Off course not....but RV's have been lost doing unusual attitude maneuvers, why test it over and over.

The FAA has de-emphasized (somewhat) stick and rudder skills in favor of using your head to stay out trouble.

I am in favor of both.

A skid does not require cross-control... that's a slip.
Try a banked turn at low speed and add inside rudder... now you'll be upside down.

Found this video on skidding and slipping stalls turning final....

https://www.youtube.com/watch?v=zfwLglHEYvQ

Interesting....good reason to fly with ball centered.

Apologize for ruffling feathers here, I am getting old and crotchety and know it.

Best thing going on right now is helping friend complete an RV-12. At present installing flight control system and getting spun up on "flaperons" and how they work, quite different from RV-7 and 8. Understand flap feature as of today but still have to discover how ailerons get moved.

Before that was task of unraveling rat's nest of wires from option and fuselage bundles...finally traced every wire back to connector pin and then went to diagram to find out what it was for, labeled it, and made sure it was routed correctly. The 12 is not an easy airplane to build. at least not from perspective of stepping in at chapter 31. It has many more wires than previous builds.

Doing a Flight Review tomorrow with hangar friend and neighbor in his 12, will be first time in it for me, I've heard it flies like all RV's, will find out.

There was some cross-control involved ... some alternate aileron to keep the bank "relatively flat" in the turn -- a low bank, skidding turn. Agreed, not like regular slip.

the point of the video was to practice keeping the ball centered in the pattern. it doesn't matter how well you recover from this stall at altitude because if it happens turning final there is absolutely not enough altitude to recover.

RV-12 is a delight to fly....not quite the git-up-and-go of the RV-8 but flying qualities are excellent.

Was very bumpy day ahead of weather system but all went well, no skids or slips to final...

Not to intentionally beat a dead horse... But I work for a Part 121 carrier and was in the Simulator just last Monday. We are taught "approach to stall" recovery instead of actually stalling the airplane. Basically, fly to the stick shaker and recover. It's rather bland. Our Sim Instructor did tell us within the next year though, 121 carriers (all airlines) will be required to train recovery from a full stall or deep stall. It seems the FAA is changing its tact on weather to just avoid hazardous situations or teach and practice real recovery. But it's just a rumor I guess, I heard it from a pilot.

And I am for it. There's seems to be a quiet, self depreciating joke among my co-workers (all 'top of the pyramid', ATP holding, Airline Captains) who don't fly GA that "If I were in a small plane, I'd probably crash". I think they're right. Staying in the middle of the envelope for an entire career dulls your skills. I know all the tailwheel, aerobatics, banner towing, formation flying makes me a better pilot and certainly better at my day job. Finding the edge of the envelope once in a while is perfectly fine and teaches you a better respect for what we're doing in the sky. As long as it's done smartly and safely like 7000' and not 300'. There's nothing wrong with that.

P.s. The DC-9 simulator does wonderful aerobatics. Rolls a little slower than the RV, and doesn't really like to spin either

David, no feathers ruffled in my opinion. You started a healthy discussion. We learn from such things. If we stop learning... it is downhill from there. And good on you for helping out with a build. That's the spirit!

Upset Recovery Training, or some Aerobatic Training is the best way to learn how to avoid (and recognize if you are getting into) stall/spin situations.
Flight instruction does cost a few $$$, but is always fun and well worth doing.
I joined the IAC and flew my RV-8 in Primary Class in 2016, it was a Hoot!
