O-ring Propsavers for 24gm motor - 3mm shaft

We have three different O-ring Propeller Mount "propsavers" to fit 3mm motor shafts. Select the one that's right for you!

A) The "lightweight" propsaver comes with one #13 O-ring and is relatively lightweight at only 1.7gms. This is appropriate for use with our 1300KV "Blue Wonder" motors.

B) The "Better" propsaver is made from black phenolic plastic, appropriate for high-speed motors such as our 1700KV or 3000KV "OMG" motor and 2-bladed APC 4" to 6" props. Includes THREE heavy-duty O-rings. Weight (adapter only): 3 gms.  

C) The "Heavy Duty" propsaver is metal, NO O-ring comes with it. This is appropriate for larger motors and propellers.  It is 3.5gms.

These all fit 3mm motor shaft - use to secure the prop to your motor and it will help prevent your prop from breaking if it contacts the ground. Set up for a regular 2-blade propeller but can also be used with a 3-bladed prop (put the O-ring around one prop blade.)  Propsavers cannot be used with our spinners, the spinners require prop adapters.  Here's what the -B- "better" propsaver looks like mounted on a 3-blade propeller:

  

We do have #13 O-rings available separately. O-rings must be changed out on a regular basis as they quickly degrade and crack when outside.   This is a bit of a hassle, but of course the benefit is that you won't break your propellers each time you fly!
