I've learned that 100km/h is fast enough, our instructors even say 90km/h ist the perfect speed for the 21 to gain maximun high. I had lot of cable breaks this year and no problems with the speed. You've only to react fast enough. And the 21 is a very friendly flying plane (with our other planes, especially the ASW19 I prefer higher speeds on winch launch) and you normaly are not pulling the stick full back before you reach the safety high. What do your instructors say about using back-stick in the K21? I just did my annual winch-launch checks and mine wouldn't let me use any back-stick at all. A K21 will still launch perfectly well like that but I *know* that I'm not getting the best out the launch like that. On the other hand my instructor did play a neat trick on me - he distracted me by suddening say "look at that plane!" and pulling the release at the same time. I *did* hesitate in getting the nose down and even though it was only a small delay by the time I'd finished the push-over to the recovery attitude there was only 40 knots on the clock. Took a fair few seconds to get the speed back up before braking down to a straight-ahead landing. That was a bit of an eye-opener, to be honest. Dan |

Well, if you have the stick fully back (which I often have, and don't object
to with my students), you 1) are above safety altitude 2) pay attention. Bert "Dan G" wrote in message ...

What do your instructors say about using back-stick in the K21? The same as in any other glider: Use as needed to keep your target speed. |

That's what I think but I put this specifically to the full cat* I was flying with and he disagreed, saying "you'll risk spinning on the wire" if you use "any" back stick in the K21, and that you should ride the speed with the elevator neutral throughout the launch until you need to wave-off (signal the winch driver to slow down by waggling the tail). shrugs . Dan *in the UK there are three categories of instructor: "full" is the highest, the others being "basic" and "half" |
