    Welcome to the family.

    I wish you the all the best with your project.

    If you ever get the chance to visit the Zenith factory please take the time to stop by our builder assist facility too. We like to have visitors here and we are right here in Mexico, Mo. just a couple of miles from them.

    Take care and good luck,

    Nelson,
    Welcome and good luck with your project. Regarding hanging parts on the wall, be careful if the wind blows through like in my garage / basement moving the pieces they will scratch easily.
  • Paul

    Hi Nelson, I do not have a list for the 701 but Zenith does. they do not have a list for the 750.

    Hey Nelson

     Welcome to the "minority" as nobody fly's two stroke engines in the Zenairs anymore. I am building to the specs of the original 880lb empty and have the original landing gear that bought used from another builder. I live in a small Isalnd and I am not going very far, so to me it's ok the little engine and I know it's going to perform as papa Chris desingned .

    Saludos

    Another thing Nelson

     Plan on buying additional material as you will make mistakes, in the case of .016 they are very easy to wrinkle. Out of .025 is where a lot of critical parts come from so consider bying an adittional one in case you are not happy or the part does not meet spec's. The R503 is my second choice if the snomo conversion does not goes well, but the 582 is very good.

    Hey Nelson, here is the info I sent to another builder.

     

    I was concerned about the solid rivets myself. Never having done any before. I bought a manual rivet squezer (way to hard) can be used for dimpling. I bought a Habor Freight rivet gun (can only be purchased online) http://www.harborfreight.com/3x-air-riveting-hammer-with-5-piece-ch... .

    I used the 20% off and that paid for the shipping and tax.

     

    I also purchased the economy rivet set from Aircraft Spruce http://www.aircraftspruce.com/catalog/topages/topcanrivetsets.php 

     

     

    These are better quality than what comes with the tool. I used the one with the tool and it damaged the surfaces easy. The one from aircraft spruce worked great. It fits the heads better.

     

    I practiced on about 50 holes. I set up the same thickness for practice.

     

    The jig set the spar height. I drilled the lower spar cap and clecoed. Then I measured the spaceing for the spar and drilled the the upper spar cap at one end. Made a jig of that spacing. The moved down the spar and drilled the caps between the jig. The next spar will be the same as the first. I pre drilled my spar caps.

    I ordered my big sheet metal order from Yard Metal out of Conn. I saved about $500.00 fro everywhere else. I had problems with UPS freight, but it worked out in the end. Not sure what the prices look like now.

    Thanks Nelson!  Semper Fi back to you as well.  My nephew is also a Marine and we were both here together lasst June/July yet he was shot up pretty bad on his last patrol before going home.  I spent 12 hours with him before he was shipped to Germany, kind of sad but the Marines make you guys pretty tough and he pulled through after about 4 surgeries.

    I am very eager to get started!

  • David DeAvila

    By the way Nelson, this is the link to the story about my Marine nephew that was shot up. My son is the tall one on the left in the rear. He did 2 combat tours in Iraq with the 82nd during the surge.

    Hi Nelson,

    Welcome into the group. You asked why build a CH701 if I already co-own a PA-28 160 Cherokee ??  Quite a few reasons not in any particular order :

    1) I started building the CH701 before my partners and I bought the Cherokee and

       I tought that I could fly something and take my time building while flying

    2) I liked the CH701, easy to maintain, easy to fly, easy to construct, cheap to fix

    3) my wife wants to take her lessons (shes flies the Cherokee pretty good with supervision) but can't do it on the Cherokke - she isn't a co-owner

    4) She and I will own the CH701....so she'll take her flying lessons on it

    5) I kept my share on the PA-28 because I just LOVE this plane, fast, reliable, lots of room for luggage and I just pay 1/4 of all costs (4 co-owners). A bargain !

    6) Each plane has a very different purpose : ch701 for rooming around and the PA-28 for fast cross country.

     

    That's the story.

    Good luck with your building !

    Hi Nelson, regarding your question about the performing of my 701 with Rotax 582, I can say that it flies quite well, but some more power would be welcome and less consumption also! Unfortunately, the 582 "drinks" a lot, about 25 liters/hour for take-off and climb, and 15-20 lt/hr for level flight. The great advantage of a 2-stroke engine is its light weight and - at least here in Brazil - the payable price. 

    Regards, Sergio

  • Paul

    Hello Nelson, about the A4 and A5 rivets. there is a dash and number like AD4-5, or AD4-6. the dash 5 or 6 means (5 * 1/16) 5/16 or (6 * 1/16) 3/8.. Same for the AD5's just add a 1/16 of a inch for each increase.

  • Thomas Jackson

    NELSON-----

    Thanks for the endorsement.

    I don't like the thought of bending something that my heart has gone into, so I would like to get maybe 1-2 hours in a 701 just so there are no surprises.

