Is anyone using a Kiev prop on a 912UL.  If so, what length, etc.  Does it 

perform better, worse, than say, WD constant speed?  Is it worth the price? 

Ted Cowan, Slingshot 912UL.  Oh yeah, is it really quieter?

I had a Kiev Hot prop on my MK-III Xtra with a Rotax 912-S.  It is a beautiful looking prop, but much to lightly made.  The blades, the hub, and even the spacer looked to fragile to last over time.  It always worried me, and I found myself checking it constantly.  What pushed me over the edge was when a local airline maintenance inspector that also works on experimental airplanes said " I don't see how that can last hundreds of hours "   I ordered and installed a Warp Drive prop soon after.



Installing he Warp drive was the best thing I could have done safety wise.  The warp drive stayed together when I ran my Lockwood Pressure Gage set through the prop while balancing the carbs at full power       The Kiev Prop would have most definitely come apart and over-sped the engine, having the Warp Drive saved me a BUNCH of money that day.    On a pusher, things do go through the prop, muffler parts, oil caps, you never know what, but it does happen.  The very strong Warp Drive prop is a huge safety advantage on a pusher.

Kiev prop.......... I have a 68" 3 blade on my FS II; it replaced a  WD.  Reason I changed is because the Warp got a small split in the end of  one blade & the slightly used Kiev was available for a real good  price.

  

 Kiev is better looking, I like the white front & the scimitar shape, it  is quieter on my plane {but I have about a 3" extension on it}, it's  lighter,  performance seems about the same as the Warp.  Price is  about the same.

  

 Robert Broadwell has a MkIIIC on floats & a Highlander, both with  912S at our field.  They both have Kiev's- 70" I think.  He especially  likes the toughness of the Kiev, as he has close to 1,000 water takeoffs w/ that  prop [float-plane props take a beating from the spray].

The Kiev has nickel leading edge plating, as does the Warp Drive, this makes it suitable for flying in Rain, Floats, where water would be hitting the leading edge.  Either prop would be fine on floats.   This does NOT make the Kiev a tough prop, to the contrary, the Kiev is very light and fragile.  For mounting on a pusher Kolb MK III, you need a very strong prop capable of staying together when a foreign object goes through it, not one that is ONLY resistant to water spray. 



Look at the picture below, putting 100 HP into that narrow aluminum prop spacer is not something I was comfortable with.  My Warp Drive prop has a much bigger mounting bolt pattern and much larger diameter spacer.  Both the Hub and Prop blades are extremely light, definitely not what I want considering the strong power pulses of the Rotax 912.  But if anyone wants a good, slightly used Kiev Prop for a Rotax 912, I have one for sale !!!  As much as I would like to sell this prop and get back some of the money I paid for it, I am not the type of person that would sell something that might get someone hurt in their Kolb just so that I can profit.  If anyone wants to buy this prop, they will get my honest opinion about and its potential hazards first.

What diameter is it and how much you want for it?

Oh, never mind. I see it doesn't have the right bolt pattern for my extension...

Ted emailed me a couple days ago about this prop, so I will give him first shot at it.  Given what he has been through, I think he need to try a new prop to see if it solves his problem.



So here is what I will do Ted, if you want the prop, I will sell it to you.  If it works and you are happy with it, great !  If it does not help your plane at all, and you are just as happy with your Warp Drive, send it back to me undamaged, and I will give you your money back minus the shipping.  Basically this lets you try the prop risk free, and we are all protected financially.



It is a nice and beautiful prop, I think you will like it.  Weather it will solve your problem or not is anyones guess, but this gives you a way to find out.  Its a 72 inch prop, I had been keeping it for a spare, it is a very nice prop with beautiful craftsmanship and black finish, it just worries me that its so light.   Let me know if this works for you
