Posted: Fri Aug 25, 2006 3:34 pm Post subject: Propellers - IVO or Warp

Hi guys,

  

 Getting on with my Mark 3 Xtra project with Flaps/Alirons and considering a  Rotax 912 ULS 100 HP and Prop.

 Would like to get your input on which Prop to use. Planning on a 70", three  blade but need to make a decision on brand/model. Price for me is a serious  consideration and it would be very nice to have ease of adjustment. Without your  experience I'm sure there are many things I haven't considered.

  

 Ivo has two suitable units. (1) Their Ultralite (Light) for up to 100HP (2)  Their Ultralite (Medium) for 100HP and higher. They also have the Magnum for  more powerful engines and higher speeds.

  

 Warp of course has the Warp.

  

 I understand the Warp is tougher and the Ivo much easier to adjust.

 The Ivo light prop is less expensive and the Ivo Medium or Warp about the  same price.

 What about maintenance? Also is the 2.5" spacer sufficient or will I need  the 4" spacer?

  

 I live on Johns Island, SC just outside of Charleston. (lowcountry) about  sea level.

 Density Altitude around 1200' - 2000' during the summer months and am a  fair weather flyer. Is there any other type in a light aircraft like ours?

  

 Thanks -- John Ratcliffe

I think you get better performance out of a two blade prop than with a 

three blade.

John,

 Between the two, I would go with the Warp.

 You might also consider the Powerfin, I have an F model  68" Powerfin on my Mk-3 and it is super easy to adjust and performs well.   However I do not have the high hours on it that others have with the Warp  Drive.  The Warp is surely the most well proven prop for  pushers.

 My $.02............I like a Warp Drive prop because it's the toughest prop you can buy.  It's also real heavy.  So heavy that, in some configurations, it's out of spec. for your gearbox.

  

 Check out the Kiev or Hot prop [same thing].  It's much lighter [you can use an extension no problem] , more efficient, smoother, quieter, prettier,  & tough.  We have one on a MkIII float plane with over 800 water landings & it almost looks like new.  I also have one on my FSII.

  

 Costs about the same as a Warp.

Just to muddy the waters a bit more -

Tried a three blade Kiev Hot Prop on the FSII with 582 and it did not 

perform as well as an Ivo 68" two blade. And it was noisier.



Today I delivered my old J-6 Karatoo to the grass strip where the new 

owner will be keeping it, I had always flown it with a 66" two blade 

Warp Drive, but after it's "incident" a while back, it got a 68" two 

blade Powerfin stuck on it instead. It is now about ten mph slower than 

it was with the Warp Drive. Perhaps it would still be as fast if it was 

a 66" prop instead? Don't know.



IMO, a Warp is extremely efficient, and almost indestructible. An Ivo is 

equally efficient, fragile compared to the Warp, and (because of it's 

flexibility) runs a lot smoother, much less vibration. Those would be my 

first choices for a prop. And IMO, a two blade is more efficient than a 

three blade.

Richard:



Was wondering how an IVO could "run a lot smoother, much less 

vibration" than a Warp Drive??



After 2,400 hours flying in front of a Warp Drive Prop, I have yet to 

find any one of the several I have owned to show any signs of 

"vibration".



Quite possibly, the Warp you were flying had a problem or was not 

adjusted in pitch, equal in all blades.



Or maybe it is a characteristic of a two blade Warp.  I do not know. 

Have never flown a two blade Warp on my airplane, or any other that I 

can recollect at this time.



For the record, I have never had to balance a Warp since day one, 

which was September 1993.  My Warp Drive Props are not babied.  They 

get to experience flight in many different environments, many of them 

quite harsh.  I just took off my last Warp Drive 3 blade prop which 

was installed in June 2004, just prior to my departure for Point 

Barrow, Alaska.  This prop came home with dings from rocks, sand, and 

gravel, bathed in a lot of rain.  My last flight with this prop and 

the engine that pushed me to Point Barrow twice, was just as smooth as 

it was when first installed.



In fact, I do not know of anyone who has ever had to balance a Warp 

Drive, even after minor repair from stuff that falls off the airplane 

or stuff that is thrown into the prop by the tires.



