Thomas J. ----- Original Message ----- From: Mark R Steitle To: Rotary motors in aircraft Sent: Tuesday, January 24, 2006 8:20 AM Subject: [FlyRotary] Re: Two Alternators? Doug, I have dual alternators and dual batteries per Aero-Electric Z-14 architecture. I'm using the small 55amp ND units. They weigh about half of what the Mazda alternator weighs, so I rationalized that there was very little weight penalty to using two alternators, but a significant safety improvement. With an electrically dependent engine and all electric panel, I decided this was the way to go for me. The cross-feed contactor connects both Odyssey batteries during starting, so I am able to use smaller batteries than would be required to start the 3-rotor with only one battery. Every annual, I plan on replacing the main battery, rotating the 1 year old main battery to the aux position, and move the 2 year old aux battery to my Goldwing motorcycle. That way the main battery will be less than one year old, the aux battery will be 1 - 2 years old, and the motorcycle battery will be 2-3 years old. I'll send you a picture off-line.
