    Subject: Re: Nav antenna location?/200 mph
    Tony Thank you for the reply. That sounds like a reasonable way to proceed, given the info from ZAC. I suspect they increased the gross to 1320 in response to the release of sport aircraft limits (no doubt as a result of static load tests). But, I'd like to know why they changed the Vne. I am confident that the XL at 160 mph is well within it's safety envelope, but excessive wing load is a serious matter, see "Faulty ADM Kills" in http://overtheairwaves.com/vol3-20final.html for an extreme example of the consequences.

    I cut down two FM whip antennas to about 26" (a little shorter than a 1/4 wavelength at the middle of the VOR band) and mounted them at about 120 in a 3/4 inch PVC pipe cap. I used a "bazooka" balun. The reception is pretty good. On Dec 26, 2006, at 4:21 PM, Eddie G. wrote: > <silentlight@verizon.net> > > Bryan, > > Did you go with a 45* rabbit ear or 90*? What length?

    Dave, Thanks, I have the orig. continental repair/parts manual. Will study it this week. If the job is as easy as you say, I may change the engine before DAR time. If it appears that it will take me to long to get done (I am slow), I will get the airworthiness inspection done, fly off the airplane and then change the engine. We are at 2,600' +/-. The A-65 appears to be good for this airplane. I cannot hold the airplane with full throttle - unless it is tied down. Wants to "skip" on the pavement with the brakes held tight. That is at 2200 rpm. Gonna re-check/adjust the brakes tomorrow morning and see if anything changes. -- Semper Fi, Steven R.

    Subject: VG's
    As for placement I tried 12%, 10%, and 8%. I settled on 8 %(LE of VG at 147mm forward of rivet line on top of spar on my plane). 12% was too far back. At 10% on an extremely aggressive takeoff rotation the vgs would occasionally "uncover" and result in an extended takeoff roll. I haven't been able to force this situation at 8%. I would stress that it is important to do your own flight testing before making this commitment as each of these planes is different and your results may vary considerably from mine. Good Luck Joe

    Subject: Re: Are these the J-Nuts?
    Hi Terry, I've had the u-nuts and j-nuts in service for over 2 years and can find no signs of galvanic action on them or the cad plated steel screws. Nothing was done to address the problem, but again, as the forward top skin has been off a 3 or 4 times this past 2 years, there is no evidence of corrosion. I don't believe there is any potential, unless the aircraft was constantly exposed to rain and snow or the plane had to set in a hangar within a mile of ocean salt air. I see they've been phosphate treated and that's probably why they are without corrosive activity.

    Subject: Re: Landing Light Lens Trimming
    Brad- 1. I put duct tape on both sides (Front+back) of the cut line and cut with a fine blade and high speed on my bandsaw. Leave a little extra stock for the inevitable little chips and finish up with a belt or disc sander. 2. I went down to the local hardware store and bought a batch of springs of differing lengths and compression strengths to compensate for the final lens mount angle. It's a lot easier to install a short spring where necessary than to try to install longer, "One size fits all" springs. Hope this helps.

    Subject: canopy fitting
    hi list i am trying to finish my canopy so i can send the fuse out for paint. i have avioded this step for as long as i can, but must get over this final hurdle. to me, this is the most difficult and illogical part to complete. nothing seems to progress in any rational pattern. i now believe that in order to have the thing fit right, i will have to do major triming on one side of the plexiglass. the manual suggests that some triming will be needed to fit the open/close lever. i am going to put it on and trim one side so it fits evenly over the left and right rail. i will do this unless someone out there has a trick or believes i have made some major mistake in my construction of the machine. i would gladly have paid extra to have a completed canopy section sent. this part is far from an exact science. perhaps i am just getting frustrated as i thought i was near completion. those tubes drive me crazy. any comments or suggestions would be welcomed john butterfield 601XL corvair torrance, ca __________________________________________________

    Subject: CH601XL center spar webs - drilling six 1/4" holes
    From: "ashontz" <ashontz@nbme.org>
    Newbie here. I'm making my center spar webs at the moment and I made a mistake by flaring the holes in the web before laying out and drilling the six 1/4" bolt holes. I'm thinking of correcting this by placing a piece of 3/4" MDF board in between the two webs (with a hole cut out of the board for clearance of the flared holes), clamping the whole thing together tightly, with the two flanges set against each other as specified in the plans, just with a 3/4" board offset instead of being flat against each other, and then drilling the 1/4" holes. Does this sound like a reasonbly safe method for getting the holes aligned properly? Seems to me, drilled either way, that the piece would still be floppy enough before being mounted in the fuselage to allow enough play to get all 6 bolts in place properly.

