MINOR ASSEMBLY REQUIRED
Propeller guards come as one part. Remove the four propellers (remember which propeller coincides with each motor since the pitch of the propellers varies for control) and snap the guard onto the Estes Proto X. Replace the propellers accordingly and device is now protected against light and mild crashes.
This functional model has been tested and redesigned in order to provide the most effective protection for your valuable quadcopter. This design is as small as possible to keep the mass down, while assuring the guard is still functional and rigid.
