Fellow RV builders,
We head out today to Oshkosh today and look forward to meeting
you all. We'll be camping with the RV-10 group this year and we'll be
exhibiting in the East Hall, Booth 5016.
Please stop by and see our new products. We will be
introducing two new products to the TCW Technologies offerings.
Come try out the working demos of "Intelligent Power Stabilizer" and
"Intelligent Lighting Controller". A preview of these new products
is now up on our web site. www.tcwtech.com
We also have our working demo of Safety-Trim and Intelligent
Flap Controller for your review.
Best regards,
Bob Newman

Subject: RV-List: Superior vs. Lycoming; XP-400 vs. IO-390
Dear Listers,
What is the common opinion of Superior XP engines vs. the typical Lycoming
engine?
In looking over the Superior web site, they have a new 220hp XP-400 engine
designed around the basic IO-360 Angle Valve chassis that looks pretty nice.
At $30,000 new, its $3-4k cheaper than the Lycoming IO-390 solutions and, if
you believe the Superior mantra, a better designed engine in general.
Matt: A 2.6% increase in displacement yields a 4.8% increase in power? Is
Lycoming stupid? Maybe. Is Superior still in development? Probably. Will
they actually deliver 220? Who knows? A cynic might suspect a bit of
brochursmanship here.

I'm having trouble following this math: "A 2.6% increase in displacement yields
a 4.8% increase in power?"
An increase in displacement from 360 to 390 is an 8.3% increase, while an increase
in power from 200 to 210 is a 5% increase...reasonable in the Lycoming case
if it's true that the IO-360 angle valve doesn't produce a full 200 horsepower
to begin with.
An increase in displacement from 360 to 400 (Superior) is an 11.1% increase, and
an increase in power from 200 to 220 is exactly a 10% increase.

Subject: RE: RV-List: Superior vs. Lycoming; XP-400 vs. IO-390
Gordon's cynicism is entirely understandable, but I'd bet on Superior to
deliver at least 220. I agree that they're probably still in development;
they don't stand still just because they've put a product on the table. I
pondered an XP engine for a long time and watched the product evolve. What
finally got me off the fence was my wife paying for the Build School. I
thought I had read up a lot on the engine and various manufacturer but in
three days I learned a ton. As it happened, the other student (they run two
at a time) had to cancel, so they used the other station to build one of the
Vantage engines. During the build, I got to compare: flat tappet vs.
roller, carb vs. injection, and so on. And I also got shown some of those
improvements over the stock Lycoming, like oiling the thrust bearing face or
the sump improvements (in hot rods, you'd call that porting and polishing).
I also got to see their specifications - the checklist of tolerances that
they use when building. I'd guess that Lycoming uses similar but they are
way tighter than the acceptable tolerances in the Lycoming manuals. And
after my build (which was inspected by their QA staff as I watched) they ran
the thing on a test stand before shipping it to me.
So that's the product; obviously I have a good opinion of it. Now, let me
tell you about the people. I was treated like a VIP there, which you'd
expect. Everyone, from the CEO down knew who I was and took time to say hi
or answer questions. Then I left and got my engine, so you might think that
I'd be forgotten. Not at all. They've answered every question I could ask
about my installation, quickly and helpfully. And I recently stupidly lost
an intake manifold bolt, so I emailed them to order a replacement. Two days
later, I had the replacement plus washer and star washer at no charge. Sure
a minor thing, but I've known other businesses that would charge for the
part and add a handling charge. I like this company. In fact, I asked if
they might do an XPIO-540; I'm considering an RV-10 for a future project.
They don't have one in the works, but they wouldn't rule it out. If I do
and they do, I'll be buying one, you betcha.

Subject: RV-List: Rivet Spacing for Elevator Skin Stiffeners
Greetings:
I have "older" drawings for the RV-8 Elevators. They show NO required rivet spacing
(the number of rivets to be used) for each Elevator Skin Stiffener. Understand
the newer Stiffeners come with pilot holes already prepunched in them
from Vans.
Can someone give me the "number" of rivets used for EACH Stiffener:
E-720G E-720A E-720F
E-720H E-720B
E-720J E-720C
E-720K E-720D
E-720L E-720E
(Using a rivet spacing fan, I can then make the rivet spacing equal for each Stiffener.)
Thanks for your help, Garey Wittich Santa Monica, CA

Garey,
I'd guess that the drawing does show rivet spacing, i.e.: 1 1/4" or 1
1/2" typ. Layout the rivets on each end and use a rivet fan set near the
"typ (ical)" space and when in doubt, err to the side of shorter
spacing. If a spacing is not called on the drawing, measure the rivet X
marks on the drawing and account for the scale. Again, err to the
shorter spacing if it isn't clear.
Pax,

Subject: | A Tough Decision |
After three years building and five years flying my RV-8, I have decided to
move into Light Sport aviation.
I will always cherish the memories of RVs and all they have to offer.
After spending months researching Builder Liability Issues, I have decided
to donate Cappys Toy to an Aviation Museum.
The museum has offered to create an Experimental Aircraft Section featuring
Cappys Toy. It is heartwarming to know Cappys Toy will forevermore be
representing Experimental Aviation, and that I have found a good home for
her.
The museum has agreed to accept Cappys Toy without the engine, engine
accessories, NAV/COM GNC 300XL, transponder GTX 327, autopilot Trio Avionics
EZ Pilot and 5 point airline type seat belts.
The expected delivery date is September 15, 2008.
In addition to a tax deduction, the sale of these items will enable me to
re-coup some of the losses incurred from not selling the airplane outright.
If you are interested in a proven complete functioning power plant package
with less than 450 hours for your project, or any of the other items, please
give me a call.

Fellow aviators:
A few weeks back I loaded a heavy, folding shade tent into the pax seat of
my RV-6A to take to a neighbor's fly-in event, in the process bumping the
tuning knob of my Icom A200 radio and bending its shaft. The radio has
since stopped responding to turning the outer ring (MHz) selector, and needs
repair.
I'm not afraid to try this repair myself if I can get my hands on a
replacement concentric optical shaft encoder that is a proper fit, nor
opposed to sending the radio off for repair by an avionics shop is I can
find a reasonable quote. Menawhile, looking for a loaner radio while I get
the repairs done, or a good deal on a replacement A200 if I decide to swap
first / repair later.
Any help out there?
Thanks,
Bill B/ Stormy

Bill,
Sorry to say, but other than IcomAmerica in Washington, there are no
parts available or a repair station you can send it to for repair. They
won't even send you parts. You have to send it back to them. I've sent
mine in for repair before and I've been advised to take special
precaution with the tuning knobs when shipping as they are some of the
most expensive parts to replace. I'm guessing your quote maybe be up
there along the lines of a new radio. Of course check with them first.
Sorry for the misfortune.
