PropPastie is made in the USA
with the highest quality UV-stabilized materials, designed to
withstand all but the most extreme
temperatures. PropPastie has remained positioned as shown in up to 51 mph. gusts. Those are the highest winds measured
during the test period. One of the features of the material selected is that it stiffens in cold temperatures. This stiffness in
combination with sewn on Velcro holds the PropPastie in place.
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 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.
When the danger of freezing is past, position the propeller at about 30 degrees off of vertical to discourage birds from
sitting on it. When birds are sitting on the spinner or flying to the tip of the propeller, droppings can enter the
spinner opening. On planes with larger openings such as the Comanche or Apache bird droppings on the propeller
bearings are common. Keep bird droppings off of your propeller bearings and from inside your spinner with PropPastie.
In summer use PropPastie to protect your controllable pitch propeller hub and bearings from water.
Fixed pitch propellers do not have a smaller round diameter at the hub. PropPastie will not stay in place on a fixed pitch
propeller in summer high winds because the material is not stiff as it is in winter.
