When it was outside, last november/december, occasionally, I had to help it with a "booster pack". The batteries are 12V-18AH mounted about below the baggage compartment bulkhead and wired with 4AWG cables. The brand is "Power", made in China and purchased for approx 60$CDN each. Yuasa NP18-2 is a little bit better battery. But the Odyssey batteries seem to be made specifically for starting... this is a good consideration.

I would not use anything less than a 7ah battery as the secondary (if I use a second battery at all). 7AH is, most often, the 20 hour discharge capacity. For a less than 1 hour discharge time, the battery capacity is significanly impaired. Still, if I would go that route, I still need a more powerful battery for starting the engine.

I purposely cut them as long as possible and threaded them into the fittings as far as they would go. Then I could shorten them later if need be. (Clearly I couldn't make them longer.) They are still at the original length. As a note, I found more than once that the lengths on the plans were close but when I measured the exact distances there were differences.

N701TX ----- Original Message ----- From: "Johann G." To: "Zenith listinn" Subject: Zenith-List: Flaperon control rods on 701 -- Zenith-List message posted by: "Johann G." Hello list members. I managed to cut the gear strut fitting and bend it to the correct angle, so that I could continue fitting the wings struts. It will have to be welded again after the wing fitting is complete. However, there is another problem installing the flaperon control rods. &g t; The drawings are incorrect in the rod lengths. My 4th edition 06/2001 drawings indicate the rod length of 415 for the lower rods, and 365 for the upper. These measurements do not match up with the fitting of my flaperons. Can anyone building or flying Zenith 701 tell me what length rods they have on their setup? According to my setup, the measurement between lower rods ends is 395 mm and the upper should be 425 mm. Does this sound like your setup? Hope you can help. Best regards. Johann G.

Firstly total cost of ownership means to me that anything silid state is preferable to anything mechanical. Solid state usually means much more reliable too so a lot of the need for backup kinda goes away. You could run two Dynons and many do but its real overkill. A much better way is to have the redundancy built into an equally useful instrument that is used primarily for something else (and maybe driven from your secondary battery system). The answer Is a Digitrack auto pilot...There you are hand flying in IFR, your Dynon goes out, you hit the engage button and you plane will sit there wings level for as long as you want. As the A/p can be slaved off of pretty much any GPS (including handhelds) you simply dial in your destination and it will take you there. Now in reality you will be using the GPS to drive the A/p anyway so if the Dynon goes south it really is not a huge issue. The reality is a light IFR A/c will not have total redundancy for a lot of its instruments. Having said all this an ASI and altimeter steam guage seem to be prudent measures for backup and that is what most builders install. Incidently, even for VFR work $1500 AP would be a wonderful addition to a twitchy 601 on cross countries.

What do you do for backup - run TWO Dynon units ?? I sure would hate to be in hard IFR and have the unit quit...that's why I was thinking AI, DG, and Altimeter as steam-gauge backups. Am I approaching this all wrong? Yes, I know electric AI units are available, but they are well over $2k as well !! That leaves an electric DG ??? As always, thank you for your help and thoughts.

The primary battery can fail in a number of ways. The two primary ways are 1) An internal short in the primary battery 2) A massive short in a major part of the electrical system e.g the battery cable grounds out. In either case the massive current demand will probably cause a fire (maybe not in the case of 1) but will certainly completely overload the alternator and the battery voltage will drop close to zero...How close depends on how much current is flowing. So the failure modes (and note we havent even talked about the failure of the alternator itself) are either a reduction in primary battery voltage (hopefully one would actually notice this) or a fire. The emergency procedure for a fire are to isolate the battery via the contactor and hope the fusable link will cut off the alternator...it should. Then with a still fully charged second batt go find somewhere to land. If the alternator fails and you have plenty of fuel in both tanks I would shut off the second fuel pump and second ignition to save the battery...then fly at full speed to an airport....Before landing turn on both fuel pumps and second igntion as normal.

I missed something!... The purpose of the small battery is not to fulfill the electrical needs of the airplane, but to complement the alternator? How would the primary battery fail in such a way that the alternator does not produce the juice required to make the plane work?

Can't wait to see his numbers when he is up and flying. One thing to keep in mind is that the 701 was never designed with top end performance in mind, it is essentially a Stol aircraft which performs that function very well and can be flown quite nicely on a 582. But in a headwind it could be conceivable to travel backwards. Even with the higher HP motors installed you may still be passed by cars below you. But for flat out fun and short fields the 701 is a top performer! If you need a faster rig look at the 601 or wait for the CH152.

I agree the caulk way for all the sealing is not the best design. Several of us 801 guys have used the channel molding that AS&S sells. Ya probably can get some locally too. We also made some cowl strips to fasten at the windshield/top skin joint. I made mine out or spare .025 stuff. It does take time to fit them but is a much better seal and looks better too. Start with posterborard and make some patterns. Be careful when ya trim your windshield too, take a little at a time. If I remember correctly most of us had to remove about 1.25 inches off the bottom edge and cutting around to fit the cabin frame is a real treat to.

See the hardware section,page 75 and on. Each AN size designation corresponds to one particular thread. All AN3s have a 10-32 thread, all AN4s have a 1/4-28 thread, and so on. All AN fasteners use this system.

What do you do for backup - run TWO Dynon units ?? I sure would hate to be in hard IFR and have the unit quit...that's why I was thinking AI, DG, and Altimeter as steam-gauge backups. Am I approaching this all wrong? Yes, I know electric AI units are available, but they are well over $2k as well !! That leaves an electric DG ??? As always, thank you for your help and thoughts.

Just that I have lost, in 29 years of flying, several good friends because they were "expert" pilots and "got to get there" minded. If weather is bad to fly and there is no (comercial) flights available is cheaper to call "Hertz" to drive home than the funeral... (they are always in good weather).

I to thought about it then I looked at a 210 that has raised heads. Looked okay. The problem with filling thousands of heads may not be the slight weakening of each individual sanded rivet which you could never compute. The problem is that no matter what you fill them with, because of stress, weather, heat and cold, and general flex some of the fills will pop out. Then you have an airplane with measles. If speed is your goal for use of your time spend it wet sanding and high speed buffing would pay a greater dividends.

Is that OK or does the skin need to go UNDER the fiberglass tip? I hate to have a skin edge facing forward. Thoughts?? The ZAC plans call for the tip skin lapping over the fiberglass tip. I went ahead and did it that way on the right wing and figure I will on the left as well when I get there. Looks a little odd, but I figure that will go away after painting. Although the seam faces forward, it is not very thick and lies flat. Aerodynamically it might be better than a thicker seam downwind, although at 85mph probably makes no difference. Structurally, I like the rivet heads against metal, and put little washers on the inside to protect the fiberglass.

My thinking now is that at a minimum I would have to redesign the nose gear to trail more, to make it self center and castor more freely, and add some sort of resisance (spring or bungee to take up slack and maybe to add centering tendency to the rudder and rudder peddles. I guess I'll just listen to those with ideas about decreasing the friction in the nosewheel set up. Jim Greenough
