What a bunch of BS...Can you find the voltage on the battery anywhere?...Then have a look at www.batteries.com and see if they have something that looks like it. For that matter buy any battery of the same voltage and duct tape the thing on the outside of the Narco. What's crazy is, that on Narco's web site, they have full details and instructions on how to open the thing up and specific steps how to change the battery! $200? I think not, for sure! I might be dumb, but Daddy didn't raise no fool! I think a new, less upkeep model is in order for sure. Thanks to all who responded on this topic. Gotta love this site and the members who so graciously give their assistance! Thanks, again!! Rick

The Narco ELT manual says that any other battery may harm the unit. I don't always buy that ploy, but I guess it is possible. I would appreciate any and all valid responses to this quagmire.

    Subject: Re: 701 aileron trim
    --> Zenith-List message posted by: doug kandle <d_kandle@velocitus.net> Personally I would not install an aileron trim. But if you wanted to do such a thing, then I think the kit for the elevator would work. You could mount the hinge on the wing outboard of the fuel tank, not on the aileron. Not having flown much in a 701 (mine is not complete yet), I don't know how stable the plane is in roll. If there isn't enough stabilizing force, then a very small input from a trim device might just start a slow roll. Then you would end up constantly controlling the plane with the trim input rather than the stick. I believe trim devices will only work along a relatively stable axis. Otherwise you need an active device like an auto-pilot. It would be best to hear from someone who as flown a 701 with aileron trim on their plane. I know these planes are called "Experimental", but I don't care to do too much experimenting.

    Subject: Re: 701 aileron trim
    --> Zenith-List message posted by: Paul Mulwitz <p.mulwitz@worldnet.att.net> It seems to me that the logic used here indicates that elevator trim would cause a slow loop. Aileron trim is a new concept to me. I have flown many aircraft with rudder trim which would seem to accomplish much of the same purpose. The Zodiacs offer an aileron trim option which I am installing on my XL. The design had a few flaws which were easily corrected. The "Servo" and indicator used is the same as the elevator trim. I don't see how aileron trim could hurt anything except the airplane cost. If it turns out to not be very useful then it will just sit in the neutral position and do nothing. The issue mentioned most often when I asked about the need for aileron trim has to do with the uneven fuel burn in low wing aircraft. This would not seem to be a problem with the 701, but maybe it would be useful for other issues too. One more issue mentioned is making changes for passenger or no passenger.

    Subject: 601XL Brake Problem
    --> Zenith-List message posted by: JAPhillipsGA@aol.com Dear Thread Friends, anybody out there have significant noise such as rattles, bopping and bumping from the brake calipers when taxiing? The noise stops as the brakes are applied, but returns as the pressure is released. I think I put them together correctly, but as we have all seen, the brakes are sort of poorly explained in the plans. The calipers move quite a bit with the pressure off and can be moved, flip-flop, by hand. I wrote the Grove folks, but have not heard from them yet. Anybody got a diagram that shows which bolts go where, I would appreciate seeing it. Maybe I left out a couple washers or springs or such, Best regards, Bill of Georgia 601XL-3300w/DC 19 Hours

    Subject: Re: 701 aileron trim
    --> Zenith-List message posted by: JAPhillipsGA@aol.com Paul, you really need the aileron trim on the XL. The left side is a bit heavier as I suppose intended to balance when you fly with a passenger. Course, without the right side pax it will fly left wing heavy and if you want to fly without roll pressure you need a trim. Also, as the tanks are used up the balance is effected and the aileron trim makes flying easier. Do what you want, but I am really glad I installed it, Best Regards, Bill

    Subject: Oil leak on Rotax 912
    --> Zenith-List message posted by: Hello list members. I really need your input to a problem I have been having since I first flew my Zenith 701 with a Rotax 912 UL engine. Engine has TT 260 hours. The engine is leaking oil and I have replaced all O rings, replaced the oil return tubes for the valve push rods, removed the oil pump and added some liquid gasket on the outer rims as advised by Lockwood. The O rings on the return tubes are new. Still there seems to be a leak around them. The oil system has been vented according to the manual, and the oil pressure is around 4,7 psi when hot. Oil temps are normal. Here comes the question: Can the oil cause this leak? I am using the Shell Advance Ultra T4 which is a fully synthetic oil. Rotax did reccomend the semi synthetic oil, but it is not available at this time. I know that these synthetic oils are thinner than the regular or semi synthetic oils, so could this be the reason the oil rings are not holding oil with the oil pressure around 5 psi? Hope you can help. I am about to give up on this engine. Best regards, Johann G. Iceland. johann@gi.is

    Subject: Re: 701 aileron trim
    --> Zenith-List message posted by: Hello Larry. I would not worry about installing an aileron trim on your Zenith 701. My plane is very stable in the roll axis and does not need any trim there. I did intall the elevator trim, and highly reccomend that. Makes it much easier to fly when you transfere the fuel from wings to header tank, and if you have a pax on board.

