    Subject: re: Aileron end tip...
    --> Zenith-List message posted by: Gig <wr.giacona@cox-internet.com> You and I seem to be at almost the same point in the building process. I built the Alerons this weekend. I was going by the constuction manual that I received at purchase (9/02) I did the cuts by the book and when the time came to put the tip on the bottom was not lining up. I had done enough that if it was bad wrong I was going to have to replace it any way so I went ahead a trimed the bottom skin to fit and finished the aleron and got within 0.2 degrees of the proper twist. I had the same outcome when I did the other one. So, before went and checked and there are indeed changes to the manual. In the earlier manual you do all the marking BEFORE you put in the shim in the new manual you do it after. At this point I'm left with the question is it more important for them to be the same or for them to be exactly as described. A called Zenith and the answer was make them the same. So I finished the other aileron as I did the first and they look fine. At least they do before I mount them on the wing. Looking at it I don't think you are going to be able to tell the difference. Lesson Learned 1. Before moving on see if there is a new manual section. 2. We aren't building the Space Shuttle. --> Zenith-List message posted by: "Michael Stempf" <mstempf@earthlink.net> Hey everyone, Have a question for anyone who has already gone through the aileron process, I am installing the end tip onto the ailerons - but they are not going on as flush as I thought they should be. I read the "tip" in the installation notes to put the top part of the rib over the 20 mm over hang of the aileron - but it still does not sit on there right.

    --> Zenith-List message posted by: Schallgren@aol.com List: Frank says: "One thing, do not fit the cowl under the fuse skin as it is almost impossible to remove it with the prop fitted." I have to disagree with that. We have our cowling under the fuselage skin and have removed it hundreds of times without problem. It goes back on without a hitch and I believe it is structurally stronger than with the cowl over the fuselage skin. Just my humble and strongly held opinion. Stan 601HDS/Jabiru 3300/Sensenich prop

Don't know how humble this can be but I disagree strongly with putting it inside. With my Jab installation and only about 3/16 of an inch between the spinner backing plate and the cowl, getting it to fit inside would only work if I were to remove the spinner and prop each time. What it boils down to is - How close to the prop and the spinner backing plate do you want your cowl? If a gap of an inch or more suits you then it may work on the inside. If you want a close fit for aerodynamic and aesthetic reasons, then fit it outside. Spinner diameter also figures in. The side and top skins in this area get their strength from their proximity to the firewall. By placing the cowl over the skins you minimize the chance that pressure on the sides or top of the cowl might crack or break area where you've attached your dzus, camlock, or other fasteners. With a cowling inside you scratch the paint on the cowl each time you slide it into place. Each builder comes up with a different vision of this area so go with what allows easy removal - whichever that may be. Regards Jeff also with HDS/3300 combo and soon to try a GT prop

    Subject: Re: Zenith List: Fiberglass Cowling
    --> Zenith-List message posted by: Michel Therrien <mtherr@yahoo.com> I believe that Frank raised a very good point that I was about to oversee. Thanks Frank. Perhaps with the stock ZAC cowling and a small spinner it is not a problem. But I have a 10" spinner attached to a HP hub (SAE 1 bolt pattern). That will be a custom cowling with a cowling "plate" about 1/4" behind the hub. So, in this situation, I now think that it would be impossible to remove at least the bottom portion of the cowling.

    Subject: sound damping
    --> Zenith-List message posted by: "Ron DeWees" <rdewees@mindspring.com> I found a product on the internet recently that I thought might be of interest to those finishing up the front end of their Zenith projects. I wanted something to dampen the vibration and engine noise and thought some sort of padding or mat would be the answer. I found some such products on the internet but also saw a reference to something called Quite Solutions that is a water-based coating that is painted, sprayed, or rolled onto a non-porus surface like aluminum. I put the first coat of three reccomended on the forward inside portion of the fusalage and firewall today and it seems like it will be a helpful product. When you tap on the outside of painted skins there is a dull "tunk" sort sound rather than loud rattle sound of unpainted surfaces. I still have 2 more coats to apply and won't know the ultimate results for a few months when I start the Jab 3300. The coating comes in several sizes and is made specificly for firewall applications. It's rated up to 350 degrees minimum and good down to -70F. I will report back on it's effectiveness when I start the motor. Ron DeWees 601HDS/TD Jab 3300 in progress

    Subject: Re:Fiberglass Cowling
    --> Zenith-List message posted by: "Mark Townsend" <601xl@sympatico.ca> May I offer a suggestion to this thread. Under the end of the fuselage skin rivet a piece of .032 about 50mm wide with 20 mm under the fuselage skin as well as a standard "L" through the same rivet holes on the inside which leaves an attachment lip of 30 mm to flush mount the freshly made cowling. This will amazingly strengthen the fuselage skin at the end and with an almost flush mount cowling will look quite nice. Yes it is added weight but it allows for a cleaner air flow and no scratched paint upon inspection. Also I would caution anyone from using the spray foam for contouring. It can take up to a few weeks to fully cure if applied to thick. I will not be using this product.
