Not to disagree I know of a RV-4 with this set up and I heard no complaint. I love the idea of a simple day VFR RV. I looked into this. For bare bone VFR cruise I got about 4-6 amps, for worst case everything (Comm. transmitting, flap motor running, boost pump on) 9.1 amps max*.RV7ator said:In short, a lone SD-8 makes a wimpy, expensive, clumsy source of electricity.

Not sure of the price, but it's self exciting and rated at 30 amps.