BTW:  Warp Drive has a life time guarantee of satisfaction for their 

product.  If for any reason you want to send it back and get your 

money, they are happy to oblige.  Most folks don't want to give their 

Warp Drive away.  They are tough, efficient, and will get you there 

and back home safely.

John, I just purchased an IVO 66" two blade prop for my Firestar. Are you saying that THere may be a need or a time when I would need to balance it? I thought because of the factory weigh-in and match as well as the torque arm warping of the blade what took place with one side took place with both sides.

Not being an engineer, couldn't tell you why it is smoother. It is not 

that the prop vibrates, or was imbalanced, or anything of that nature, 

but having flown with both Ivo and Warp props, the engine/gearbox/prop 

combination with an Ivo gives a distinct impression of being smoother. I 

suspect the flexibility of the Ivo absorbs various harmonics, 

engine/gearbox vibrations, etc., whereas the stiffness of the Warp does 

not, but that is just a guess.



All of us on the list are aware you are a confirmed Warp advocate, and 

you have good reason to be, but in my limited experience (having flown 

only about 1,000 hours with only 4 Warp Drive props, three of them two 

blades, and one of them a three blade - and having owned only 5 Ivo's, 

two of them three blades and three of them two blades) an Ivo gives me a 

distinct impression of providing a smoother flying experience.

Ralph:



No, Sir!



I said I never had to balance a Warp Drive Prop.



I have flown IVO Props quite a bit on Kolb Factory airplanes over the 

years.  When the silver tape was applied correctly, and it was a new 

prop, was smooth as can be.  However, when the silver tape would start 

to release, just a little, that little prop would wear you out.



With the Warp Drive, I like the idea of setting the prop up, then 

flying 400 or 500 or more hours without touching it.  No need to. 

Once it is adjusted to the airplane and the engine, there isn't 

anything left to do.  The Warp I pulled off my airplane is still 

adjusted exactly like it was in June 2004, when I installed and 

adjusted it.



Yes, I am a Warp Drive kinda guy.  In addition, you might call me a 

Kolb kinda guy, a Rotax 912ULS kinda guy, MATCO wheels and brakes 

kinda guy, among a few other items of equipment I have used for a long 

time with a great deal of success, e.g., reliability.



Take care,

And John, Brother Kolber, 



I appreciate that you didn't take my question as an attack upon your person. I have always liked the careful way you word things, and have learned a bit of tact from that way. Both of us having Military backgrounds and "older" men, I would think myself as a low rank and you as an officer of merit would butt heads. Yet we don't. I am glad for that maturity in both of us. I rely heavily upon you're as well as others wisdom on this site. And guys, lets face it, We aren't playing with stuff that accepts a lot of "dumb" anywhere in it's make-up. Anytime we offer advise, it should be the best we can give because there as a great deal of â€œlurkersâ€ out there that will literally go out â€œon your wordâ€ and do, because you said it worked!



I am always amazed the differing results each individual seems to attain from "much-like" planes, albeit the build aspect. There are "hammer" mechanics as well as detailers that are so meticulous that appearance is almost everything, not discounting anyone's applications. I tend to be more the kind of guy that if a pound of steel will do the job, lets make it out of two pounds and be better. I once baked Lasagna in the oven. The box said 350 degrees for forty five minutes. I did it at 700 degrees in 23 minuets. It wasn't there when I went to get it! I really enjoy this site for the tremendous detail everyone offers, as well as the â€œcivilityâ€ of the writers.



I guess that when someone has applied the time tested ways to something, there is where one should look first for â€œwaysâ€. The more I fly, the greater the appreciation grows in me for the value of the trials and tribulations of the many of you that do some serious , distance flying, while I hang so close to the nest.

John / Gang,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

   

  Interesting comments about the IVO prop and leading edge tape. The IVO on my Firestar was a "factory installed option" so to speak. Meaning, it came with the engine/airplane when built by Bryan M (great job by the way, Bryan knows how to build a Kolb!). Anyway (my point) is to say that this plane with only about 6 hours of time on the engine, the leading edge tape is separating from the prop. Granted, this plane has set dormant for several years inside an enclosed trailer which may be the cause for this issue since it gets REALLY hot in there.

