Mackey SQ4

[Oregon180]

I've seen various references to this beast, which I presume is a 4-seat version of the awesome Mackey SQ2, but can't find any specs or pictures of it. The kit was recently approved under the 51% rule.

Does anyone have any info on it?

Just curious.

Yep, but couldn't find any pics or specs on there.

I'm not looking to build a plane, just think it sounds like a cool ship.

Wow, those are NOT cheap.

Wayne's stuff is ALWAYS really cool, and it performs. I really appreciate that he's pushing the envelope for this specialised, niche type of flying.

Thanks. cubscout

I never really appreciated just how big of a difference the little things could make, until Wayne put my fuse in his jig and 'optimized' it. It was only 2 years out of a prior rebuild, and was not bent, twisted or even out of rig, but was getting recovered due to hail damage. The difference in performance after Waynes work was astonishing. If I were in the market for an exp cub type, hands down, the SQ2 would be it...
Take care, Rob

I'm very impressed with the plane. The performance put on at Valdez was impressive to say the least. I wonder what kind of headwind they have at those stol contest. The SQ2 if I recall landed in under 60 feet and took off in under 80 feet.

This video claims 13mph

The 96' ASL elevation doesn't hurt either. Wonder what the temps were?

That is the ultimate short spot landing, expertly flown besides having the right plane for the job We can all just quit right now and go home!

Excellent throttle work on the spot landing. I wonder why it has taken us this long to get here?
Compare it to this from the late thirties.
If you find the choice of music politically/historically offensive, turn it down. Fantastic demonstration of aircraft ability worth watching by the people who built it. http://www.youtube.com/watch?v=-DzdJg3i ... ature=fvwp

The Piper Cub is a super plane all by itself. With the slotted wing it seems to just hang there. What are the other mods?

[WingsOverPalawan]

Definitely a very capable plane.

What does the "SQ" stands for?

[Oregon180]

Hi RidgeRunner.

"SQ" stands for STOLQuest. The SQ2 truly is amazing, and I can't wait to see what the SQ4 is like. Having even a fraction of the SQ2's capabilities in a 4-seater would be truly cool.

Here's a nice interview video from EAA with Wayne talking about the many mods he incorporated in the SQ2:

It appears to me that the only way to get it down where he wants it is to basically drop it onto the ground. Most planes are not designed to land on their tailwheel, or drop the mains onto the ground regularly. Even for the SQ, that can't be good for the rest of the airframe, and also the wings. What about metal fatigue and cracks?

I reckon for most folks that build the kit it would usually be regular ole grass field landings but nice to know it's capable of flying like a helicopter for getting in short. Looks to me like the tires and shocks take the load well, but I'm no engineer and that plane was probably light on fuel and luggage.

Could be a different day in the same location but it doesn't seem that the SQ2 needs any headwind. 2:00 minute mark is a particularly nice landing and at the 3:00 minute mark. On this day he takes off and lands in all different directions into the wind and with tailwind.
