Re: [RCSE] Do you like long wings?

Just because you CAN break a 300# line with a 3M 90 oz plane, doesn't mean 
you need all that force to launch a 5M.  I believe the expression is 
"touch".


Hi-starts are normally sized to pull about 5 times the weight of a plane, so 
a good launch tension would be 5*185 oz or about 58 pounds.  Get radical and 
double, even triple it.  Still under 200# pull.

And, how are you going to launch something like this? 65-90oz models are 
busting 300lb test line.




How about a 5M (195") TD model?

Launching models this size is very difficult, especially if there is 
any wind.  In 1979 I designed a sailplane with a 169 inch span and 
flew it in unlimited at the 1981 and 1982 Nats.  The Dragon Lady was 
a real handful to launch in any wind and  I finally retired it from 
anything except cross country.  I launched the model myself at both 
Nats but I really needed a pit crew.   There is a photo of the Dragon 
Lady being launched in the SOAR report for the 1985 Great Race.  I 
was flying, Ed Wilson was throwing, and a team member was on each 
wing tip stabilizing the model.   That was on the first day before 
the high winds that year.  We didn't even try to fly it on the windy days.

I just posted the link, I am not worried by little details like that...  ;-)

(A better question is how would one throw that model?)
