What will its performance be? Will it be available as a kit? Will you be able to build it from plans? How close is it to the 701? In other words, does it share any of its construction? How will it compare to the 701 in terms of cost? I have little doubt that there are many new or potential 701 builders with similar questions. Thanks in advance!

I have a couple of questions from those that have painted their own planes. 1. The prep on the outside. Scotchbrite and wipe down with MEK or lacquer thinner? Is there anything else? 2. What type of primer is everyone using? I think I want to use a Urethane paint. Any primers and paints that anyone would recommend? What is the max time that you can wait to put the finish paint over the primer? 3. I see some paints have a clearcoat over the paint. Any experience with these, are they necessary? I have seen some articles on a paint booth and respirators. I am really interested in the actual painting process. Any help would be appreciated.

I made wheel fairings that were narrower than Zenith's, but the same length. I was happy with them until I did a side-slip with them. The slip was a lot less effective, and I had a very loud noise of dirty air from the noseweheel fairing plowing through the air. I'm curious to see if your shorter fairings don't have this issue. Let us know how they work. Thanks!

If it were just the product shells from the mold, I'd need not much more than $150 and the buyer/builder would have to put them together, do the finish work and provide hardware from a set of drawing templates. If I had to do the total assembly, finish to prime, they would have to cost more. It'd be nice to find someone that likes fiberglass work enough to do several at a time. We'll have to see how the first sets come off as soon as I get another intake done for the radiator.

I figure if the scratch building becomes too much to handle I can always revert to the component kits. After a bit of looking though, it's looking more and more like the STOL701 would be an easier build. The fuselage seems a lot more "boxey" and such, which I would guess makes for easier construction. Being a first time builder I'd really like to start off with a project that I think I could finish with as little difficulty as possible. So, to the experienced people on the list, is there any difference in difficulty as to building the 601 vs the 701? If there is I may elect to set the 601 plans aside for now and instead go with the 701. They both look like good airplanes. Thanks ________________________________ Message 11 ____________________________________ Time: 12:08:00 PM PST US From: Larry McFarland Subject: Re: Zenith-List: Article --> Zenith-List message posted by: Larry McFarland Bob, There are lots of discussion within the archives on your questions and the Kit Planes magazine has specifics on booth, filter construction, prepaint and finish work in the last three issues. Back issues are available at their site. I'm in the same position as you with a 601 needing paint soon. Check out ch701.com and ch601.org sites for breathing apparatus and filter construction.

Being able to draw upon the knowledge of another builder who is local can be of the most value in your decision.

The 601 is a good cruiser for cross country and visibility is great. The 701 is a flyer's aircraft that won't satisfy any long cross country, but it's great STOL. There isn't a great difference between them for the scratch builder, so take your pick according to your perception of what kind of flying you do. They both employ the same box technology, but the 601 flaps and ailerons seem simpler.

The fairings for the wing came from Sky Shops and the Jury Strut fairings came from RANS. My friend Tim glued them on instead of riveting them on.....he did however rivet the back edge of the lift struts. Time to install and paint came to 15.5 hours. Cruse speed with my 70" 3 blade warp drive set at about 12.5 degrees on the tip went from 90 to 95mph with a stock 912S at 5200RPM. Next project will be to put on the Sky Shops Retrofit kit with the rotax airbox and new cowl. I'm hoping to gain a bit more before slowing it down with floats. I'll report on the retrofit kit next. So far so good. I am not affiliated with Sky Shops or Rans.

You need a different forming block for each one. The 701 has a straight wing so you can use one forming block to make all the ribs in each wing. Other than that I don't believe there's much difference in the difficulty between the two types. However you can order the wing ribs or any other individual parts from ZAC. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. do not archive. ________________________________ Message 21 ____________________________________ Time: 04:21:03 PM PST US From: Larry McFarland Subject: Re: Zenith-List: New wheel fairings for HD HDS --> Zenith-List message posted by: Larry McFarland Ron, Today's entry to the journal section 8. I was also very curious, so this morning I took the time to get a better idea of what might be gained. Also, if I did more than furnish a set of shells and instruction sheets, these would also be near that price range. It's not hard work, but it does take time. * June 19* Father's day was a calm and sunny morning. I went to the hangar and did a thorough preflight inspection, topped off the plane with 87-octane fuel and checked the wheel fairings. I took off from runway 31, climbed 80 mph at 4800 rpm with the propeller set at 16-degrees. The rudder and elevator inputs seemed a little slippery. I leveled off at 3000 ft to an ambient temperature of 76-degrees. At 4000-rpm the plane eased past 100 mph, at 4200-rpm, airspeed climbed to 105, at 4450-rpm airspeed passed 110 and 4700-rpm brought it to 115 mph, and 5100-rpm put airspeed just over 125, and more importantly, all engine temperatures stayed within limits. I ran the four main compass headings on the GPS with these settings and came back to average these. After spending a little more time in realistically evaluating past performance, the pitot driven airspeed seems to be within 1 mph or dead accurate with the GPS. I believe there's not more than 3 mph gained at top end, but there's a 6-mph improvment in mid-range cruise between 4200 to 4800-rpms. In any case, the plane performed really well, but for what seemed like a faster approach and longer rollout. To get a better handle on that, the fairings will stay on until it's time to paint. ron dewees wrote: >--> Zenith-List message posted by: ron dewees > >Hi Larry, >They look great.

This was not the case with the new ones, but there is a slippery feel in the rudder that wasn't there before. I've not been inclined to do slips because the HDS sink rate increases as quickly as the airspeed drops off, so one has to keep an eye on what's going on. I've been surprised by the sink rate while turning a steep bank onto a final approach, and I'm not going to repeat that one either. If you had a HD, the float might be more forgiving of the slip, but loosing altitude has not been one of the HDS's problems. I did gain a good 6-mph at midrange airspeeds, but only topped out at 3 mph over privious wide open throttle. Temperatures didn't get out of range either.

I was happy with them until I did a side-slip with them. The slip was a lot less effective, and I had a very loud noise of dirty air from the noseweheel fairing plowing through the air. I'm curious to see if your shorter fairings don't have this issue. Let us know how they work.

I read the Gary Wolf article (at www.ch701.com) and in it he states that a prop less than 68" won't perform in a 701. I would be interested in why he thinks so. Why is a long prop better than a short prop? Seems to me that with a shorter prop you just give it a little more bite, same end results. Thoughts please.

I can no longer remember enough of the conversation or facts to prove this point but I'm sure Gary can. Write him at wolfpack@sentex.net and let all of us know of his response.

I ordered my firewall forward package from Skyshops and it should arrive soon. I SHOULD have ordered the strut fairings too. Hind site is 20 x 20. That's why I was wondering if anyone fabricated their own. I don't want to wait several months before they arrive, I would rather purchase locally or fabricate ones if I had a plan. Are the ones from Skyshops an extruded aluminum strut/fairing combo that replaces the strut tubes or do they go over the existing strut tubes? The article said someone fabricated ones out of .016 aluminum sheet. I am hoping that the wait for the firewall forward package will be worth it as I am unable to proceed much further until it arrives. I am using the 912S with the Woodcomp 3 blade Klassic. From the article that seemed to be the right choice. Bob Spudis Do not archive
