I finally reached the point where I have the engine mounted in my Zenith CH-801. The Instrument Panel with Engine instrumentation is connected. For the last three weeks I have attempted to start the engine. It was apparent the injectors and the plugs were not firing. I was assured by your Sales Manager the engine had been run before it left your factory. In frustration, we finally removed the ECU to examine it. By this time we had done a complete continuity check on all of the circuits checking for good connections and no shorts or grounds. I was confident all of the connections were good and this proved to be the case. We checked all of the voltages and they were acceptable. Finally we opened the ECU to look for any evidence of damage. We found none, but we did discover the manufacturer of the ECU to be DTA and the model was the PR8 w/Ver 3.0 of the software. We accessed their site and downloaded their software and manual. I have been saying we and the we is myself and my son Michael. He is well versed in software as am I. We have worked with Leading Edge ECUs and Electromotive TEK II. My son scanned the forum and found a person in Norway who had had similar troubles as we did with an engine. DTA pointed out that if there is not a clear Crank Position signal, the ECU will not fire the injectors or the plugs. We were suspicious. Now the Crank signal is a magnetic reluctance pick up as you well know. This is a high impedance, low voltage signal and in such cases it is prudent to use shielded twisted pair with a drain. You had. Now one other thing that is sound engineering (I am an Electrical Engineer by trade) is that you don't ground by ends of the drain. This causes circulating currents and will induce no end of noise. I found you had grounded both ends of the shield on the crank sensor signal line. We clipped the drain at the sensor end and lo and behold the engine started. DTA also states that one should not put the coils in parallel for wasted spark applications as this can blow out the coil drivers. Their installation instructions are to put the two coils in series. To conclude, I am significantly disappointed and upset at your design and manufacturing of this engine. You obviously don't understand the proper design for signal lines and don't seem to follow the instructions from the DTA ECU designers. It would severely disastrous for a coil driver to blow at 12000 feet!. It is also apparent the engine had not been run prior to shipment because you wouldn't have been able to start the engine any more than I could. I think you need to notify all of your customers of these issues and immediately issue corrective instructions.

This was after several telcons with tech at Dynon regarding OAT and interference from other electrical ( ie., Antennas, motors, strobes, etc.). I elected to plug OAT into remote compass, to save more wiring going forward. The install was done before closing the rear fus skins, so it was much easier, but you could work through the access panel if elected. Leveling was done to the longerons and across so that D100, when installed could be done to longerons and panel; however, the install of remote compass with brass screws was made to be slightly adjustable if necessary, with washers. A digital level works great for this operation. Will see if I can attach some pics to this note for clarification.

A couple years down the road, when my plane is done, I plan to polish it, possibly with the Nuvite stuff. I figure although it may take more time, it will be lighter and cheaper than painting. I do plan on having painted highlights, though. I also think that if for some reason I decide to paint all of the aluminum, I could do this after the polish job. But recently, I had been told that some folks have had problems doing just this. Something about not having the paint adhere will around the rivets, where residual polishing material hadn't come off. There may have been a bleeding effect, I'm not sure. Anybody have any experience or suggestion about this?

Anybody have any experience or suggestion about this? Hi, Dan et al, I am in the midst of painting The Bird as we type. I found a small round gizmo that chucks up in a drill that will "score" around the rivet heads about the same as Scotch Brite does on the flat stuff. I got it at O'Reilly's, about twenty five bucks. I later found that one could get a brass wire spinner at the local weld shop for about six bucks. It would do the same job. I had to eliminate some orange peel by lightly polishing and I washed the parts with Dawn dish soap prior to painting. It seemed to remove any and all the residue polish. Time will tell if I got it all, but it seems good now. Here's some free advice (as most is). Anytime you are "scuffing" the existing paint, or the aluminum, prior to painting, ALWAYS use a new piece of Scotch Brite pad. I made the mistake of using a used piece on white paint (small areas) and some of the imbedded aluminum from previous scuffing became imbedded in the white paint. It made the areas look dirty. To re-do these areas would take weeks to re-do and about another $300 in paint to correct and then there would be absolutely on guarantee of a good paint job, so I chose to live with the dirty look as a reminder to NOT SKIMP! Other than that, the paint job is very satisfactory for this rookie in a small workshop. Enjoy!! Hope this helps.

My question is about problems associated with painting after polishing. For example, I may want to paint it a year or so after the original polish job. I have heard some people have had problems with the polish effecting the paint.

I plan on polishing most or the skin and painting highlights. And I will be doing the painting. So after the polish how do you get the paint to stick? I assume you polish everything, but as little as possible on the part your going to paint...but what about the line es between and the parts you didn't mean to polish? Or like stated painting after polish? Thanks Kevin -------- Mark Twain: Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do.
