Sun n Fun was Sun, Fun, and Wind, but mostly fun with a good turnout of existing HKS customers and prospects. Gerald J. Olenik, pres. Green Sky Adventures, Inc. was on hand at the APSU exhibit, just like Sebring. For this show, Jerry was given the opportunity to do the flying of the QuasarLite, which flew daily out of the UL strip. Mr Hasegawa, President and cofounder of HKS was on hand for one forum and a short media event. HKS engineer, Mr Taka and one former HKS engineer were also present, providing technical expertise on all facets of HKS engines. The HKS story is as impressive as the engines they produce.

We had a great time at Sebring! The APSU team was a pleasure to work with, and our combined efforts are sure to help more lucky pilots choose HKS for their aircraft engine requirements. Click Here for a few Sebring Pics

Coming up on Christmas season, here's one of our favorite items for nearly 20 years The Engine Information System from Grand Rapids Technologies. There are versions of the  EIS for almost any application with pricing from around $500. Basic engine parameters like RPM, CHT, EGT, COOLANT TEMP, OIL TEMP , OIL PRESSURE and so forth are just a few. The proven robust EIS should be on your required equipment list, whether Aircraft, Boat, or Hotrod.  Details at EIS

There's more info out on our HACman mixture control. It has now been on the Market for 4 years. We have posted some fuel flow data and other information. If you fly an HKS, Jabiru, or Rotax. You need HACman. Reduce your fuel flow, not your flying. See more info HERESept. 21, 2007

More HKS 4 stroke conversions are coming! As it works out, our new mount package for the Fisher FP 404 is
nearly 100 percent "Turnkey" Ditto, for the Fisher Super Koala! See more info HERE

April 27, 2007Green Sky now have Challenger and Kolb installations for the HKS 700e. Our first Kolb out in Hawaii is just about ready for first oil change. The second will be flying soon. Our new Top mount Challenger is just about ready to go. See Challenger info HERE (watch for new kolb material on our web site soon.)

Green Sky Adventures, Inc. has introduced a cross brand Trade In program accepting Rotax 2 stroke trades on the HKS-700e 60 hp 4-stroke. Click HERE for details

Oshkosh begins Monday July 24. Most orders during the week long event will be filled during the week of July 31. Gerald Olenik, president of Green Sky Adventures, Inc. will be flying the HKS powered Zippy Sport in from Florida. It most likely will be parked in UL parking near the red barn. Jerry will be working with HKS engines at he HPower exhibit in the UL area.

Kolb HKS update. We have been fortunate to begin communication with a Firestar owner on development of an HKS installation package for the Firestar and Firestar II.  We expect rapid progress on this following Oshkosh.

Quicksilver Sprint II. and HKS.   We're 99 percent with the Quicksilver Sprint II installation development. Thanks to the effort and cooperation of one dedicated owner, our goal of providing a "turn key" package is within sight. We currently have basic mounting, and accessory configuration locked in and readily available. We will get pictures and flight report up on our web site shortly after Oshkosh.

GT 400 HKS
This is as well proven as it is effective. Mounting packages are readily available.  Don't forget, we still take Rotax trades.

Rans S14 / 12 HKS update.  The Rans S14 and our "Low Rider" installation have proven to be better than expected. By keeping the engine as low as possible  and with Carburetors, Exhaust, and Oil Cooler ahead of the engine, CG works out great and drag is reduced.  The pilot of the first flying example with the mounting solution reports improved performance over the previous Rotax 582.  This concept has worked so well, it will be seriously considered for other upcoming popular top mount pusher conversions.

Zenith 701 / HKS. We currently have two owner installations in the works. One is a new scratch built example, the other is replacing a Rotax 582.  The first one should be flying in the next couple of weeks. To our knowledge, this will be the first HKS powered 701 in the US. Of course, we hope to follow up with these to make the HKS 700-E the logical power choice for this aircraft.

Kitfox / HKS
With over 150 hours on our converted Kitfox, and hours accumulating on other HKS Foxes. It's practically a given, the HKS-700e is the best game in town when powering the Kitfox.

April 3, 2006
Sun n Fun begins on Tuesday, April 4.  Most orders during the week long event will be filled during the week of April 10. Green Sky Adventures, Inc., president,  Gerald Olenik is scheduled for an HKS engine forum at 9 AM on Wednesday.

We'll update that log frequently. It's at CLICK

Comparing cost of operation. HKS vs. 2-stroke. In 500 hours the economic waste of 2 stroke operations exceeds the cost of a new HKS-700e 4 stroke.  It's like paying for an engine you never get. Check it out HERE

Reinstated!  We have cleared up a misunderstandings that led to our 2-day pause of Repair Station Status, by removing. Rotax advertising, name, logos, etc from our site.  This should not  deminish the usefulness of our site, If there is something you don't see, or additional information needed, please email, or call.

Dec 03, 2003
Our Rotax Repair Station status has been "revoked" with little explanation. Advertising outside an area, is not within the scope of the Repair station, and the World Wide Web, is obviously outside our area. Their also may be some issue that we offer, support, and promote, the HKS 700-E which is a highly competitive alternate to Rotax 2 stroke, but there was no mention of this.
