Well seems the activituy here has dropped off since all the "wickis" and other

one thing that troubles me some. Seems like every time I ask about a real
problem needing input I get maybe 2 replys at best, but if someone puts up a question
about a non issuse like the price of gas, the list is cluttered with replys.
Does this mean that most of the people on the list are just flyers or wanabys,

Hi Folks,
I recently posted a request for info from listers with flying RV7, RV7a, RV9,
RV9a, who had a specific engine/cowl/induction/prop configuration. I received
little in the way of response--probably because the con fig I have is somewhat
unique. I am making another request for data which will apply to a much larger
group.
I am working on a performance issue and would like to have comparative data.
The data, based on some postings by folks who obviously have a much greater
knowledge on engine inductions than do I, will tell us something about the average
efficiency of our induction systems. If I get a good response I will compile
the data and post it to this site -- it would therefore be helpful in evaluating
the performance of our individual systems against a group average.
The sample data should come from either nose gear or tail wheel flying RV 6-7-9s
equiped with Vans cowl and FAB induction system and carburated 0360s or 0320s
running a fixed pitch propeller. You will also need both rpm and mp gages.
The data necessary for the analysis is as follows:
1. mp indicated on engine gage prior to engine start
2. line up on runway prior to t/o and hold brakes, wot, and note mp and static
rpm
3. just at lift off note mp and rpm
4. mp and rpm at 100-400 ft agl.--watch for traffic!!
Please note in your response whether you have the 0360 or 0320 engine and the
type of engine gages (Vans, AF2500, etc)
Your help is greatly appreciated and maybe we can all learn more about the performance
of our RVs.
Please respond to:

Cheers,

More replies to non-issues than real problems? Not unexpected.
Mechanical, structural or building problems often have one or two
right/better answers--very digital, 0 or 1.
An issue of 'the price of gas' is not directly a building issue, but it
is certainly plane/pilot issue, hence fair game. Most of the answers
are, in fact, opinions or thoughts on the matter. There is no digital
answer, this is an analog issue. There is value in wide ranging input
to a policy problem like the price of gas, as there should be. The
input ranges from interesting, to logical, to 'what are they thinking'.
Nonetheless, they all are important to formulation of quality opinions
on an issue, rather than blind allegiance to our preconceived notions
that may have been formed based on limited, or faulty, information.
I view this forum as an educational tool, not just a builder assist
program, though I'm sure other's hold well-owned opinions to the
contrary. (See, you just had to suffer through another point of view!)

Ok, I've got the tip tanks installed and flying. What I'm finding is
that I'm overflowing the main tank vents (Van's standard main tank vent
implementation) in flight when all tanks have been filled. I confirmed
that the tip tanks can flow fuel to partially filled main tanks OK. But
when all the tanks were filled, gas poured out the main tank vents while
in flight (actually emptied both tip tanks...). Blue stains all over the
belly of the plane, and obvious gas smell while in flight (probably
coming in through the flap extension holes....).
The main tank vents have 45* bevels facing into the airflow (towards
the front of the plane, per Van's plans). They are located just behind
the firewall (per Van's plans). The tip tanks have the 1/4" tube vent
bent into the airflow.
I've installed 1/4" tubing extending 2" down from the belly of the
plane and bent 90* into the airflow on the main tank vents. That has
stopped the main tank venting (when all tanks have been filled) while in
flight. But it now appears that the fuel is not moving from the tip
tanks to the main tanks while in flight (when I inspected the main tanks
level on the ground, both were down about 2" - both tanks had been
selected individually while in flight - and the tip tanks were not down
significantly).
This problem seems to be a mis-balancing of the vent pressures between
the tip tank and the main tank. It makes me question why there shouldn't
be just one vent for BOTH the main and tip tank on each side.... Has
anyone had to resort to this technique?
Has anybody else had this problem? Is so, what was your solution?
I'll be at Sun 'N Fun on 4/7 - 4/8 but will be commuting back and
forth to the Daytona area each day. I'd like to compare notes with
anyone that has tip tanks installed....

Fred,
Are you using check valves to prevent the fuel from going from the mains to
the tips? If not, the single vent scenario would work for you - otherwise
you could pressurize the mains if your only vent was in the tips.
I've been fretting this scenario too - my initial thoughts were to use just
enough of a vent to the mains to prevent the outflowing that you are
experiencing. I also have my plumbing with a slight incline upward to my
check valve so it is the high point in that part of the system. I'll need
pressure to get the fuel to go from the tips to the mains.
Don't know if it works yet....I'm just getting started on firewall foreward.

