Prop saver for GWS IPS systems

I have just put together a short article on how to make a prop save for the GWS motor systems. It is posted at our clubs web site under the articles section.'

Here is a picture:

Looks good but you should bottom the severo horn out on the shaft then cut off the remaining threads. It will help limit bending of the shaft.

Hi GHarvey, nice web site and good article.

Check out this thread by Tim_J-Rome from December 2001:

Original ideas are hard to come by...but it's still a good one. Wish I could get ahold of some braces rubber bands, but the O-Rings work well.

I swiped a bunch of little elastics that my daughter uses to tie her hair back. You might need more than one, but it works well. I'm still on my original 10x4.7.

Yep, Like GHarvey said, good ideas are hard to come by.

And the really good ideas get spread around.

I saw that GWS saver as well. Too bad they show it with the shaft still extended through the prop. That will keep it from being saved.

you are right
GWS really likes the users to use the "safety spinner"

Why would you want a long prop shaft?

I have kept my shafts full length up till now in case I want to use the motor on a different plane and run a standard prop config.

The only problem I have had so far was a 40' straight down dive when a hornet distracted me while windy flying. The impact divided the spur gear in 1/2 and fragmented the gearbox. Maybe ... just maybe I would have had less damage with a shorter shaft.

I find the spinners make great replacement caps for my CA bottles. They fit well, don't seem to stick and have a larger area to grab on to.

If you don't have an spare servo arm, a piece of a popsicle stick or 1/16-inch plywood will work just as well:

Secure the piece of wood with the original GWS nuts and washers. Unlike the example above, you'll want to shorten the shaft to reduce the chances of bending it in a severe impact.
