PZ 9x6, slow fly style. 9x4.5 should be fine - same diameter, less pitch, should be slower. That's IF you are using stock motor.
Be aware that the numbers on a prop don't tell the whole story in amp draw. A SF prop of a certain size can pull a whole lot more amps than a thin electric of the same size or even larger.

I am about to change my damaged prop, which is the stock 9x6 supplied with the HZ SC. I have the stock motor and 3-cell Lipo. The guy in this video recommends something called a GWS 10x6 EP, which he claims gives longer flying times and other advantages. www.youtube.com/watch?v=cE0vv1i2jl8&feature=related (the bit about the prop starts at 3.00). Bearing in mind that I am still learning to fly, is it advisable to stick with the 9x6 or go for the one mentioned above? And will the guy in my LHS (in UK) understand what that prop size means - because I don't!

The store is in Chandler's Ford, near Southampton. The two guys in there know their stuff. I've just been there. They do have 10x6 prop but unfortunately its design is not compatible with the SC (it hasn't got the nut recess). I have been "flying" for nearly a year, but in truth it has been more crashing than flying, and long intervals while I haven't been able to get out with the plane. So I am pretty inexperienced. I would still be grateful for advice on whether I should change to the 10x6 described in my previous post.

I'm pretty sure those GWS 10x6 is a HD/DD one as sold at www.giantcod.co.uk although looking a minute ago they are listed as RD/Slow-fly. I've had quite a few from there and they were all HD/DD and work fine. An alternative which is definately what the guy is on about can be got here as well as a stack of other sizes. This is a bit more expensive than the big fish. Will you notice any difference? Probably not, but a darn sight cheaper than the rip-off HZ props.

GWS = Grand Wing Servo The only 10x6 (10 = diameter; 6 = pitch) they make is a HD (they call it EP). The problem with GWS is their naming stinks so badly that everyone doesn't use it and makes up their own common name which is not universal. HD = hyperdrive, often called DD = direct drive. GWS uses EP = electric power Essentially these are the skinny props with larger hubs for higher RPM and power applications. The equivalent prop for APC is the thin electric. An APCe of 10x5 is essentially identical to a GWS 10x6 HD for about 2x the cost. The SF of both brands have a small hub and a fatter kind of elongated figure 8-shape. The GWS-SF are pretty floppy and only suitable for VERY slow low power applications. GWS calls them RS = Reduction Series, designed for their low geared (low power) brushed motors. The APC-SF are much stouter and can handle a lot more power. Any SF prop of a particular size will draw a good deal more power than a similar sized HD/thin electric prop. Example. The HZ stock prop is a 9x6SF. I think the GWS 10x6 HD actually draws a bit less power, probably at the expense of a bit less performance. I would guess most new fliers would not even notice the difference, but will notice the cost difference. Do some research at HeadsUPRC. He does motor testing with various props to give you and idea of the power differences they make. His examples will have links to the props for you to look at. It's very informative, worth visiting just for that information. www.headsuprc.com/servlet/StoreFront

Very many thanks to you all for your very informative advice, especially flydiver for that comprehensive explanation.
From all the advice, on balance it seems that at my stage of the game I might as well stick with the stock 9x6 and upgrade when I am more proficient.
Again, many thanks to you all.

If you are expecting props to 'bolt right on' without hassle, well don't labor under that illusion too long. This is another part of the industry that has about as much standardization as jello sculpture. I've almost never found a prop that fit an adapter, even with the half dozen adapter rings they provide. It's annoying.

Geoff Geoff, they only have SF ones, not really suitable for the SC. As I mentioned previously, the Big Fish sell decent enough clones at a very competitive price (59p for a 10x6!).