Jay:
I have the DigiFlight IIVS with GPSS and would never leave home without it.
I had about 500 hours in various RVs before installing the Tru Trak and I am
100% convinced that it is indispensable for XC flying in these aircraft.
Your fatigue level is immeasurably reduced and it allows you time to scan
for traffic and easily handle other cockpit chores. I have flown my Tru
Trak in severe turbulence and it handles such conditions as good as the
zillion dollar auto flight system in the B757 I fly for work. It tracks a
GPS course easily within .07 of a NM. Save up and buy one!!!! BUT.... You
might also hold off and see what Tru Trak is coming up with this summer.
Rumors are they will announce a newly designed EFIS system that will be
revolutionary.

I bought one of the original Digitrak APs and upgraded to the
Pictorial Pilot in my RV6 and the product and factory support is the
best I have ever seen in my 66 years on any product. It works better
than the several certified APs I have flown in the past and we have a
couple of other RVs at this airport with Trutrak APs and they are very
satisfied with them. I drive mine with a Garmin 196 and it works
perfect.

I've installed the check valves per the plans from Jon. I'm thinking
now that taking the check valve out (&replacing it with a union),
capping off the original main tank vent, and only using the tip tank
vent for both tip and main tanks.
The problem with the dual vent method (Jon's approach) is one of
balancing the pressure equally on both vents. If the main vent pressure
is higher than the tip tank vent pressure, the tip tanks won't drain
properly in flight. If the main tank vent pressure is less than the tip
tank vent pressure (by at least the "head" within the main tank vent
line rise) then the tip tank vent pressure pushes the fuel out the main
tank vent (and once it starts, a siphoning action will maintain the
flow).... Evidently, that is a valid possibility as I lost 18 gals of
fuel from the tip tanks out the main tank vents within a 20 minute
flight. The belly of the plane was quite "blue".....
If the tip tank is the ONLY vent for both main & tip tank (by
replacing the check valve with a union), the fuel would run freely to
the main tank (but at some reduced flow rate). Any excess pressure
buildup in the main (while on a hot ramp, or a slip condition in flight,
or an uneven parking condition) would push fuel outwards to the tip
tank. I guess there would be a possibility of not being able to get the
fuel back into the main tank as quickly as it is needed when the main
tank was near empty. That might lead to a fuel starvation issue. I would
think that this would not happen in straight & level flight, only under
abnormal conditions. Would the behavior of this type of fuel system be
acceptable for all realms of normal utility class flight? Big
question..... that can only be resolved through testing or others
experiences.....Would parking on a slanted ramp (where the tip was lower
than the main) move all the fuel to the tip, and could that lead to a
fuel starvation issue if one were to take off with that low tank
selected? Probably.... Is it a real threat (because the highest level
tank should have been selected prior to takeoff...)? Good
questions....(are these "real" safety issues????)
As long as the main tank and tip tank are separated with a check
valve, the main tank requires a vent. Otherwise, it would not have a
method to vent excessive pressures while sitting on a hot ramp.
Jon eluded to the use of an electric solenoid in his plans (but warned
that it's use would cause slower fuel transfers). This would also be a
doable solution, but changes the overall timing of fuel transfer.
Instead of emptying the tip tanks first, the mains would have to be run
down to a level where they would accept the full tip tank quantity. Tip
tank vent pressure would definitely have to be higher than the main tank
vent pressure, otherwise, the tips would never empty.
I'm also exploring the idea of BOTH tanks being vented to the SAME
vent. There are two possible solutions, both requiring another 1/4"
vent line in the wings. The main tanks could be vented to the tips (is
this any different than removing the check valve??) or the tip tanks
could be vented to the existing main tank vent..
I guess this is why I've asked the question as to how successful
others have been with this installation.....Have there been any fuel
problems in any other installations? Has anyone really looked at the
problem?
I sure wish that Jon was monitoring this list.... Maybe he could
comment on how his system should work....
I'm not sure what I'm going to try next. Right now, with the main tank
vent pressure greater than the tip tank vent pressure, I'm not loosing
any fuel. The tip tanks are not usable in flight, but will drain into
the mains once on the ground.

