I am installing Dynon AP servos in my 2001 built RV-8. Before I start on the Pitch servo I need to relocate or replace the aft battery that is currently mounted forward of the bell crank right where the servo needs to go. Welcome any tips on the install and / or alternate locations for a second battery. Do I even need a second battery? I/O 360 with dual Pmags. Future instrument panel will be Skyview HDX with avionics backup battery. Are there any RV8's out there with AP installed and can share pics?
