    A75 w/o alternator or starter. How difficult to put those in?

    I have a chance to purchase a home-built plane. It has no electrical system. It has an A75 engine with no generator/alternator and no starter. How difficult is it to place those in? I'd have such work reviewed someone more knowledgeable than I. Pointers to manuals and such welcome!

    Thanks in advance.

    There are no bosses on the case to mount either a charging system or a starter. That's not to say it can't be done, as I have seen several A series engines modified to accept a starter and/or alternator. If this is the plane you want, I would suggest a C-85 with alternator and starter. However, the alternator, starter, battery, wiring, breakers, etc adds up to a lot of weight on a low powered plane. That's often times why the plane was built without electrics. You might find that after adding all that stuff, your nimble little homebuilt has turned into an overweight dog.

    There's an STC for a starter it uses a battery driven drill as the starter motor plus some mechanical components to make the spinny bits go round.

    It apparently works, but is an aesthetic nightmare.

    You could install a wind generator instead of an alternator to make electrons. But you'd still have to charge the 18V drill batteries off-line.

    Kyle's referring to the Hamp Starter system. More details at:

    Continental made different models of its small engines. Some include an accessory case, which is used to provide an interface for a starter and generator.

    The A75 with a -8 suffix does not have provisions for generator or starter adapter.

    Harold Hamp passed away in 2015 - is his starter STC still active?
