Rusty - as airplane builders
we all must be eternal optimists. It is great to hear you get back the
spirit. I commend you on sharing both your accomplishments and follies
with us all. I hope you realize that we are all behind you and want
nothing other than total success for your project. It is easy to throw
out terms such as "guinea pig", but truthfully we view you as "the
professor". I hope our encouragement and interest will help you get
through these trials. All of this is so symbolic of life, no? So we
all pick to follow the lemmings, the sheep, or the eagles( we always
say eagles even though the buzzards are incredible fliers, not to
mention the blue herons and pelicans :-))
please note that my -6A uses
a large loop from the gear leg to the caliper, which reduces the
fatigue on this joint. It has worked fine for 1000 hrs. Avoid a
single tight bend, these don't take the flexing without breaking.

[FlyRotary] Life is better at 5 psi
Greetings,
I took the
plane out again today, and found it to be MUCH more satisfying at 5 psi
of boost. I ordered another excellent used 89-91 turbo off Ebay today,
and I'm going to pick up a crack free exhaust manifold to go with it.
Before I install the new turbo, I'll port the crap out of the
wastegate, to see if I can get down to something more reasonable, like
5 psi, rather than 10+ like I get now. If that works, I can actually
use full throttle, which will make me, and Lynn happy (see Lynn, I do
pay attention). I'm also trying to pick up an 87-88 turbo actuator,
which was only 5.5 psi I think.
As I
mentioned before, the new cowl is on order, and I'm starting to work
out the details to get this all inside the stock cowl. I can't imagine
how nice it might fly without all the cowl and tire drag.
Realistically, it will probably be around the first of the year before
this all happens, but at least I'm back on track, and excited about
doing it all. Thanks for putting up with my earlier depression. This
IS going to work, and it IS going to be the hotrod I hoped for.
Cheers,
Rusty
(psyched again)
Hi Rusty,
I am not normally a poster here, but can't resist the temptation to
second Kevin's thoughts on your "sharing both your accomplishments and
follies with us all." I also was glad to see you not abandon the
turbo. Like others may have suggested, I think you are being way too
conservative on your "Max Boost" figures. Unlike intake valves, etc.
... what's to break?
I hope you do not become so sucessful at holding the boost down by
porting or whatever control scheme you end up using, that you lose the
ability to go to a "War Emergency" power setting of "all it will put
out" to help you clear a ridge, or whatever. Needing more power and
not having it available is bad enough, but the thought that it was
there, but you engineered it out in the name of safety, would be hard
to take.
Keep trying. You are inspiring eveyone.
Dale Smith
