Yes they are. But now that you mention it I've been playing around with them,
trying to get a better look. Here's a screenshot:

This is with the submodel entries shown below. I turned off the <wind>, set
the x-offset further aft (maybe could go further still), added some speed to
aft, and decreased the delay to 0.04.
I had the delay set to a much higher number before because I was timid with
the use of the submodels, knowing that a smaller delay would result in many
more instances of the submodels. With delay set to zero I get about 650
submodels in existance at any time. With the delay set to 0.04 as above, I
get 340 submodels. The high number of submodels seems to have no effect
(that I can tell) on frame rates.
