To your point, I admit the USN was self-insuring.

It should hopefully make a natural pitch down with rudder deflection.
Other airplanes trying the rounded low wing taildraggers with small tail have had a history of spin issues. Ventral and dorsal fins creep into the design or slots like the Swift. The large forward wheel spats size close to the CG vs vertical fin area and further back. There's a spin video on their videos page. A little further up there's also a short "wing unfold" clip. https://spiriteng.com/videos/

The F11F and then the F8U. Too cool.

And for Sonex that is fine, it is one plane among many models that they sell. That would be a tough situation though, if this was the only horse in your stable.
This is MUCH more aesthetically pleasing than a Onex, a bit reminiscent of a Ryan PT-22. Apples to apples, I’d prefer this new design over a Onex.

Apples to apples, I’d prefer this new design over a Onex. The wheel pants look so 1930-ish which I think is fantastic. Kind of reminds me of Jay Leno riding around in a tiny retro-design car. Dan

Yep I missed the spin video and wing unfold. Seemed pretty tame. I wonder if it is a bit elevator limited which can be common with road legal width airplanes. Even Pete Bowers said the Flybaby needed a tail about a foot bigger in span. The biggest issue I have is a big difference between power off stall speed is much higher than even very slightly power on. Like 10-12 mph different. The disturbed air over the low wing root with the prop at idle is where the Flybaby has trouble.
The wing unfold looked pretty easy. Not sure of any potential issues with the aileron reconnection. But like the REMOS accident at Sebring people might find a way..
I do like the wing pivot angle and wing root skin cutout shape. It appears similar to a WWII Wildcat, Hellcat or Avenger wing fold angle and cutout.
The up over the top on the Onex is simpler to build. Whole airplane is simpler construction but it does not appear that this one is intended to be a kit.
The Sonex family is a 6061 aluminum airplane but the Spirit Alclad 2024 aluminum. Sadly though they say the Sprit is 4 G limit 6 ultimate and aerobatics prohibited. The Onex does not have this restriction.
As an alternate this engine may have some other uses for the experimental market. Some other similar size designs. There is the Aeromarine Merlin design and also the BD-6 might still be viable with the right engine.

Onex is a Kit, this comes ready to fly I think that is a significant difference.

I'll admit, I'm intrigued. I would love to get the chance to fly one. Looks to me like it would fit in the storage unit at the end of most common t-hangars. Not sure I'm in the market for a single seater, but maybe one day. I do see in their FAQ they are developing a full canopy option.
For all of the new entries into aircraft manufacturing, this one seems to have its ducks in a row more than most. Not sure how they can manufacture the airframe and engine for the selling price, and they must have a boat load of capital to have 4 prototypes at Oshkosh and another dozen or more almost ready for delivery with hardly a rumor about them beforehand.

Apples to apples, I’d prefer this new design over a Onex. I was thinking a Globe Swift and a Ryan ST had a heckuva hookup..........and made a pretty sharp offspring......IMO

Looks and sounds like a derivative of a motorcycle V-twin engine ?

I thought 1320 lbs was a result of EASA ultralight 600 kg (600 x 2.2 = 1320), thus "proven acceptable and easier to copy" Then again, I don't know if any EASA ultralight have higher gross for amphibians or exemptions like the Icon A5

Brakes work well, then emergency egress. Didn’t seem to have a problem getting out.
