Can you tell me what "Prop to Use" on
Knowing the cubic inch
displacement of any given engine will help decide approximately
what size prop you should start with. Sometimes
we can give you an opinion or two, they are Free as
usual, but they are only opinions and not the Rule.
The first place to look
would be in the Factory Operation Manual. You
will notice that they don't even give you a Hard Line
Fact, they give you a selection of what to start with
and where to go after the engine is broken in.
This is another Iffy Science and there are a million
opinions covering the question.
What type of airplane it
is will affect the selection. What you want it
to do, like go Fast or Climb Strong, affects the selection.
Even the type and brand of prop you choose will affect
the performance. What altitude do you fly at?
All these things will affect your selection.
We won't let you try to
put a 12-6 on a 4.2 Gas engine but we can only make
suggestions, we are not the prop experts. Your
best bet would be the manufacturer, who would know better
than the person that built and tested the engine.
