I was really wondering what the h... kind of mistake had I made??!! :-) Answers that confirm that others have had similar problems really help a builder not feel so alone and isolated. And Paul, thanks for the dimension check you made. BTW, I did have the longeron sandwiched between the bottom skin and the HT Frame. I apparently just casually measured the end of the bottom skin at 92 mm and then made the holes at 72mm center to center. Since it confirmed my actual measurement of edge distance, I was satisfied :-) It appears after actual measurement that the holes are really closer to your measurements of 77mm (I got 76). However, after doing the math, the HT Frame has a width of 104mm or so leaving a non-trig difference of 104-76=28mm or 14mm in from the inside edge of the longeron. With the inside width of the longeron at 21, this leaves 7mm. However, I still wind up with only 6mm when actually measuring the edge distance on the longeron. I love math when it agrees with the facts but it's a real pain when it doesn't! I'll wait to hear what Nick has to say. He usually responds fairly quickly and I'm sure those guys can't wait for another day of answering questions! I may request that Nick send me some longerons that are 22x26 so that I can get a better edge distance in this area. After all, these tail loads are not insignificant. But I also have a gut feel that due to spacing and thickness of material, the 22x22 should be sufficient (famous last words). Again, thanks for your responses.

If not, just tell me to go back to my shop and drill more holes. :) You can actually buy individual parts from Zenith - not even whole kits, but individual parts. I got my horizontal stabilizer spars this way. In the builders section of the Zenith website there's an "Online Kit Parts Database." You can type in the part you're looking for and it will show you how much that part costs. One caveat though - some of the prices are out of date, and there are a lot of parts missing for the XL. I think they've pretty much quit maintaining the database, but it's still very useful. In case I can't find what I'm looking for, I just call 'em up and price the part. Here's the link for Aircraft Spruce nylon. For some reason they put it in with the metals. I guess by their thinking it's a "raw material." http://www.aircraftspruce.com/menus/me/nylon.html Enjoy!

I recently discovered that my fuel pumps are less efficient in flight. Fuel pressure (which is measured at the gascolator) gets down to ONE psi. I have one pump at each wing tank (Fred, I'm not sucking fuel :-) I also have a third pump at the firewall. Performance is the same with both the left and right pumps. I feel the pressure is a tad higher when using the firewall pump. I did a test on the ground. Fuel flow is exactly the same from the 3 pumps and is same as new pumps (25 gal/hr). Fuel pressure on the ground is normal (5 psi per pump approx). Anybody would know why I don't get the usual 3-5 psi in flight? (now it is more like 1 to 3) Yesterday, as a workaround, I used the firewall pump in conjunction with the wing pumps (firewall pump is in series) and I got 4-6 psi. Michel PS: the pumps I use are the Facet 40108 pumps. The wing pumps have approx 200 hours of use each. Firewall pump is much less solicitated. ---------------------------- Michel Therrien CH601-HD, C-GZGQ http://mthobby.pcperfect.com/ch601 http://www.zenithair.com/bldrlist/profiles/mthobby http://pages.infinit.net/mthobby __________________________________________________ ________________________________ Message 4 _____________________________________ Time: 06:01:24 AM PST US From: Brian kissinger Subject: Zenith-List: Flying techniques and Stick & Rudder Greetings everyone: I not a very good builder and I am not much better as a pilot. However I do have a CFI rating, thousands of flying hours, flown several different taildraggers, currently own/fly a Luscombe, taught some people how to fly and given several tailwheel endorsements. I haven't killed myself, wrecked, or groundlooped any airplanes....yet. I wholeheartedly agree with the endorsement of Stick & Rudder. It's an essential book for every pilot. The first time I read part 1 "Wings" and Chapter 1 "How a Wing is Flown" it cleared up so much confusion in my previous 16 years of flying (including Air Force training). Get it, read it, re-read it. As far as crosswind landings go...I've seen 2 main schools of thought. What I like is what I typically teach in a taildragger....wing low into the wind to stop cross track....opposite rudder as needed to keep the nose pointed straight down the runway. Other pilots like to maintain a crab into the wind and then take it out when they are close to the ground. There can be a heated debate on both sides of this topic. As far as the 701 goes, I flew with Roger at the factory again a few weeks ago and he said the plane is recommended not to be slipped (by Chris Heintz). He demonstrated to me in a power off/nose high configuration that the airplane will come down quickly and then added power as we got closer to the ground for a soft landing. That was Roger's technique. I know many on this list have been flying their planes for hundreds of hours and will probably have their own techniques that work. Thanks everyone for sharing information on this wonderful builder's list...I am glad Jon survived his crash and I am glad our airplanes are designed to take a beating.

