I have done some technical reading on this lately. With my lack of carburetor knowledge the conclusion I have drawn is that you are correct. A proper aero carb and mixture control seems to be better suited for motor operations at altitude. The air flow is important to temps/heat as it is to proper mixture in the cylinders before the moment of "fire". With some of the temps we've all seen, I wonder if we are just shy of pre-ignition. If we see swirls on the piston, or "clean" plugs, or cracked ceramics, then the engine is on the edge of overheat or meltdown due to pre-ignition (firing early which results in power loss in the piston stroke). Bad stuff. Excessive heat can cook oil, too.

My concept with the box is a 4"x4" (or bigger) chamber after the air filter box and connected directly to the Bing carb. It would have a side entry hole allowing a straight hose from the air filter box to the carb. This would replace the bent hose from air filter box to the carb.

Jake sent me the link to the TBI sight with the carb inlet illustrations. Does it make sense to eliminate the 90 degree hose from filter box to carb by using another box as in illustration 6-7 and a straight hose to it?

H i Stephen, Glad you liked the picture. I was taking a 701 to Billings for a friend after he sold it. I still have my 601. Bill

Steve, I was having a conversation with Jabiru Jim last week about the carb. Previous manuals were lacking just a bit, but I think these latest versions are a good resource, along with the Engine Tuning Manual.

Somewhere I read that the the diaphragm should be replaced every 100 hours and was wondering what your experience had been with the Bing?

Thanks for the link, Stephen.

Took a look at your blog posts about the tablet PC, data downlink etc. I worked with a programmer friend during my first (abortive) build attempt, and he talked up a similar system, including tiny webcams at various places in and on the plane. Nice to see such a thing is actually possible!

Like my PC... there's no good time to buy, you just have to do it!

But your layout embodies the vague plan I had for my own. Same with the sunshade (have you posted details of the installation somewhere?)

Thanks Steve. I'm glad I'm just starting my project. It's going to take awhile to talk my wife into $450 a gallon paint.

Thank you for sharing the details of your flight computer system. To say it's impressive would be a tremendous understatement. I'm particularly impressed with your real time flight data logging to a ground-based server. Very clever.

Steve, Great photos on your site!

I'm curious what kind of speed your getting and what kind of prop your swinging with that Jabiru??

Steve, I haven't played with this site, been busy building and wasn't familiar with the comment section. Mack is currently on an extended vacation with his wife. I believe you know that he was having tach problems and is waiting on a part from Jabiru, other than that he's ready to fly. I need to get the plane flying by the end of March to have any chance at making Cloverdale on May 9th. It's good to be an optimist :-)

Thanks Steve. Your photos are good too. In my case it is just being in the right place at the right time.

Cheers from Spain

Steve, great photos!!! I remember your XL as one of the nicest I have ever seen.

My project is still under construction, but should be ready for first flight in 2010.

Cheers from Switzerland,

Hi Stephen. Happy New Year.
Thanks for the kind words. Your plane is also very nice and all work looks very professional down to the finest detail. Sure would love to fly in your part of the woods someday. Great pictures.
Best regards from Iceland.

Stephen I read in a response you left another member that you have an airplane tracking system, what are you using and do you know of alternatives?

Thanks Steve. You are a great contributor to this new site.
Adding more stuff to my page.
Cheers, Bob

Eventually, once the finances allow. For now I'll be flying the Ercoupe.

Thanks! Unfortunately I had to sell the plane and it's at Hood river Oregon now.
