My aerodynamic question had always been why there are fewer pusher

airplane.

In a pusher, the prop has to operate in turbulent air stirred up by the
structure in front. *Depending on the design of the airplane, the prop
also has to be stronger (e.g., heavier) to withstand the cycling loads
if there's a wing or something blocking part of the prop disk from the
slipstream (think Long-EZ).

Thanks! I seem to remember the pusher in the C310 was less effective
too.
