No check valve.) flow to the tip tanks can be some what mitigated by the position of the inlet to the main tank (from the tip tank). Jon's plans call for this fitting to be in the center of the tank height. This results in there always being fuel in the main tank, and the inability to drain to the tip tank once the main tank level goes below the level of this fitting. This is something like 10 gals of fuel. It also takes a fair amount of time for the tip tanks to refill, and the aircraft must be in an abnormal position (wing low on a ramp, or a continuous slip) for that time period to have a substantial amount of fuel drain out of the main. In flight, if the low wing were selected, you would also run the risk of un-porting the fuel pickup before a substantial amount of fuel were moved (but this is another problem). What I like about this setup is that there in no pilot input required to utilize the tip tank fuel: no fuel selector to forget to position, no electric pump or solenoid to forget to shutoff.. If there is fuel in the tip tank, then the main tank is always full. I'm in the process of trying this setup out. I'll post to the list the results of my tests. I should have it completed for the trip to Sun 'N Fun next week (4/6 - 4/7 for me...). Time: 06:43:00 PM PST US From: "Bob Barrow" < bobbarrow10@hotmail.com > Subject: Tip tanks (more) --> RV-List message posted by: "Bob Barrow" < bobbarrow10@hotmail.com > I also plan on using tip tanks on my RV7A. And I've also been pondering this fuel feed question for at least 12 months. This is a very good thread and timely for me. I've seen many solutions (actually flying) for feeding fuel from the tips and I've listed a few below with a few of my comments on each. Just my opinion of course and I welcome further feedback. 1. Floating "cistern" style valve in main tank. Opens valve to allow fuel to flow from tip to main when fuel in main gets down to a certain level. Advantages: Fully automatic..nothing to do or remember. No chance of fuel being vented from mains vent. Disadvantages: No suitable valve available on the market as far as I know which means you have to manufacture it. May be prone to mechanical failure. A nightmare to get to if it fails. Conclusion: Not for me. 2. Five way fuel selector. Andair sells them. Enables selection of either mains or either tips individually. Advantages: 100% access to auxiliary fuel guaranteed. No check valves to fail. No problems with differential vent pressures between mains and tips. Disadvantages: You'll have to run the tips dry to empty them which means the engine will stop. If you're not careful and you leave the tips selected you might lose engine power at a bad time. Conclusion: A potentially dangerous set-up if you get distracted. Using all useable fuel in flight essentially means running a tank dry. Not for me. 3. One way mechanical valve. Andair sells them and they are fitted between the tips and the mains. Advantages: Very reliable in terms of fuel availability and nothing to remember. Disadvantages: Can result in fuel overflowing through mains vent if pressure differential not precise. Once flow starts it may be assisted by siphon effect. When the plane is parked with full mains, fuel will seep back through the one-way valve and refill the tips. This can be a problem for accurate fuel measurement. It also precludes any aerobatics until the fuel can be pumped back into the mains in flight. Also requires a well sealing fuel cap to prevent fuel loss at the cap (that excludes Vans caps which are terrible). Conclusion: Popular solution but not without problems. 4. Electric fuel pump between tips and mains. Advantages: Fast fuel transfer. Control of flow. Disadvantages: Requires electric power to gain access to aux fuel. The pump introduces another failure point. If the mains are full when the pump is switched on then all the tip fuel will be pumped overboard. Conclusion: Unnecessarily complicated. 5. Straight feed between tips and mains. No check valve. Advantages: Completely outweighed by disadvantages. Disadvantages: No way to control fuel from feeding back into the tips while parked or in flight. If it occurs in flight it could result in fuel exhaustion. It could also result in an irretrievable spin if aerobatics attempted. Conclusion: Not practical as far as I can see. 6. Tips to mains through fuel selector. Calls for routing the tips fuel into the cabin to auxiliary selector(s) and then to the mains. Advantages: Virtually guaranteed fuel supply if correct selection made. Disadvantages: Additional fuel plumbing in wing and cabin. Additional fuel selectors which may present problems in terms of location, access and accidental movement of selector by pilot or passenger. Conclusion: Messy plumbing in cabin and fuel selectors everywhere. 7. One way electric solenoid. Fitted between tips and mains. Advantages: Complete control of fuel flow. Fuel can be retained in tips until mains reduced to avoid any possibility of fuel overflowing from mains vent or leaking fuel cap. Positive valve action will prevent fuel seeping back into the tips while plane parked. Disadvantages: Requires electric power to enable access to aux fuel. Relatively slow fuel transfer (but should exceed fuel flow required for 100% engine power). Conclusion: Not perfect, but might be best of the bunch. Have others had success with an electric solenoid. If so, what type of solenoid did you use. If you've had problems with this arrangement I'd like to know about that as well. careerone.com.au ________________________________ Message 4 _____________________________________ Time: 07:04:19 AM PST US From: "Evan and Megan Johnson" Subject: Re: RV-List: Re: Moving to Tucson-need advice --> RV-List message posted by: "Evan and Megan Johnson" My brother Dominic Johnson is a real estate agent in Sahuarita and he sent me a listing for a lot at this strip.

