Prop Tip Mod Sensenich or Mcauley$300.00
The world-famous Art Mattson prop tip mod! With this STC and your prop in good condition, you can have your favorite prop shop do the mod.
For most aircraft, the propeller can be pitched 2″ coarser with no effect on static rpm. That means you can choose to leave the pitch alone and increase climb performance, pitch it 2″ coarser and increase top speed without hurting climb performance, or split the difference at 1″ coarser and improve climb and cruise!
