They do work at all on helis in bright sinlight. The optical is foolef. Also no gear ratio.

Can you show a diagram (in english). I have seen a few attempts at this and they all failed. One thing I am running a magnet to powered engine. No elictric ignition to hook to. The align sensor will pick up the magnet to magnet to fire but how to I connect the output line into the MRPM-AC need to know which wires go to the red and black on the MRPM-AC and if anything else is needed. Thanks

You need an Sensor like the Align sensor. Connect the plus und minus on the Power. Then connect the minus and the impuls to the MRPM-AC. When you have no RMP-Signal turn the two wires from the MRPM.

Take a look here:
MRPM AC

good luck,

Thanks Piet. I think I understand now. Will try it as soon as my order for the mrpm-ac arrives. I will let you know if I get it to work. Thanks again

If you have an RCXL ingition or a derivate you can connect the RPM output connector from the ignition directly to the MRPM AC Sensor.
If it don't work directly, just swap the two wires.

Best regards,
