Matt,
I would find someone with a QB 8 that has yet to install his S&W Floats and use
his tanks to set up your floats.
Then just transfer them to your tanks. That would minimize the down time and could
be done with the wings installed.
Good Luck,
Mike Cingari

Hi Matt,
I have the QB-8 wings/tanks without floats right here in Livermore. I would
be happy to offer any assistance.

Matt,
I would find someone with a QB 8 that has yet to install his S&W Floats and
use his tanks to set up your floats.
Then just transfer them to your tanks. That would minimize the down time and
could be done with the wings installed.
Good Luck,
Mike Cingari

Matt,
Sorry to hear about your fuel level sender problems, but glad you're
finally able to enjoy some time with air under the tires. I know it
would be a little bit of a hike just for breakfast, but would like to
see you at Grants Pass, OR for our EAA Chapter 725 AirEventure on June
26. A beautiful area for flying, friendly people, good food, and
(should be) tons of RV's. What's not to like. Hope you can make it.
Everyone else in range also. Y'all come.
Stan Loer
RV-8 QB in process

By the time you went to all that hassle, you could have just removed
yours and insalled them. It really isn't that big of a deal!!! I'd
even venture to say you could remove your tanks and do it right faster
than working on your back with angle tools......

-----Dear Fellow RV Builders and Flyers, as my RV-8a gets closer to flying
I'm looking at myself in prep to flying her. Presently I fly a LSA I buil
t over 5 years ago and though I have maintained my Class II Med it's getti
ng about time for a new physical. Issue is I have recently developed hypot
hyroidism and take a little blue pill each day to get my "T" level up. I
understand I can fly with it, but that my Flight Doctor has to send cert
ain documents and test results to FAA for a variant. Who has had this, wha
t is the drill and what test results do I need to bring to my Flight Dr.
at the time of the physical in order to expedite the approval? Best regar
ds, Bill

| Subject: | Re: Fuel Both Selector |
Terry,
I've had no airborne problems using a both position on my RV-8A. The
tanks feed evenly. I occasionally feed slightly more from the right tank than
the left and I believe that is due to flying with the ball out of center.
I'm going to do skidding flight tests to verify that theory.
On the ground, if the selector is left in both, the tanks will feed from
fullest tank to emptiest until they are equal.
When building, the cost of the fuel selector was the same with or without
both position. I decided I could always fall back to using Left-Right if
the both selection did not work well. It does work well.
Regards,
Stan Sutterfield
Isn't there a cross-feed problem with a 'both' fuel selector on a low wing
plane like an RV? Did you find a way to deal with that?

| Subject: | Re: fuel selector-(both) |
Gordon,
Thanks for your RV-4 info.
I have 84 hours and I'm doing my first annual condition inspection and I
have had no significant problems with the both fuel selection on my RV-8A.
The right wing will feed slightly more than the left, but that is likely
due to a slight skid. I have burned the tanks down to 4.5 G remaining
overhead my airport. Remaining was 2.9 in the left tank and 1.6 in the right.
Further, I have run one tank dry on the ground in both position (engine
faltered as it began to draw air from empty tank) and switched to the left tank
(which still had fuel) and the engine kept running.
I have had no indications of vented fuel at either the tank lid or the fuel
vents.
So, my confidence level is high regarding use of the both selection on my
RV-8A. It is a pleasure not having to constantly worry about switching
tanks.
I intend to do skidding flight tests (flying most of a flight in an
intentional skid) to evaluate tank feed.
If I discover a significant problem in the suture related to the both
position, I can always fall back to using Left-Right like other RVs.
During the building process, I took special care to make the feed lines
from each tank the same length and using the same degrees of total bends (no
small feat) in order to ensure there was no imbalance caused by higher
viscosity on one side. With a RV-6/7/9, the fuel lines are already even from
both sides so that problem is resolved.
Regards,
Stan Sutterfield

Stan: You may be fine with a "both" position but my experience with the
RV-4 was not. If you haven't already, I suggest an in flight test. With
the -4 I found that fuel would flow from the dominant tank to the other and
when it (the other) was full, fuel went overboard. The transfer was rapid
enough that ~4 gal was transferred in about 15 minutes. Fuel can emerge
from the cap, flow to the flap gap and then flow inboard to the
wing/fuselage gap.

If a tank runs low enough that it will suck air, that's what you get,
air. No matter how much fuel is in the other tank( s ), unless gravity
is helpin' out.

| Subject: | RV-8 - Watsonville For Dinner... |
It was such a nice evening, I just couldn't not take a flight in the RV-8 after
work. I decided to head over to Watsonville and try out the restaurant that
I'd found there on the last visit. Now, it is widely known that I do not care
that much for Mexican Food that doesn't from a Taco Bell -- more accurately put,
it doesn't like me -- but since that's what was at the available fair at this
establishment, I decided to give it a try -- sort of. I had a nice plate
of "jumbo" coconut shrimp that were surprisingly tasty.
Of particular significance on this trip, however, was some Top Speed testing I
did on the way home. At 2500 feet, 2700 RPM, 27.5 Inches of MP, and 1379 F
on the hottest EGT, I was getting -- are you ready for this -- 227 MPH TRUE airspeed!
At 2500 feet that seemed heck of fast! Sweet! The only downside to
227 MPH? 16.9 GPH fuel flow! Yikes!
