Bolted Joints
Bolted joints are pretty simple. Drill some holes, drop a bolt into them, add a washer and a nut, and torque to the...
Fixed Pitch vs. Constant Speed
Deciding to use a fixed-pitch propeller or step up to the higher weight, cost, and complexity of a constant-speed prop in order to improve performance.
Fixed-pitch Props
A major advantage of a fixed-pitch prop is that it is lighter, simpler and cheaper than one with variable pitch.
A Bit About Blades
Like a wing, a propeller blade is characterized by its area, planform, and airfoil cross section.
Blade Inflow Angle
As the propeller moves through the air, each point on the blade follows a helical path.
Prop Momentum Theory
Proper selection and design of the propeller is one of the keys to airplane performance.

Pilot Proficiency
If you've spent years building instead of flying, type-specific training before that all-important first flight in your homebuilt is a must.
Cooling Outlet Design
The design must focus on sufficiently cooling the engine while minimizing drag.
