RE: Do the flight characteristics stay the same..
Guys, here is one for you...........If you look at the missile rails on the A-7, you will see that they are angled down about 5 degrees and they are AHEAD of the CG. One would think that putting a sidewinder on them would cause a pitch DOWN moment....Nada.........The first time I flew my A-7 with them, it rotated on it's own!!
Another thing.....My A-7 flies faster with four 1000 pounders on the pylons....no trim change. It seems to land slower though. The bombs are very light and they definitely add more lift than weight to the airframe.
Tailwinds,
John
