My up elevator cable has almost a straight shot to the elevator bellcrank. There is a change to 6B22 (Oct 03?) which places the up fairlead on 6B5-2 over the support. There is little influence on the fairlead at B5. The optional battery access door provides for good inspection of the tail cone area. 2. My spouse asked why the sticks had a left leaning tendency. The lower elevator cable is on the centerline of 6B16-2. The upper is displaced to the right of the centerline on 6B5-2 - this creates a built in bias to lean the stick to the left (left wing down)- unless corrected. 3. Reference the photos of the broken firewall engine mounts of the British 601 which was attributed to rough landings on unimproved fields. In my opinion, from what appears to be obvious fretting corrosion in the pictures, the primiary failure cause was probably a fatigue failure accelerated by loss or lack of torque on the attach nuts.

Before I installed mine I went out and bought new ones because they were new but 3 years old. I installed the 1280 HD but bought a cold weather one. As I remember from my pacer days they wear out or is it age out in 4-5 years. They color code the bungees so looking at it you can tell the age. Look in http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/99c827db9baac81b86256b4500596c4e/$FILE/Chapter%2009-10.pdf table 9.1 for the age of your bungee. The page loads up really slowly. You fly an 801 you should be familiar with going slow! I have 140 hrs on mine in 6 months and it is still up tight. I noticed that I have hit the nose wheel hard enough to use about 1/2 of the allowable movement. My nose gear does not bounce. It just soaks up the impact and returns to full up position. You do not want to bend things by using all of the allowable movement plus some! Last week I used some standard L to make VGs on the horizontal stabilizer. I can now get the nose up sooner so the nose gear has less weight on it for more of the take off run. I also have more elevator authority on landing. Unfortunately the nose still thumps on landing slow. It still will not stall power off. How are your going to replace your bungee without removing the engine?

I'll do the same when I get to it. Did you ever get any response from Zenith on your internal step mod? I think this is a great improvement on the original, and I can't really see why it wasn't designed that way in the first place. I don't see any obvious structural issues, but I was wondering if the designer did.

Tom I suspect you will need the heavier bungee. I have the 701 and the nose strut is stiff to the stops during normal use, but moves full travel quite often when back country landing and taxiing.

When we took the engine mount frame to be welded, we discovered that there were several more cracks in it, so we have decided to fit a brand new one which just arrived this week from the Czech Republic. The new one has several strengthening gusset plates which were not there on the original. We have agreed a repair scheme which basically consists of a number of additional strengthening plates riveted like a sandwich at all the mount points. We will also be moving the main mount holes slightly to line up with the holes in the mounting frame. We have come to the conclusion that the failures were probably caused by the engine frame being assembled under considerable tension, (you heave on that Bill while I get the nut on!) which pre stressed the small end plates of the mount brackets. With the vibration of the engine, one of these fatigue cracked which meant the other 3 took all the load, so another cracked etc etc. In the end there were none left and the engine was just hanging onto the galvanised firewall. How long it has been like this is anybody's guess but it certainly could have been tens if not hundreds of hours. We sent the broken brackets to the PFA here who had a meeting on the subject and concluded that it was caused by something in the way our aircraft was built (not by us I would add). Zenith took no interest in the problem whatsoever and did not even answer any e mails, so we have been left to work out the solutions for ourselves. I will report again after we have finished the repairs and test flown her.

Eventually ZAC had to send me a mount without that bolt hole drilled in the mount, which I match drilled to fit. This was with the Stratus conversion. I don't know if this was an ongoing problem or if it was a on off poorly made mount...I do know my studs were in the right place...:) FWIW.

I assume the same would be true for 601's. Can anyone tell me what size and weight bungess ZAC supplies in their 601 kits? Could I go heavier? and, if so, could someone make a reccomendation? I have a feeling I'm going to have to replace them on the plane I'm looking to buy. They were new in 1996... Been in/on the plane since '99 with an 0-235 hanging off the front. Is it a big job to replace them??? ________________________________ Message 13 ____________________________________ Time: 02:23:02 PM PST US From: Jack Russell Subject: Re: Zenith-List: 601XL Flap Actuator Travel --> Zenith-List message posted by: Jack Russell scott: My ZAC supply flap motor has a screw travel of 64mm.

I joined the wing panels last weekend and the rear spar plates Monday. I now have to attach the front edges of outter and inner wing leading edges and make the trim strip fit (somehow). Does anyone have any ideas or tips on how to put the flat trim strip around a curve with a taper on one side like the center section and outter panel. Looks impossible. I have thought about fabricating a face plate of fiberglass rather than the aluminum strip but don't look forward to the extra work. Input appreciated and pix would be very helpful.

