Hello Jimmy,

I don't use a catheter on long trips, just a plastic bottle or two.  It helps when the autopilot is working well and its not too turbulent, otherwise it can be a bit of a challenge.

Jimmy, not flying yet.  I had thought I would be ready for inspection before the new year, but life got busy.  I have an estimated 10hrs of work left and then going over it all with a microscope.  Right now it looks like I will have it ready just in time for our windy season...

Hi Jimmy, I would definitely like to see your 750 up close. I've actually never seen one in person. In 2006 I went to the factory and got a ride in a 701 and built the rudder but the plane was just too small. When the 750 was introduced I decided to get one someday and the rest is history.

Hello Jimmy,

I have about 1,550 hours on my Zodiac XL.  I took two Jabiru motors to get there.  Both failed with camshaft problems.  I looked into other engines but in the end decided to buy a CAMit "CORE".  You could think of this as a "long block". Brand new case, crank, cam, cylinders, heads, fuel pump, oil pump etc.  I just had to move over a few parts from my old motor to make a complete engine - not necessarily easy but for me, doable.  The CAMit CORE cost about $14,500 US dollars including airfreight and import fees.  Yes, you must "import" the motor yourself because there is no US dealer.

The differences I have noticed so far are: Heaver cylinders with more cooling fins.  Better aluminum alloy in the heads, better oil pressure regulator and sandwich adapter, better crankcase ventilation, bigger through-bolts and nuts. And the most important change: its a solid lifter motor.  The cam-followers are made by Honda and have a 1 inch diameter instead of the .8 inch diameter of the Chevy hydrolic cam-followers.

The base of the Chevy cam-followers are too small and bite into the cam lob which results in either cam or lifter failure sometime between 700 and 850 hours.  Pete at Jabiru USA will not admit that there is a cam problem, but Ian at the factory engine factory told me there is a problem.  I have two dead engines to prove it and Jabiru has moved on to roller followers as a way to correct the "non existent" problem. 

After several days work, I started the motor today and it runs fine. So will the CAMit engine run to 2,000 hours?  I guess I am going to find out.  I did not want to "spin the dial" with Jabiru one-more-time, especially because the cost would have been about $5,000 more.

So there it is, my opinion.

Hi Jim

I had a copper line on it originally and was advised by some guys who have been around airplanes longer than me that I should change it to Teflon  because of vibrations.

 WELL BAD ADVICE  so im now rebuilding the motor with an electric gage

Hi jimmy

you know I think mine was black black green

ill have to go look

i only have 25 hours on it  but its at least a year and a half old

HI Jimmy,

I do have high oil temps.  218 in cruise 2400-2500 with ambient temp of 72.  I copied the Cessna 150 baffling with the scope under the crankcase and front of engine. On last flight I directed the 2' cabin heat scat at the oil tank with no effect.  Cylinder heads good highest I've seen is 390.

No noticeable oil burn in 0.9 hours on last flight so seems to be nearly broken in.

Jimmy,
