    Subject: 2 piece canopy , 601
    --> Zenith-List message posted by: "Rick Tedford" <rick.tedford@sympatico.ca> Hello Listers : Has anybody seen or know of a 2 pce. canopy design for the 601 . Obviously the slider type would not work , however , perhaps a semi slider would . I am thinking that a rail at the back , plus a pivoting arm at the front may work .( 1 on either side of the moving portion of the canopy ) The sliding rail could be the same as found on the RV-9 and the pivoting arms should be long enough to allow the canopy to go back far enough for easy entry . This would allow for roll over protection by the inclusion of a frame similar to the RV. Possibly there are other concepts that would work Cheers Rick

    Subject: Re: 701 Firewall Fwd. Skyshop or Zenith ??
    --> Zenith-List message posted by: RURUNY@aol.com I have the Zenith firewall fwd kit and everything in it has worked out well and fit fine. I looked closely at the Skyshops kit and it looks like you get a lot more for your buck even though it is more expensive. It has a modified airbox that will work with a 701, a nicer looking better quality cowl with naca scoops on the side for air intake into the airbox. Zenith is using K&N filter right on the carb. Looking at the pics on their site, you even get a standard throttle setup for the pilots side. Even the way the oil tank for the 912 mounts makes more sense and gives you more room for a better cabin heat installation. The Zenith engine mount and associated parts and muffler were of very good quality, I'm sure skyshops is the same. Skyshops has lots of pics that you can zoom in on to look at what you're getting, Zenith does not give you anything to look at, so what you get from them now, could be different than what I received 3 years ago. I ordered a 912s firewall fwd kit from Zenith and received a Warpdrive prop. Is the extra $522 is worth it ? IMHO yes. Brian Long Island

    Subject: Re: 2 piece canopy , 601
    --> Zenith-List message posted by: "Edward Moody II" <dredmoody@cox.net> Could you build in a rollover protection bar immediately behind and above the passengers' heads that the canopy would rest on when closed? It should only be a weight issue since it would be very near the CG. If strong enough to work as a roll bar, it would also be a convenient site to anchor the harnesses and provide a handhold for entry and exit.

    Subject: Firewall Forward from Skyshops
    --> Zenith-List message posted by: Mark Sherman <msherman95632@yahoo.com> The Zenith 701 firewall kit is $3928 and Skyshops is $4450. Any opinions on which kit is better? I'm about ready to order and would like to hear all advice about which one I should purchase. Thanks Larry Bohannon Winder, Georgia Larry. I purchased the FWF kit from Skyshops. They saved me more than the difference in price form Zenith with a discount on the engine when purchased at the same time. Zenith does not support (at least at the time I purchased the kit) the 912S to get the 100 hp. Zenith has you putting K&N filters right on the carbs and doing away with the supplied Rotax air box. The Rotax air box has connections for carb heat and cold air intake, which helps you get the 100 hp. Using the hot air from inside the cowling reduces the horse power. Almost the same as running with the carb heat on. We all know what that does for power! The Skyshops cowling is more streamlined with less drag, which they say gives you about another 10 mph, we'll see about that. It also has a NACA duct for the cold air intake which force feeds the intake system. After working in the aerospace industry and seeing the way things should be done, I am disappointed in Zeniths willingness to upgrade manufacturing and kit quality in the older designs, the 701 in particular. They had the opportunity when the upgraded to the SP to CNC cut and punch all parts and holes to make this a kit that could truly be built in 400 hours and only ad about a thousand dollars to the kit price. I would have gladly paid that extra. I am at about 1200 hours and still need to paint and assemble.

    Subject: Firewall Forward from Skyshops
    --> Zenith-List message posted by: "Allen Ricks" <allenricks@verizon.net> Mark, I have to agree on the CNC punching. If Van decides to put out an LSA aircraft, they will put the 601 out of the picture over night. Van CNC's all new kits now, and Zenith would not stand a chance. Weird that they decided to do the 601 QB kit by hand, rather than investing in new CNC stuff for their whole line. That being said, the staff of Van's sounded like they really weren't sure if they wanted to do an LSA, but they said that about the 4 place RV-10 also. Allen .....

