For a less experienced tailwheel pilot like myself, the combination of bouncing AND trying to not groundloop can overwhelm the nerves. Whenever I fly a tailwheel aircraft, I feel like I'm out there on the edge, the same feeling I used to get when I just jumped something big on my dirt bike.


Zane, pick yourself a nice calm morning and do T&G's until your ready to puke. 15 or more and go right back up the next morning and do another dozen. The only way to get over that feeling and grasp the feel your looking for is through repetition. 8)

Fly It Like You Mean It!

Zane,
Off topic here, but I don't know if I would be changing landing gear until you are comfortable with what you've got now. It might be better if you master what youv'e got then change and have to re-learn.

Re: Characteristics of Oleo gear

Jon B. wrote:To get back to the original question...

I fly a 7EC Champ with what Aeronca (mine's a Champion) originally called the "No-Bounce" gear. They're like the standard gear but have a longer stroke and are nearly fully compressed when the aircraft is on the ground.

They can stand a very hard landing. In fact, my preferred three-point landing is to pound it onto the ground pretty solidly. If you grease it on, the oleos tend to compress slowly as the weight comes off the wings. They also do so asymmetrically, making it feel as though the wind is lifting one wing. It's weird. It no longer surprises me but it still bugs me.

Wheel landings with these is a no-brainer. You can drive it on with power, or come in in a near-three-point attitude then roll it up onto the mains.

Somewhere in between "greaser" and "wham" is a zone where you *can* bounce a touchdown. It's usually caused by too much speed and not having the stick fully back before the wheels touch.

If you (or I) tried to land a Cub, Cessna or Citabria the way I land the Champ, you'd either bounce or break something. Short-field landings are a breeze, cause the thing sticks to the ground and you can get on the brakes. Champs have heavy tails, too, so they stay on the ground with anything short of maximum braking (and you need really good brakes to lift the tail). With a passenger, it would be very, very hard to nose one over. Not impossible, but you'd have to be asleep at the stick, I think.

Thanks for this comment, Joe. I really appreciate it. It was invaluable during my training in the Champion 7EC (1959) with "No-Bounce" gear. Since most of my landings are three-point (ideally touching the tailwheel first), I'm trying to put her down a bit more firmly than I was used to in the J-3 or PA-11—and she absorbs it very well. I'm still getting used to the asymmetrical slow compression of the struts when, for some reason, I'm more gentle with the landings. I’ve learned that if you just stay on the centerline, she eventually levels out.

Question: I'm having some challenges with takeoffs on pavement. It feels fine at the start of the rollout, but around 40–50 mph, she wants to fly. When I begin to gently pull back on the stick, she gets very “squirrely” (I know that’s just above stall speed), and I have to keep her rolling until I pass 55 mph before lifting off. Here again, I feel that asymmetrical decompression, and it feels like an eternity until I finally get some ground effect around 60 mph and start climbing at Vy or Vx, depending on the mission.

Any tips or suggestions? Should I keep her rolling longer?

I'm used to the J-3 and PA-11, and those would start climbing just seconds after the rollout.

Thank you again for all the comments.

Re: Characteristics of Oleo gear

Speaking from basically no hands on experience with said aircraft, I suspect that as the gear is unloading, the camber and toe on the wheels is changing, making it get a bit squirrelly. Try keeping more weight on the mains, then use a more positive rotation to transition through the droop and alignment change more quickly.

Re: Characteristics of Oleo gear

Thanks so much, Kelly. That really helps. I soloed today out of I23 Fayette County and held her on the main longer, until 60 mph, for a smoother transition. She flies beautifully! The winds were very calm, which helped too. I believe the fact that I’ve flown most of my hours in Cubs (J-3 and PA-11) made the transition a bit more difficult. Those Cubs just blast off the runway right after hitting stall speed. I really appreciate the support. Now it’s time to get lots of practice in. Well, weather permitting here in Ohio... lol

Re: Characteristics of Oleo gear

Epic bump…going back 19 years!! Embarrassing to read my own words.

I’ve got a few hours in a 7EC but I never noticed any bad habits during the takeoff roll, just seemed like a pussycat of a taildragger. 1:1 Scale’s theory might be it…camber and toe-in changing slightly as the gear relaxes and swings a little.

Worst case scenario, your airplane was restored by someone who didn’t put great care into rigging/trammeling the wings and the washout is asymmetric.

Good mystery for speculation.

Congrats on the solo! I'm glad that seemed to help.