   

  I have had several observers notice this, and sternly advise to replace the tape before taking her up (only test flown after build, I am still in training). For now, the few hours of taxi work I have done, I have left it as is. But will replace it before first flight. It might just be me, but I think I hear a noticeable change in sound when I run the engine right after pressing that tape down. But it always lifts back up after a while.

   

  Strike one against this 2 blade IVO.

   

  Another problem I have is that this 2-blade prop rubs against the aileron tubes when the plane is folded. Seems that the prop  extension that is used, with the thrust angle, causes this. I asked a fellow flyer why the extension, and his thoughts were that to keep as much engine mass forward as possible, it was necessary for the extension to clear the back of the cage. He thought it was regular practice from Kolb (as they tend to be tail heavy?). Sounded reasonable to me, and I am happy to have it, except it is wearing out my aileron tubes! I have given serious thought to a 3-blade prop for that reason alone.

   

  Strike 2 against this 2 blade IVO.

   

  I don’t know if I want to wait for strike 3, so I will just ask instead…

   

  What 3 blade adjustable prop is best on a Firestar 2, and which would you men suggest? I would expect differing opinions, and that’s a good thing. This list is all about sharing of ideas, and were it not for that, all we would need would be a single “here’s how to do it” manual. What makes an idea worthy is when you have some experience to justify the opinion.

   

  There you have it, rant over. I hope you guys are all having a great weekend! I know I have, Saturday Steven Green flew in and allowed me my first few moments aloft in a Kolb (his Mk3)… how sweet it is! Thanks Steven!

Ivo used to use a really thick metal tape, but no more. The metal tape 

that comes on them now is wimpy. Replace it with Powerfin tape, they use 

a heavy thick vinyl, sticks great, price is right. Don't know how it 

reacts to heat. Probably not too well. Their phone # is on their web page.

Concerning prop extensions, the air coming off the wing surfaces creates 

a noise when it interfaces with the prop, and the further away from the 

wing you can get the prop, the quieter it will be. If you have ever 

listened to a Varieze when it flies over, they are a worst case example 

of wing/prop interference noise. A two blade prop on a Kolb with a 2 

stroke makes a lower-pitched growley sound, a three blade sounds like a 

typical 2 stroke ultralight.

Hi Guys,

  

 First I would like to thank everyone for their input. Without everyone's  help, I wonder if building would be as much fun, buying is much easier.

  

 Conclusions reached so far:

  

 1. Warp is tougher and easier to repair,  but heavier. 

     A. Not being foam filled would make them tougher, easier   to repair and heavier.

     B. Is everyone using the nickel leading edge? This would  impact all three advantages.

  

 2. Ivo is considered by some to be smoother, unless  the leading edge tape starts coming loose. 

    A. Without the nickel leading edge, Both brands would have  leading edge tape.

    B. With less then 100HP engine the light Ivo would be used,  whereas with the 100HP engine a medium Ivo is recommended. 

        Would the added stiffness  and additional weight of the medium make it less smooth?

    C. Smoothness suggests less vibration, if ultralites can be  considered quiet in any form, how would you quantify the difference? 

        (On a scale of 1-10) For smoothness?  For Quietness?

  

 3. An additional consideration in my case. With a 2 blade prop I can move  the plane into my air conditioned garage without modification to the door.

     A 2-blade prop is considered more  efficient and less expensive ???  

    Would appreciate a comparison between a 2-blade Ivo and Warp  for smoothness and quietness and between a 2-blade/3-blade prop, on a scale  of 1-10. 

  

 4. Current prices:

  

    Ivo 2 blade - $700

    Ivo 3 blade - $890 (Medium)

  

   Warp 2 blade - $495 (without nickel edge)

   Warp 3 blade - $685 (without nickel edge)

   Don't know what tapered tips cost. Didn't see any reference to  tapered tips on there site.

  

 So many questions. If money wasn't a consideration, why not just pick one  and move on. Maybe an Ivo 3-blade. Can be converted to a 2-blade for a trial and  if I like it, would have a spare blade. More expensive though.

  

 Again thanks for the help. Looking forward to all replies.

John, Please put down the drup pipe! (Joke, just a joke. Actually put down the bottle of Jim Beam). The IVO Ultralight 2 blade prop is $ 400 not $ 700. Unless you are equiping your plane with a 100 H.P. or greater engine, the ultralight prop should suffice according to the IVO web site. I just purchased a IVO 66" two blade prop to replace my old wooden prop and was told at any time I could add a third (see single piece purchase) at any time. The weight and mfg date are on the hub end of the prop. They are a very consious bunch of people and the quality is as good as any. 



