Comment #14 on issue 439 by colin.d....@gmail.com: Piper Cub model has  
unrealistic performance

OK, I just did a climb test of the changed model myself. It's definitely  
closer to the real thing now; at max gross of 1172 pounds, a full-throttle  
climb to 5000 feet at the best climb speed (which for the changed model is  
57 mph) took 11 minutes. For the old model at the same weight, at its best  
climb speed of 55 mph, climb to 5000 feet took about 8.5 minutes. So things  
are definitely better than they were.

A look at the YASim command-line solver confirms the change in performance:  
the "lift ratio" figure is less than half of what it used to be.