ZAC set up an impossible situation by clearly calling for the skin to align with the tangent point of the longeron bend at the tail end of the fuselage and taper to the sharp edge of the extruded front longeron. This makes it impossible to get a 10 mm edge distance on both the longeron and the skin. Since the skin was already drilled with a 10 mm edge distance, the longeron edge distance must suffer. I thought about placing a second row of rivets, offset from the first row, with a 10 mm edge distance on the longeron. Decided that was just overkill.

Your comprehensive coverage of this topic leads me to ask you for further information and opinion. First is the issue of performing a forward slip landing with flaps (or in the case of the 701 with slats). I think I have heard several instructors suggest that either flaps or a slip is appropriate for losing extra altitude on final approach but not both. I don't know why both would be inappropriate, but I have never done the slip with flaps because of that comment The kind of slip I am talking about in this case is not the light one to compensate for a crosswind but the deep one used to dump altitude. The other issue is one that has bothered me ever since contemplating flying again after some 15 years on the ground. It seems popular today for pilots to land light planes with power all the way to touchdown. I know this is common practice with multiengine planes, but in the old days I was taught to make the final approach with power off (unless there was a good reason to do otherwise like trying to stay ahead of heavy traffic at high use airports). I think the power off approach works just fine in most cases and also gives the pilot plenty of practice for dead stick landings in case of engine failure. I don't know of any advantage of using power on all approaches other than it makes them a little easier to perform. Sadly, there seem to be too many owners of light aircraft who come to a bad end when they fail to make a good approach after an engine failure and hit the only tree around or fail to clear the final hurdle. In Roger's case, I can't help but wonder what will happen if his "Behind the curve" dumping of altitude is punctuated by a failure of the engine to slow the descent as you described. I have heard of doing that sort of approach with power on, but never with power off. The power on version is somewhat like a helicopter landing and allows for crazy pilots to make incredibly short ground rolls, but is not for the uninitiated or weak of heart. I would love to hear you comments on the above issues. Best regards, Paul XL fuselage > >I not a very good builder and I am not much better as a >pilot.

You could call Shirley at ZAC and find out for sure. Another option is to buy your 4130 tubing from a source like Speedy Metals, cut them to length, fishmouth them, and take them to a welder to get them welded... Of course you'll end up with the price of the tubing and the price the welder charges, but I'd say you'll end up with about 25% of the ZAC price for the same parts...

I'm not a welder (at least not a good one) so I need to purchase some parts already made. The rudder pedals come with the fuselage kit and not the controls kit. How much does ZAC charge for the rudder pedals? Also, where do I get the nylon to make the bearing? I checked aircraft spruce and didn't see any. I guess if I buy the pedals from ZAC it comes with the nylon but there are other areas that call for nylon. Do most scratch builders purchase controls or fabricate them? On the homebuilt help DVD about scratch building they mention a hardware kit but of course don't mention a price. I don't see it anywhere on ZAC's website. Sorry for rambling on.

You can either be taught what to DO in a certain situation, or you can be taught WHAT NOT TO DO. Go back to my original post. I've experienced CFIs that freaked out and told me NOT to use Langweishe's (Sp?) techniques. I was seeking help in improving my landings in a C-172 that turned out to be out of rig, and he couldn't do any better than I could. On the other hand, I took a couple of hours of dual from a CFI who got a big smile on his face when I told him I was building a plane that didn't have flaps and wanted to learn every trick in the book for no-flaps landings. We had a blast, but my son, who was in the back seat, was a little green around the gills. Now, what side of the fence to you think I'm on?

I also was taught to land light planes power off, and only carried power when necessary, generally to lengthen an approach. I use the slip and full flaps to drop out of the sky when needed, or just for the fun of it. It's a very good exercise for coordination, just keep one eye on the airspeed. I've found the technique very impressive when a CFI on a biannual cuts power at 1200' mid field and wants a simulated engine out landing. You can stay very close to the field with a rapid decent and if it looks like you may come up short -- start easing up on the slip and/or some flaps. This was a regular maneuver for me in a C177 Cardinal I owned for more than 10 years. I'm wondering if there is a reason NOT to slip with full flaps in a 701?

