Doing some hanger flying this morning at the local EAA hanger, the subject of flying off the initial hours on an ELSA came up. There seemed to be no clear consensus of what determined a "Certified" engine/prop combination. I have Googled all over the place this evening, and am now even more confused than I was! I have visited lots of locations, as well as the FAA pages. The best I can come up with is that it is up to the judgment of the DAR, who signs off on your project as airworthy. I did find some information that says the DAR may be willing to listen to arguments about 25 hours of test flight time, provided you can prove your engine/prop combination has been FAA approved on other aircraft, in the same combination. I also noticed that there are both approved and unapproved RoTax 912's out there. One of the guys this morning said he was flying the unapproved one so had to fly off 40 hours before he could take up a passenger, but no one seemed to know what the difference was in the engines. The only difference he came up with was a several thousand dollar higher price tag on the approved one! I am building with the Jabiru 2200A, the latest version with hydraulic lifters, and using a Sensenich W62HJ-36 prop. How do I go about finding out if this combination has FAA approval? I believe that combination does exist in some of the recently approved LSA that are coming on the market. Does that constitute approval?

From: "billmileski" For what it's worth: I used Goodyear fuel injection hose (very expensive it turns out), but what I liked about it is it has a high tech core which is supposed to be resistant to auto fuels with the solvents and alcohols. I assume (and hope) it's okay for 100LL also as I will probably have it in the fuel system from time to time on longer cross country flights. The hose seems more rugged and less likely to kink, probably because it's rated for the higher pressures of injected applications. I think the stuff I am using is this: http://www.goodyearbeltsandhose.com/cars/inject.html By the way I have an Andair mini gascolator, and although the primary (larger) o-ring is supposedly nitrile (which I thought was really tolerant stuff), it has shown to be swelling oversize, and I already replaced it.

Like yourself I have always been thrilled at even the sight of the 601 on amphib floats. The down sides to the configuration as I see it are. If you are going to remote places with large rocks forming the shore line beaching the plane could be a problem. Docking at wharves that have hand rails etc could be the same problem. pumping out the floats if the plane is still in the water could really be an aquatic (swimming) event as would be loading float lockers. Carrying anything on the struts would be a non event. All those items are, to me, primarily convenience features or inconvenience features. I think you will find those who are actually flying their 601s on floats must really like them.... there are enough of them out there. If I can ever come up with the cash I'll order mine the same day..... After all I still have the "Fox" to get in and out of the rough spots.

You need a good set of pants, gearbox fairings, step tube fairings, a full core spinner, a 17 inch pitch in a 70 inch prop, a clean aircraft and 100 hp to get there. There's no magic, just persistent effort at cleaning up the HDS. The latest finding was that the elevator trim at the highest speed needs to be readjusted to allow the lift to move further back and that last adjustment reduces drag a little bit more. I believe the HDS might be capable of even more with adjustment of the prop, trim etc. In any case, the XLs thin wing will do better with the same effort, etc. Read my journal section 11, December 27 and the latest GPS airspeed check and you see that it's possible if things are in proper adjustment.

Let's face it, a "One size fits all" bend radius precludes individual stress calculations. By the FAA recommendations, .125 is way overkill for .016 stock, but nearing the limits for thicker stuff. Just for kicks, find the thickest material on the plans bent with a .125 radius and apply the FAA calculations. If I were to draw a simple to build design, I'd calculate to 2T of the thickest material for a safety margin and have all the rest of the thicknesses overkill. That's my RATIONALIZATION, not an expert opinion. I remember that some of the "What do you do" respondents were aeronautical engineers, while I deal with plastics.

My take on the standards specification is a minimum radius for the material. I would interpret this as an absolute minimum. The designer's specification should take precedence over this standard. Chris's 1/8" radius should be considered the higher priority. We can assume he based his structural calculations on this radius rather than the minimum specified in the FAA circular. The other side of this coin is the designer certainly included a considerable margin in all his limits for the design. That means a small variation from the ideal measurement should not make the design unsafe. These planes are meant to be built by first time builders, so the tolerances are generally very loose and the strength margins can be presumed to be high. I don't recall reading about any tolerance in the .125 inch bend radius in the builder's instructions, but I am sure this is not a critical measurement. Still, I would strive to meet this bend radius in all of my parts. The bright side of this is once you set up your bending brake or other equipment to bend parts you will build in the bend radius in the tooling. Then you can mostly forget about it.

I am still waiting for some good data on the cruise speeds achieved with the Jabiru on an XL. Since ZAC reports faster speeds for the XL than the HDS I am hoping for numbers in the 160 mph range.

I graduated a physics (electro-optics) major some 18 years ago. Didn't find a job that paid enough to play with lasers and make holograms all day long, so ended up an electrical engineer (power systems), working for a small consulting company. Right now I am working around JPL's big dishes that talk to the little skateboards on Mars and to the space probes! My expensive hobbies: I am an amateur photographer, private pilot, archer, hiker and mountain biker. And am working on lifting my second Jeep Cherokee for desert racing. After taking the RV builder's class I came to the conclusion that Zenith is a lot easier and quieter to build in a metropolitan area!!

Recently picked-up from Zenith factory the newly released FWF package and a Rotax 912S. When following the instructions on mounting the new Ring Mount to the 912S I determined the water pump housing hose nipples for the left side of the engine (from the back) are positioned such that: 1) the mount cannot be reinstalled due to one of the hose nipples hitting one of the structural ring mount brackets, and 2) the other left side hose nipple does not provide for adequate clearance/routing of the connecting hose. The Heavy Maint manual indicates these hose nipples are held in place with Loctite 648 and the part needs to be heated to 180F in order to remove the hose nipples. I am at a loss on the best way to complete this task. Do I take a small butane torch and heat the area directly around the hose nipple? Do I place the water pump housing in the oven and heat to the desired temp? Do I take the housing and put it in boiling water? My fear about the torch is somehow warping the housing by the uneven heating. Anyone have a suggestion, or have they faced a similar problem? Will also send a request to Zenith Tech Support to see what they suggest.

I think a hair dryer might work if it gets hot enough. It is going to take more than 180F though. I heated the whole fitting up evenly and when I felt the adhesive become pliable, I gently moved it into the needed position using a wooden dowel inside the fitting. let it cool. No problems.

I was thinking I was three weeks from taxi tests last week. A very experienced new friend of mine told me I was still three months away. That was after I had a breakthrough weekend thanks to his help. I hate to admit it but; I think he is right. Make a plan that works for you. Modify it as is needed. Try to do something on the project every day. Remember that someday you will fly this thing. It sure is looking better today; but only because I did something yesterday! I did not get as much done today as I had planned; but I got a lot done. I have plans for tomorrow as well. I have passed the point that quiting is not an option. I WILL FLY THIS THING SOMEDAY.
