I remember pondering the idea of a wood prop some time ago. Due to the saving
of a few pounds of weight in the very front of the plane (long arm) there is
the need to check what would be the CG at gross, as it will move towards the
tail, and may reach or exceed the rearmost limit. Obviously, this depends on
the specific plane.

Joey -
I'd be hesitant for a couple of reasons:
1. Wood props are less efficient. With your having 75 hp, I'd think you'd
see rate of climb drop and cruise speed drop a little. Do you want to see that?
2. On a tricycle airplane, your more fragile prop is close to the ground, to
pick up more FOD damage than when wood props are used on tailwheel airplanes,
where they're up higher off of the ground.
3. Of course, the wood prop will be lighter, so you may gain some small
amount of useful load, but again, performance will suffer.
Just my 2 cents.

I am thinking about replacing my metal McCauley 7351 Prop with a new
Sensenich wood prop,a W74FK-45 Std. Has anyone had any experience with
a wood prop on a 415C with a 75Hp engine,
Thanks
Joey
