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

My understanding is that the GWS Slow Stick comes with a "prop adapter" (set screw of adapter can barely be seen in the left picture). Depending upon the prop source, you may need to ream or drill out the prop hole until it fits the adapter shaft.

To protect the prop from damage, many flyers use "prop savers" instead (in right picture shown without rubber band or o-ring). Again, the prop may need to be reamed or drilled. The prop saver holds the prop with a rubber band giving an elastic property to the mounting.

I'm sure you have solved the problem by now, but for others that may look to this thread for an answer....here it is.

I had the same problem. GWS just makes all their props with 3mm holes. You will just need to drill the hole a little larger for your use.

The Slow Stick 400 will require a 5/32" drill to make the hole the proper size. The drill will self center when you start the drill down since there is already a hole. Drill a couple while you are at it.

Have fun!

Thanks to everybody for the information.
