Holy Cow....

I took off one of my blades today ( I added the spacer blocks )

I did a static run up to set the pitch....

Thought it was good....Went flying around the pattern....

The "R's" wouldn't get has high as I wanted....

But HOLY COW....I was Hauling azz....

I landed and took a little "bite" out of the prop ( 1/2 turn )

But it was too much , so I put a quarter turn back into it.....
Something I don't understand....

When I folded the plane up at the end of the day (cheaper hanger rent)

The aileron tubes were being "bowed" from pushing on the prop....

I ended up putting the prop straight up & down....

Does anybody elses do that....I built that area "Stock"

Maybe only the Tennesse prop will fold like that ???

Mike,
The wings should fold the same as they did with the three blade or is
this the first time you actually folded the wings? Perhaps you can
solve the problem by changing the aileron position?

I might be wrong Mike but I raised my engine a bit to avoid the two blade prop from hitting the aileron tubes they were close but not bending anything and there is not much of a change in flight characteristics
if you ever haul your plane on an Open trailer don't have a two blade in the vertical position or you will be patching the fabric on the bottom of a wing I didn't do it but I know of another guy that did just that just trying to be helpful

Mike,

I fold my Firestar II with Ivo 2-blade prop and prop. extension. With
the prop horizontal, there is a little over 1" clearance of the prop to
the aileron tube on each side. However, the ailerons are folded down.
If they were up, there might be a problem.

I always fold mine with the prop horizontal as it won't fit in my garage with it vertical. I have an Ivo 2-blade.

It was a nice flight yesterday with smooth air.

Thanks Guys....

I forgot that I had my ailerons straight up instead of folded inside the tail area....

I've been doing it that way so long because of them rubbing on the
tail surface during transport... ( it didn't matter with a three blade )

Yeah, the IVO prop is like that in the typical 2-blade configuration. It tends to be stalled when run static, giving an unreliable load when running it on the ground. Once airflow starts going through the prop disk, the blades unstall and you get the actual load you'll see in flight....

Kind of a pain.... you have to do the land-set-fly-land-set thing to get it just right....

My FSII has a 3 blade prop and the original builder fashioned a little boot that goes over the blade that sits between the wings when they're folded. That keeps it from tearing up the fabric.

About 6mos. ago, though, I transported the plane from TX to new mexico on its open trailer (don't ever want to go that far on the open trailer again) and at the end of it, the prop had put a depression in the fabric on the one side. I run the clutch so the prop was free to freewheel up against the fabric...

oops.... fortunately, going over the spot carefully with a heat gun took the "dent" right out....

I've read about a guy putting a hole in his fabric with the prop...

So even with the 3 blade set-up I've had a "foam block" that slips

onto the end of the prop , and it rests on the boom tube....

One thing about this site....You can learn from other peoples mistakes.

and prevent it from happening to you... ( sometimes )
