Description
When you use a folding propeller in pusher configuration, you must stop the blades from folding beyond 90 degrees. If the blades fold too far, when you re-start your motor, the excessively folded blade will not pop out and work – in fact, it will cause vibration that could damage your model.
You can make up a stopper yourself, but aero-naut provide convenient prop stoppers made out of fibreglass. They need to be trimmed to the correct length for your centrepiece, but you can see the idea in the accompanying photographs.
Incidentally, you can see that you need to fit your blades with the writing facing forwards in this application.
Two-blade Fibreglass Prop Stopper – $7.50
Three-blade Fibreglass Prop Stopper – $5.95
