Subject: | Re: RV8A Building Question |
I also bought a partially completed kit but had the help of the previous
builder to get me started and on track.
I would ask some other builders to look at what you have and where you
are and give you some guidance. There are some tasks the are sequential
but many stand on there own as a sub assembly or task. The builders
manual is no detailed. I refer to the plans for most information. Both
the manual and/or plans will have references to the plane you're not
building 8 or 8A and that's a little confusing at first. I went through
a put a X through pages / sections that didn't apply to me.
The Ornduff videos http://www.fly-gbi.com/ were a big help to me too.
Find a buddy that's built one!
Good Luck,
Bob Christensen - RV-8 - N83RC about ready for paint!

Subject: RV8-List: RV8A Building Question
Dear Listers ...
I bought a partially complete kit. The building manual was not all
there
and I'm, therefore, not sure which step to begin next. There are
several
places where rivets are not installed (pending steps to take, in
sequence
I'm sure).
I would like to learn from this vast group of builders:
What should I do to make sure I begin at the next step to keep the
sequence
of steps in order? It wouldn't be smart to get to a place then find
several
rivets need drilled-out to install something else.
I don't mind buying a new build manual if that's called for, or
replacing
missing prints.
What would you gents do in this case?
Many thank for your answers ...

JERRY:
BEST ADVICE I CAN GIVE YOU IS BUY THE MANUAL AND DRAWINGS. DO LOTS OF
READING AND STUDY THE DRAWINGS CAREFULLY BEFORE YOU GET GOING. IT'LL BE
TIME WELL SPENT.

Subject: | Re: RV8A Building Question |
Jerry,
I concur. Buy the manual. If nothing more, it provides you information
and some semblance of order. I did not follow the manual exactly because I
had a QB, but it was somewhat helpful.
You can see much of my building process in what my brother calls the dead
sea scrolls on my web site at _www.rv-8a.net_ (http://www.rv-8a.net) . You
can also review problems discovered post flying that can be avoided if
realized during the building process. I am solving some problems as I do my
first annual condition inspection that could have been avoided.
Regards,
Stan Sutterfield

Subject: | Re: Replacing Fuel Level Senders |
Dan,
I am approaching 2000 hours on my RV8 equiped with the E I fuel gauge and
flat plate sensors inside of the fuel tanks. They are accurate within 1
gallon at any quantity between 2 and 40 gallons. Also when fuel level is
low, they start to flash as a warning.
Good luck

Are the flatplate probes installable as a retro fit or do you have to install them
during construction of the tank?

I don't think it could be done without taking the back baffle off.

Matt -
You could install Van's capacitive plates by cutting access panels in the
rear baffle. Make parts similar to T-407 and T-408 (but without the extra
holes) to close the rear baffle. Or simply Proseal and pop-rivet a patch
over the holes you make.

BRIAN:
THE FLAT PLATE CAPACITIVE PROBES HAVE TO BE INSTALLED DURING CONSTRUCTION OF
THE TANKS. THERE IS NO PRACTICAL WAY TO RETROFIT THEM AFTER THE TANKS ARE
FINISHED. YOU'D HAVE TO REMOVE THE BACK OF THE TANK.
I'VE DECIDED TO SOLVE MY FUEL GAUGE ISSUE BY INSTALLING AN EI FUEL GAUGE ON
THE PANEL AND VANS CONVERTER UNITS UNDER THE FLOOR BOARDS. OTHER BUILDERS
REPORT GOOD RESULTS WITH THAT SETUP. (I HAVE VANS CAPACITIVE PLATES IN THE
TANKS, PRINCETON CONVERTER UNITS UNDER THE FLOOR, A GRT EIS BOX AND GRT
DISPLAY UNITS. THE GRT SETUP IS GREAT, BUT THAT COMBINATION FOR FUEL
MEASUREMENT PURPOSES IS USELESS.
