Pusher Vs. Puller
Is there any noticeable speed difference when using a pusher/puller engine in a plane? This is assuming the exact same plane but with just a different engine orientation. I am also just looking for an answer on 2 stroke side exhaust front intake engines.
The only things i can really think of is that the tip of the muffler should act differently since it would be placed into the airflow instead of out of it and that the carburettor may not be getting as much air as usual but this is unlikely. otherwise the engine should still have the same area to it for drag to act on and there may well be other little things that affect it but I'm looking for some real world feedback.

RE: Pusher Vs. Puller
I've seen several pushers, and I have one myself. Actually....if you consider that the
carb is mounted behind the engine....and in some cases the muffler is pointing backwards
the engines do a fine job. In fact, I have seen them screaming their guts out, when
you would think they shouldn't run very good.....
....perhaps not as well as an engine mounted normally, in the front. In fact, I have seen
them running long tuned pipes....and the performance was not hindered, even with the
engine and pipe mounted backwards.
Strange, but true.
FBD.
