Breaking News from Super Petrel USA!

Ormand Beach, FL

Thursday, March 14th, 2024, the first two Super Petrel XP aircraft in the U.S. receive Airworthiness Certification from the FAA. The Airworthiness Certificates for these brand-new Light Sport Aircraft (LSA) marks a major milestone for the teams at Scoda Aeronautica in Brazil and Super Petrel USA in Ormond Beach.

This completes the long journey of these aircraft that arrived at the Super Petrel USA Ormond Beach facility on Thursday March 7th, 2024. They arrived in a single shipping container with two complete aircraft inside. Once safely unloaded, the ready to re-assemble aircraft were placed in the hangar where final assembly was completed.

The teams have worked tirelessly since 2017 to perfect the new XP design and have delivered these production aircraft that are now ready to fly !

With the Rotax 915iS fuel injected turbo-charged engine producing 141 hp combined with the new composite 5 blade e-prop propeller system, the performance and design of the all-new LSA from Super Petrel is simply extraordinary.

A few years ago, Rotax started something new – they did their first fly-in!  Rotax powered aircraft from all around the world were invited to come to their home base in Austria for a day of events and camaraderie.  It was a huge success.  One of the majour requests from that event was “why not in my country”.  This challenge was taken up but their marketing and the ROTAX® WORLD TOUR was created.

This November, the 25th to be precise, the folks from Cruzerio Do Sul (the Rotax iSC for Brazil) are inviting YOU to be a part of the second stop of 2024!

Midwest LSA Expo – Day Two Review

Mt. Vernon, IL

The second day of the show was very busy, a little windy and the sun came out…  So just perfect day!  Friday seems to have the most visitors and the therefore the amount of test flights.
Here are a few photos and thoughts from the day…

Yesterday we got a sneak peak at the 600 getting ready for a test flight, here is it’s brother the SkyLeader 400.  I know we must have said this a hundred times – but where else can a person go to test fly so many models and brands.  Midwest LSA Expo is the best place.
This lovely Gyro Plane was sitting just to the left of the main entrance.  It is the Kallithea (in Greek, it means the best view).  To find out more about this beautiful aircraft, you can reach out to the official distributors in the US, LA GyroPlane.
Hiding away at the far enf of the expo was the AeroTrek A240.  I am sure it was there to get easy access to the flightline!  For more info reach out to  Powered by the Rotax® 912 ULS.
What else can be said about the Rans S21 Outbound?  It had the most test flights on the first day and is powered by the amazing Rotax® 915iS Turbo! Here is their website. We were lucky to get a quick interview with Mark “The Pilot” …
We could not walk past this very bold Magni M24 Orion without taking a photo.  Last year Greg gave us a very detailed and informative video session on the brand and gyro planes in general.  He truly is the master.  Here is that video…
There is nothing like a Dan Johnson presentation.  Add the word MOSAIC to it and you have a very full room.  MOSAIC is really important to pilots and OEM.  Please (we can’t stress this enough) visit Dan’s very detailed page and get involved!

Midwest LSA Expo – Day One Review

Mt. Vernon, IL

I am sure someone out there is winding the clock a little faster, because time seems to be flying by.
Here we are at the end of the first day of this year’s Midwest LSA Expo and what a day it was.  Good friends, nice music and amazing Rotax® powered aircraft.

Here are a few photos and thoughts…

It was good to see Mike and the crew from Certus Aviation. They had their beautiful Rotax 912ULS powered SportCruiser. Certus is based out of Burlington, WI. They are a current Rotax Repair Centre, so reach out to them if you need a hand. (Stay tuned for a video)  
Just in front of the main entrance, we found this American Ranger from Silverlight Aviation. Also powered by the iconic Rotax 912 ULS.  
Just about to go for a test flight was this very sleek SkyLeader 600.  It is an all metal aircraft and the boast that they have the largest cockpit in the LSA Market.  They offer this model with a wide range of Rotax® power.  
Bearing in mind that the purpose of this show is to give new buyers a chance to fly and in some cases go home with a new aircraft, the folks at Leading Edge Airfoils the Rotax iService and Training Centre for the region felt it important enough to have their Director of Operations (Yeah, he is a pretty amazing tech guy too!) to be on hand for all those Rotax engine questions. Be sure to stop and say hi!  


It was not just about the aircraft though, the presenters for the day offered a lot of information and guidance.

First out of the gate was Paul Mather he is a DAR and owner of M-Squared Aircraft.  He went into great detail on how to get your aircraft registered and certified.  Providing some good tips and resources to navigate your way through some of the more intricate steps needed to accomplish the task of being legal.

Now definitely the most entertaining and passionate presentation of the day went to Steven Bateman.  He is the director of the AOPA Flying Clubs Initiative and amongst many other things a CFI as well.  Their main goal is to get people flying, and keep them active (and get you back flying if you have taken a break from your dreams for a bit!) Please if you were not able to attend this presentation, reach out to Steven.  They do a fantastic job.

As per usual at the end of the first day, there is a free diner (great food and drinks), prize giveaways and a 50/50 draw.  Here Brett Lawton (LEAF Director) receives an award from Chris Collins (Mount Vernon Airport Manager and Expo host) for LEAF’s 15 year commitment to the Midwest LSA Expo!

A special thanks to Chris and his amazing team of volunteers. The expo you guys put on is amazing.

2023 Midwest LSA Expo

Mt. Vernon, Illinois

I can’t believe another year has gone by so quickly.  It seems like yesterday we got the opportunity to visit one of the best kept secrets, but arguably one the most important aviation events for actual aircraft buyers. If you are seriously in the market to buy a light sport aircraft and you want to test fly your dream ride, this is the place you want to be.

For the past 15 years, the folks at Mt. Vernon Outland Airport have done an amazing of hosting the Midwest LSA Expo. The expo takes place over 3 days from September 7th thru 9th, and is unlike most other airshows/fly-ins. There are no huge crowds and no long line ups to speak to the aircraft distributors.

Top that all off with some very informative presentations by the likes of Dan Johnson, Paul Mather, AOPA and FAAST.  There will be something for everyone.
Click here for a list of presentations.

We can’t wait to catch up with some old friends.  See you there!

Oshkosh, WI.

My eyes were opened at this year’s Airventure.  For years and years I have been listening to aircraft builders telling me that it took between 2 – 5 years to complete their builds. Yes, there have been a few EAA One Week Wonder events, but in my mind at least that did not count.  Usually, every One Week Wonder project, has the best of the best builders on those projects, not to mention the huge amount of volunteers that assist as well.

Then I stumbled upon Kieth Furst in the ultralight section.  His was a truly self built project.  Yes he did have a builder assist support from the folks at Cierva Aero, but it this man works a full time job and he was flying in under a year!  That is what got my attention.  Not only was it an Autogyro MTO Classic, but it was equipped with a Rotax 912iS injected engine as well.  

As this aircraft normally comes with a Rotax carburetted engine, Kieth had to fabricate all the additional mounting and put in the extra wiring.  He truly made a thing of beauty.  Here is his story …


KITFOX RELEASES AN AMAZING VIDEO…. (I can’t wait for Oshkosh!)

Can you guess which of these lovely aircraft will be in the Rotax Booth (265)?
