| Subject: | Whirlwind Propeller RV10 |
This is my first post. I have found theses pages incredibly valuable place to get
information and educate myself. Some of you serial posters (TIM) have been
extremely helpful without even knowing I exist.
I need to choose a propeller in the next few months. I have a Barrett Precision
540 with cold air induction, PCU governor, B&C light weight starter, alternator,
and standby alternator in my garrage. It produced 288hp on the dyno. I am
using Brian's (Showplanes) cowl because it fits the Barrett with cold air induction.
Brian told me I needed a 15 spinner with his cowl and I can see why. I
used the MATCO wheels/brakes kit they sell for the RV10 including their front
axle with Goodyear Flight Custom III tires and the butyl tubes.
I am thinking about using the RV10 propeller from Whirlwind and their 200/400 Rocket
spinner. It is very light and I would like to move the battery forward if
possible even if I have to buy a lithium/iron battery to keep the weight down.
I know the Whirlwind is expensive. I am willing to pay for it if it is a good
performer and it is reliable. I should probably look at the TBO and AD situation
for the current model. I just want to know if anyone has already had any
experience with it, good or bad. The Hartzel a lot of you chose is the only other
one I am considering, and yes I looked at the MT. Three bladed props are
a little smoother and have more ground clearance. They are likely just a little
slower and make getting the bottom cowl off more difficult.
Any thoughts about either of these choices would be appreciated, even if you a
pitching something I have not considered. I suspect there may be some issues that
I have not considered. I just don't know what they might be or where to look.

I have exactly your setup and went with the MT prop. Smooth as silk with the Barrett.
The great thing about the MT is NO time limit and hasn't had an AD yet.
It's also cheaper than the Hartzell three blade. Having spent a lot of time in
RV10s with two and three blade props, the three blade is FAR superior in smoothness
and climb rate. Maybe a "touch" slower but I'm NOT convinced that it is.
A BPE with any three prop is fantastic!

Danny,

I wonder what this is based on as Hartzell as well as MT have the 72
months or 2400 hrs as far as I know?

Robert,
As you have investigated the WW prop, I assume you have decided the 650 hour tear
down is worth the pain. I suggest you talk to current WW prop owners about
the logistics of shipping these props and such.
There is a plethora of data on RV-10 props and how they perform, and the standard
Hartzell BA 2 blade prop has not been surpassed for overall speed performance.
There is also the obvious huge price bump for the three blade options. In
short, is a reported smoother prop worth all the down side? All the weight
reduction efforts you have listed would not come close to making up the speed
hit.
But - to each his own. My point here is to make sure you have balanced your equations
for this selection.

| Subject: | BPA Engine Oil Quick Grain - PIREP |
Hi
I have A Barret Precision Engine that doesn't (or didn't) have an oil quick drain.
It used an AN10 Tee with a cap due to how oil system was setup.
For the past couple of years I have been talking with SAF-Air at KOSH hoping they
would design an adapter for use with one of their quick drain values.
A few days I received what I think is one of their first adapters. It connects
the AN10 male end of the TEE to a straight thread male drain with enough internal
clearance top all the drain to operate.
What I didn't expect, but really like is that the drain hose connection portion"
can be removed and replaced with a knurled cap with an O-Ring. That way if the
drain valve leaks / weeps the cap catches / stops it from being a problem.
There are pre-drilled holes for safety wire so the everything is and remains
secure.
Operating the drain is simplicity itself. Simply remove the cap and screw on the
hose connection. As the connection is tightened, it opens the drain vale and
oil comes out.
Attached are a couple of pix sowing the install. The first has the cap on. The
second shows the cap removed and the hose connection installed. No oil is coming
out (yet) as it is hasn 't been tightened.
It is not on their website yet so if you are interest you will call to call.
Cheers
Les

Well that's what the paper work from MT said. If you are flying part 135 then there
is a time limit for sure.

There is virtually NO speed difference against a Barrett engine with three blade
and a regular engine from Van's or where ever with a two blade. And they are
very much smoother and lighter than a metal two blade. I weighed them both.

Something isn't stock about your speed. You are 5 mph above Van's stated
max speed at light weight, and 15 above their stated 75% cruise speed at
light wt. I don't know whether your speed is a 3/4 course GPS speed, EFIS
calculated speed or something else.
Don't have precise charts with me at moment, but I think 25 sq is a bit
above 75%