Your comprehensive coverage of this topic leads me to ask you for further information and opinion. First is the issue of performing a forward slip landing with flaps (or in the case of the 701 with slats). I think I have heard several instructors suggest that either flaps or a slip is appropriate for losing extra altitude on final approach but not both. I don't know why both would be inappropriate, but I have never done the slip with flaps because of that comment The kind of slip I am talking about in this case is not the light one to compensate for a crosswind but the deep one used to dump altitude. The other issue is one that has bothered me ever since contemplating flying again after some 15 years on the ground. It seems popular today for pilots to land light planes with power all the way to touchdown. I know this is common practice with multiengine planes, but in the old days I was taught to make the final approach with power off (unless there was a good reason to do otherwise like trying to stay ahead of heavy traffic at high use airports). I think the power off approach works just fine in most cases and also gives the pilot plenty of practice for dead stick landings in case of engine failure. I don't know of any advantage of using power on all approaches other than it makes them a little easier to perform. Sadly, there seem to be too many owners of light aircraft who come to a bad end when they fail to make a good approach after an engine failure and hit the only tree around or fail to clear the final hurdle. In Roger's case, I can't help but wonder what will happen if his "Behind the curve" dumping of altitude is punctuated by a failure of the engine to slow the descent as you described. I have heard of doing that sort of approach with power on, but never with power off. The power on version is somewhat like a helicopter landing and allows for crazy pilots to make incredibly short ground rolls, but is not for the uninitiated or weak of heart. I would love to hear you comments on the above issues. Best regards, Paul XL fuselage I not a very good builder and I am not much better as a pilot.

Does that hole go straight up through the cap? What about water entering the tank? I have had the left tank burn off sooner than the right. I have fuel shut off valves at the door headers so I can shut off the side that has less fuel than the other to balance them out. Lately they have been going down pretty evenly. Bob Spudis N701ZX / 55hrs Bob, The reason I asked is that on previous list postings about fuel feed problems no mention was made of the cap configuration, per the ZAC print. What changes from the static gravity fuel flow tests, to the in flight system operation is the air pressure in side the tank. Change in the fuel level, head, and change in the tank pressure will effect the ability of the fuel to gravity feed. As to the location of the hole, I plan to drill through the middle hole already located in the spring tensioned that is riveted in place in the cap. But only thru the inside section. The fuel caps on the 701 demo at SAC, have been modified to include a ram air tube with an L brazed or welded to it and to the cap. That is what I am planning on. Some time ago a list 701 builder mentioned that in addition to using a ram air tube, like Tony Binges suggests, he also soldered shut the four edge vents inside the cap. That makes since to me because those vents live in the upper wing surface low pressure area, during flight. So, it seems like the pressure would reduce in the tank, due to out flow suction through the four edge vents in the cap. Make since? So that would result in the ram air tube feeding the tank, with no leakage at the edge vents. The cap gasket seal might also need work to assure a good seal. Prevent fuel siphoning, Prevent air siphoning too. Perhaps a viton type seal rather than pressed cardboard?? At any rate, if the gravity flow is OK during 14.7 static tests, ,,,, and has less flow during flight, something has changed. I'm thinking that the inside tank air pressure becomes less than atmospheric, resulting in less fuel flow. Also as fuel is used from the tank, there is less fuel head to aid in gravity flow. As to bubbles living in the fuel lines, and blocking fuel flow, it seems so sensitive as to be in need of a serious fix. Would it be more prone to occur during hot weather,, or when using auto fuel, or just after draining the gascolator?? Just wondering out loud here. Good luck with solving the problem, and please do keep us posted.

Over the past 2 days I've been scratch building my wing tanks... I plan on doing a top installation of the fuel senders. Not really knowing the exact location of where to cut the hole for the sender in the top of my tank I did the following: 1. I put the tank on my level table and using a wooden block under one end of the tank, simulating the dihedral of the wing. 2. Next I put a level flat on the table beside the tank simulated the fuel level. I wanted my sender positioned in such a way that when the float hit the bottom of the tank, I would still have approx. 3 gallons of fuel in the tank. (Inboard bottom corner of the tank.) 3. Sliding the level back and forth along the table you can manipulate the point where the fuel level and tank bottom meet. After doing some calculations I came up with a placement of my sender where approx. 3 gallons would be left in the tank when the float hit the bottom of the tank. I guess my real question here is: Do you guys see anything wrong with the way I'm doing this? Am I overlooking an important item in all of this? The measurement I came up with is that the sender would be 420mm from the inboard tank end, measure towards outboard.

