Guys,
I'm building a firestar2 with a 503 DCDI 2.58 B gearbox and considering the
Powerfin prop.
Any opinions on 2 blade vs. 3? Also those out there using this prop, what b
lade type/ length are you using B,C, or F combo. Just looking for info to m
ake the right decision for me. Thanks,
-Gerry

Gerry,
? You might want to consider the mass weight inertia of all 3 blades types before
you buy. The B -Box has some limits.Most on this list favor the Powerfin or
Warp over the Ivo, but the Ivo is the lightest I believe.

Gerry, I have a Powerfin on my HKS powered trike. The blades are light so
the inertia is low, a good match for the limits of the B gearbox. They are
easy to adjust accurately, and the factory gives very good support. If they
have a weakness, it's that they are not terribly robust if something hard
goes through them. I wiped out a blade when I forgot to take my glasses off
my collar and the slipstream sent them flying.

The setup on my FS II is a 3 blade Power Fin, Model F; C gearbox (3.47 ratio) being
driven by the R503 DCDI/Dual Carb.

I fly a powerfin on a Trike also, its a great prop. We replaced the wooden prop
that came on the trike with the powerfin. The Powerfin gives more thrust, is
smoother, and is quieter. Better than the expensive french made wooden prop
in every way.
I have a Warp drive on my 912-S, its very strong, exactly what I want for when
something goes through the proppeller as does happen with pushers from time to
time. I also love the nickel leading edges for flying through rain. No leading
edge tapes to mess with and I can fly into a thunderstorm with confidence

I think both props are great !

Friend of mine back in TX ran a tennessee 66x34 woodie on his FSII 503 B box and
it worked really well.
My FSII had the 3.47:1 C box on it with a 3 blade warp drive taper tip in 68" diameter.
I could outclimb my friend's FSII but only by a very little bit.
Judging by those two planes, tho, my suggestion would be for a 2.58 ratio stick
with a 2 blade of about 66" (i.e. the F model powerfin would be pretty good.
The tennessee woodie is great too but may vibrate a little more). If you go 3
blade, I'd suggest gearing down to 3.47 with the C box and running a 68" warp
drive. I tried a powerfin F model 68" 3 blade, but the warp drive worked a little
better overall.
I'm also an RK-400 clutch fan, so going to C box would allow you to use that as
well....

Confidence in what? ;-)

mkIII - Raking leaves and splitting firewood instead of flying this
beautiful Sunday at hauck's holler. Got an hour day before yesterday
though. 912ULS is honking. Climbing at 5400 and turning 5500 at WOT
straight and level. Will only fly 90 mph with the 8" Maule Tundra
Tailwheel. Will do 95 with a 6" solid Maule. Sure works better on the
ground though.

For what it's worth, Powefin's newer props are more heavily made. I still have
my F model that I'd bought to try on my FSII and its blades are a fair bit more
robust than the F I had on my trike. It was evident even with a heft test, the
newer blades are noticeably heavier, tho not by a lot.
The powerfin is the most efficient pusher you can buy. I could get 1800fpm sustained
climb on my trike with its F model 2 blade. The only other prop that could
come close was my tennessee woodie which gave about 1400 to 1500.
My F model 3 blade on the FSII did climb better than the warp drive set for the
same rpms, but it didn't do well in cruise which is why I went back to the warp
drive. The warp still gave the best overall performance....

I was able to do a field repair to keep flying that day, but afterward I
decided to get a new blade. It just didn't make good sense to me to risk the
aircraft for the cost of a single prop blade.

When did Powerfin go to a heavier blade? I didn't get my prop until January
of 2007.Lucien, I had a rice king and put the standard drive back in my C
box. Why do you like them?

Good move, as I've related before, some years ago I witnessed the bad crash
of a MKIII due to the failure of a repaired Powerfin prop.
