I played with CG changes on an F-18C and on an F-18F. I incrementally removed a strip of lead from the nose and flew it. It passed the so called "inverted" test. (Once again, my ignorant self only really knows this one [sm=tongue_smile.gif] ) But the F-18f turned into an absolute bear to land, while maintaining civil flying properties.
Funny how the super hornet displayed these characteristics before the non super hornet. After discussion with you smart folk of RCU, we blamed it on the decidedly large and prominent leading edge extionions found on the superhornet as compared to the non super hornet.
Needless to say I added lead back to both Hornets!
That was pretty different than any other airplane (jet or non) CG changes I've tried,a self admitted small number though! [&:]
