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!

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.

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.

Nope that's news to me. Has a 2016 date on the SB. That wasn't in the paperwork I got with mine from three years ago. Some SB's are good and some are to cover their a*ses.
This looks like one of the latter. To each his own however! Thanks for the update. Danny

One other consideration for the MT is whether or not you are running a non-certified ignition system. MT does not warranty their propellers if the engine is using a non-certified ignition. I am guessing that is not an issue with Whirlwind, but is worth checking.

Kelly,

The plane has a stock engine and prop (other than injectors changed as needed to balance the cylinders), and still flying with these !#&$ mags as I wait for the six cylinder pMag.  I tried to keep the plane light (1659 pounds empty after a relatively heavy basecoat/clearcoat paint job).  I also spend a bunch of hours on rigging.  To be fair, the top speed run was done solo at 6500’ with half tanks and the engine ROP.  Airframe modifications include:
<![if !supportLists]>· <![endif]>James cowl and plenum
<![if !supportLists]>· <![endif]>James wheel pants
<![if !supportLists]>· <![endif]>Modified air box
<![if !supportLists]>· <![endif]>Extra shim under the HS forward spar (not really sure if this does much but the elevators seem to me more in trail with the shim)
<![if !supportLists]>· <![endif]>Not yet done is to put the damns back in front of #1 and #2 cylinders, but much shorter than what I started with

The plane was set up from the start for high efficiency LOP cruise.  The downside is the reduced cooling drag requires 125-130 kt climb speed to keep the jugs cool, so no pointing the nose up and hanging on the prop.  The attached screen shot is a typical cross country set up.

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.

So far, I don't recall any replies addressing the Whirlwind prop. I was disappointed when I went to the Whirlwind website and couldn't find any information on a prop for the IO-540, in fact nothing except for 4 cyl and radial engines.  While I'm sure the discussion of Hartzell 2 blade vs MT 3 blade is helpful, getting details about the Whirlwind would be better. I see that their standard RV-10 prop is an 80" 2 blade, and they also offer a 3 blade. I see the warranty is better on the 2 blade.

Carl,

Thanks for the detail. I can only guess that your cowl and wheel pants are part of the difference. I too am using mags, but the more stout Bendix 1200 series, which so far have been flawless. I am convinced that aerodynamic clean-up does a lot more for speed than adding power. I was guessing your top speed had to be somewhere near 6500-7500 ft. You have certainly bested the factory numbers.

Kelly,
 
The plane has a stock engine and prop (other than injectors changed as needed to balance the cylinders), and still flying with these !#&$ mags as I wait for the six cylinder pMag.  I tried to keep the plane light (1659 pounds empty after a relatively heavy basecoat/clearcoat paint job).  I also spend a bunch of hours on rigging.  To be fair, the top speed run was done solo at 6500’ with half tanks and the engine ROP.  Airframe modifications include:
·         James cowl and plenum
·         James wheel pants
·         Modified air box
·         Extra shim under the HS forward spar (not really sure if this does much but the elevators seem to me more in trail with the shim)
·         Not yet done is to put the damns back in front of #1 and #2 cylinders, but much shorter than what I started with
 
The plane was set up from the start for high efficiency LOP cruise.  The downside is the reduced cooling drag requires 125-130 kt climb speed to keep the jugs cool, so no pointing the nose up and hanging on the prop.  The attached screen shot is a typical cross country set up.
 
Carl

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%

Yep - add power and the fuel to get it and you go faster.

Yes, I found it....curious why there are different sites for ground adjustable series and constant speed.