Has anyone complained to IVO about the tape? They have a "tape replacement" video on their web site if it is a problem. Did they offer to relpace tape to anyone that had some of the tape come loose? If not, shame on them, the liabilities connected with that could come back and bite them. Plus, the PR would be very damaging to their growth and service value.

Gentlemen and ladies,



I am replying via the forum option, for some reason, I still get all the old email messages (my preference), but cannot respond to them! MATT D, What is up with that??



Anyways.....



I contacted IVO via email to tell them about the prop tape separation concern I was having. Since there is only 6 hours on the prop I thought they would be interested to know.



All I received back, was a message that I could buy new tape for 4 or 5 bucks plus shipping. Oh, and that they will accept a Credit Card with the 3 digit verification code on the back.



Well, I am glad they have a replacement tape, and itâ€™s available for a good price. But as for customer service, as in asking me about my prop to see why the tape would fail after only 6 hours, they did not score so well.



I will try again to contact them to further explain my concern.



I have to say, their prop at the very low end of RPM (1700/1800) has a really hard "thwap thwap thwap" sound (reminds me of a great scene, the movie "Mystery Alaska", if you get the reference your grinning, if not, go rent the movie!)... but when it kicks over the 2k range, she humms like a humming bird that wants to sing... and at full throttle she roars like a lion and WANTS to be airborne  NOW!!!



My point, I like the prop, and think it has great merit, but except for the tape separation thing, I would not complain.



Done whining... Except for the issue of not able to reply to the old email list!

Last year I purchased a new IVO 3 blade it did have less vibration but it preforms much better as a 2 blade on a 447 Rotax anyway  and I recently set up a warp and the IVO is much easier to adjuts but I think the warp would be much Stronger if you plan on running parts through it

I'm curious as to why you seem to be restricting your prop search to 

Warp and IVO. Maybe you've already narrowed down your search to these 

two companies. If not, there are other very good props available 

including PowerFin and GSC. Several Kolbers have had good experience 

with the PowerFin and I had very good experience with a GSC on my 

Titan. My GSC had Maple blades with an extremely hard leading edge 

insert that never ever showed any nicks operating from all kinds of 

nasty fields. I had a two-blade IVO on my early Firestar because that 

is what it had on it when I bought the airplane. No complaints.

I bought a new Ivo recently from CPS . The leading edge tape was very  

unsatisfactory  and I removed it after only a few hrs. I am running  

it without any leading edge protection for the moment. I received  

replacement edges with the prop but they are the same junk as what  

was on originally. It would be a wast of time to install them.



I have had satisfactory experiences with Ivo props in the past but  

with their current quality control I can no longer recommend them. I  

recommend Powerfin  for anything running a B box gear reduction.

I bought a new Ivo recently from CPS .    The leading edge tape was very  

unsatisfactory  and I removed it    after only a few hrs. I am running  

it without any leading edge    protection for the moment. I received  

replacement edges with the    prop but they are the same junk as what  

was on originally. It would    be a wast of time to install them.



I have had satisfactory experiences    with Ivo props in the past but  

with their current quality control I    can no longer recommend them. I  

recommend Powerfin  for    anything running a B box gear reduction.



	


 

 Eugene,

 The Firefly I bought from Duane came with a 2 blade IVO. The tape leading  edge was holding up OK for the first few hours of Seaplane use. After I dinged  it up with a loose bolt I called IVO for replacement tape. That was 2 years ago.  The replacement tape was much thinner and failed in about 2 hours. I asked them  why they went to a thinner tape and they said that the original vender no longer  had the thicker tape. After a few hours on the Internet I found a tape supplier  with a thicker tape. They sent me a sample roll. I also found that they had  supplied tape to IVO but IVO no longer bought from them. I never tried the tape  because shortly after that I received the Kiev prop. I suspect that they are  still using the thin stuff. I don't know how either tape holds up with  normal use, but with a lot of water exposure both fail quickly. If you want to  try some of the sample roll, let me know.

 I think IVO makes a good product, It just is not suitable for  Seaplanes.
