The RV-12 is a great "slipper"! Full x controls present no problem, no limitations stated that I am aware of and no bad habits when you do.

Correct… you can cross full controls, even with full flap extension, and when released, it straightens itself back out nice as can be. What it doesn’t do very well is scrub off speed when in a slip. POH suggests 55 KIAS on short final, and if you carry any extra speed, the plane floats in ground effect with air being compressed under the low wing. 55 KIAS allows enough energy to be converted into a nice flare for landing...

I too slip the 12 almost every time I land. Partly because I misjudge the configuration point, altitude, and descent rate, but mostly because I enjoy slipping the plane!
A very interesting thing on the last long slip to land I did recently. A few days ago I did a particularly long slip while turning and descending from a right base. From 1500 agl down to the runway with a full cross control slip locked in the entire time. At some point during the slip, I looked down at my Garmin "wind indicator" and it showed an almost 30kt crosswind!
I continued the landing, took a look at the wind sock and it showed a nearly calm breeze straight down the centerline. The Garmin continued to show a crosswind and I landed and rolled out and then switched to "wind not available" by runway exit.

My theory is that with such a prolonged slip, and while turning in the descent, the Garmin decided that the strange airflow through the static and pitot tubes as wall as the flight path over the ground, must of meant a very strong crosswind.

Anyone else seen this?

The EFIS displayed cross wind is based on a calculation of your GPS ground track vs magnetic heading. A long duration slip would cause the calculation to indicate a cross wind even if there wasn’t any.
Strange airflow would not be involved.

That makes much more sense. Thanks for the clarification Scott.

I don’t know about you guys, but on final 99% of my eyeball capacity is out the canopy. Not pondering the fate of the universe and what the EFIS shows for Xwind!😝

Yes, the RV-12 is a pleasure to fly in the landing pattern. Once slowed on downwind leg, I drop both notches of flap in one smooth motion and trim for 55 KIAS with power at idle. Airplane is fully configured and flying hands-off well before turning base leg. Airplane holds pitch attitude and maintains glide slope with very little control input. Beautiful to turn final and be lined up with centerline and follow it to touchdown with only quick glances at airspeed to just to confirm. Never gets old and always brings a smile….

Default Forward slips

Here's a nice YouTube video about forward slips in the 12.

I did my transition training in a 12 with a 2 blade. My 3 blade 12 iS for sure slows down faster and i have to carry power just a tiny bit longer in the pattern. I shoot for 75 abeam the numbers and add in all flaps, trimming for 65. When i get a little more confident I’ll shoot for 60.

I was taught to use a far amount of down elevator in the Cherokee trainers when doing a slip. Man I was surprised when my 12 picked up quite a bit of speed when i did that.

Still, this is a super easy plane to land!

I fly off a 7000’ concrete runway. I carry 65 KIAS and one notch of flaps on final and bleed it off after the flair. It gives a bumpless squeaker every time. I save 55 KIAS finals for shorter runways.
