Default Angle Valve CG

Good answers, so I'll just add this. It is a MUST to put the battery in the rear location. I recommend using a standard 25 AH battery instead of a smaller and lighter battery. Don't even think about using an EarthX type LIFE battery. You need the ballast in the rear. If you're going to use lead back there for CG it might as well make lots of electricity for you!

The Doll has an I0360A1B6 with a Hartzell, and a Christen inverted oil system so she is probably as heavy firewall forward any other 8 out there. I use a standard aircraft battery. I mounted the battery and starter relays on the battery tray. Finally, I have a small tool kit mounted on the rear cargo compartment shelf above the battery. I biased the elevator trim to give more up trim. Still, flying solo at approach speed, I run out of up trim and must carry a little power to unload the stick. She flies normally with a GIB in the back seat.
