PropPastie is a new style spinner cover, designed to minimize snow, ice, and water from lying on your propeller hub and bearings and freezing inside your spinner. PropPastie fits all light aircraft.
The proper way to position a propeller in the winter is to have a blade vertical on the bottom to allow water to drain. However, this will allow water, snow and ice to sit on your propeller hub and bearings. This could have disastrous effects should any water leak into your propeller hub. Without PropPastie, blowing snow also could end up inside your spinner and cause a detrimental imbalance.
Use PropPastie to protect your controllable pitch propeller hub and bearings from water and ice. Use PropPastie to protect your engine and airframe from vibration caused by snow and ice in the spinner.
PropPastie is made in the USA with the highest quality UV-stabilized materials. It is designed to withstand all but the most extreme temperatures. PropPastie has remained in position in testing, in up to 51 mph. gusts. The material selected stiffens in cold temperatures. This in combination with Velcro holds PropPastie in place.
