All these adapters are allow the prop to easily dislodge in an accident. They are held in place by O-Rings. These are not reccomended for high RPM applications. Essentially, if the expected top speed is over 40mph, you should consider using a Collet or Set Screw type adapter. Use your own judgement and good reason here. The best way to save props is to understand they make very poor landing gear. ;-)

This unit has a blind hole for the motor shaft. The front of the adapter becomes the front of the shaft. A 1.4mm nub centers your prop. Made for props designed to press onto 1.5mm shafts. Perfect to get your GWS 3-2 or 3-3 prop mounted with a saver on your brushless motor. We suggest our small o-rings above for use with this saver.
