 RR> The biggest problem on a winch is breaking the wing from too 
 RR> much power on the winch. 
That's what I meant when I said the Corndogger was too light for 
the winch. It's simply too easy to inadvertently overload the 
glider.

 RR> How long a high start? Most of the time we use 1000ft high starts. It
 RR> seems the shorter ones don't get them up high enough. 
Mine has 33 feet of rubber and 200-300 feet of string which is 
trouble enough when other people are using the playground; the 
longer ones (100'/500') are worse in that respect. Since I prefer 
slope flying to thermalling I use the high start only when there's 
lots of sun, no wind, and no people. It typically takes me several 
launches to find a good thermal but I'm not very practiced at it.

KB>  I now attach the wing with rubber bands.
 RR> The rubber bands are the only way to hold a glider wing on unless
 RR> you've got a scale ship. 
Yes, rubber bands are good but my Corndogger uses 4-40 nylon 
screws which also work well. I even used velcro for one 
incarnation of that styrofoam glider and the velcro did its job 
nicely though other aspects of that wing attachment method had 
problems. 
 RR> It sounds like you totally rebuilt the foam
 RR> glider, wouldn't it have been easier just to build a kit |-). 
Nope. I put less effort into that styrofoam job than a 
conventional kit or ARF would have required. But the object isn't 
just to build a glider; it's to try new things and learn what's 
possible. And that styrofoam glider gets more attention at the 
flying field than all of the other gliders put together. Try it; 
you'll see what I mean. 
 RR> Anyways, at 1:30AM it's getting late so I'll say bye and TTYL
Happy landings.
