Ray, Did you want to put a link with this or do I have to get out my Oiuja Board?  

Okay the board says it's the Hexadyne. Must have been run out of Utah.

Sounds like the Aero-Twin engine. $6900 is the price for 50 HP non turbo engine. By the time you add for the re-drive, exhaust, oil tank, oil cooler, etc you are close to $10000.

The HKS 4 stroke engine looks like much better design, more refined, and advanced engine for basically the same price...   HKS has been around for a while now, and looks like a stable, growing company...



Without parts, your engine is a pile of metal, why would anyone risk an off brand engine, with less development and reliability, when a proven engine like the HKS is available at the same price ???

Hi All,



Is there anyone in our group that can stop by Henderson NV and take a look at this engine up close and get pictures to post here? It would be good if there was bit more info regarding this engine besides what the manufacturer's web page.



As far as engines go it would be nice to have some more four stroke alternatives out there. Yes HKS has been around for awhile but even they were new at one time. I imagine the same things being said about them regarding if they are going to be around or if they are just another flash in the pan.



If BRP /Rotax would get off their duff and offer the ETEC fuel injection system on their a/c engine line I think it would greatly improve its reliability. I just doubt that this will ever happen.

I never did hear what engine you were talking about. Do you have a web site, 

name or anything?

Too much plumbing would be necessary for the average guy.

This is not the Hexadyne P-60, but the Aero-twin.

  

 On paper, the P-60 looks good, but it is a radial mounted engine instead of  bed mounted.

  

 The Aero-twin looks REALLY good, but that $10k price  [w/ all the  necessary goodies] for an un-tried engine [at least on a Kolb] is a bit  much.

  

 If I's rich I'd get an HKS.  Looks like I'll just de-carb the old  trusty 503................................

Not true, it is not at all the same situation.  When the HKS came out, there was no good, reliable, light aircraft designed 4 stroke 2 cylinder engine available on the market that was suitable for very light aircraft, at that time trying something new made sense.  Also the HKS design is very good for reliability and aircraft use, NOT so with the Aero Twin.   



Now, the HKS is available, proven reliable, and in use on many types of aircraft for the same price as the new engine...  So why be the test case with an inferior engine, when the reliable, proven HKS is available at the same price  ?   If you took the time to look at the manufacturers website, there are plenty of pictures of the engine from many angles.   Given what I see of the pictures, the design of the Aero Twin is inferior to the HKS, I would not want one, to many mistakes and compromises in their basic design to make it a good airplane motor.

It also appears as if the Oleniks are working on a mount for it for the Kolb, as there's a slingshot with an HKS on it for sale by them on barnstormers.



The Oleniks are smart guys and do good work, so I'm sure they're going to come up with a reliable mount.



The HKS looks like the best contender for that gap between the 503 and the 912 which is currently occupied by the 582 and some other 2-strokes. The clever thing they did with the HKS is made the operating RPM's and gearbox ratios very similar to the 582 and its gearboxes. So you're not in totally unknown territory when it comes to prop selection and operating rpm etc.....



I still think it's a bit heavy for something like the FS II, though it does seem to work. It looks tailor-made for something like the Slingshot tho....
