why should the tailhanger undercarriage design be inherently stronger than the tricycle? For the mains, no real difference. You do take some of the shock off the mains with a taildragger if you make a stall-down landing, where a bit of the weight is borne by the tail wheel. In a trike, you never put weight on the nose wheel until the plane is rolling on the ground. But it is certainly more difficult to build a strong nose gear than a strong tail gear. Do take-off/landing characteristics have anything to do with it? With propeller aircraft, does the tailhanger design lend itself to easier takeoffs and landings? Quite the contrary. A trike is easier to taxi, easier and safer in the takeoff, and very much easier and safer on landing. The major exception would be rough-field landings, where a wheelie in a taildragger is more likely to have a happy outcome. It is not generally recognized that the tires on a J-3 Cub are low-rent "tundra tires" -- they're soft, to absorb rocks and ruts in the fields that were common when the plane was built. The Hurricanes of RAF 17 Sq retreated from Rangoon in March 1942 to a rough field some miles north of the city. Several had their tail wheels torn off by rocks; they were replaced by bamboo skids. all the best -- Dan Ford email: (put CUB in subject line) see the Warbird's Forum at www.warbirdforum.com and the Piper Cub Forum at www.pipercubforum.com |

I'm always amused at the thought that I fly a taildragger but fly the plane right onto the ground,
Were you originally taught to land that way? I first learned in a J-3 and was taught to three-point it. vince norris |

I used to do a lot of taildragger conversion instruction and always started my students with full stall landings. They would not learn wheel landings until they were comfortable and competent with full stall landings under nearly all conditions on paved and dirt strips. Wheel landings tend to become a habit for some, a bad habit in my opinion. Regular "wheel landers" tend to get a bit lazy, land a bit too fast and long, and lose the skills of low speed handling that landing a tail dragger requires. Rick |

Gull wings, a.k.a. F4U Corsair series. A couple of points, he 1) A conventional gear isn't necessary for prop clearance. All taildraggers have long enough landing gear that the prop will be some acceptable distance from the ground when the tail is raised on takeoff. I've yet to see a Mustang or Corsair take off in a 3-point attitude. (You wouldn't be able to see the runway, and the rudder would be blanketed, just when you need it to keep the pointy part forward. 2) If the Corsair needed Gull Wings to get adequate prop clearance, than howcomzit that the F6F Hellcat, with an identical propeller, (the prope wer interchangable. F4Us flew with F6F props and vice versa) was able to make do with a flat center-sectioned mid wing and landing gear retracting into the wings? And, in the process, provide better takeoff an landing behavior? I think that if you really look into it, the reason for the Corsair's wing design was a desire to reduce interference drag at teh wing/fuselage junction by making sure that the wing met the fuselage at a right angle. The inverted gull shape allowed this to be done without having to add a lot of fairings to the joint. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |

I first learned in a J-3 and was taught to three-point it. No, the wheelies were very hard to learn. Come to think of it, everything was hard to learn. I guess that's why most training is in trikes. all the best -- Dan Ford email: see the Warbird's Forum at www.warbirdforum.com and the Piper Cub Forum at www.pipercubforum.com |

Having spent a few thousand hours flying in the Idaho and Montana backcountry in both taildraggers and trikes including 206's and 210's, I have to call BS on that one. I will take a 210 into nearly any field that I would not think of wheel landing a taildragger. For one thing, a wheel landing requires a higher touchdown speed, imposes greater loads on the gear and airframe, and burns up runway that may not be there to begin with on a rough field. Try wheel-landing that cub on a field that is rough and sloped a few degrees and you will trash it in a hurry. A trike can be full stalled as well as a taildragger and in the case you mentioned would nearly always come out the winner in that game over a wheel landing. The ability to stand on the brakes without worrying about a noseover also leads to a shorter rollout than a wheel-landing taildragger. Rick |