    Nelson------

    Thanks for the encouragement, especial since I haven't found anyone locally (within 100 miles) for the transition. One follow aviator in Canada might be a possibility in the fall, if I don't jump out of the nest before than.

    Hi Nelson (you can call me 'J.')

    Easy... I started with the fuselage!
  • J. Davis

    Thanks, Nelson. Yeah, I've got the DVDs, they're pretty good. But in this particular case, the assembly manual was actually more helpful than the DVD. Anyway, got it fitted perfectly, front fuse attached, no problem.
  • Normand Lambert

    Hi Nelson,

    Brake handle on stick is for the Amphibious float brake system. It is old school drum brakes in the floats main wheels. It was put on the passenger side stick only temporarely. Goes on pilot side when on floats.

    Regards,

    Norm

  • Normand Lambert

    Hi Nelson,

    Yep, Now you know why I needed the twin sticks instead of the middle stick. I needed the space and the center console for the throttle quadrant, radio and some other switches. It was either that or twin controls on the instrument panel. I liked this arrangement better.

    Regards,

    Norm

    Nelson,

    Thanks for the comment- I really enjoyed the building process.

    Welcome to the club!!  You might want to talk to John Rizzo,  he lives in Oley and is scratch building a 701.  I have not talked to him but I believe he is almost finished  building his 701.  I'm retired and started building in January.   I have the tail (rudder), elevator, most of the wings, rear fuselage and part of the foward fuselage completed.  Hurt my back a few weeks ago so not much getting done lately.  Hope to have everything finished and ready for final asasembly less engine and interior by the end of next month.  Have to get hold of John,  I'm sure I'll need some help for the final assembly.  Need any help/advice let me know.  Have fun

    hey nelson the bungee is on the 701 to hold the cables away from eachother as you get to the controls you will see the bungee
  • RANDY L HALLOCK

    Hi Nelson, thanks for reaching out, this is going to be a fun project for me.
  • Normand Lambert

    Hi Nelson,

    Thanks for the comment on the instrument panel...Just got to be careful and plan ahead...Now That I think of it, I don't know if I wouldn't replace it with a glass cockpit ???

    Naaaaaa, I like the round gauges !

    Regards,

    Norm

  • Normand Lambert

    Hi Nelson,

    Nope, the engine sitiing in my CH701 is an EA-81 1800cc 73hp in its stock version.

    Mine has been reworked and is supposed to develop 105hp. We'll see about that soon enough. It is lighter than the EJ-22 /25 or even the EA-82 and less complicated.

    I see you're getting ready to do serious work !!

    It's feasible ! Just keep at it !

    I have a list. It is only a list of all the parts though. Not everything is stated as to what it is made out of. You too can get this list off the Zenith web site.

    Gidday Nelson. re yr comment about cowl layup. I cut 6 thin MDF profiles  and a round piece the size of the spinner plate & taped them to the firewall at the rear & prop hub mount to give me a guide to the shape I wanted. I then scrunched up news paper and stuffed it around the motor/gearbox etc to fill most spaces, then taped 1" styrofoam sheet between the MDF profiles to roughly fill the remaining space. Then the fun part, squirt expanding (plumbers) foam in to fill the remaining gaps which also acts as a glue to the MDF & styro to hold it all together. Use breadknife & surform rasp to roughly shape. Then add more foam in any holes and do it again until you get the desired shape. Be sure to mask any areas you don't want stuck with foam and don't leave gaps where the foam can enter to stick to the engine exhaust etc. Lastly cut the top part along the line that will make a top & bottom part and prize it off. That's where I'm up to. I am going to use plaster of paris to smooth over the foam and then spray this with auto body putty to give a smoother surface, then spray paint with auto paint and finally give it to a fibreglass shop to spray on release agent and chopped strand mat to make a female mold. Then it's back to me again to lay up a fibreglass cloth cowl in this mold, make a join line joggle etc for Dzus (or whatever) fasteners and thats it. Well thats the plan anyway........................ I will take pix of separated cowls and post on my site later today.  Hope all this helps. Cheers, Ian

    Hi Nelson,

    Thanks for the 'Husky' comment...The owner of the hangar called me today and told me he coudn't believe how a coat of paint and some trim could change my plane so much. Me neither for that matter.

    Norm

  • Normand Lambert

    Hi Nelson,

    you are right. It is a Subaru EA-81 that originaly was rated at 73hp. It was reworked (porting, head work, timing...) and was tested at 105hp on a dynometer.

    Hi Nelson,

    Thanks for your comments. I'll post a video as soon as it takesoff !

  • Normand Lambert

    Hi Nelson,

    Hard to say but getting closer...Carburator tests over the weekend, adjustments and then Taxi tests. Before year-end for sure !

    Cheers.
