May I suggest a back up battery system. Larry F. and Mark L. and probably many others have done this. A battery in good condition will last longer than you will need to get out of airspace, should you have an electrical problem. I never did it, but will definitely build it in to my next aircraft.

Heath - Lexington, SC -----Original Message----- Awhile ago, someone asked whether it would be a good idea to have a small gasoline engine in a plane and use it to keep the battery charged, instead of having an alternator on the engine. Many people (including me) said this was impractical and a regular alternator works fine.