    Subject: Re: RE : Questions About Bending Brake
    From: "ashontz" <ashontz@nbme.org>
    I have an 8'+ bending brake I made out of 1/4" thick by 3 1/2" steel angle made with the same bending pivot idea as Zenith's brake. Despite what they say, you can extended that brake to a full 8', you just need to beef it up externally. I can bend .032 no problem. .040 I need a couple extra clamps in the middle, but evereything below .032 is a piece of cake and straight. My brake desing also allows for full depth bending (ie. rudder skin etc...) because the clamp attach points are at the ends, no in the middle. Again, beefing it up externally like a real brake is the key. The brake I have only cost about $300 including the materials for the dolly and doesn't require any special machining operations (no milling, no lathe work). You can make it with a metal cutting band saw, drill press, hand grinder, and assorted basic hand tools. No welding required at the joints either. The only welds I have on it are where the bow tensions are mounted to the bows, and I'm sure something else could be done there too or taken to a welder for $10. Perfect for sheet up to .032 (did my web spars on it, al within 1mm) and good for .040 shallow depth sheet (stiffener L's etc...) with a few extra clamps. No need to file a 1/8 radius either. It was already on the steel by default. Just cleaned up the edge. Truly a handy thing to have around the shop a problem free 8' bending brake for around $300.

    Another canopy question- I'm ready to start on the canopy, but am limited presently by a low 7'6" ceiling. I'm thinking of putting the fuse flat on the floor with the gear removed, and wondering if that will allow enough head room. Can the canopy be properly fitted without having to open it fully?

    Hi all, I am wondering the source scratch builders are getting their 3/4 x 3/4 x .093 Aluminum angle. Spruce has 3/4x3/4x1/8. I screwed up my elevator horn doubler 6t3-6 by trimming off to much and was thinking that some raw materials around the shop would be a good thing. All this talk from the scratch builders has me thinking, that I should be able to recover from some mistakes that are simple. maybe a couple of small sheets or .040 and .032. To form some common parts. Is there such a thing as a hybrid builder out there? Thanks Ernie. Do not archive. On 12/27/06, Bill Naumuk <naumuk@alltel.net> wrote: > > Wade- > Deja vu all over again!

If it's 1/4" thick, and the edge is round, it's therefore a 1/8" radius. I just cleaned any rust and high spots off of it before using it. No need to file a 1/8" radius, it was already there. Even Zenith's brake per the plans made a mention of a 1/8" radius already on the steel angle and to just clean it up.

    Any "honest" builder will own up to messing up some part or the other. Yes, sometimes, it is best to go to ZAC for another part; but most of the time it is easier (and definitely quicker) to fabricate another part yourself. I have probably made a dozen replacement parts (confession is good for the soul, I am told). Get over your "boo-boo", set your mind to it, recover and move on.

    Subject: Re: Screw-up
    Hi Ernie, What I have done is to replace man kit parts I screwed up by building them from scratch. This is much easier than actual scratch building because you have the kit part to compare to your new piece. Many of the kit parts are easy to replace. The ones that are a bigger challenge are the very large parts with long bends and things like the wing spars that also have solid rivets to deal with. You can order replacement parts from ZAC. You can also order replacement materials from them or any other source that has the right stuff. In the case of 6061-T6 sheet metal and extrusions there are many sources. This material is very common in the market place for use in all sorts of stuff - not just aircraft or mil. spec. use. At some stage, ZAC will include some spare materials in your kit box too. The only advice I can offer is to do what ever you are comfortable with. If you don't like your results and feel uncomfortable then order replacement parts. The nicest part of all metal construction is you can undo just about anything and keep working on it until you are satisfied. It is you, the builder, who must take responsibility for all the parts and the final construction.

    Subject: Length of Aileron Rod?
    Chris, No mistake, the rod is too long, on purpose I guess. I screwed the rod into the bellcrank connector, held the aileron at neutral, placed the other end of the rod along side the aileron connector and "eyeballed" the location for the cut. I cut it a little long and trimmed it later for a proper fit. Since it is a stainless steel rod, it will not be easy to cut and you will probably have to dress the end threads to get it to screw into the connector. It's really not too hard a job. Good luck!

    Ernie- We're all "Hybrid" builders. I haven't seen a completed project yet that didn't include some embellishment to the basic plans. The way I figure it, if you're making a non-structural mod ( Fairings, light installation, etc.) go for it. On the other hand, if you're considering making a flying surface larger or smaller or modifying the gear, list advice isn't for you- you should talk to Zenith. As far as I know, you only incur a weight penalty if you go to the next size larger stock. DON'T THROW THINGS- I SAID "AS FAR AS I KNOW"! The big problem with using .125 stock for the horn is, it's hard to bend, and you're not allowed to heat it with a torch.

