Those still interested
I know lots has been said about this.
I have a 912S in my plane. The carburetors are inclined to overflow when the
engine
overheats after shutdown or when the engine runs rough . The overflow is
vented to the airbox. """It must be vented to the airbox !!!!!"""
In a 914 the airbox is at bust pressure and so venting is not done, it just
overflows
into the "catch trays/ heat shields".
The other thing I took notice of -- The RPM to run the Rotax at in cruse.
There
is a misunderstanding here. Some people are thinking "fixed" props, and others
are using "Constant Speed" props. I always cruise with my prop set to "cruse"
This is automatic control of pitch to make the tach read 5000 RPM. If
I choose to reduce power to, say, 4 US gph, I still have 5000 RPM on the tach.
If I remember correctly I can get to about 3.5 US gph before the prop can not
keep the RPM up.
Now did that explain the differences??
