I have a Kenmore Air Harbor O-320, Sensenich, PA-12.
Here's the issue: I run out of nose down trim at high cruise power/speeds. I recently put new cylinders on and during the break in period was running near wide open etc for the specified time.
IAS is between 130- 140 at these settings and I have full nose down trim and am still pushing forward on the stick, fairly heavily, to maintain level flight.
I checked the trim jack screw and it is bottoming out, so I am getting full travel. I also noticed in the logbook that in 1998 a mechanic moved the battery from "sta. 25 to sta. 60 as per the TC".
The battery is currently in the traditional baggaqge area location. I wonder if someone had moved it forward to help with this situation? Is relocating the battery legal?
