Any good pipe thread sealer paste designed for gasoline and metal fittings. Permatex makes some that can be found at most auto parts stores, Sealube is another good one, Aircraft Spruce sells it. Teflon tape is not recommended, it tends to come apart in shreds if the fittings are later removed and the shreds can get into fuel lines and possibly cause problems. Its not easy to clear all the particles of the tape off the old fittings especially on female threads. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru.

There is one more very simple option that can be used for a position indicator for the flap. You can find a cheap float-style fuel level sender with a guage. Just remove the potentiometer with the lever arm to the float and mount it so the lever arm moves with the flap actuator. Then you can set the flaps in various positions and mark the positions on the fuel indicator (change the face on it if you can) . I am not sure that the sender from Ray Allen has enough travel for use with the flaps. Maybe if you mount it lower down on the lever arm of the flap actuator tube it won't have much travel. Just an idea - a really simple one at that. have an excellent Christmas.

I believe wide-open throttle (WOT) conditions make manifold vacuum very unstable, if non-existant; NOT what I would like if I am in the middle of a go-around or a missed approach !! However, if I need to declare an emergency or priority handling because my vacuum pump took early retirement, it's good to have a secondary source of vacuum which, as you pointed out, is not heavy OR expensive. I guess this situation would not work with any engine using Bing carbs, in that there is no mixture control. Should I be rethinking that Jabru? Nope - it's all-electric for me with MAYBE a backup steam gauge or two if I can find them cheep.

Now you could use an electric vacuum pump...heavy and expensive.

It would be my primary system. My engine will be a Corvair, so there's no platform for a vacuum pump. Not sure if I could incorporate manifold vacuum or not....I'm new to this building stuff, so I'm not sure. Good idea though if it would work....any thoughts anyone? Mike F.

I received added info from each of you. I now have choices - that is a good thing. Also, see that Chuck Deiterich made his cowling out of aluminum. That is another alternative. An added thanks for those who might have additional info on the way.

The Gyro would be connected to the accumulator. This would sustain the vacuum when the throttle was opened for short times. The accumulator size depends on the rate of flow into the gyro. I agree, however, with the comments regarding glass panels; meaning no rotating parts and hence no need for a vacuum. If you have the gyro then this vacuum approach makes sense.

Move it up the the flap tube to where your max travel is 1.2". Should work good, that's what I am doing. The Ray Allen sensor is $30.

You can find a cheap float-style fuel level sender with a guage. Just remove the potentiometer with the lever arm to the float and mount it so the lever arm moves with the flap actuator. Then you can set the flaps in various positions and mark the positions on the fuel indicator (change the face on it if you can) . I am not sure that the sender from Ray Allen has enough travel for use with the flaps. Maybe if you mount it lower down on the lever arm of the flap actuator tube it won't have much travel. Just an idea - a really simple one at that. have an excellent Christmas. > David > > "Beckman, Rick" wrote: > --> Zenith-List message posted by: "Beckman, Rick" > > > A big THANK YOU to Gary, Tracy, Scott and George for info and ideas > on the flap actuator question!! > > God > Bless!! and Happy Holidays!! > > Rick > > > David Barth > 601 XL Plansbuilder 15% done? > Working on Wings > www.ch601.org > > --------------------------------- > > ________________________________ Message 30 ____________________________________ Time: 07:04:52 PM PST US From: "Larry Martin" Subject: Re: Zenith-List: Feul resistant sealer? --> Zenith-List message posted by: "Larry Martin" You need to do a leak check before you nail the top down.

The Gyro would be connected to the accumulator. Very interesting idea -- kind of the same concept as a header tank in a fuel system. Has this been tried before? Mike F.