Last time I talked with my insurance contacts the insurance carriers that he knew of, were requiring the total destruction on the aircraft that were totaled because of water emersion and lack to treatment after they were pulled from the flood. The salvage yard had to crush them with a bulldozer and certify that all parts would never be in the stream of commerce again. What a waste.

So I called the manufacturer and discussed the problem with Paul Brewington. He ask me to mail my unit to him and he would try to fix it. Well Paul not only fixed the timer in an expedited matter he even returned my cash I had enclosed for his trouble and the return postage. YES, there are still good vendors our there.

I actually received quite a lot of replies to my post but for some reason people chose to email me directly. I appreciated all of the comments but I would ask people to respond through this forum because it enables everyone to gain benefit from the diversity of opinion and experience. In terms of your specific direction re straight feed. There are a number of reasons I feel reluctant to go that way but I will raise just one. The ability of the RV to recover from a spin depends primarily on the capacity of the rudders' authority to overcome the moment of the spinning wings. And because moment is lever arm multiplied by mass it therefore stand to reason that even a small increase in mass at the wing tips will grossly increase the moment. For a start all tip tanks will add at least 6 lbs over the weight of standard tips (dry weight). That alone may influence spin recovery. Any additional mass in the form of fuel in the tips (extra 1kg per litre approx) could prove fatal in a spin....even a very small quantity (say just 3 or 4 litres) may lead to an unrecoverable spin. On the other hand it may not...it might take 10 litres...but I for one will not be the test pilot finding out where the limit is. So I would say that it would be very prudent not to get into a spin with any fuel whatsoever in the tips. And the straight feed solution can never guarantee that the tips are completely empty. So aerobatics would be out of the question...firstly because they would guarantee that fuel would run to the tips...and secondly because it greatly increases the chances of an inadvertent spin. As Einstein was reported to have said: " A mechanism should be as simple as practicable...but no simpler" (or words to that effect). In aviation oversimplification can introduce risk...just look at Van's nose gear. >From: "Stucklen, Frederic W UTPWR" >To: "'Bob Barrow'" >CC: "'RV-List'" >Subject: Re: RV-List: Tip tanks (more) >Date: Tue, 28 Mar 2006 09:57:00 -0500 > >--> RV-List message posted by: "Stucklen, Frederic W UTPWR" > > >Bob, > > Per your item #5 below, (Straight feed between tips and mains. >No check valve.) flow to the tip tanks can be some what >mitigated by the position of the inlet to the main tank (from the tip >tank).

Target those planes bounced around by high winds, or a tornado. Maybe something crushed by a falling hangar. All I know is that 4 people who I have flown with and who really do own and fly RV's have had tremendous luck with engines from salvage operations.

The problem is that by the time the savlage yard gets it the engine has been seperated from the airframe and you have to take the yards word for the source of the engine. You're better off bidding on the salvage directly with the insurance companies.

Target those planes bounced around by high winds, or a tornado. Maybe something crushed by a falling hangar. All I know is that 4 people who I have flown with and who really do own and fly RV's have had tremendous luck with engines from salvage operations. As with almost every transaction in this life, caveat emptor. And don't think there are no deals out there.

I purchased a hurricane-damaged engine from Wentworth Aircraft last September for my RV-7A with the intention of overauling it. They guaranteed all of the expensive parts (crank, case, etc) to be within serviceable condition. I believe this is true for all of the engines they sell unless they specifically say that a part is bad. Anyway, after dissassembling it and taking it to a machine shop, the crank was found not to be within serviceable limits and the case had a seriously worn down main thrust face - nothing that could be found without dissassembling the engine. After not being able to find a replacement crankshaft, Wentworth refunded my money, and even covered the cost of teardown and inspection - something they were not liable for as their contract states that only the cost of the engine will be refunded in this case. While not being happy about having to find another engine, I was very happy with the way Wentworth handled the situation and would not hesitate to deal with them again on my next project. So I guess the moral of the story is if you are going to buy a salvage engine, get a guarantee or warranty on the major parts, and if you are worried about the source of the engine, ask the salvage yard for the N-number of the aircraft that the engine came off of and contact the owner. I was able to contact the owner who verified the information provided by Wentworth. If they won't give or don't have the N-number, move on.

Are you planning to test spin recovery with the tip tanks installed, but empty, during your test phase? I have a friend with home grown removable tip tanks on his RV4 - he said he removes them before doing any aerobatics. Perhaps this is an option with the Johanson tanks. -- Mickey Coggins http://www.rv8.ch/ #82007 finishing do not archive ________________________________ Message 22 ____________________________________ Time: 09:47:48 PM PST US From: "Terry Watson" Subject: RE: RV-List: Tip tanks (more) --> RV-List message posted by: "Terry Watson" I have Jon Johanson's tip tanks and have been following this discussion with great interest. The change in the spin characteristics, even when empty, does concern me, as does the fuel venting problems already discussed. I haven't installed the tip tanks yet, and I still have the wingtips that came with the kit so I still have options. I would NOT consider Jon's tanks as "removable", although I'm sure some of you could remove and replace them with regular wingtips, including the plumbing and wiring in a few hours if you wanted. It would take me more like a week. It would be helpful to me and others if you would let all of this discussion go to the archives. Thanks for all the great information, guys.