I'm still trying to decide how to set up my aux tanks, so I can't offer
any ideas I've tested. Having said that, here are some thoughts.
I'm not fond of using only gravity feed for the aux because with my
leading edge tanks, the aux won't drain completely until the mains are
down to maybe 5 gallons. I want the aux tanks empty early, rather than
late in the flight to get back to 'normal' handling as soon as possible.
Your tip tanks may empty earlier, with more fall to the mains.
Some ultralite guys have had success by plumbing their mains vent
directly to the aux feed & using the aux vent as the only vent for the
entire 'system'. (You could achieve the same effect by simply sealing
the mains vent.) The mains then suck the aux tanks dry while still
almost full. Obviously, the filler cap needs to seal air tight for this
to work. This idea is tempting, but I hate to change anything on the
original vent/flow path as designed into the plane if I don't have to.
Highest on my list at the moment is to feed the aux tanks to a 2nd Van's
type selector, which would feed the unused port on the existing
selector. It sounds more complex at 1st, but has the advantage of
leaving everything in the original design totally stock except the plug
in that last port of the original valve. It might (emphasize *might*) be
possible to eliminate the 2nd selector by feeding both aux tanks to a
small sump in the belly to feed the original selector. The sump *might*
keep the engine from sucking air when (not if) one aux tank empties
faster than the other. Hopefully, this potential problem would only be
encountered at altitude in cruise flight & recovery would be quick &
only mildly upholstery-pinching.
Email me off list if you're interested & my description leaves some
holes that need filling.

Jay,
Buy it. The best experimental ap out there. It flawlessly tracks a heading or
GPS flight plan. Factory support is excellent.

Louis:
There are 3 major airports in the vicinity but only one that is
builder-friendly. Marana airport (previously Avra Valley) doesn't allow
any one doing contruction or repairs in their hangar period. Tucson
International (TUS class C) has lots of existing home-builts but has
newly announced a policy of only preventive maintenance being performed
in hangars. For the moment they are not enforcing this, but it is the
official policy. Ryan field west of town (RYN) is very builder
friendly. I just lucked into sharing a hangar with another homebuilder
at Ryan.
Hangars are very hard to find in Tucson. All 3 airports have some
new hangars coming on line but they're being offered with extremely bad
terms. The hangar owners want to "sell" them not rent them. The up
front price is > $80,000 plus a monthly fee. The monthly fee at the TUS
group is $200, which is nuts. After 30 yrs, the ownership reverts to
the airport. One group of sane people at Ryan are planning to build
more hangars, but warn that skyrocketting construction costs will push
the rent up to about $450/mo. Although, that is a hangar big enough for
2 RVs. Needless to say, Marana has hangars available because nobody
wants to rent there. There are reasonable deals ($200 - $300/mo) at
Ryan and TUS, but there is a long waiting list for them. I am currently
no. 15 on the Ryan list and no. 6 on the TUS list. At ryan call Bill
McLearran at Mobile Aire Hangars 520-883-5851. (Bill's got an RV-4, so
he knows what you're talking about.)

Those guys who are selling the tubular aux tanks plumb the aux tanks
through facet fuel pumps which act as check valves. When you've burned
enough out of the main, you refill it from the aux using the electric
pump which has a light that comes on after a set amount of time to
remind you to turn it off. Just another idea.

I'm still trying to decide how to set up my aux tanks, so I can't offer
any ideas I've tested. Having said that, here are some thoughts.
I'm not fond of using only gravity feed for the aux because with my
leading edge tanks, the aux won't drain completely until the mains are
down to maybe 5 gallons. I want the aux tanks empty early, rather than
late in the flight to get back to 'normal' handling as soon as possible.
Your tip tanks may empty earlier, with more fall to the mains.
Some ultralite guys have had success by plumbing their mains vent
directly to the aux feed & using the aux vent as the only vent for the
entire 'system'. (You could achieve the same effect by simply sealing
the mains vent.) The mains then suck the aux tanks dry while still
almost full. Obviously, the filler cap needs to seal air tight for this
to work. This idea is tempting, but I hate to change anything on the
original vent/flow path as designed into the plane if I don't have to.
Highest on my list at the moment is to feed the aux tanks to a 2nd Van's
type selector, which would feed the unused port on the existing
selector. It sounds more complex at 1st, but has the advantage of
leaving everything in the original design totally stock except the plug
in that last port of the original valve. It might (emphasize *might*) be
possible to eliminate the 2nd selector by feeding both aux tanks to a
small sump in the belly to feed the original selector. The sump *might*
keep the engine from sucking air when (not if) one aux tank empties
faster than the other. Hopefully, this potential problem would only be
encountered at altitude in cruise flight & recovery would be quick &
only mildly upholstery-pinching.
Email me off list if you're interested & my description leaves some
holes that need filling.

Any airport that accepts federal funds will have a hard time preventing you
from doing any routine maintenance on your aircraft in your own hangar. They
can stop you from starting a business, but not working on your own airplane.
Talk to the EAA or AOPA about it.
