pins nothing come out of “Left” motor pins when in tank mode (no mix mode)
If I go into “Mixed mode” I will have output from both motors, so it seems that Tiny Mixer is Okay, but I guess I just aint smart enough to figure out a way to connect it in Mixed Mode the makes any sense to me. I would like Throttle to bring heli up to desired height and then use ele or ali to induce “Yaw” command for heading direction
Tried it about every way possible on RX connections in Mixed Mode and can’t seem to make it work, that is why I’m asking about No Mix Mode
Motors do have caps across the power terminals (ceramic 0.01uF) and both motor and ESC’s so far work flawless when connected to RX Thrd (one at a time) by itself
Using my Spektrum TX thats flies all my stuff okay
Sorry for long first post !
Any help provided would be much appreciated !!!
The tinyMixer is kind of dedicated Mixed mode.
It will merge the two channels to control in Tank mode with an “INV” input to change orientation when the Tank is flipped upside-down.
The module can be set to “no-mix” but it is a procedure you cannot do on the fly:
Switching between Mixed/No-Mix mode:
• The tinyMixer is shipped in Mix mode by default. It can be switched between Mix and No-Mix (two-stick,
aka “Tank”) driving mode. (Invert can be used in either mode.)
• With the LR wire disconnected, push the stick to the top and hold (the LED will flicker). After 4 seconds
the LED will blink repeatedly to indicate No-Mix mode, or go solid for Mixed mode. The robot’s power will
now need to be cycled to reboot into the new mode. (Don’t forget to now plug in the LR channel).

Hello,
Thanks for your response!
Yes I understand mixed mode,no mix mode and how to change between the two, that is not the issue.
What I’m trying to find out is this:
Can Tiny Mixer (in “Tank” mode, 2 stick control) be used to run both motors on throttle channel for motor speed and then use elevator channel to vary the speed of motors independently?
If TRUE then mine will not do this, because it only has output on ONE of the motor control terminals
Please see original question I posted for exact details
Trying to determine if this has the capability to do what I need.
It seems it should, however in NO mix mode the tiny mixer I have only gives output in one set of pins to motor esc’s leading me to believe my tiny mixer is not functioning correctly
If you could confirm the correct expected functionality of tiny mixer in two stick mode that would confirm or deny if my tiny mixer is “Good” or “Defective”
This is in entire purpose of me posting this question in the first place
Thanks so much for your time !!
PS: I understand completely how to change mode, just needing to know the specifics of no mix , two stick mode
I don’t understand what you are trying to do.
The module will always mix both channel to give a mixing of the two on two motor output.
That’s they way this module is made and the purpose it’s intended to be used.
Okay,
So safe to say if not,
" The module will always mix both channel to give a mixing of the two on two motor output."
It is DEFECTIVE?
Because mine will NOT GIVE ME TWO MOTOR OUTPUTS, only ONE as described in detail in my original post
First thing you would have to do is to confirm you are in Mix mode:
Switching between Mixed/No-Mix mode:
• The tinyMixer is shipped in Mix mode by default. It can be switched between Mix and No-Mix (two-stick,
aka “Tank”) driving mode. (Invert can be used in either mode.)
• With the LR wire disconnected, push the stick to the top and hold (the LED will flicker). After 4 seconds
the LED will blink repeatedly to indicate No-Mix mode, or go solid for Mixed mode. The robot’s power will
now need to be cycled to reboot into the new mode. (Don’t forget to now plug in the LR channel).
Once you know it’s in mixed mode, you can try again with your motors.
Make sure you have you sticks centered at power up as suggested in the user manual (HERE).
Obviously, you can try to invert your input channels as well as your ESC’s to see if the motor that move change location as well.
Thanks for the help
I just put in trash can and did my mixing with DX6
Your responses did not help me in the least, don’t know if you actually read my 1 post but by your responses you either didn’t read it or did not understand the problem and we have a problem understanding one another
Your last response was really immaterial because all I was doing was trying to confirm operation in NO mix mode so trying stuff in mix mode makes no sense, if you had read my original post all that was covered and already was done before in posted here in the 1st place
You know trying to not waste folks time and stuff like that
No hard feeling and thanks again for trying to help
BTW I also have Tiny ESC from you guys and I work Flawless!!!
Hope you have a great day my man !!
I’m sorry if you are not happy with my help but the explanation provided do not seems clear to me.
Anyhow, if it’s defective we will replace it (granted it’s been ordered lately)
I have no idea how it react in “no mixing” but my understanding would be the channels go directly to output, but i’m not sure.
This is really mean to be used in Mixed mode and there are not real benefit of not using the mixing mode.
