    Subject: Request for Info
    --> RV-List message posted by: David Burden <hootsnik@sbcglobal.net> 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: www.hootsnik@sbcglobal.net Cheers, db

    --> RV-List message posted by: "Chuck Jensen" <cjensen@dts9000.com> 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.

    Subject: Tip Tanks
    --> RV-List message posted by: "Fred Stucklen" <wstucklen1@cox.net> 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 Stucklen RV-6A N926RV

    --> RV-List message posted by: "Ralph E. Capen" <recapen@earthlink.net> 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.

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. Doug Weiler N722DW, RV-4

    From: "Fred Stucklen" <wstucklen1@cox.net>
    Subject: Re: Tip Tanks
    --> RV-List message posted by: "Fred Stucklen" <wstucklen1@cox.net> 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. Fred Stucklen RV-6A N926RV 545 Hrs second offender... Subject: Re: Tip Tanks From: Ralph E.

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. Charlie

    Subject: Re: Moving to Tucson-need advice
    --> RV-List message posted by: sarg314 <sarg314@comcast.net> 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.)

    Subject: Tip Tanks
    --> RV-List message posted by: "Ed Holyoke" <bicyclop@pacbell.net> 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'd like to compare notes with >anyone that has tip tanks installed.... > >Fred Stucklen >RV-6A N926RV > 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. Charlie

They can stop you from starting a business, but not working on your own airplane. Talk to the EAA or AOPA about it.
