Choosing a propellor - advice please!

[Bullit]

Hi all.

Does anybody have any experience with the Warp Drive 72 inch 2 blade propeller? Available from Comet for just over R5K (http://cometaviationsupplies.co.za/inde ... ct_id=2113

I have A Rotax 503 DCDI and the choice of either a b- or a c-gearbox - have one of each. Together with that I also have a Pieter de Necker wood prop - 63x34 if I remember correctly. The prop has a small crack in the trailing edge, but I am sure it can be repaired - still have to confirm and get a price for that.

The engine/gearbox/prop will go on a Scout cart with Windlass wing, which I am busy rebuilding (She went back on her wheels this past weekend )

I need to choose between repairing the P Prop and use with b-box (because I have it and will likely cost me the least to get into the air, but will performance be OK?), get a Warp 2 blade to use with the c-box (because it is a really good price, but I cannot find any info on it's performance), or get a new NC or P Prop (proven, but expensive).

What would you do?

Hi,

I will defnitely go for the c-box with the NC prop. We have a scout flying in potties with a e-box and a NC prop and it flies extremely well.

It is expensive but worth the money.

The ratio of the e-box on Willie's scout is 3,47.

Hi Bullit!
We have two-bladed propellers are used very rarely.
All switched to three-bladed propellers.
They are always quieter and more comfortable to use.
For Rotax 503 with gear B 1 / 2.58, I recommend a three-bladed 1600 mm 63 ".
There is an option with straight blades and Sabre.
Sabre has certainly quieter and pull her up.
But it is more expensive - 540 €.
Straight blade - 450 €.
The maximum thrust of 140 kg (standard conditions).
In the case of third gear can apply a three-bladed propeller diameter of 1700 mm.
Link will reach 145 kg.
Only in the case of the gear 1 / 3.47 can be applied three-bladed propeller of 1750 mm 69 ".
Link to nearly 150 kg.
Two-bladed propellers are also possible, but thrust them below, and the noise is always higher.
But they are cheaper.
Two-blade carbon propeller diameter 1820 mm 72 "Sabre is 430 € and direct 390 €.
However, the prices mentioned - just before the end of this season.
Another feature: Propellers large diameter will deteriorate with increasing speed.
They are only good at the start.

Thanks Meglin

How much to ship to ZA?

And if anyone is interested - Contacted Warp Drive and they do not not recommend using this prop on a trike/503.

There is also Nigel Coats, NC composite props, in Johannesburg. Be aware of the import duties and shipping charges on imported aviation components.

Yes, indeed, delivery propeller in your country is 50 €.

Yes, 50 € is shipping to South Africa.

During this time, quite a lot of our propellers went to South Africa. I hope the owners are happy.
