Trim system

On the Sonex the D180 haas 2 inputs for the tach. I take 1 off the left mag and the other off the Jabiru alternator.
On the Panther I have GRT 6 cylinder EIS and take the tach signal off the rear mounted SPA alternator.

ok.... great. I have the rear SPA alternator also. did you just hook the tach to one of the yellow wires? or is there something else inline?

I checked W&B for both engines. Aerovee install empty weight 688. For Jabiru 3300 install 698.
As for tach may need a resistor in line, should be in instructions for instrument you are using. You have 50% chance of picking correct output lead of alternator, only 1 will work. If it doesn’t work switch to other output lead.
