AP420CTF-SNR70E

Airmaster Propeller System

The AP420CTF-SNR70E is a two blade propeller for use on the Rotax 9 series of engines. Its configuration is clockwise/tractor with the addition of a feathering facility.

The performance gain from the AP420 constant speed hub, combined with the outstanding design of the Sensenich E series blade, allows this propeller to perform over a very wide range of speeds. As such it is an extremely popular model, finding application on a wide range of aircraft.

Features include

Designed for Rotax 9 series engines
High strength AP420 CS hub with steel retention components
Fast response from high precision Maxon servo drive
Wide operating speed range from Sensenich series profile blades
Hard wearing composite blade construction with inlaid Stainless leading edge protection

Precision Hub Mechanism At the heart of each Airmaster propeller is a high quality hub mechanism. The single piece hub shell and steel retention parts ensure the hub is lightweight and strong. The high quality aerospace materials used throught the hub ensure a long life with superior fatigue resistance. High strength single piece shell Precision pitch change mechanism Durable steel retention components Fast and reliable electric PC motor
	Simple Operation The Airmaster propeller is extremely simple to operate thanks to the AC200 control system. The automatic management of the engine rpm is essential in reducing pilot worklaod during the critical phases of flight like landing and taking off. Easy selection of engine speeds for Take Off, Climb and Cruise Flexible speed selection using Hold function Precise speed regulation from solid state governor Clear pilot feedback of propeller operation Semi automatic 'Feather' function
High Aerodynamic Performance Airmaster propellers offer exceptional performance and durability with a wide range of blade options. The high temperature cure prepreg carbon technology ensures an exceptionally stiff, lightweight blade. This increased strength allows thinner sections and more complex shapes to be formed resulting in highier efficiencies, over a wider speed range. The R70E blade from Sensenich (USA) is designed specifically for the Rotax 9 series engine. Modern aerodyanmic design ensuring high cruise speeds 70in diameter suitable for high revving engines Strong and lightweight hollow carbon construction High gloss white finish with red tips gives good looks and long life Fully shaped stainless leading edge protecting the leading edge
	Easy installation The installation of the propeller is very straight forward and is designed to be accomplished in a short time by any competent layperson. Included is a very comprehensive operators manual and propeller log book. The propeller comes pre-lubricated and statically balanced with all the necessary hardware supplied.
