Re: What is the most economical GA aircraft??????

I’d start by looking at a Cherokee 6. They’re great airplanes and will haul anything. Plus they’re simple, so relatively inexpensive to maintain and less to go wrong, especially in the back country. I own a PA-28-235 and love it, but I also might be a little biased. ;) You can find a good Cherokee ...

So would it be possible to just add a standby battery to the aircraft?

The normal battery for a Cherokee 6 weighs about 30-40 lbs and those will last about 1...