It's being able to see the float jiggle to a low fuel setting that offers an idea of how far it is to empty. It would be my preference to know that to within the last gallon. Where it is when it's full or above half is of little consequence compared to the gage that will read nearest empty. Otherwise you'd be guessing when it hit bottom or if it hit bottom with 3 gallons in play due to the movement of the plane. My gages read to less than half a gallon and it's easy to tell when they've stopped moving.

Fred- Do me, yourself and your passengers a favor------- get this problem fixed before you fly. Your "band-aid" cure is only giving you false security. If you want to fly under this (air bubble in fuel line) circumstances fine, but it is not fair to your passengers. You may be betting your life on the statement: "I'm sure there it is not enough air to cause the engine to quit." Fritz fred sanford wrote: --> Zenith-List message posted by: fred sanford The bubble either stays where it is, moves down the line and stays there, or some of it comes out of the output. I'm sure it is not enough air to cause the engine to quit, but it is disconcerting to see one tank empty, and one full! I am making a fuel cap with a 6 foot hose, so I can blow any bubbles into the opposite tank as part of the preflight before any long flights. Should fix the problem.

The respirator will keep you safe as well as eliminate your having to smell the stuff in process. Nowdays, I get deathly ill if I don't have the respirator on with the resin container lid off. Do wear latex gloves. Acetone will cut the stuff better than anything. You need more guidance on doing fiberglass, I can summarize it for you, or you can read up and get there off the Internet.

If you set them up to read accurately when the tanks are full, you'll still have a few gallons left when they read empty and if you position them to read accurately at the bottom end of the scale, you'll burn off a few gallons before they move off the full mark. I would say that the guage should read empty when the tank is empty. That way, you won't be tempted to try to stretch your flight a little further thinking that you still have that three gallons left in the tank. When the guage reads empty, it's time to land, now, because you really don't know how much fuel is left after the gauges bottom out. It's much more critical to know when the tanks are going empty. I don't care about the first few gallons I burn, it's the last few gallons I worry about.

Fred-- I didn't miss it, it just didn't re-print for some reason. That is my concern. the problem isn't being fixed. I don't want to beat this to death, but I am concerned. I can only tell you what I'd do: 1) I'd put on new vent caps built like one other lister discribed and built like Tony Bingelis shows in his book. 2) I would install a fuel control valve like Chris H. calls for in the 601XL--- that is a 3 way position valve: left/ off/ right. THE PILOT SHOULD BE CONTROL THE FUEL FLOW. Allowing both tanks to gravity feed at the same time adds to your problem. Honestly, I would not fly in your airplane with you under these known conditions.

I've been told to avoid slips in a 4-place Cessna with full flaps when the rear seats are occupied but I've never had any problems. I own an Aeronca Champ and fly it into my 1200 foot strip over obstacles so slips are a part of every landing. My suggestion to anyone new to slips is to practice at altitude, especially in an aircraft whose flight characteristics are unknown to you. Slips should be performed at normal approach speeds (approx. 1.3 times stall speed.) Slips attempted when an aircraft is at the ragged edge of a stall may lead to a spin entry. I would suspect that Zenith aircraft, in particular the slab-sided 701 & 801 would slip very nicely. Slips are a great way to lose altitude in a hurry and I like the fact that the moment you remove the slip you're back flying normally. You do need to warn your passengers, however.

For the wings, the Assembly Guide recommends McMaster Carr 12' 1-piece ratchet straps (#8842T17), and does not recommend the number needed. Is there any reason I can't use the same straps for both the stabilizer and wings? How many will I need for the wings?

I only got the "old" assembly manual. It's in there, but you have to read carefully, closely, and patiently......I nearly wore out a pair of shoes walking around the tail area looking.....you only get to drill the holes once; make SURE before you drill. A good measuring tape and an electronic "smart" level will do the trick. For left-right, just attempt to get the fuselage level....tire pressure will do this, measured at the rear of the cabin/front of the rear fuselage. For fore & aft, as I recall, the instructions call for the top side of the horizontal stabilizer to be parallel with the top of the fuselage, and XXX mm above (don't remember exactly, see manual) the fuselage top. The "smart" level will read out in tenths of a degree..... simply read the level and make the horiz stab agree with the fuselage. Same for the port-starboard setting. Biggest problem is making sure the rudder and elevator move through the proper arcs without binding before you nail the horiz stab. This is really a two-person task, although with scrapes and cuts and a great deal of loud expletives you can mount these parts alone.
