    Subject: Stratus Alternator - Backup Ignition - Reverse Throttle
    --> Zenith-List message posted by: Andrew SanClemente <ansancle@townisp.com> Does anyone have a part number to replace the alternator that comes on the stratus motor? I would like to find the same one so the wiring and mounting brackets all line up. On my alternator it says "NIP P/N 14684" but I can't get any hits on that when searching. Also, my backup ignition is junk (never worked), looking for options to replace that, again - reusing mount points and wiring most desirable. So if anyone has part numbers etc. it would be greatly appreciated! Last - My throttles on the Bing Carbs are setup in such a manner that when the arms are deflected fully down its at idle, full up is full throttle. This results in having to pull out for full power and push in for idle, opposite of what it should be. My springs pull to idle, not full power as I guess was intended by Zenith. Any suggestions?

    Subject: Gas Struts
    --> Zenith-List message posted by: Mark Sherman <msherman95632@yahoo.com> Larry Martin. I just finished the doors on my 701. Per plans, probably lighter than the bubble doors. I used the gas struts available at Aircraft Spruce. They only offer one size, I think it says they are for an RV. They have 45# of force and a short stroke, about three inches or so I think. Because of the short stroke the door has a lot of leverage on the strut so you need the 45# to lift the door. If you used one from a car trunk that had a twelve inch stroke or so, you wouldn't need so much pressure, because you would be lifting the door much farther out from the fuselage. If you would like a picture of mine contact me off list and I will be happy to send you copy's. Mark S. CH-701/912ULS waiting for engine and instruments to arrive. __________________________________ http://messenger.yahoo.com/

    Subject: B.J Schwaller's Zenith 701 N452BJ Flys
    --> Zenith-List message posted by: Monty Graves <mgraves@usmo.com> I am VERY PROUD to report to the group that last evening after a long and much anticipated wait, B.J. Schwaller's Plans built, VW powered 701 made her maiden flight. No surprises with the engine, redrive or plane. A few may remember B.J.'s plane is the first 701 that is powered by a Valley Engineering redrive and 1915 VW Engine combo. http://www.culverprops.com/ Take off roll and acceleration were outstanding as was as expected, (considerablely less than 200 ft.) Climb was also outstanding even with the test pilot trying to keep airspeed above 50 mph on climb out. No bad habits reported and the first 8 tenths of an hour were a non event. The test pilot fell in love with the plane. Flying stall at altitude was reported at 35 mph GPS verified, NO wind, cruise 65 mph at 3000 rpm, which is where the test pilot said the plane felt like it wanted to fly. 73 mph at 32-3300 rpm, 89 mph at 4200 rpm. MAX Full throttle CONGRADULATIONS B.J. A little more information about B.J. and his plane and his contact information is pasted below from his builder page on the Zenith site. Where you can see pictures of his plane and engine. Pictures are also on the Valley Eng site http://www.zenithair.com/bldrlist/pm.cgi?login=B.J.S.&action=display&privat e=& Monty Graves =============== B.J.Schwaller - STOL CH 701 Builder - Finished and Flying last updated: November 4, 2003 Builder Information: Name: B.J.Schwaller Address: Eugene Missouri 65032 United States Email: batrum1@wmconnect.com 1617 hours,15092.77 dollars and It's DONE. Airworthiness certificate issued, waiting for test pilot to make first flight. Final weight 598 pounds including E.L.T. and auxilary battery. Power is a 1915 VW conversion with a 1.61 reduction drive by Valley Engineering L.L.C. of Rolla Mo. Engine weight complete with Diehl case,reduction,starter,alternator,carb., ign, and crossover exhaust system is 180 lbs. dry. Prop. is a 3 blade 72in.Ivoprop Latest Updates: Measured static thrust 362lbs at 3700rpm Why I'm building an aircraft: I like working with my hands.

    Subject: Re: top mounted fuel senders
    --> Zenith-List message posted by: "John M. Goodings" <goodings@yorku.ca> My solution to the problem looks pretty (honestly!), but was rather a lot of work. I made a fibreglass domed cover about 5 inches in diameter with a neoprene gasket held on by 8 #4 little sheet metals screws. I used a chemistry watch glass as a former, but many other things would do. The reason for the fibreglass was, the turtledeck skin is sufficiently curved such that a flat cover simply won't fit. To get the right curve, I put a sheet of sandpaper face up on the turtle deck and sanded the fibreglass to fit BEFORE I cut the circular 3-inch hole (approximately) in the metal skin. This was necessary because I had to get at the calibration screws on the top of the sender after the assembly was complete. Also, being a firm believer in Sod's Law, I'm betting I have to get at the wires/connections/calibration screws on top of the sender at some point in the future.

