I'm not sure this would work with lexan but it's worth a query to Dupont. Or, if you have any trimmings left you could do your own test using metal or glass containers. You'd need a big dipping tank to do it, but a cheap inflatable or extruded plastic swimming pool would work fine (you'll need 2, one for dye, one for rinse). You could tint a portion of the canopy just by setting the level of the dye solution in the dipping tank. But... I sure like the idea of a hat!

Opinions are like, you know, and everyone has one but I must say as a professional engine builder that the whole problem here is that unprofessional people are the ones building the soobie. This is NOT an attack. I have seen quite an array of engines in my shop from different builders, and I must say that most of them are building engines to "get by" instead of addressing the issues of an aircraft engine. It seems to me that the more you spend on an engine the less you make and this looks like the angle taken or they simply can't do the work. I, as an engine builder for 20+ years, have found that this just doesn't work. If you sacrifice quality for price you will eat it. I'm not saying I have not made mistakes, we all have, but there is a difference in knowing and just not doing it. This is the reason for failure in the soobie NOT THE ENGINE. This is a good little engine and is more than capable of running in the rpm ranges of an aircraft engine with a redrive, if the engine is built right to start. If you plan on building your engine yourself, great, but be advised you can't just hone the engine, install bearings and rings, give it a valve job, larger cam and carb, and expect great things for it. You must build between the lines as well. Well I must go to work now, so thanks for your time, Ron ________________________________ Message 8 _____________________________________ Time: 05:58:36 AM PST US From: "Chris Boultinghouse" Subject: RE: Zenith-List: Tinting canopy? --> Zenith-List message posted by: "Chris Boultinghouse" Hi Frank, If you check at the local auto parts store you will probably find some stuff that will work. Instead of a tint film, it's a piece of sticky-back material with thousands of tiny holes in it. You can still see through it because of the holes, but it blocks the sun. More importantly, it will adhere to the inside of the bubble and still look nice from the outside. One of our local chapter members (Mark Frederick) used it on the inside of his Rocket canopy. You can kinda see it in the pictures here: http://www.airbum.com/pireps/PirepRocketII.html It's that dark stripe down the inside of the bubble. Sorry I don't have a brand name for you, but that should give you something to go by as you browse your local auto parts store.

I understand the issues around shock cooling, but I just can't get over the idea that all the water and all that plumbing is heavy. I also like the mechanical simplicity less pumps and water pipes and radiators. I'm not trying to ignite a debate, just stating a preference. In my book the Corvair is a every bit as reliable as the Jabiru 3300, based on William Wynne's experience, and less than half the cost. I also like the idea of being able to build it from plans.

My experience with the CAM100 has been similar. I didn't intend to learn so much about engines when I started this project. I wanted a 'plug and play' solution. If I had to do it over again I too would have sprung for a Jab 3300 or a Rotax or even a Lyc 235. For those who don't want to become engine experts, I recommend these engines that have 'certified cousins' and all the support that comes from that. If you install an auto conversion, you will by necessity become much more involved in your installation.

Chris Heintz, in one of the writeups on the ZAC website, talks about the risk if one side of the extension mechanism is jammed and the other side isn't, which would (I presume) create a very sudden and large rolling moment when one side extends. I suppose the response of a properly trained pilot would be to add power immediately and repeat the landing attempt below slat extension AOA. Have the Daedalus people thought of this? Do they have a recommendation? Or is the mechamnism set up so that this is a highly unlikely scenario?

Rebuilding details are documented for the engine guys, but for the rest of us, a scattered base of knowledge is available to improve our ability to fly the Subaru package. The best thing is putting enough instrumentation into the plane to know what is actually going on. Direct gages are good, but an electronic Engine Information System that tracks EGT, CHT, RPM, oil pressure and water temperature all on one screen at the same time with alarm settings for max and min is an inexpensive and indispensable tool for the experimental Subaru. Knowing what the data should read before you fly the engine is essential. You program the EIS to these limits and you get warning alerts up front quickly enough to make corrections before any damage can be done. You have to compile information to set your EIS and become familiar with jetting for a correct mixture, getting correct timing, having a dual source ignition, obtaining good cooling at the radiator and balancing carbs, all before the fact to keep your Subaru out of the weeds. It's a lot to learn, not having been an engine guy. I was confused in trying to read and understand CHT, EGT and Coolant temperatures and had managed to use the wrong thermocouples. A good operating picture wasn't there until consistant engine readings verified the information I'd read in Subaru specs, articles and helpful posts from this site. The installation of the package Sub is straight forward, but details for running are a worthwhile stretch for your mind if you like a challenge.

From: "Bima, Martin" --> Zenith-List message posted by: "Bima, Martin" Be careful with the assumption that if the manufacturer claims -6g's, then the ultimate is -9g's. It is usually the opposite in the kit plane world. The 701 (and maybe the Pegacopy) is rated at 6g's ultimate (that's 4g's design). What is the difference between ultimate and design?? - a safety factor of 1.5. At 6g's, the 701 is "designed" (emphasis on the quote marks) to fail, but don't go past 4g's for your own safety. Why did kit planes start to give their speed in mph instead of knots? To make them sound faster.

I spoke to Gilles Boulanger about this issue, and he said that during slow speed maneuvering the slats WILL extend with asymmetry, but the flaperon has full control authority and it is not a problem to control. The slat mechanism is built with a jig (supplied with the kit) so it is accurate. The slats are made to extend easily and at time unequally.

In addition you need to look at the engine mounts that come from Stratus. Unless he has changed things they are of mild steel rather than 4130 and there have been numerous reports of cracks found in the upper right bracket/mount as well as other brackets.

You may remember that I posted a question about my engine sputtering. Well, I found the problem and it was so simple that I can't believe that I did not think of it sooner. I had mounted the fuel boost pump on the firewall. THIS IS A BAD THING TO DO! The fuel boost pump should have been mounted inside the cabin area so as to keep it away from heat. The fuel was being heated and then turning to vapor which in turn caused the engine to sputter. So, plan ahead and make room for your fuel boost pump under the seat area or some other place inside the cabin area.

Find a working example of your desired conversion and copy that. Do not try to reinvent the wheel unless you are an expert in the field. I have no comment on the $7,000 off the shelf conversion that did not work. I have however seen some $2,000 conversions work great. If you want to do a auto conversion you need to plan to spend a lot more time. Most of all you need to do your homework. There are many examples of VW, Corvair, Subaru, Suzuki, Geo Metro, Chevy and Ford engines flying with great success. They all have one thing in common. The owner, builder was their own mechanic and they did their homework. They also where successful in keeping the damed thing cool. If you cant keep it cool it matters not what engine you have. By the way, those airplane engines fail as well. Just another mans opinion. Brett I normally dont post to this list, but I just returned from william wynne's "corvair college #8". I am very excited about this very affordable auto conversion, considering all I have to do is copy William's 601 installation, and total firewall fwd cost is something like $5000. I see all of these recent posts about the subaru installation and am wondering if any of you have considered the corvair. We had a great time at the college. There were more than 40 people there throughout the weekend, and I believe well over a dozen engines had some work done to them.

They are really very simple, lot of clearance in the slide. There is nothing to jam unless you get dirt dobbers in them, but that is what pre-flights are for. And, I did ask that question of Gillis of Dedaluis. He said they have never had that problem, none of the builders I talked to mentioned it either.
