Specifically, for the 601 XL with Rotax 912S?

It's great. Three ring binder with every page outlined you will ever need from Emerg proceedures, performance, Wt and Bal, Maint log, Flight test log etc etc. All you need to do is fill in the blanks. It has your emerg checklist already done, you just have to put in your airspeeds and info pertaining to your aircraft. It also has your normal proceedures check list all done. This is well worth the bucks.

I was supposed to go on Tuesday for the teardown of my Stratus, but I got a call at the last minute saying the NTSB had not released the engine. I just found out that they have scheduled the teardown for next Wednesday morning. I'll let you all know what they find afterward. ________________________________ Message 7 _____________________________________ Time: 07:01:29 PM PST US From: "Carl Bertrand" Subject: Re: Zenith-List: 912S Hard Starting --> Zenith-List message posted by: "Carl Bertrand" Hi Phil I'm not sure where you got the minimum RPM for a starting spark but I recall reading in the installation or maintenance manuals for the 912 that you need 700- 900 RPM. From experience the engine will not start if it does not turn at that rate. I don't have my manual with me but I'm pretty certain that 200- 300 RPM is insufficient. Hope this helps.

Today I have tried to find one and haven't been able. It is supposed to light and indicate charging. For 200 hours I just used a 50 ohm 10 watt resistor to protect the voltage regulator. It needs a small load all the time. That works but I would like to try the suggestion if I can find the bulb. Does any one know of a source? By the way someone asked about a source for the 23,000 micro Farad capacitor rated at 25 volts in their circuit. I found that Radio Shack has a 25,000 micro Farad rated at 50 volts. It is physically large, but it works fine.

But since the load is the important part you could always use a smaller bulb or LED wired along with the existing resistor (I would try and give you a circuit diagram, but since I'm not an expert I wouldn't want to give you a wrong one). When I asked a similar question on the aeroelectric list, Bob (the list's expert) suggested that I replace the bulb with a resistor which I'm sure is more reliable that a light bulb, since you won't have a load if the bulb is burnt out. If you go the combo method, then you'll still have the necessary load even during a bulb failure and an indicator light.

Both tools actually helped as I used a speed square and the jigsaw to make my primary cut and the sawzall to trim off a 1" on the strip. The jigsaw was easier to use for the long cut since it could ride on the edge of the speed square. I also used blades meant to cut metal with both tools which I'm sure helped. Actually was surprisingly easier than I initially thought. Only difference is that I'm not used to sparks when I cut and sand things. Probably need some way of cooling the blade and/or material during the cut, but the total amount of heat is far less than a fiction wheel cut. Only downside is that I'm probably going to go through my jigsaw and sawzall blades rather quickly, but I've only got a few pieces to cut so it's not like I need to keep my per piece cost down :) Thanks again for your help.

Here is what I discovered: After reading all the info on moving radiators further back where there is "undisturbed air," I moved my radiator back about three feet and ran hoses along the bottom of the fuselage to connect to the firewall. That is when all my problems began. Last summer, I started having all kinds of problems and eventually resulted in a BAD overheating event and "unscheduled" landing 50 miles away. I tried putting a scoop on the front of the radiator before this event and it still didn't work. After a rebuild and some engine trial runs, it appeared that the engine was running rich (a lot of carbon deposits on the plugs) so I leaned the main jet on the Bing out one notch. When I took off, I had a lot of power but the temps rose alarmingly on a brief climb out. Sooo.... I moved the radiator back to the edge of the firewall as per original instructions, made the mixture rich a notch on the main jet, and wrapped the exhaust with thermal wrap. When I took off this time, the water temp rose to about 210 and stayed there. Man, what a relief! My advice to my fellow "airsoobers": Leave the radiator up front behind the prop (even though this makes no sense to me), make the mixture rich enough (check by looking at the spark plugs), and wrap exhaust with thermal wrap (as per Jim Weston's email). I'm looking forward to a long summer of "frequent flier" miles!

In my opinion is better to use 0.5mm instead. The second all. alloy you can use is 2024-T3, but it is a little bit hardly to bent and is more expensive. I know there in Germany they have their specification of all. alloy, but for sure they are using international type as well.
