Ant,

If you bounce after a smooth landing then you still had flying speed....there is no other force acting on the plane that will cause it to leave the ground (unless maybe you hit a bump or something). Some jets just have to land at or slightly above stall speed or they have a tendency to bounce. With these type of planes I just tell myself (once close to the runway) "don't let it land". Hold it off until it won't fly anymore and when it touches down it will not/can not bounce unless you drop it in from several feet. It's a physics thing.

Now this is not to say that gear placement, wire versus oleo struts, cg, length of nose gear (i.e.ground angle of attack) and other issues will not effect a plane's landing characteristics. I'm not familiar with the Starjet and if they are not known for bouncy landings then one or more of these factors may be off.
