There was no room on the top. It did not appear there was a choice. I also added a lever arm to increase the throttle knob movement and allow for duel throttles. I am still working on making the mixture more even but I do have pictures of the present installation and will fetch them next time I am at the hanger within the next couple of days. -------- Mark Hubelbank N708HU CH601XL Jabiru 3300 Rotec TBI 40 carb Sensenich ground adj prop. 28 hr TAF Read this topic online here: http://forums.matronics.com/viewtopic.php?p=268513#268513 ________________________________ Message 2 _____________________________________ Time: 06:45:15 PM PST US From: "Mark Stauffer" Subject: Zenith601-List: Prop selection for Jabiru 3300 Rich, Somehow I missed your voice mail, it never showed up as a call - I got it several days later. Hopefully Dana was able to answer your questions. To answer your question here - I have a Sensenich wood W64KZ51. This was the recommended prop when I first purchased my firewall forward over four years ago. They've now switched to a W64ZK49. My first flight I saw 2700 rpm on takeoff and climb out at 90mph. Today I was seeing about 2790-2800 at the same climb out speed which is about right. Today was a cooler day in TN - about 60 degrees this evening. Tonight I was able to get 3060 at WOT. That may be a bit low. I'm still working out some jetting issues on the Bing, I'm running fairly rich in both WOT and cruise. I recorded an hour flight tonight in the GRT EFIS but shut the power off before I copied over to the memory stick. DOH!! Also, I have an earlier solid lifter engine - SN 845. At 3060 I was indicating 140-143 mph. I say this with the caveat that I'm still calibrating my ASI. I think it reads a bit high. Hopefully this nice weather will hold out and I can fly again tomorrow evening - and record the flight! Give me a call when you get a chance. Mark 601XL Jabiru 3300 6.3 hours! Hey folks! After a long wait, i have a Jabiru 3300. Yeah!! Now, I need to order my firewall forward kit and prop. There are 3 options. 1) one for short field take off 2) one for traveling - Higher cruse speeds 3) something in the middle. For those with the same engine, what did you choose an why?

My tests in knots were 107 KIAS=98 CAS 95 KIAS=88 KCAS 85KIAS KCAS 75KIAS = 73 KCAS 65 KIAS = 65 KCAS. By placing a small O-ring on the static port slightly behind the static port holes, I was able to get the IAS to equal the CAS in the 100 knot range but made the IAS about 10 knots less the CAS in the 40 knot range. It took several flight adjusting the position of the O ring to make this happen.

This shows a lever to increase the throttle throw and allow a duel throttle arrangement. At this time I have tested it with the ring shown in picture 668 between the carb and the engine. This makes all but cylinder 6 behave well. That one has too high a EGT during WOT. I will try the ring in 669 next. -------- Mark Hubelbank N708HU CH601XL Jabiru 3300 Rotec TBI 40 carb Sensenich ground adj prop. 28 hr TAF Read this topic online here: http://forums.matronics.com/viewtopic.php?p=268634#268634 ________________________________ Message 5 _____________________________________ Time: 08:18:37 PM PST US Subject: Zenith601-List: Re: CH601XL and Jabiru 3300 Performance From: "Ron Lendon" You guys with the TBI might want to read about the Tornado Fuel Saver.