Johann, You mention two possible sources for the oil leak. The oil pump, oil under pressure. The push rod return tubes, return oil under static conditions, crank case pressure. Try to narrow down the leak source. One way is to clean and dry the suspected leak areas, spray them with spray can powder deodorant, or foot spray powder. The powder coating will show up small leak areas. Easier to see, pinpoint the source. Be on the look out for leaks through pours castings, usually leaks under pressure conditions. Take it slow, at first try building up oil pressure by rotating the prop, not by running the engine. The leak should show it self that way too. And there could be leaks from both pressurized and static sources. Don't give up. Jerry If you still suspect the oil being used, change it to try to eliminate it as being the cause.

    Subject: Oil leak on Rotax 912
    --> Zenith-List message posted by: "David Alberti" <daberti@sbcglobal.net> Inverse crankcase pressure is what pushes the oil back to the tank. If you pull one plug from each cylinder and crank the engine using the starter you will build oil pressure very quickly but not crankcase pressure. Make absolutely sure you are not overfilling the engine with oil. The location of the oil tank is quite critical and it's very common for oil to siphon back into the engine when you shut down. Running the engine for a minute will insure all oil is pumped back to the oil tank so you can check the level then to be sure. I run Mobil one XT4 full synthetic for motorcycles. Why would the crankcase build up pressure? The vent tube on the oil tank should eliminate that ????? What type of oil are you using? Thank you, Johann G. Iceland. johann@gi.is

Vented as it is intended to be for the 912 installation, the crank case pressure should be very low, but it is a positive pressure nonetheless. Since you are seeing oil residue on both sides of the engine, low and around the steel mount plates, Re check to be sure the O rings for the push rod tubes are the correct one's. If they are too hard they may not always seal the tubes to the crankcase and heads. Were these seals changed recently? They do move a bit as the engine heats up, and so have to stay seated to keep the seal, and the oil from seeping a bit. Is the leak such that it requires addition of oil after flight? Just how big is it? Has the oil leak been with the engine all along? What has been changed/maintence that may have caused it? Was it there when other oil was used? The oil foaming question. Are the plugs and banjo fitting on the bottom of the crankcase secure and sealed? Keep looking. Sounds like push rod tube seals from your description.

Any leaks might be air leaks, detected by using soapy water brushed or sprayed on. Was this part of the recommended air pressure method?

The leak is such that I need to add oil after about 2-3 hours of flight. Oil spreads under the engine and back to the firewall and under the fuselage. Very messy. Yes, the oil leak has been there since I installed the engine. It was bought used with total of 250 hours. According to the previous owner, the engine was in a Rans 6 which stalled shortly after airborne, and he had a prop strike. The crankshaft was realingned by a professional repair shop in Iceland, and I replaced the piston rings and the O rings and installed the engine in my plane. Everything according to the Zenith manual and Rotax installation procedure. I have been using the two types of oil from day one, from Shell, the Advance VSX 4 10W-40 and the Advance Ultra 4 10W-40. There does not seem to be any leak around the plugs and banjo fitting on the bottom of the crankcase. I will check that tomorrow with the powder method.

    Subject: Re: Oil leak on Rotax 912
    --> Zenith-List message posted by: Jerry, The method is done with oil in the tank filled to the top mark on the dip stick. Your question is very interesting. Since the oil return line is disconnected from the tank, I would assume that the oil is pressed into the crankcase with the pressureized oil tank. But I am not sure. Oil tank is pressurized up to 1 bar. The procedure did call for checking for oil leaks from the engine, so I would guess it should be pressed out from any cracks or leaky o rings. This method is in the service instructions SI-04-1997. on this homepage, http://www.kodiakbs.com/sdintro.htm Thanks again, Johann G. > > In a message dated 10/19/2005 3:49:44 PM Central Daylight Time, > owner-zenith-list-server@matronics.com writes: > .

    Subject: Oil leak on Rotax 912
    --> Zenith-List message posted by: Hello Bill. The rings are new and the cylinders were "honed" prior to the installation, so I would guess the seal is good on the rings. I have removed all the cylinders and checked the rings on all pistons, and everything looks good, with the correct position of the rings. But I do not know for sure. Everything is according to the Rotax manual. Thank you for the help.

    --> Zenith-List message posted by: "DICK WILBERS" <RWILBERS@TAMPABAY.RR.COM> Dear Listers: I seem to remember that some 601 HDS guys moved their radiators for the Stratus engine back on the belly, on the right side if I remember correctly, and lowered the entry end of the radiator 2 or 3 inches. If my memory is correct, I have a couple of questions to ask. Did this improve cooling properties? Was the added drag of lowering the radiator entry detrimental? Your replies will be appreciated. Thanks in advance.....................................................Dick Wilbers

    --> Zenith-List message posted by: Michel Therrien <mtherr@yahoo.com> Aaron, I've built an HD from plans with the old plans. Dimensions, especially skin dimensions are not always right. I learned to cut the pieces oversize, assemble and then to cut them to final size by fit, not by mesurements. For the ailerons, I did not have difficulties. I made the ribs as per the plans. Then I bent the skins, bending test pieces first until I got a shape that fit the ribs.
