Took a hop yesterday after work; pretty rusty, but I finally got some good control, slipping it on to wheel landings (wind about 40 degrees off at 9-10 kts). The evening sun was a problem- should've dusted the windshield first, at least- even my beloved Ray-Bans were no match for the glare. The Champ has a high windshield, so there's nowhere to hide, unlike in a Cessna... so everything was OK until the flare.

Started with a 3-pointer; easy.
First wheel landing was good attitude and speed wise, but I was hunting, so she bounced.
Did some more 3-pointers, then bounced a wheel landing again.
Bob took over on the next, with me paying close attention.
Then I did one, the right way. Chirped it on , chopped the throttle, and just shoved that stick forward. For a 200+ -hr trike driver, that is a triumph of the will- and scary!
But as the tail came down, I was elated- it was a good one. And I was rolling out just fine...
Then she abruptly weathervaned or something, faster than I could correct. Not sure what Bob was doing, but I rammed right rudder, which seemed to help at first, but in no time we were rolling left onto the dirt, the plane seemingly eager to whip its tail and put a wingtip on the ground.
Tower asked if we required assistance, and the Champ was still lurching and sliding, or so it seemed.
No apparent harm done, I got her onto the taxiway and had another stab at it. Almost did a proper wheel landing after that, but after 1.2, with the ground getting darker and the sun right in my face in the flare, I decided I'd had enough.
Bob was very sympathetic about the near-disaster, and the consensus was that it was best my first "excursion" happened that way- with him aboard and with no damage. :D

I had heard more than one pilot say "after it swings about 30 degrees, it's going and that's that..."
Now I understand that completely. As Bob said, chuckling: "That made a believer out of you..." :D

Another interesting thing: noticed after the flight that the tailwheel spring on the right side had come loose again at some point; Bob suggested it may have contributed to the loss of control, but maybe he was being kind. :rolleyes:


Back in the saddle again Sunday morning...gonna do at least one really fine landing, I can feel it. :yes:
 
Sounds like the best lesson you could have asked for in a checkout.
 
id say not having the spring on the steerable tailwheel could lead to some major directional control issues.

I wish I knew at what point it came off- it was fine before takeoff.
It's possible it came off during my little "detour"... but I'll take it as an excuse. :D

The one ground loop I've had (so far) involved the loss of both tw springs (and a gusty quartering tailwind). I was all over the runway and almost saved it, but it finally went sideways at something like 5-10 mph. IMO, losing one or both tw springs can make things really interesting.
 
yea i was thinking about you lance when i posted that, but figured id let you say it :)
 
On all of the tailwheel endorsements I"ve done, I've managed to allow a groundloop. It's a situation where I know the airplane is somewhat manageable, and we're heading to a known "safe" spot on the infield, so I let it go. I talk them through the appropriate responses...a short blast of power, full back stick, some aileron to help slow the groundloop, and maybe even easing off the correction just a bit to clear a runway light (you know...fly it til all the pieces stop moving).

Afterwards, we fly one more good pattern and landing to get a little confidence back, and then to the hangar for half an hour of ground school on the how's, why's, and wherefore's of groundloops while it's still fresh in the student's mind. We talk about the things you can do to minimize damage (some of them we did, but you can't do them all in the amount of time it takes between starting and finishing the "maneuver" ;)). Then we go fly some more.

Seems like it makes them a lot less fearful of groundloops, and reducing fear makes a student more capable of learning.

Fly safe!

When you jambed full right rudder the tailwheel was full left and you pulled the spring beyond the point it could returnto its prior lenght.

happens all the time.

What I didn't mention in that post is the fact that the springs had just been installed by another co-owner after he purchased them from Menards (mine was the first flight with the new springs). IIRC one or both springs actually broke, no doubt sometime during the landing.

You know, I haven't asked if Bob was actually helping me or not on that one- I'll bet he wasn't, even though I assumed (hoped?) at the time that he was. :D

It's definitely good to have one minor "excursion" out of the way, with him aboard just in case. Very, very educational.

That makes a lot of sense. It's taking a while to intuitively understand what's going on back there...
