That makes Good sense. Some people have to much time to think. GOOD Job Dave

Long, but read it anyway.
Tension limiter discussions come and go and even the simplest concepts not
only add a substantial cost to each winch an more potential failure points
which could put a winch in a contest situation down for the day, where a
broken line can usually repaired within a few minutes.
Two things that we can do to stanardise winch power, minimize line
breakage and make winches more user friendly are:
1 ) A simple 1/2 stainless steel threaded rod installed between the FLS
and the power from the solenoid can be adjusted to provide the resistance
specs for F3B winches.
Remember that the resistor rod is threaded so adjustment is simple with a
pair of jam nuts. There are a few checking devises for F3B winch
certification that should be available to proof the setup. AMA has one.
The target setup should be the same as current (pun intended) requirements
for F3B winches for a standard and then any winch could be used for all TD
comps,an F3B comp and possibly to run an F3J comp also. The stainless rod
is also unaffected by the heat generated by contest loads and cannot fail
during heavy use.
Also the cost can't be more than $10 to $12 per winch. That reads CHEAP !
I have done this mod thee times and and can testify to it's ease of
installation and cost.
2 ) The slightly lower power achieved above, and I mean slightly, allows
for lower lb test line which will cost less and more importantly allow
some stretch at the launch release giving the pilot a better choice on the
amount of line tension preferred, instead of jerking the sailplane out of
his hand. Also could be an easier launch with the more fragile wood
constructed sailplanes.
This mod has been done 3 times by yours truly with successful results. I
see where Mr Hands Off Retriever fame, Rick Botha is supplying the SWC
comp with a winch resistor system and that will be the start of something.
We have to quit talking about this and get it done.
I propose that we get the Soaring Nats winches resistorised for this years
Soaring Nats and with lighter line than the 300 lb test line that we have
migrated to this last year.
Regards, Dave Corven.
Also Merry Christmas and a Happy New Year.

From what I have seen in this thread, the two real simple, straight
forward
suggesions seem to be, lower capacity batteries like used in B, and
lighter
line, like 200# (which the Dayton club already uses and it works just
fine for
them except they have a great grass field and and no humps in it).
Personnally I just hate downwind launches (my problem huh?) and tension
limiters
sound worse than retrievers to keep working correctly. I am really
interested
to hear how SWC goes to see how Rick's resistor set up works, that might
work
just fine.
I've had my arse chewed on privitaly about somethings here, heh, these
are just
ideas, right? Still wished we all had the B winches though, then there
is no
problem.
Marc
Have a great Christmas, and holiday with your families!
