You might consider making what would be the tray bottom in my design and modify it to include an inverse box section to hold/guide the batteries tray as in an elevator shaft. This way you attach at the top of 6V7-1 and reach over to bottom flange of 6F1-6 to use common rivet lines for the tray. Then the "boxed" .040 battery support and belly cover could slide up into place and be secured by 4 or 6 lock nuts and AN525 screws. Pictures of my dual battery tray are in the electrical section and large assembly/fuselage to center section segments. You have a great idea for externalized access going there. Wish I'd thought of it. Very interested in what you've done with the disributor, pickups and control modules. When you have the time to comment further on it please do.

Thanks, Martin Bima STOL-Vair plans built > Winnipeg, Canada Martin, I measure 35 mm on one end and ~40 mm on the other. Try checking the distance from elevator leading edge to the trailing edge. To bring the skin tight to the ribs I used a strap & turnbuckle fixture to coax the skin into place. To prevent twist the elevator should be strapped to the flat workbench at this point, and at the same time. My elevator came out good, no twist, no gaps. The geometry of the ribs could result in some difference in the dimension you wonder about. The trailing edge needed to be trimmed a bit to bring the top and bottom skins together. I went for a straight trailing edge as I trimmed it. The elevator will be different on each side when the trim tab is installed. Jerry Erickson CH 701SP

    Subject: Rudder hinge plates 701
    --> Zenith-List message posted by: "Johann" <johann@gi.is> Hello list members. I need your advise on the rudder hinge plates for the Z-701. When aligning the rudder hinge plates on the rear fuselage, I noticed a little twist in the fuselage from level above landing gear to the aft part of the fuselage. I assume this happened when I riveted the rear fuselage together. The longerons should have been riveted together all at the same time instead of one at a time, and all in a jig, to avoid the twist.????? Has anyone had this problem and if so, how did you solve it? How did you install the hinge plates so that the rudder hinge was vertically correct? Ref: page 7-F-4. Another question: On page 7-F-14, Edition 4 06/2001. Did you install the 7-F-14-1 = cowl support, 7-F-14-7 = Lower Dzus plates, and 7-F-14-2 = Lower Cowl Support. Reason I ask is that in the new photo assembly guide, those parts are not there. I wish you all a Happy New Year. Best regards, Johann G. Iceland.

    Subject: Re: Aeroflash strobes
    --> Zenith-List message posted by: "Greg Ferris" <ferret@wmtel.net> Dave, My experience on the phone with Aeroflash wasn't much better. She actually said: "the only problem we have is when these homebuilders decide they have to buy everything years in advance of using the strobes and they hit them with full voltage". I shared with her that I am a homebuilder and that there was no documentation included with my strobes that warned me of this issue. Also I educated her that homebuilders typically do not build an entire aircarft in less than a year, and it is not obvious to a "normal" person that you have to worry about how long a power supply sits around. It was one of those moments that one wants to jump through the phone line and choke the person on the other end. I really don't want to fix the power supply myself, but I'm pretty much doing it out of spite because I can't bring myself to pay them more money. If I would have sent it in and gotten it back COD, I would have blown a gasket.

    Subject: R912 oil tank brackets on 701
    --> Zenith-List message posted by: ZSMITH3rd@aol.com Have most builders had to cut off part of the bottom end of the LEFT & RIGHT oil tank brackets to make things fit when mounting the 912 oil tank? Secondly, is the hose clamp across the oil tank filler neck the only thing holding the entire tank assembly? The "photo guides" I have don't show any sort of strap or other retention device. Any anti-rattle suggestions? Looks a little flimsy, at best. Finally, just in case the internet gets clogged up tomorrow and hinders serious message traffic, a very prosperous and Happy New Year to all. Zed Smith 701/R912/the proverbial 90% do not archive

I would think keeping the flash units protected from the elements would have been good enough. I would have loved to have an excuse to power them up once in a while when I was building and making airplane noises. How would we have known? She gave me the impression that everything would be great if it wasn't for the #$%! homebuilders. Lately I have had friends flying with me in my 701. It is great to see they are just as excited about how well it flies as I am. Chris has designed a GREAT plane that is perfect for the type of flying I want to do right now. I flew 2.2 hours today and burned 6.5 gal. Now that makes me smile! The day included lots of departure stalls (0 mph indicated, 500 fpm climb) steep turns, touch and go's, and a 20 MI trip out and back to visit friends. It seems I can land just as short with 15deg flaps as I can with 30deg. I guess the 30 deg. setting would be used over very tall obstacles? It is also easy to lose airspeed just before flair with the 30 deg. setting. I plan to use the full flap setting sparingly. BTW wouldn't it be great to have a glove box with the flush door on the outside of the plane as a place to keep the fuel checker and fuel qty sticks? Maybe attached to the aft bulkhead of the baggage compartment? I wish I thought of it before I painted mine. Incidentally, Van's sells a very good glove box. :-) Dave N701XL 912 ULS Do not archive

    Subject: Re: Aeroflash strobes
    --> Zenith-List message posted by: "Greg Ferris" <ferret@wmtel.net> I have had a blast with my 601HD. My son and I are flying up to Minnesota tomorrow to return extra paint from when I painted it this Fall. (I used Aerothane, and I'm happy with the results)We're going over to Cabella's from there on the way back. Hopefully the weather pans-out. I suppose I'll pull the power supply out of the wing on New Years and see what lies inside. If I would have dreamed that 70 hours later I'd be removing a power supply I might have made it a bit easier to remove and install them; live and learn I guess. The fuel economy of the plane and canopy are the things I have enjoyed the most. To fill-up after a 3 hour trip and take less than 12 gallons is very nice. I attached a pic of the bird for you to check out. I'm going to make some wheel fairings this summer. Happy Flying!

Their attitude toward the homebuilder community could adversely impact their business in the end - not to mention poor engineering and a growing reputation for very poor customer service... I did power up my units (with 12 volts AS SPECIFIED IN AEROFLASH DOCUMENTATION) and they do function but I'm a long way from installing the wing on the fuselage. I hope to not experience a failure but am concerned with the plethora of reports on this list. It would be wise to log all correspondence with AeroFlash (when/who/what) when discussing a premature failure of these devices in the event that outside consumer support for remedy for a claim might be easier to substantiate. Certainly the discussion on the list would tend to support those of you who have already experienced failures and might seek remedy...

    Subject: Re: Rudder hinge plates 701
    --> Zenith-List message posted by: Mike Sinclair <mike.sinclair@att.net> Johann Sorry I can't help on the twist problem. I did look at the plans and see that I did actually install both the 7-f-14-1 and -2 parts. With the way my cowl attaches I feel fairly sure that they will help with the rigidity of the installation. About the 7-f-14-7 lower dzus plates, I see that I did not add those to my plane. I also looked through the very small pile of parts left to install and did not find these parts. Evidently these parts were not something Zenith felt the "need" to include in the kit, and this is the first time that I have noticed that they were missing. I also did a little looking at the way my cowl attaches and noticed that this is also the least substantial attach point of my whole cowl. Fortunately I built in a little redundancy on my cowl attachment so this will not adversely affect the strength of my cowl. Mike Sinclair Hoping to have the wiring fairly well wrapped up over the Christmas break. Should be hanging the wings and doing final rigging in the next month or so. Painting early March and hopefully spend the spring flying off the restricted time. Am going to add suitable access panels so that I can get to my Aeroflash unit when it craps out because "I was so stupid as to buy it and install it in the wings a couple of years before I actually flew"!
