I keep hearing about the Pro Zinger wood props, particularly from Tailtwister. I only ever see the Zinger props in the LHS. I take it they are different and where can one get the Pro Zingers? As far as which one for each engine I'm guessing if you use a 14-4w it would be a 13-6 Pro Zinger, 16-4w would be a 15-6 Pro Zinger?

The pro Zinger props have a different shaped tip than the regular zingers. Much more efficient and seem to spin up quicker. The pro Zinger 18-6 for example is one of the best prop options for the OS 160.

Thanks Mike but where can I buy them? I guess I could ask the LHS to order some. Boy some days it is a pain in the butt being Canadian. We play good hockey though!

Tower has them.

Hi,

Horizon Hobby also sells Pro-Zinger's. I needed a 22 X 6 and my local MAJOR hobby store (Grave's in Orlando) didn't have any. I went to my other local very small hobby store and made a deal with him. The props come 2 per bag and are ordered by the bag. I really only wanted to try one prop and he didn't want to be stuck with an extra. So I bought one from him at retail and paid him his wholesale cost for the other. We both won! He made some money and I got a spare for cheap!

By the way, I moved and really miss Grave's. If you've never been, the place is amazing. No place like it anywhere in the US. Easily 300+ airplanes hanging from the ceiling. Probably 30 -40 assembled helicopters, hundreds of kits, hundreds of batteries, hundreds of radios systems (literally), and a massive amount of general stock. Kinda like Tower and Horizon catalogs pooled together, but no shipping. The major trick to the place is getting through the front door and past the checkout counter. Much improved from years back, though. If you are ever in central FL, definitely worth a side trip.

My LHS does not stock them, but can get them for me in a couple of days. I guess they come through Great Planes, as delivery is pretty fast.

I like the APC "W" series props, as they pull like nothing else, within a reasonable price range. Last season, one of the Bros was swearing up and down that the Pro Zingers were just as good as APC, and I pretty much ignored him. This season, I decided to give it a shot. My first try was on a Saito 72. I took off the APC 14x4W, and put on the PZ 14x4. I really could not tell the difference in pull out from a hover. I guess what ever it lost in actual pull, it gained back in transition time. Next came the Saito 82 with a 15x4 PZ, and it pulls like crazy on a 5+ pounder.

The last one for me to try will be a 15x6 PZ (they don't show a 16x4) in place of a 16x4 W APC. I expect to be able to notice the loss of an inch in diameter, but hope to like it as well, as my Saito 100 struggles a bit with the big ole' 16 incher out there, even on 30% nitro.

And no, I do not work or fly for Zinger in any capacity...[8D]

PS... Love the avatar Basement Troll!!!

Sounds like a winner to me. I know the 18x6 PZ is awesome on a Saito 180. The APC 18x6 is such a monstrossity, I refuse to put it on my plane.

If the 14x4 PZ is equal in pullout to an APC 14x4W, it's Lighter, AND cheaper, then there is no reason to ever get that APC prop anymore, unless you need nose weight.

The Zinger 14x4 regulars are still cheaper than the PZ version, so it pays for me to buy those instead by the dozen for my 4D.

I wonder if the average PZ prop is heavier than its non PZ size? They always look darker to me. I wonder if they use heavier maple? Maybe a different wood?

The weight was also a key factor in changing my mind. I had expected the lighter prop to spin up better, and then I had a plane that needed the CG just a hair further back. I could add like 1/2 ounce of lead to the tail, or go to a wooden prop. It didn't take long for me to decide to try the PZ then. In the end, the CG shift amounted to almost nothing, but the props performance opened my eyes a bit.

Hi Doug. It's funny you mentioned Graves as was there a week ago when I was in vacation. You are right it was amazing. Are those planes on consignment or do they just buy and sell used planes? I bought some servos and a couple of trinkets but, I flew to Orlando so I couldn't look at anything big. Great place!

The Pro Zinger 14x4 has worked very well in my Jett 76L powered Burrito. There is a significant weight difference between the two props. Here are the results from my digital scale:

Zinger Pro 14x4 = 33 grams (~ 1 1/8 oz)
APC 14x4w = 59 grams (~ 2 1/8 oz)

So, I measure around 1oz difference between the two props. One other observation, the APC hub is smaller so it appears that the weight increase is distributed in the blades. That is important because as the mass moves toward the tips, the spool up will take longer (if I remember physics... it's something to do with the moment of inertia). This link has good (technical) prop info.. check out the summary findings at the end of the article. http://www.geocities.com/CapeCanaver...es/GYROWEB.htm

Don,

Graves owns everything outright in that store! Has to be millions in inventory. You should see the store room. Speaking of props, he has a HUGE selection. He probably has 300+ REVERSE pitch props! Should you ever want one.
