Thanks for the info! Yeah, not looking to try, just curious if attempted or not (having an emergency drogue chute like other aircraft have done in testing). The emergency chute is the way to go in that situation indeed.

As for development and testing, it’s very fascinating watching the videos of all you folks did! Such a unique product, Thank you!

Sure, The Proof of Concept aircraft (POC) first tests had a rocket fired spin recovery chute mounted to the tail, it was never used. Len Fox was the test pilot on a lot of that testing too as he is pretty much the go to guy for spin testing aircraft. He has done so much unique testing over his career he is held is super high regard amongst the test pilot community.

The initial strategy was to make the aircraft spin recoverable but Jon Karkow thought it could make it spin resistant. He was right, and It was a worthy endeavor.

I too am somewhat perplexed by the placement of the new VGs behind the stall strip. I spent waaaay too many hours as an undergrad doing wind tunnel tests back in the days when VGs and stall strips really weren't that common. I was always amazing how such a little thing as a VG could make such a big difference in the boundary layer separation characteristics. But those new angles, along with the stall strip in front, have me scratching my grey hairs! Anybody ever come across their diagram of placement?

I would appreciate seeing the template as well. If anyone that’s had them installed wouldn’t mind getting a copy from the installer. This should be documented here for a couple of reasons. 1. As a backup copy for anyone that’s had one or more come off. 2. We are fortunate to have some experts in this forum, that could chime in with their opinions on the placement as well. Especially during a time of uncertainty with the future of the A5.

I’m looking for some vortex generators to increase my useful load. Does anyone know where I can purchase some? Icon is saying the factory won’t sell them any right now because of the current restructuring.

You can buy the same VGs from Aircraft Spruce, I think, as Icon uses, but without the template for their placement you'd be only guessing on how to apply the to get the desired results.

This is the link to the specific VG’s. As Gabriel mentioned, knowing where to place them is the real challenge right now.

First if ICON didn’t supply you the Major Repair Alteration (MRA) document with the associated POH even if you knew where the VG’s went you wouldn’t be legally allowed to increase your gross weight. My understanding is the MRA is for both the 4 blades prop, VG’s and POH. It has to be that combo. although I disagree with the VG placement the only reason they put them on there is to lower the stall speeds with the added weight to stay under the 45 KCAS stall requirement to remain a LSA.

So if you are willing to just add the VG’s without the paperwork and roll the dice there for 60lb of useful load why wouldn’t you illegally fly you airplane over gross weight? I’m not advocating for that by the way, do it the right way and wait for the Chinese owners to get their shit together and get the right paperwork and parts.
