There was a 'lone ranger' who built a remote controlled winch 20 or 30 years ago. He could launch himself with no help at all. I'd like to know more about that winch. Bill Daniels |

CV Actually, I'd contend this causes most wing drops since it's usually not evenly distributed over both wings. |

We're talking about a winch, CV. You don't have to wait until the speed builds up :-) - mark |

You need to be "very very" quick on release if the down wing
does not move forward with the winch launch as the upper wing starts flying and lifts up and can throw the glider/you into an end over end cartwheel, fatalities have happened with that scenario. The winch rapid acceleration is a two edged sword ,as long as you get the wings both moving forward its easier than a aerotow wingdown takeoff. gary "Mark Newton" wrote in message ...

You prop the wings so they're level. - mark |

The point is this "cartwheel scenario" has happened before.
I believe there was a case in Europe not that long ago. gary "Mark Newton" wrote in message ...

If a wing tip catches on something like tall grass, the combination of high acceleration and CG hook can be disastrous. This sometimes results in a flick roll and inverted crash. This is why the takeoff area of winch operations needs to be smooth and the pilots 'spring loaded' to release if the takeoff roll swerves. If the takeoff surface was smooth asphalt and the glider had tip wheels or low-friction skids then starting with a wingtip propped up on a stand or box might not be so dangerous. It pays to be careful though. Let me add just how sweet it is to accelerate and lift off without the turbulence, noise and dust of a tow plane. Compared to air tow, a winch launch area is downright civilized. Bill Daniels |
