I did get a confirmation from a friend in Finland, Max Johansson, that according to the new drawings, the correct measurement is 20mm from leading edge. Do not know why it was changed, maybe something to do with the cowling?? I will drill the holes now without hesitation. Best wishes, Johann G.

(just kidding... my flapperon handle made it too!) I measured my hole and the front one is 15mm from the front edge as you describe.. was unaware of the new 20mm dimension.. but anyhow, cannot imagine what difference it would make, tho I am sure there was a reason. I can testify that at 15mm, the plane will fly for at least 2 hours, maybe longer if you keep the throttle springs at their factory specification.

" Hi Kevin, I've a lot of the same questions, I'm about a week ahead of you having formed several of the tail parts. I bought an old -about 2001- rudder kit from a fellow and didn't notice anything untoward about the aluminum. I've since bought a couple of sheets from Aircraft Spruce to get me started and I have put Cortec on all inside parts so far. On the rudder I diluted and brushed the inside. Took about a day to fully cure. After that, I couldn't get it off. I sprayed the formed parts I have made so far yesterday and that looks to be the easiest way to work with the stuff. I am concerned that it really won't help and I'm thinking about doing a trial with some salt water and aluminum. Has anyone done this? I haven't seen any corrosion from fingerprints, I'm farther south than you and humidity has been very high when its not raining! Are you sure you have 6061-T6 and not clad? Pure aluminum will corrode very quickly. John in Mississippi 75 degrees and 100% humidity today! ________________________________ Message 3 _____________________________________ Time: 08:13:20 AM PST US From: Mark Sherman Subject: Zenith-List: cortec --> Zenith-List message posted by: Mark Sherman John. Not sure where you got your information about pure aluminum corroding quickly? That's why they put it on the out side of 2024 aircraft aluminum so that it WON'T corrode. The higher the alloy content of aluminum the quicker it will corrode. That is why ZAC uses 6061-T6, it is less likely to corrode than 2024 or 7075 aluminum. And is cheaper. As far as preparing the aluminum for primer. You need to etch it with Alumaprep and then treat it with Alodine. This removes any corrosion and treats the material surface so no new corrosion won't start any time soon. You should prime within 24 hours of this process. This is the mil-spec way of of preparing aluminum. You can find this at Aircraft Spruce. (haz-mat charge applies) Some local automotive paint supply shops carry it also. To the other person who said something about a salt bath. Why would you start the corrosion process on new material? Keep you aluminum dry and clean!! Mark S.

My construction is taking place in a very high humidity location and I have peices of aluminum that have been sitting around since September of 2002 with no sign of corrosion. Add to that, that back in the days I was shooting pistols in competition my sweat could cause hard chromed handguns to rust if they weren't immediatly cleaned after a match. Again, there is not a sign of finger print corrosion on any of my parts. Keep in mind, I'm talking about aluminum that has no corrosion protection on it except where metal meets medal.

Turnbuckles or cable shackles are not provided with your control system. Today I started to run my rudder and elevator cables and spent three hours looking for the turnbuckles and cable shackles, thinking I had misplaced them. They show them in all the pictures and drawings and have them on their demonstrator at Mexico. Why shouldn't they have been provided? I finally looked at the inventory sheet, which I hadn't looked at for months and low and behold, they didn't ship them. You get little plates with nuts and bolts instead. On the last page of the control section they tell you turnbuckles are an option. Not for me, if you don't use turnbuckles, you have no adjustments. My only thought and reason for saying anything other than being hacked about wasting most of my day is that maybe someone else won't have to look as long as I did. Plus I really wanted them today and it just strikes me as Zenith not being up front, cheap and cutting corners. Before someone says, "You should have read the instructions first", all I can say is that I have run a lot cables and don't need instructions for running cables and I know what parts are normally used.

Would you mind posting the part numbers for the turn buckles when you get them I am guessing that they are going to be off the shelf Aircraft Spruce kind of hardware? Or any other helpfulls to the Inexperienced riggers out there. Using myself as the prime example.Rigged an outboard once... Joe Motis 601 XL Do not archive
