Hello Dan,

no i don't have lots of money but i have enough to do what i want. In
reality the reason i chose the auto derivative is because i can INVEST
loads of time equity. i can tear down and rebuild a car engine how
much does that cost ? few hundred dollars in parts. now the lycoming
I CAN NOT WORK ON and the parts would cost more than the auto engine
probably. hell forget rebuilding i can buy a new engine for cheaper
than the cost of rebuilding a lyc.

I'm sorry bout the lycoming lawnmower comparison its not exactly true.
the briggs and straton is cheaper to repair. hehe JUST KIDDING.

the simple truth is I feel more comfortable with an auto engine. There
has not been 1 airplane mechanic i've spoken too that has said any
airplane piston engine is more reliable than a car engine. NOT ONE and
i've spoken to atleast 2 dozen of them since before i got my license.
that is not saying the car engine would be just as reliable in a plane
its just saying in their respective environments the airplane engine
has NOT shown any more reliability than the auto engine. also a few of
the mechanics stated they may be less reliable. NOT TROLLING THAT IS
WHAT THEY SAID

now 1 thing i would have u know I'm not a troll i'm not trying ****
anyone off just want ideas.

I want to know WHY an engine with nice rubber motormounts, tranny with
poly bushings between the tranny and SHORT drive shaft connected to a
thrustbearing secured to the frame would not live.

i'll state the conditions more clearly.


Of course you could work on a Lycoming. There's no high magic, you
need a few tools like cylinder base wrenches and so forth, but if you
have the brains to work on any engine you can work on a Lyc, a Ranger,
a Menasco, a Napier Lion, an OXX-6, or any other museum piece.

All these engines have a place, like antique airplane fly-ins and,
umm, museums. (The last running Napier Lion is in a car. Go figure.)

First off though, you haven't done your homework. You didn't study the
available literature, and the successful projects that have flown.

Second, you should build an existing design first with an existing
engine setup. Several are available in varying states of compleness.
After you succeed at that, the piece de resistance can come later.

Third, you have a few Olde Pharts here. Some of them have advanced WSE
and some have apparently died, like Backdoor BoB, or whatever his name
was.

Second,
