We've been saying it for years, and not enforcing it. If a guy breaks
the line and isn't made to fly it out, he hasn't learned anything. I
like Mike's solution. Limit the motor power to below line strength.
Launch mentality and techniques would change, but the competitons would
run smoother
If you come to my contest, you'll be launching on 180# line and if you
break it, you'll fly it. Just because you have no skill, just brute
strength, is not my problem, either. So who says we have to cater to
your HIGHER line strength needs. There is something in the rule book
about the CD
Back when we were using 6-V batteries, and 80# line, there were 140 and
150 models, and they outlaunched everyone. I see no need to limit the
unlimited class... only the launch power. In this scenerio, I see no
other sloution that allows everyone to launch from club equipment and
keep the contest

Mark, I have no problem with any means selected to stop the killer winch-pull
escalation. You have been in this game a long time and I respect your opinion
on WL's, (even though I'm not sure what makes it not really work). I do feel
that this RCSE thread is all just talk and next build season
Someone, might have been DP, brought up some good points about launching
into thermals, gusts, etc. A flyer might be doing his best to pulse up
and save the line and break it anyhow... I like the 180# to 200# line
suggestions, but most of all, I like the limited winch power
suggestions. Of all
Actually Ed,
If you get a line break you fly it at LISF.
As for new line we don't normally put on fresh line anymore. We
discovered that new line had more breaks than older line, unless it was
really rashed up. A lot of the Memphis Twine has bad spots in it.

Great idea Fritz. I know you do that for the CRRC contest all the

turnaround.
Plus it points you directly at the downwind thermals.

Do I really want to believe this from someone who keeps the pedal down
even on his Easy Glider? His winch must have some kind of optical
recognition because it only breaks other people's planes. Or, at least,
it only breaks planes when other people are launching them.

It does lead to excellent power for those that know how to use them.

most.

Do we really have to winch with full pedal all the way up the line? Remember,
the more line we take in, the less altitude we can get. If the flight window
starts after we get off the line, I don't see a reason to rush the launch. I

With all due respect I disagree Jeff.
At our local field when we launch to the north, it takes all the line off
the drum.. We get much softer, less powerful launches.. As opposed to when
we launch to the south we still have approximately half the winch line left

Another way to reduce power - go to batteries with lower CCA rating.
Make sure you get as much reserve capacity as you can to get more launches.
Lower CCA batteries have a higher internal resistance - less power.

My intention was to say that, in order to remain competitive, you will likely
find it necessary to go to stronger, more expensive planes. This makes it
harder for sport flyers who do not have big budgets to enter into a
competitive
position.
Harder? Sport flyers are competitive the minute
You are all correct.
If you go to an extremely small drum and never launch with a lot of
tension, and it's not windy, you will probably never build up the
tension to get the small drum to break the line.
But if you put a lot of tension to start and have a good setup and some
wind, you can

There have been various proposals about limiting winch current via a series
