Read This, IMHO this post sums everything you need to know about landing a skywagon. If at the end of the day you're not landing sweetly, Read it again.
Contrary to what else I am reading here, I think the 180/5 are really pussycats, and I think they land quite sweetly. If it isn't, you just need to spend a little more time on it. When I have not flown mine for a month or two, it takes me a few shots at it to get back in the game, and I fly largish T/W airplanes virtually every day. That doesn't mean the airplane is challenging, it just means I'm not as proficient in it as I could be.
I am an always full flapper, and wind has never been reason enough for me to change that. Training / playing are about the only reasons I can see that I'd purposefully land my airplane faster than it could be landed. After all, sooner or later you are going to have to deal with slowing it down to a complete stop, regardless of where your flaps are. Why not make the bulk of your landings done in the slowest possible configuration, there by making the bulk of your experience there? If you are concerned about landing in any configuration, that infers you are concerned about a boo-boo. Why not make that boo-boo as slow as you possibly could?
I also don't see any point in muddying this post with tire size. If you can't land a Skywagon sweetly on Bushwheels, you need more dual. Period. And preferably from someone who has been there done that. A 180/5 on big tires is pretty close to the bottom of my list of challenging airplanes to fly/land. In fact I'd say it's almost cheating. That's not meant to be condescending, or to suggest I am an extraordinary pilot. In fact I am very average at best. Proficient? yes, talented? not so much. This is just my honest opinion of the airplane.
Lastly, I don't prefer to land an airplane with it's tail proudly flying like a kite (not really landing, but driving it on), however, I can understand why someone might want to perfect that. SIMPLE.... because he wants to MASTER that wing. He wants to OWN it. I say Kuddos to the guy who sees a deficiency and wants to polish on it, regardless of who else lands there airplane in that configuration.
Take care, Rob
