MMMV3 Programming Question - RC-Monster Forums

I'm firing up my LST2 conversion (no pinion yet). I know that when you turn the MMM on, you hold the trigger full throttle until it beeps, etc. But one thing that I don't recall happening, that IS happening, is that the ESC fan comes on and stays on. It's also not going into the calibration like it should when holding the throttle. It just sits there w/ the fan running, flashing red. What to do?

Zero trim on tx? Auto lipo cutoff or custom compare it with the actual voltage going to the esc.

According to the LED sticky, flashing red (or green) means it is seeing full reverse (or forward). The fan staying on is a bit weird though; it doesn't mention that. Like bruce said, set 0 throttle trim, EPA for forward and reverse set to 100%, and make sure there is no brake dual rate set (in Spektrum, it's one of the readily accessible settings that can be made on the fly, and lays "on top" of the reverse EPA setting).

Intersting... SO... perhaps I need to swap the motor wires, or reverse the throttle switch on my Rx? I didn't think that it mattered from the motor to the ESC just how the wires were plugged in, but maybe it does. I have the manual, but I'm sorry to say that I don't totally "get it". I have three wires on my Neu can. Blue, Yellow, and Pink. I wired the leads to the ESC just like they are wired on my ERBE with the same can so it should be ok. The only thing I'm NOT sure of, is which holes my red, black, and white leads are plugged into on the ESC itself. THAT is what I thought didn't matter.

I'll let you know.

Ok, that did it! Reversed the throttle switch on my RX, and it's now programmed! The fan went off immediately after programming was complete.

Thanks guys!

The fan stays on until the unit arms, so that's normal.

Good job. If you're Tx is a Futaba, the manual specifically mentiones about reversing the throttle.
