1/2A props
« on: July 14, 2012, 07:21:33 AM »
Do any of you fellows know if there has been any progress on getting some of the glass 1/2A props made? Me and a bunch of FF guys are looking for the 5x2.75 units that were green.

Yuvenko doesn't have 'em in stock, according to the site.
A guy at the Houston meet maybe thought there was a plan to get them made.

Those Eliminator sizes aren't whay we need.

I know of about 60 props that guys want.

Eliminator Props (c3) is 5x2,3/4 .It is like the GRS Moldels green prop but it is carbon fiber.Its a good prop but you have to do the finish work and balance.

I just tried some Eliminator props from Steve Wilks. I liked them and as Al said you have to do a little finish work and sanding.

            Chris, in a recent e-mail to Steve he offers some of these props in glass as well. Either way your dealing with a fragile item. Each having it's own advantages over each other , it becomes personal choice and useage. Just for the record, he said he could make some of these props in glass. ken

Hi Ken,

Yeah, those carbon props don't take well to a ground pounding and neither do my F2D fiberglass props!

For 1/2A combat there were some guys at the Nats using Tornado white nylon props. Those held up really well on a vertical landing.

                Chris, I think this is incredibly important, the 1/2 A community needs props. It's been mentioned in a prior Flying Models article about the unavailability of engines. I find it harder to find props than engines. Hobby Club is carrying engines and glass props . I can't justify spending $8 per prop plus shipping. APC's are ok but some are quite expensive and mild grass landings break them. We need these props. Tornado's were terrific props but obsolete now. For those that have them, they're stealing all the fun. The 1/2 A community needs to bark louder. Ken

Here's the thing----the green glass props were 4 clams ready to fly. 8 bucks and i need to work on it isn't what we're looking for.
I know enough FF guys to unload about 60-70 props if we can get them.

                             I wonder what ever happened to the molds and machinery for the Tornado line of props. Hobby club stocks the Russian greenie. It costs $7.95 and a few more dollars to ship to me. This certainly makes the prop out of touch with reality. Although I feel that I could satisfactorily use this prop now without breaking, it certainly happens frequently in a match. The APC 4.6 x 3 is looking better and better. The rubber ducky is a good old stand by. The wide blades have proved to be problematic on some of my engines unless the prop is cut down to the size of spaghetti bowties. Ken

'Tornado's were terrific props but obsolete now. For those that have them, they're stealing all the fun.'

I've still got a dozen or two of them.  Kind of funny though......when we flew a few weeks ago Doss picked up one of the planes by the prop and the prop promptly snapped in two.

So I guess with age they have become brittle and my stash of Tornado's might not be usable.

If they are nylon, put them in a pan of boiling water. H^^

Hey Dan,

You might have some luck putting together an order with the Northwest guys (check www.flyinglines.org).
Tom Siegler might have some, too. Or maybe we could talk Doug Galbreath into stocking some.

-Chris

ps. Doc's suggestion of boiling the nylon props is a good one, too. Probably mandatory if you use nylon props.

            That certainly sounds like a great idea Chris. The next problem is getting the cost down. I know Yuvenko sells props for a fair price. I just don't know about the remaining costs such as shipping and how that affects the total cost. The bigger problem is in regards to how many you need to purchase. Think about it , 200-400 needed for a purchase. It seems like there aren't that many of us flying 1/2 A combat. Even if we bought three times  the amount we needed. I never had a Tornado white fracture on me personally. I had Top Flite props do it though. My dad always suggested boiling and I passed on the idea. My son has one good eye to begin with and I certainly don't need to take a chance with a prop that decides to depart. The black Tornado props do break, but they had a very good blade to them making them quite effective. Ken

try www.coxengines.ca   The have the black Cox 5/3 prop for $2.49.  Cut down to 4.25 or so seems to work well on both the hi-zoot engines and the Norvel .061's.  They are better and stronger than the Tornado props, but not quite as fast as a good glass prop.

Phil, I run the black Cox 5x3 on my WenMac. A solid 14k. On a Jasco streak, Nats winner.

It ain't the answer for the VA on my regular 1/2A. That's where the green glass props are needed.
There is some discussion relative to getting some made.

Depending on which engine you're running the APC 5.5x2.5 or 5.5x2 will work pretty well. If you trim below 5" on any of the props you will lose a lot of speed in manuevers towing a streamer. The rubber props are nice from the "no Break standpoint" but when trimmed small enough to prduce good airspeed they are woefully lacking in disc area to pull the plane thru manuevers. Most of the freeflighters out here run APC's in one of the two sizes above on Piccos, Cyclons, Fora's etc (.049 or .061). I have a "one off" Russian carbon prop that is unbelieveably good but is now un-obtanium and cost $12.00 ~^ when it was available. If you're running a good TD the black Cox 3p (the ones Dale used to sell, they just have 3P on them, no dia. )works pretty well. You can duplicate it by cutting a black cox 6-3 down to 5", and No it is not the same as a Cox 5-3 8)

Bob, the green prop is a 5x2.75. remember, I'm flyin' combat but FF gas.
Getting some green ones made is in the works.
7x2 is way too big for the VA 049.

I think I've seen a box of your props in Joe Clawson's hands. Lots of sizes there.

Don, the engine will spin the 5.5x2 but it does better with the green prop. More turns, better acceleration and thus height.
The difference between a Cyclon 048 and 061 in re power is significant.
The 5,5x2 isn't a real good choice for the Cyclon 049, despite the fact that a LOT of guys run it.

Dan;
   I was just pointing out that the APC's are available, fairly cheap, and work better for combat or free flight than the rubber duckys if you can't get the glass or carbon ones, or, are too cheap to spend the bucks. Unfortunately, almost no-one flys much 1/2A out here anymore. I miss the days of TD's on 35' lines with nylon props. We used to fly Round Robin 1/2A matches all day long at least one day a week. I used to build TD's for most of the local guys.  If you want to be serious about 1/2A nowdays, it's almost the same expense as F2D ~^If you want a state of the art engine $200-$300, state of the art prop $5-$8, airplane=small clone of F2D $35-$40 if you buy in bulk. I have a couple and they do rip and are fun to fly but I just cant motivated to compete anymore, and miss the creativity. 8)

If you've got the Cyclon, try a APC 4.6x3. A better choice than the 5.5x2.
I have a supply of the greenies. A bunch of FF guys are wanting them. That was the original purpose in starting this thread.

Hey Bob, watch for a P.M. with info.
The 5 1/4 x 3 is a great prop but we don't think it should be turning 31K in the nylon form.
I do know a guy who only ever ran a Grish 5x3 nylon on his Shuriken.

Guys,
I know the very green combat prop you are looking for. Buzz Wilson has just put in an order and somewhere around 100+ have come available due to one of the people backing out at the last min.
Send Buzz an email and tell him Kenny-b sent you.

Hello every body.

Aerohobby.CA  is the place to buy the 1/2A green prop, they have 15 in stock right now. But they will get 500 next week.