    Subject: safty of flight
    --> Zenith-List message posted by: john butterfield <jdbutterfield@yahoo.com> Hi guys, I have just about finished my wings and starting on the fuse. I have followed this list for about a year now and am pleased with all of its contents. One thing i have noticed is the lack of discussion regarding angle of attack instruments. I know most of you that were trained in the military are aware of the value of the AOA, but it seems that this one instrument is so important for safe flight, i though i would get on a soapbox and voice my opinion. If i had a choice between my airspeed indicator or my AOA failing, i would certainly choose the AOA as my primary speed indicator. After a few hours in our machines, we know about what the speed will be at any given power setting. When in the slow speed mode, the a/s indicator is fairly unreliable. the AOA is never wrong, (assuming is is set up correctly) it will always indicate the best speed for any weigth and atmospheric conditions. Actually, ater you get used to it, landing become very precise and at the proper speed. When i flew (USMC)in military aircraft, we usually added 10kts for the wife and 10 for each kid. Of coarse this is a joke, but landing at the proper speed is safer and much easier on the aircraft. Short field landings, are the norm (if desired). I only feel confident in giving advise to this group regarding the AOA. I am humbled by the knowledge you have regarding building and flying the Zenith products, I would put the AOA as the best insurance for safe flying. It works all the time and should be your primary stall waring devise in all aspects of flight. To those who have not used an AOA, take the time to try one out. To those who have, your opinions should be voiced. Kinda feel the same about auto pilots, but that's another soapbox. best regards to the group. john butterfield 601XL/corvair

    Subject: Jabiru carby enonomy kit results
    --> Zenith-List message posted by: "Paul Hartl" <paulhartl@cox.net> Hi List, I finally took to the air with carby economy kit installed in my Jab 3300A-powered HDS with the following results: cruise @120 mph TAS @ 2750 RPM: 5.5 gph cruise @110 mph TAS @ 2550 RPM: 3.8 gph wide open: about 127 mph TAS, ~3000 RPM, ~7 gph all @ 7000' msl, and about 5 C (40 F) OAT full power climb: somewhere around 7-8 gph, yielding between 1200 to 1500 fpm from 6000' to 7000 msl' (solo, and about 10 gals fuel) So that last 17 mph almost doubles the fuel consumption! - Which is pretty much what Jabiru says in their literature. These numbers are not as precise as I would like them, as I find it difficult to keep track of airspeed, RPM, altitude, track, and fuel consumption - all while looking out for traffic. But I think they're within 10% of correct - probably. All in all, I'm very happy with these results, as it has cut my cruise gph by about 50% - from about 6.5 to 4 gph. For Jab owners wondering if they need this kit, you will make up your $85 investment very quickly at $3.30 a gallon, and it is a pretty easy kit to install - if they remember to send you the directions!

    Subject: Rudder Attach brackets
    0.15 HTML_TEXT_AFTER_BODY BODY: HTML contains text after BODY close tag --> Zenith-List message posted by: "Matt & Jo" <archermj@swbell.net> Hello all, Finished up the wings and have started the fuselage. Has anyone had problems with the upper rudder hinge 6B2-7. I have yet to drill, but when laying it out I noticed that there is no way to maintain a 2 d edge distance with a 1/4 hole and maintain the 11 mm spacing. I noticed that the latest revision to the drawings have increased the thickness of this part from 1/8 to 3/16. I have emailed ZAC and am waiting for their reply. I am not sure if I just got a bad part or what. Has anyone put the access door in the bottom of the fuse. Is it needed? Cheers Matt www.zodiacxl.com

Now its time for more flying, not building (although I do need to paint it!).
