question to the technical boys?
The aerrie we are currently flying has had the same prop on since purchace 2 blade woody.We were "told" to replace prop due to vibration.
To recon the prop is 50% cheaper but still costly than a new woody.I see some 503 have the 3-blade warps on.
My question is this?
1)Is it better to stick to 2 blade woody. "with b-box"
2)Go 3-blade warp prop?
3)Can old prop be rebalanced and is it worth it?

If we need to spend money,we'd like to do it wisely.
thanx

I understand woody's have better thrust but are more unbalanced. Composites run smoother.

Each have their pro's and con's

I trained on a Safari 582 with a 2 blade Piet de Necker prop, I think it had more oomph than my smooth 3 blade warp-drive.

But be CAREFUL, I had a gnarly vibration every 2400 RPM ( harmonic caused by the combination of a 4:1 gear ratio, 3 blade prop, and two stroke/2cylinder motor)

So changing to a 3 blade composite could cause you more heartache if your combination is odd.

I replaced my 4:1 with a 3.47:1 and Piet de N tuned the prop for me - she is a beauty now! (PS any one want a 4:1 gear for a 582?)

2-blade wood for sure....
Old prop can be re-balanced for next-to-nothing without any problems. Done it many times :D and completely refurbished for a little more...

DarkHelmet posted you some good advice on this one.. :D

THANX FOR THAT D.H AND DR
Also had some feedback on "keeping the woody" like my name i love wood.Some say you can do this balancing at home, if so can you assist through pm or give a few contacts in my area. Wood like to learn the finer detail on this issue
thanx

Sorry, can't help you with any contact persons in your area.
Just phone Pieter de Necker on 011 793-5235. He will refurbish and re-balance at the same time.
If you're monetary challenged (an "armgat" like me) phone Johan Maritz on 0828223179. He can balance it for you. Stays in Alberton, I think, but works out at Baragwanath airfield.

Hi Woody

I have a 2 blade Piet prop and a 3blade warp and I can tell you first hand that it just depens what you want. If I were you, I wood contact Piet as Duck sugested and get your wood redone. The Warp is smooth and quiet BUT there is a definate power LOSS.

Had a wooden Geo Killey prop on my old windlass which I took to Piet de N. He rebalanced and refurbished it including new stainless leading edges for next to nothing. Prop was like new again when I got it back. Would recomend his services anytime.

thanks all for the advice woody uhhh the prop will stay in commission
