Is there software available to visualize helicopter dynamics in Matlab/Simulink?

[sodemus]

I'm simulating helicopter dynamics but would like to better visualize the behavior of the helicopter and so I'm looking for some existing software solution. Ideally this would be similar to an aircraft simulator which would be rather taking position and attitude time series as input instead of computing the dynamics/trajectory itself. I'm using Matlab/Simulink for Simulation so obviously a Matlab package would work if it's not too much of a hassle to set up.

This is a pretty generic problem so I'd be surprised if there wasn't anything out there...

Thanks in advance!

I ended up using a pretty neat thing I found here:

Brian turns out to be really helpful as well.
