Electric motors require lighter props generally than glow motors; they do not need the flywheel effect of a heavy prop to sustain ingnition and can develop more revs with light blades. The growing popularity of sport, cabin, aerobatic and scale electric aircraft has created a demand for suitable fixed blade props. The two most popular brands are Graupner and APC.

I have given the size of the bore in each prop as this has been an issue with some fliers.

APC provide a stepped hub. The hole in the front is nominally 6.5mm, but I have noticed that the size varies slightly, and even APC themselves say that this is not a precision hole. The rear side of the hub has a 9mm hole which is precison made, and this creates a step in the bore of the prop. A range of collets is supplied with each propeller to fit in this rear stepped hole to adjust the bore in a range of sizes right down to 3mm. So, you can either add the required collet, or bore out the hole to 9mm.

Fixed blade props need to be balanced, just like the folding variety. Click here to read an article on balancing props; the technique is the same even though the article refers to folding props.

Why are the prices all over the place? because it depends when I purchased the stock. Recent additions have suffered badly from the depressed eschange rate - but I am maintaining a supply of these props to keep you flying - despite the vagaries of the dollar!
