Hey guys. Another noobie question. I'm setting up my MFU and I see this VR1 adjusting knob. Its says 3chdead band trimmer. What does this do?

this is a fine-tuning for the neutral position of your trim for the horn and 5th wheel operation . This will also effect your engine-shut-down and lights .
Just set it up as descript on page 6 of the manual.
So far I don't remember ever had to mess with it , at least by the radio-systems I use , JR / Futaba and Spektrums it did work right from the get go .

If you get confused with Tamiya's channel descriptions ( since there manuals are written for transmitter stick-mode 4 and here in the US we use mainly stick-mode 2 )

Wild Willy - thanks a TON for that. I was getting there by experimentation - your explanation is perfect and perfectly timed for me.

Thank you for that! The Tamiya manual isn't really the most helpful thing in the world.

If I'm not using the servo for the trailer coupler. And I end up using it to control my lift axle. Should I hook up it to the MFU or just run it out of the receiver?