    <I am looking for some sort of CG range data for the <slatless wing-if anybody has or knows would appreciate it We have three slatless 701's at our airfield, and some experience with adjusting CofG. Hans' (912S) weighs in at 503kg (1107lb) at 26% m.a.c., loaded for travel, with 82kg (180lb) pilot, 95litres (25gal) fuel in wing tanks, two jerrycans of fuel 28kg (62lb) on pax seat, and 20kg (44lb) baggage. Gene's (912) weighs in at 496kg (1091lb) at 25% m.a.c., loaded the same as above. Hans' and Gene's were actually weighed in that loaded condition on professional scales. Phil's (912) was weighed empty, and the loaded conditions calculated. It weighed in empty at 283kg (623lb) at 22% m.a.c. This a/c has the original 40litre (10.6gal) fuel tank forward in the cowl, and 40litre (10.6gal) in the wings. Calculating the most forward CofG, (single pilot 82kg and full forward fuel), gives CofG at 21% m.a.c. Calculating full load CofG, (full fuel (80litres), pilot 82kg, pax 82kg, no baggage), gives 502kg (1109lb) at 28% m.a.c. Due to that forward fuel tank we had to put the battery right back in the tail to get the most forward CofG to 21%, which is still quite far forward...... This a/c has a history, in that when we bought it in a crashed condition the battery was forward of the firewall, so what was the actual CofG! The crash occurred when a ferry pilot, unfamiliar with 701's, tried to take off from a short strip and then tried to abort too late when the aircraft didn't want to rotate easily........ More detail on that in a separate post - there's lessons there I think. Of the three aircraft, Phil's balances the best with a CofG at about 27% (pilot + pax + part fuel), Hans' balances well at 26%, and Gene's feels just a little bit nose heavy at 25%. This is testing the balance in glide, and the ability to flare comfortably at idle power. The next testing we will be doing is to adjust Gene's to 27% to see if it feels better there......

The original 1/8 inch plate at the bottom of the gear should be replaced with a 3/16 inch plate. This is in addition to the wheel fork doubler 6L1-3HD. Zenith will sell you a new gear leg 6L1-1 for $58 each plus shipping and handling. -- Craig

    Hi John, Do look over my website Canopy page. It is progressive and pictures the evolution of completing it without any words. I'd not paint until the canopy sides and forward arm covers are ready as well. Tape your canopy down after you've trimmed front and back to within a quarter inch from the skins with the latches locked. Trim the sides after getting position for the front and rear edges where they should be. I don't recommend the front edge flashing as it's unnecessary if you trim close. Don't get in any hurry as this will lead to mistakes. If you use painter's tape to secure the canopy and common reference points drawn on the tubes and the canopy, you' ll get consistent position from which to make the cuts around the latch lever. Ink marker works. Doing the canopy is a bit of artwork in measuring and cutting, but it can be done by completing each segment of the thing just one problem at a time. Good luck, Regards, Larry McFarland 601HDS at www.macsmachine.com john butterfield wrote: > > hi list > > i am trying to finish my canopy so i can send the fuse > out for paint. i have avioded this step for as long > as i can, but must get over this final hurdle. to me, > this is the most difficult and illogical part to > complete. nothing seems to progress in any rational > pattern. > > i now believe that in order to have the thing fit > right, i will have to do major triming on one side of > the plexiglass. the manual suggests that some triming > will be needed to fit the open/close lever. > > i am going to put it on and trim one side so it fits > evenly over the left and right rail. i will do this > unless someone out there has a trick or believes i > have made some major mistake in my construction of the > machine. i would gladly have paid extra to have a > completed canopy section sent. this part is far from > an exact science. > > perhaps i am just getting frustrated as i thought i > was near completion. those tubes drive me crazy. > > any comments or suggestions would be welcomed > john butterfield > 601XL corvair > torrance, ca > > >

    Robin, Putting the fuselage down 12 to 18 inches will help with fitting out, deciding clearances front edge to forward top skin and also for connecting cylinders several times. Just measure the length from the pivot point to 6 inches behind the B2 bow and set an angle of 80 degrees from the pivot. See link to get an idea of what is, http://www.macsmachine.com/images/canopy/full/canopyup4.gif Larry McFarland 601HDS at www.macsmachine.com do not archive Robin Bellach wrote: > > Another canopy question- > I'm ready to start on the canopy, but am limited presently by a low > 7'6" ceiling.

    Per AC43.13-1B/2A "Acceptable Methods, Techniques, and Practices AIRCRAFT INSPECTION, REPAIR & ALTERATIONS" in Table 7-8 "Turnbuckle safetying guide" for 1/8 cable using Single Wrap use .040 Stainless steel, Monel or K Monel or 0.057 min Copper, Brass. For Double wrap use 0.040 Copper,Brass (Galvanized or tinned steel, or soft iron wires are also acceptable for Copper,Brass).All material should be annealed condition.I highly recommend all builders procure a copy of the above AC, I believe you will find it invaluable. It also shows the proper way to single or double wrap safetying of turnbuckles.Tony Graziano 601XL, N493TG, 188 hrs-----------------------------------When I installed my turnbuckles, I used someone else's safety wire.
