I believe the only Aeronca that would meet that requirement would be
the Aeronca Sedan (I could have the name wrong). Its been a long time
since I owned my Aeronca though. The 7EC has full electric but is
tandem. However, I would consider it bad for to have an Aeronca with an
electrical system. The nice though about the Aeronca was that it was
simple and not expensive to maintain. In the last 5 years I've probably
spent $30,000 in maintenance just on electrical issues (not counting
avionics) on my Mooney.
