As i stated earlier i'm an engineer and building/designing things is
something i burn to do. I've given myself 10 years to buid this thing.
My problem with airplane engines is cost they are far to costly for
what u get and are about as reliable as my lawnmower.

the tranny i'm talking bout is a chevy tremec tranny built for the
corvette. looking at the specs its about as bullet proof a gearbox as
anything i've ever seen.

now the tranny things is just an idea, use cheverolets billion dollars
of research to get something going. the only semi-const is the engine
which will more than likely be an ls2 as the ls7 i originally wanted is
up there with airplane engines in cost. well lower end airplane
engines. prob by the time i need the drivetrain it'll be cheaper.

the question is if the engine/tranny is isolated from the
thrust/sideloading/vib of the prop and besides weight would it be
reasonable to assume this would be okay. it really shouldn't be all
that difficult to completely isolate the drivetrain from the prop.


now some other details that i would like to get input on:

now the craft is essentially a kevlar covered steel tube frame. reason
being i'm good at welding but have worked very little with composites(
built speaker enclosures and spoilers for my car). but i really like
the finish of the composite aircraft. and kevlar because its cheaper
than graphite and lighter than fiberglass.

1. i only intend to run this thing at approx 50% power while i could
spin it up higher i just can't see a reason to do it. 400lbs for
200+hp seems like a good trade to me. Plus i can buy another one or
rebuild it myself for far less than the rebuild of an aircraft engine.

2. I"m not trying to build the most efficient fastest cruising thing
in the world. i want something reliable, simple kinda speedy(150 -
160kts) and without the prop, massive front end and massive instrument
panel infront of me.


3. 2 seater also maybe 3 but most likely 2.

4. also what is a good way to keep the sound of the engine/prop/gears
in back where it belongs ? massive noise in the cabin would completely
ruin the effect i'm trying to achieve.

hey guys i'm only hunting for ideas now so please feel free to respond
with anything u can come up with pro/con.

also hopefully you aren't annoyed hehe cause prob get realy frustrated
when i start asking about wing construction hehe.
