Hi,the P51 I showed in the landing thread flies a lot better when I added 5 Lps o led to it..It was a little bit "flimsy" when i tried it first without adding this weight..
The Sist FW190 is a very heavy bird to but has no trouble carrying its weight,roughly 25 Lbs..
As far as I can tell(i´m no pro though),smaller aircrafts are a lot more sensitive to high wingloadings than larger ones..
