**** New GWS Propeller HD1260 ****

[RAY GWS]

Dear All,

GWS has a new size of Propeller: GW/HD1260 --- a new size to add onto GWS HD series.

http://www.gws.com.tw/english/product/propeller/propeller_hyper.htm

GWS HD Propellers are very excellent propellers. It was designed by GWS CEO Mr. Lin. The performance of HD series is better than APC (in the same spec or size). This one will be a good prop for GWS Formosa II flyers to use.



The other photo is the GWS EZ Connector. It comes with 5 EZ Connectors and the allen wrench. Using set screw to decrease the weight. Keep this good parts handy to make your life easier and with more time to fly.

Ray thanks for the info.

The APC prop your comparing to lists the RPM limt for saftys sake. For example a 12x10E prop APC can be spun to nearly 16K RPM.

Will GWS provide RPM limits to make sure there props are operated safely?

Thank You

Hi Tommy,

How are you doing? Still remember your nice car.

We tried those propeller and see how much thrust and current we can get.

GWS HD propellers can provide more thrust with less current draw (with same motor and power supplier).

As to the RPM limits, I will pass to RD for them to test. Thank you for your info.

GWS has many different type of propellers.

HD series is much stronger. It looks like GWS direct Drive Propellers but much stronger.

Some flyers may not know this. Welcome to check it out at GWS dealers.
