Water cooled engines sound better and generally cost less to run and maintain. For a 701 this is a good choice.

Thanks. I have been struggling a little with this 5500WOT business but then I struggle with most everything anymore. I setup my 701/912ULS like JG-for 5800 WOT, straight and level(I figure that's where it makes about 100 horses and since I paid for them I like to use them...or at least be able to get to them if I need/want to) for maximim takeoff /climb performance and minimum idle thrust, and I use firewall power for all takeoffs and initial climb, honoring the 5 minute limit. I generally cruise at 5000 rpm as you recommended. Since setting the prop for 5800 WOT s/l I have done some airframe cleanup and the thing will blow right thru the very low airframe redline before getting wound out to 5800. I have thought about putting some more pitch in the prop to slow the motor down but the plane is already running too fast unless powered way down which is my question for you...at what rpm should we consider the engine to be lugged down? Your premise of "balance"(compromise) I agree is normally what we strive for. The 701 however is such a unique little beast that in my thinking it doesn't really apply, as it would to a 601, for instance. I wouldn't want to give up any short field capability for the sake of balance(or engine life-as long as it'e operated IAW the manual) cause that's what the 701 is all about. Thanks for your info.

What I can't get, is an all up with accessories and extra FI and water cooling paraphernalia weight for the Raven. Ricks plane is pretty heavy, but he is unsure of the exact weight of his various parts. ( no offense Rick, love that plane of yours, but I am wanting as much useful load as I can get. I have to admit that it is a miserly engine with the gas consumption though). I also don't care much for the idea of high pressure gas lines and return lines. I have the system all drawn out, but I'd rather have a simple carb and gravity/low pressure fuel pump, and air cooling. I just like air-cooled engines.

It only happened yesterday afternoon. The pilot was Garry Sweetnam, the Australian Zenith XL Distributer and he was on a VFR flight when it plunged into the ocean off the Goldcoast of Queensland. There were 20 people on the beach who witnessed this. Garry was my friend he was also a LAME and the plane was built in the hanger along side other pipers and cessna's that were being worked on. So this was not a backyard outfit. The plane was VH reg so the Civil Aviation people here (FAA) will investigate and give reports.

I decided that I liked Joe Motis' suggestion (on ch601.org) of putting the electric boost pump(s) in the wing(s), so I started working on that. The nose ribs are different in my wing than in Joe's, so I had to redo the pump channel. I had a few false starts before I came to a satisfactory solution. Then I had to ponder the fuel lines. I wanted to use aluminum from the pump to the firewall, but I couldn't see an efficient way to disconnect the fuel line at the wing root in the event I needed to remove a wing. I considered a rubber hose for the segment from the pump to the wing root. But I have decided, instead, to make a ~2"x3" cutout in the fuselage wall with a cover plate attached by screws and nut plates. Then, I'll put an AN833-6D 3/8" tube x tube bulkhead ell through the cover plate. That way, I can break the fuel line inside the fuselage and, by removing the screws to the nutplates from the fuselage side, I can disconnect the fuel line and the wing from the fuselage. I was discussing this all with Clayton, my EAA technical counselor, and he suggested that I also put the gascolator inside the wing. That is apparently what he did with at least one of his RVs. I liked the idea. I have never liked Zenith's design of the gascolator sticking out the bottom of the fuselage. Back to the drawing board. There were significant problems in designing a system that was maintainable. I've gone through my design process in fair detail on my Kitlog Pro website (see URL below). Check out the entries for the past week or two that relate to the fuel system. Meanwhile, back to the tube diameter question. Bingelis' in Firewall Forward, p. 146, says, "Fuel lines -- 3/8-inch x 0.035-inch for aircraft engines (normally)." That was good enough for me. Also, my tech counselor asked me the horsepower of my engine. I said 120 Hp. He said 3/8" aluminum. I didn't ask why, since that was what I had already planned on--based on Bingelis' book. Did I mention that, in addition to being a pilot and RV builder, Clayton is an A&P, retired after a long career with the MT National Guard. When you get to the firewall all you need is a 3/8" tube x 1/4" or 1/8" NPT bulkhead ell. Then screw a 1/4" or 1/8" NPT x hose adapter into that and attach the hose and fire barrier. Clayton was also worried about how I would implement the tank select valve and pump power switch. My thought is, first of all, to have a pump and gascolator in each wing. Then I plan to put a single pole-double throw-center off switch immediately above the valve handle. So, valve left, left tank. Switch left, left boost pump. And vice versa. And center for all off. I just ordered all the fittings, etc., from Wicks, with the exception of the extra gascolator. I'll get that from Zenith. All this plumbing is not cheap. Think 200 or 300 bucks. Is the peace of mind worth the bucks and the extra 2 lbs of fuel system hardware? That's obviously an individual decision. I suspect most 601 builders would judge me crazy. But at least my tech counselor liked my direction. And, if it all works OK, I'll be happy. Terry At 12:09 PM 3/7/2008 -0800, you wrote: > >John, I am kind of in a similar spot as you.

My reasons for 3/8" are: 1. reduced (significantly) friction losses in the line which means lower pressure drop from the tank to the pump so less chance of vapor lock 2. 3/8" is much stiffer then 1/4" so a more robust system 3. My last kit (Ultravia Pelican PL) used 3/8" from tank to engine (same engine) and it just seems like a good idea to me to do the same on the XL. I am using Swagelok Al fittings for all connections. We used Swagelok fittings exclusively at the Nuclear Plant where I worked (good reputation). The Swagelok fittings come in any size combinations youn can imagine including from 1/4 inch rubber to 3/8" Al. You can Google Swagelok to get your nearest distributor.

If you want better service, I suggest you pick up the phone and give them a call. You'll have your answer much quicker that way. Regards, Larry H Rich wrote: I have an 801 I just completed in December. The 4 seat belts have the 601/701 model number on the tags but it came with my 801 kit. They seem to be too short for the front seats & that's before any upholstory is in. I am sitting on 2" thick foam with 1" foam against my back. They are ok for the rear seats. Are there supposed to be seat belts specifically for the 801 for the front seats? Mine measure from the center of the bolt hole of the rear attach to the end of the first metallic buckle at 805 mm. I asked Zenith about this on Feb 1 & then agon about a week ;ater but still waiting for a response.
