Greetings,

While considering engines for the latest Slingshot project, I ran across the Jabiru 2200 engines. I know Thom had one on a Slingshot, and he seemed happy with the performance. I've heard of a few on Mk-3s as well. Is anyone still flying with a Jabiru? Has anyone flown with the Jabiru 2200 and some other engine on the same plane for comparison? I'd love to see some additional installation pictures, particularly how the exhaust was routed.

FWIW, I'm currently looking at the HKS, Jabiru 2200, and 912. All of these have some pros and cons.

Thanks,
Rusty

the HKS is only about as powerful as the rotax 503 the jabiru would be a nice fit for your kolb

The Jabiru 2200 checks all the boxes for me, but I haven't seen many for sale used, and new isn't an option for any of these engines. The only real installation issue is that the wings won't fold with the standard pusher exhaust config, but I have to believe that can be fixed. Otherwise it's a clean installation, with reportedly good performance despite being direct drive. The other bonus is that the US Jabiru dealer is only about 3 hrs west of me if needed.

The HKS appeal is that it's the lightest, most compact 4-stroke option, as well as being the quietest with the 3.47 gears, and probably the most fuel efficient. My old 503 SS performance wasn't all that bad, but I was young, and feeling the need for speed. Now that I'm getting old, and have proven repeatedly that I won't travel in the plane, I could probably be happier with the lower performance.

Of course the 912 is hands down the most popular option, but they're pricey, heavy, noisy, and require water and oil coolers. The years have taught me to go with the flow a bit more than I used to, but I hate to be too conventional Smile

For me the problem with the jabiru is the direct drive.    You'll need a shorter prop, which is ok if your plane was designed to fly faster.   Say 125 mph or so.  The faster turning shorter prop becomes  more efficient at higher speeds.    The kolbs need a longer slower turning prop too get the most out of the engine horse power.

Might do some checking about the cooling of the Jab...I have chatted with tractor and pusher builders and some have mentioned cooling difficulties...Herb

Boyd, For what it's worth I've been working on a friend's Zenith 701 with a 2200A Jabby and a two blade Sensenich prop. I set the prop for 3120 RPM static at which it pulls 310 lb. as measured with a digital force gauge. My concern on a Kolb would be the need for a light weight prop. The Sensenich is built similar to the Power Fin, i.e. light and hollow and won't tolerate FOD like a Warp Drive will.

There's precious little data available for Jabiru equipped Kolbs, but I've been exchanging emails with Thom, who owned a Jabiru 2200 Slingshot. He was definitely a fan, and it sounds like it had plenty of performance with the 64" prop he was running. Cooling shrouds are a must, but I wouldn't expect any air cooled engine to have optimum cooling without them.

I've actually been trying to buy an HKS that was up for sale, at a price that would make it worth trying. It doesn't look like that's going to work out though, which may be for the best.

That's good to hear. I'd love to see any installation pictures you have.

Thanks,

Thanks for the comments, but fate was working overtime today. I ended up talking with a local pilot, and he mentioned having a 912UL he was planning to sell. Turns out it's a great engine, at a great price, and less than an hour from my house. In a few days, I should be the lucky owner of a 912. Now I need to work on selling my RV-3B so I don't have to sell a kidney or two to pay for this Smile

Cheers,
Rusty
