Hi Steve - Yes, Brad Demeo was the builder. I bought it from Glenn Bashforth in San Rafael. Very nice to learn that you were the original test pilot.

Hello,

My name is Mr. Michael Mccarthy, I have contacted you before without any response from you. Please replied if you receive this message. I have something very important to discuss with you, I have a vital information to give you. Could you please get back to me on (mmichaelmccarthy4@gmail.com ) for full details.

Michael Mccarthy.

 Hi Steve: 

 I read your blog entries about your original Jabiru 3300 engine, and the rebuild process, with great interest.  I then noticed that it appears you swapped out that engine and put in a newer CAMIT built version of the Jabiru 3300.  If so, I was curious if you’d be willing to share  what ultimately caused that change and how the newer CAMIT Jab3300 has  been performing for you?   I know that CAMIT is now defunct, regrettably; however, If you were building another aircraft similar to your 601, would you buy another current generation 4 Jabiru 3300 for it? 

At present, my top three engine choices for my 750 Cruzer are (in order):

(1) Jabiru 3300 (120 hp)

(2) AeroMomentum AM15 (137 hp version)

(3) UL Power 350i (118 hp)

I love the idea of the simplicity of the Jabiru 3300 engine, especially its independence from requiring a battery/power source for its ignition system and it’s engine driven mechanical fuel pump,    But, as  I also live in the Midwest, having a liquid cooled engine that’s an auto conversion is appealing, because it would provide effective heat for me in the cockpit, and it would be more tolerant of being started after sitting in the cold hanger overnight... plus it is content to run on 91 octane auto fuel. 

Sure appreciate any comments or insight you care to offer. Thank you very much! 

Kevin

Thanks Steve for the response re the spring gear.  If you happen to know the owner, would there be a way I could connect with them?

Hi there Steve,

We do seem to be like minded pilots. Every time I jump in my plane I make sure I go somewhere different. Long way to catch up on you tho...I also don't use a camera very often.

Australia is a great place to fly around. Huge country, great people. No where near as many airports as usa so planning requires a lot more care. Best time of year is usually June to August or so to fly around. Bit cooler and less turbulent.

You won't be able to hire a 601, but a similar factory built plane.....Technam or Sportstar etc....But yes, great place, you will be very welcome down under mate...

A follow-up on the plugs, Steve. The "factory" gaps seemed to be about .030, so I left them "as-is" and installed them. They definitely helped my radio reception rf noise ... sort of! Before, I had an "ignition" noise accompanying weak receptions that definitely varied with rpm. It was equal on both mags. After installing the NGK DR9EIX plugs, the right mag was completely quiet, but the left sounded about the same! Looking closely at the mags, the right's lead says "7mm high temperature suppressive", the left says "Electra Cable ECA 7". Looks like the cables are from two different vendors - wonder if that left on is not suppressed? I put 4 ferrite beads on it and it is quieter but not completely quiet like the right. Now I'm wondering if it is possible to change out that mag lead to a quality rf suppression cable?

And so it goes ...!

Thanks for the info on the Iridium plugs. I'll see what the "factory" gaps are when I get them and go from there.

By the way, how did the "reverse flow" sump cooler work out on your plane? If I understand correctly, you made an opening above your oil cooler and let the high pressure air reverse direction and flow up the sump fins towards the prop hub. I've got marginal oil temps at high rpms in my 750/3300 setup, despite a 10-row cooler. However, the engine's only got 23 hrs and still on the break-in 50w oil. I'll go to the 15-50 at 25 hrs, if things don't improve after that, I'm considering some sort of additional cooling and wondered how your idea panned out?

Steve, I think you made the right choice with the Sonex plenums. I've never had confidence in the Jabiru version, they work in the XL, but there are better solutions. My setup is a variation of the Jabiru and Sonex plenums and I will be making some modifications once I get the airplane to Bend. Hasta la vista!
