What is the proper way to mount the prop on a slow stick?The motor shaft seams to be oversize.Is the prop screwed on to the motor shaft?This is the prop that came with it.

What motor/gearbox do you have? What prop? You may need a collet adapter, and you may need to bore out the prop hub to suit.

If you have a stock 400 geared motor (black gear case) and they sent slow fly props in the box, you will have to ream them out or use a drill to make the prop hole larger. I think the shaft on the GWS gear box is a 4mm if I remember right.
Hope this is your question??????????

As Bob says.. if it is a 4mm threaded shaft, then you can drill out the prop to 4mm, and attach it directly with the nuts and washers provided.

It has a 4mm shaft.I'll drill it out .Thank you

A 5/32" drill is just a little smaller than 4mm (0.15625" compared to 0.15748") that should work if you don't have any metric drills.

And interference of 123/1,000,000ths of an inch will give you a nice fit.

Just get a 4mm prop saver easier to set up and it will save you money from broke props. I can tell you it will pay for itself the first bad landing.
