MT-Propeller’s fast, lightweight composite propellers reduce weight, vibration, and drag while increasing lift, thrust, and lifetime operation. These 4- and 5-blade propellers maximize the benefits of a Blackhawk engine upgrade. 

UPGRADE BENEFITS

• Reduced Weight – Lighter than aluminum, natural composite propellers reduce weight on the engine crankshaft and overall aircraft weight.
• Reduced Vibration – Unlike aluminum, composites do not experience harmonic vibration. Gyros, motor mounts, radios, heat muffs, cowlings, and more enjoy longer life with reduced vibration. 
• Greater Strength – Composites are stronger than aluminum. 
• Unlimited Blade Life – Composite propellers are brought back to exact factory-new dimensions during overhaul, avoiding replacement.
• Steel Hub Inserts – Steel bearing inserts eliminate the requirement to replace the full hub when tolerances are exceeded. 
• Quieter – Shorter blades and increased blade count results in a smaller diameter and lower, quieter tip speeds. 
• More Lift/Thrust – Lower tip speeds maintain smooth airflow, resulting in more lift/thrust. 
• Less Drag – A smaller prop arc disc creates less drag than larger diameter prop arc discs. 
• More Ground Clearance – Smaller diameter propeller blades reduce chances for prop damage from ground objects and debris. 
• Added Resale Value – Upgrade benefits are passed along, increasing resale value. 
• Easy Installation – The blades bolt on easily and use the existing prop governor. 
• Full Warranty – 1 year or 1,000 hours (whichever occurs first) for any manufacturing defects.
