Yeah, I got the 4-blade out of the factory, so I just need the POH and the VGs. My ICON comes off Demo lease next month and will have the mod stuff done during turnover maintenance. Work will be done here in Denton TX (KDTO) at US Sport Planes (ussportplanes.com , 940-597-6860). The mechanic is now an ICON Certified repair place, so I will have maintenance on the field. Anybody nearby who doesn't want to go to Tampa can swing up here to get work done.

So for those of us who didn't get the 4-blade on our original aircraft: Icon wants $6500 for the prop BUT AN EXTRA $5500 ON TOP OF THAT ($12000 TOTAL) IF YOU WANT THE 60 LB GROSS WEIGHT INCREASE! That's crazy

I am happy to help refund all their development and testing hours to get the 60lbs added to my airworthiness certificate. If someone is 160lbs or less, maybe the extra gross weight is less important. At 200lbs, I will gladly pay for the engineering.

My plane partner and I just did the GW upgrade at the factory in Vacaville then flew back to Seattle. The reduction in cabin noise and vibration from the new prop made the trip much more enjoyable and we both felt far less tired. Going into that upgrade we were both ambivalent about whether it would be worth it. Now we're glad we did! I'll be planning longer cross countries now.

Hello Steve, Can u take a picture of the Stall Strip Vorticle Generators? I would love to see their design and position.

Took redelivery yesterday with 4 bladed prop and useful load increase. VERY noticeable increase in performance, true airspeed of 90 knots and decrease in volume in the cockpit.

Mine just arrived (in a box) yesterday. Unbelievable how lightweight the blades are - and the weight of the hub is even more amazing.
The FedEx guy delivered it to our open garage and placed in right behind the rear wheel of one of our vehicles. Luckily we saw it before jumping in the car and backing out. THAT would have been a bad day. -

Wow... Close call Michael! James, thanks for the great feedback. I am glad the new prop is getting so many positive reviews!

Is there printed details in the installation instructions, as to where exactly they need to be placed? Would like to see that page, if someone has it.

here is a link the VG'S ICON uses you can get 100 of them for $62 but knowing where they go on the wing is extremely important.

After looking at the photo I’m baffled at the location of those VG’s behind the stall strip it’s non-sensical. Knowing who they had left to do the flight test and the “experts” they had available to them I question everything about this choice. I was hired by, worked for, and sat next to Jon Karkow for 18 months until his untimely passing and we talked about spin resistance aero and flight testing a lot and just how hard it was to achieve. I’m confident he would shake his head in annoyance at the those 4 VG’s behind the stall strip.

Visually, I also wasn't thrilled about the additional VGs in that location at first. However, after extensive testing of a variety of different solutions (flap droop, VGs and other enhancing materials in various locations, etc.), this solution proved to be the best way to achieve our goal of increasing the gross weight without increasing stall speed. This was an important initiative for us, and I'm grateful to our Engineering and R&D teams for delivering. The flight testing to validate the solution and gather performance data was thorough and very time consuming and utilized a flight test plan previously developed by Jon Karkow and spin resistance test procedures that were authored by Bret himself.
And while MOSAIC might provide future opportunities to further enhance the useful load and eliminate the stall speed restriction almost completely for the A5, until then, ICON owners can enjoy an extra 60 lbs from this enhancement plus additional weight savings from the new lightweight propeller.
I'm proud of the team for achieving this objective despite the internal and external challenges that were facing the company at the time and I would politely push back on Bret's insinuation that the engineers and test pilots who worked on this project lacked "expertise." Having left the company more than three years ago, I don't believe he's qualified to make that assessment at this point.
