[rebel-builders] Rebel - Fuel Tank

Post by Bob Patterson » Sun Feb 19, 2012 11:38 am

Hi Tim !

Great to hear that you are on the way !! Doing 2 tables is a good
idea - several have done that. Try to store the windshield upright,
with no loads on it .... in a safe place !

Since you start with the tail feathers, good to read up on the
latest mods there - doubler & extra tab on elevator end ribs,
doubler under skin on ends of elevators .... (probably wouldn't
hurst to do these on rudder too, although not so critical)
Doubled elev. trim horn ... That's all that leaps to mind...
Measure 4 or 5 times before cutting the elevator trim tab -
cut between rivet holes ... allow room for the hinge ---
--- sounds simple AFTER ! ;-)

As for that extra fuel outlet at the front - it could un-port
in a steep climb ! More trouble than it might be worth !!
I've done some VERY steep approaches in test flying variations
of the Rebel (& Elite) with much more flap than standard
(testing only - DO NOT TRY THIS AT HOME !! ) -
sometimes with VERY little fuel on one side - for testing and
modification purposes -- and I've NEVER had a problem
with fuel flow. Even deliberately ran 1 tank dry - on
several occasions -- again, no problems ! There are more
real things to devote energy to !!

More important to be sure the gas caps & filler necks
are drilled for proper venting, and the cross-vent tube is
in place.

As in any aircraft - the best way to avoid these worries
is NEVER to run around with only 3 gallons in the tank !!
Anything that increases the risk of running out of fuel is
not good .... you wouldn't have to worry about un-porting
if you weren't already taking a big chance by running low !

It usually takes 3 things in sequence to produce an accident -
running low on fuel is right up there as one of the most common !

It's just as easy to run on the top half of the tank ... ;-)

Hello, All
First a brief update on my status as a Rebel Builder. I have received a
windshield, and have had contact with the factory as it seems that they are
in the process of totaling the bill and getting the box filled with the kit
for shipping. I would expect that come sometime late Feb I will have a kit
and will start bugging all of you experienced builders about the standard
problems. I have been reading this group for about 9 months, now, and I have
tried to keep notes about the issues that most builders have. I guess we
will just have to wait and see how construction goes.
I have re-designed the table recommended by Murphy a bit. I have (will) make
it in two separate tables each 48 x 96. That way, when I am done I can take
it apart and have two work benches/tables instead of one long one. Plus I
have decided to make the table top at 37 inches from the floor. This may be
too tall for working on the Fuselage, but it would seem to be better to have
it taller when working on everything else. When I get to the fuselage if I
feel that the table is too tall, I will cut the legs off 6 inches or so.

Now I have a question for the collective experience out there. Charlie
Eubanks introduced it, and so far no one has offered an opinion about it.

Here are his words..
My previous project was a Glastar and because of its folding wing feature it
only has one fuel outlet per wing tank. The fuel capacity was 33 Gal. with
only 27 Gal. useable. In a descending glide with only 3 Gal's remaining in
each tank the fuel lines could un-port long enough to create temporary
fuel
starvation. This problem finally became un-acceptable and Glastar's
solution
was to add a small vented header tank in series and just down stream of
each
wing tank. The header tank had sufficient fuel capacity to keep the engine
running until the nose was raised and the port would close and
re-establish
fuel supply.



Since the Rebel also has only one fuel outlet port per tank, I wondered if
anyone has ever had a similar problem? If so what was the solution?
Any thought anyone? It would seem that adding a additional fuel port more
towards the front of the tank could provide a fuel supply in the case of a
nose low decent with low fuel.
Is there room in the wing root area to do this?

Thanks.
