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.