    Subject: Zenith 701 engine mount.
    --> Zenith-List message posted by: "Johann" <johann@gi.is> Hi list members. I was just bolting the rotax 912 engine to my engine mount and was wondering about the bolts which attatch the engine to the mounts. To bolt the steel E1-1X to the engine, an M10 x1.25x20 8mm key 12,9 hardened bolts are used. But the steel bracket is bolted on the dynafocal bracket E2-1X with an AN4-10A bolt. Hardned 8.8? I am no engineer, but somehow this seems to be a much weeker attatchment than all the others. So this would be the weekest link? Please correct me if I am wrong here. Am I missing something here? Is this strong enough for the force of Rotax 912 80 hp shaking? Just wondering if anyone has thought about this. Best regards, Johann G. Iceland.

    Subject: aircraft lighting
    --> Zenith-List message posted by: louiscfi@comcast.net I am about to order the options for my kit which is to be delivered next month. Just wondering if anyone has researched the pros and cons and the availability of alternative lighting. LED vs Normal nav/strobe lighting. Also has anyone had much luck converting auto HID lighting for a landing/taxi light. I have seen some aviation specific kits for about $400 per light. I really like the idea of HID w/ more light and less heat and the ability to just leave it on all the time, but $800+ for taxi and ldg lights ouch. -- Louis 601xl, corvair pwr j-41 capt CFII SMEL Keep the greasy side down.

    Subject: Spring Load Steering Rods on 701
    --> Zenith-List message posted by: "Larry Martin" <earthloc@att.net> Completed my spring loaded steering rods today. Pictures were sent to the pictures@matronics.com and to www.ch701.com. This setup allows several adjustments that the solid rods do not. The main reason I am using it is because it allows you to push rudder without the front wheel turning until it rolls. This depends on how much tension you put on the springs. Take a look and if there are any questions, I will try to answer them. Them is the same setup I used on my RAF 2000 gyroplanes and it worked real fine then. Of course I haven't flown it on a 701 yet. Larry N1345L Take a look, www.gyrostabs.com ---

    Subject: Re: aircraft lighting
    --> Zenith-List message posted by: Joemotis@aol.com Greetings listers I bought the landing lite/taxi lite kit from Zenith. But, if I was doing it again, I would build it from the plans. There is not much to it. Do not know about the halides but boy ! that is expensive. As for the LED position lites it seems plausible and a lot less amp drain, which is a concern to me with the Jab 3300 20 amp alternator. As for the strobes from ZAC, they say to run them with the lamps disconnected if they have not been used for a while, to charge up the capacitor. How impractical! Not to mention skimping on the power supply components ratings and design. I would never would have bought them if I had known that. The other option given is to charge them at a suggested reduced voltage of three volts for 10 to 15 minutes. That seems the way to go, using a d.p.d.t.c.o. switch with one side turning on a 3 volt power supply to the strobes power supply and the other side of the switch sending (the strobes power supply)12 volts for operation. Can anybody come up with a schematic for the power supply? Ohms law is saying to me it would only have to be one quarter of the amps to charge them then it would be to operate them I think...

    Subject: Preflight experience
    2.6 CELL_PHONE_BOOST BODY: Talks about cell-phone signal improvement --> Zenith-List message posted by: "Larry McFarland" <larrymc@qconline.com> Hi guys, Had to share this Preflight experience Kelly Meiste offered an hour in his 601HD to do flight familiarization and proficiency this afternoon so I drove 45 minutes toWhiteside SQI arriving near 4:00 p.m. We initially talked thru his 80 hours of 601 experiences and first flights. Kelly did a preflight exam and then we taxied out to runway 7, accelerated rapidly, lifted off and flew south while Kelly explained the 601s manners. My first impression was that the acceleration and immediate climb out with two persons was astounding. The Subaru loves to run above 4000 and it sounds much like a well-oiled sewing machine, so sweet! I made a few turns and gained a feel for the 601 as we returned to SQI. The view from a 601 has no peers unless you're a bird and this sunny afternoon was an unlimited horizon. Kelly communicated and broadcast from a dash-mounted Icom AC22 and intercom splitter to headsets. The reception was excellent for aircraft as distant as Davenport 50 miles away. I was allowed to do the next 5 or 6 touch and goes. My initial approach amounted to a steep diving glide to a flare and a solid touch down. But after some patient coaching, I was able to decend while holding 90 at 2500 rpm and then round out a flare that resulted in a reasonably good touchdown. I found that there is enough elevator and rudder authority to land crosswind with a slight low wing and keep the nose wheel off a bit with practice. The plane is much, much more fun to fly than anything I've had the pleasure to be in. The opportunity to fly another's airplane is definitely worth it. It resolves a lot of questions about glide angle, approach, flare, touch down and rollout. This experience will have made my first flight a much safer one and my wife and I are very thankful to Kelly Meiste for that. Most fun I've had in a long time. Thanks again Kelly! Larry McFarland - 601HDS