I'm selfishly hoping that wasn't the reason, since the holes in my mount didn't line up exactly with the firewall holes (part my fault, and part that the plans changed during the building process). I had to tension two of the legs fairly significantly to get the mount installed. Guess I'll just keep a really close eye on it, and include that as part of a preflight inspection. I'm also thinking I'm not the only one that had to install an engine mount under tension, so others may want to adopt the same inspection.

We thought the same thing (several times) during the building of our Kit, but we always got to the conclusion (sp?) that the systems will resist the normal and a little heavier than normal force applied to the controls (and all the plane). I am sure that any one of us will never apply (flying the plane) enough force to brake in that direction (cut) the rivets or the fairleads... I think that probably (My opinion only) the structure (aluminum from the plane) could fail first that the rivets... If we beguin thinking that Superman is going to fly our plane (and with a push or pull could easyly brake it), we will not be able to meet the Sport Pilot weight with all the extra reinforcements we can think off :-) :-) :-) We learned a lot building our 701 and continue learning now with the 601 XL. Mr Heintz IS a Great Designer, no extra weight designed in his airplanes, were is not needed. Remember "Only Add Lightness and Simplicity" to buils a succesfull airplane and make it fly better. Believe me: Since the first piece of the 701 we assembled, we thought that the aluminum was so thin and the plane could brake in the air. Even a friend once (as a joke) brought to us a rol of "Reynolds Wrap", "here is some spare, in case you ruin some part of your kit" he said laughing... Saludos Gary Gower. Tomorrow the first XCountry of our 701 to the Pacific Coast. From 7,500 ft ASL (to cross over our Lake's hills) to sea level in 1.5 hours (depend of wind) following the Ameca River... Will post some photos and comments next week. --- "Hinde, Frank George (Corvallis)" wrote: > --> Zenith-List message posted by: "Hinde, Frank George (Corvallis)" > > > This is a good discussion...Is anybody at the point where they could > determine how much slack the would be if the fairlead dissapeared? > > I do remember being concerned that a slack cable could bounce out of > the > slot in the fairlead so I drillied to tiny holes in the "Lower legs" > of > the slot and safety wired across the slot.

(One step at a time) --> Zenith-List message posted by: Gary Gower This is the way all the airplanes (ultralights and light planes) are tested in our Club, with several (at least 3) slow and (5)"not to slow" taxi tests, just to "feel" the controls before attempting to crop fly to the half of the runway several times, before atepting "the pattern", once up, they keep flying for about 15 to 30 minutes always high and at glide distance from the strip, all other pilots stay in the ground to leave the strip free in case of an engine failure, also to enjoy the happiness of the builder and t est pilot... Once the succesfull landing is done, the date for the barbacue party is "calendared" :-) I think that going up on the first time, without previous experience on type was the big mistake with this unfortunate pilot, we will never know, but I hope his life helps to save more lifes of another pilots.

That's exactly what I was looking for. 2 and a half inches - wow, that's a less that I was thinking. I almost bought the wrong actuator - Thanks! Did you post a photo one time showing the travel on the outside of the fuselage? If you can direct me to that photo I'd appreciate it. Thanks again for the help. Scott. ----Original Message Follows---- From: Jack Russell Subject: Re: Zenith-List: 601XL Flap Actuator Travel --> Zenith-List message posted by: Jack Russell scott: My ZAC supply flap motor has a screw travel of 64mm. With that I can get a flap deflection of about 33 deg from stop to stop. Is that what you are asking? Jack in clovis CA Scott Laughlin wrote:--> Zenith-List message posted by: "Scott Laughlin" Hi guys: I have a question for those with the 601XL flap actuator installed. How far does the actuator actually move. It looks like 3 to 4 inches - the distance between limit switches. I'm in the process of selecting an actuator for this purpose and I need to specify the stroke.

If you can direct me to that photo I'd appreciate it. Scott. Scott: I remembering seeing that picture and I went searching when I was doing the flaps but could not find it. Just don't drill your control tubes until you have the flaps and motor mounted on your plane. I drilled a pilot hole completely through the Actuator arm (remember to position the hole so the nut and bolt heads clear the rear channel both up flap and down position) mounted flaps in the full up position and then drilled through the actuator holes into the top of the control tubes. Took everything apart, clecoed the top holes, and turned the assembly over and drilled the bottom of the control tubes. Took a day to think about it and 20 min to do! Sounds more complicated than it actually was. I think your flaps will be more accurate if you wait to drill your tubes until everything is mounted to the wing. Hope you haven't fastened the baggage compartment floor yet. I got tired of taking it on and off so I split in in half and mounted the back half but left the front removable for now. I also rebuilt the center support (where the two pieces meet) for a little more strenght. It is also easier to install 2 smaller pieces than that one large piece.
