Features
Designed specifically for sailplane or similar model aircraft with wingspans of approximately two meters, the Master Airscrew 2.5:1 Electric Flight Pack offers significant improvements in flight performance. With its optimized gearing and specialized components, this pack enables longer continuous flight times and boosts the rate of climb by up to 21% when compared to standard direct drive motors.
Complete Component Set
The flight pack comes fully assembled and includes everything needed for straightforward installation. At its core, it uses a robust 7.2V 05 Ferrite motor, complete with pre-installed capacitors for smoother electrical operation. To maximize efficiency and durability, the gear reduction unit features 3/16 inch steel shafts that are guaranteed against bending, and the molded output gears are mounted on twin ball bearings for precise and reliable performance.
Enhanced Propulsion System
A notable part of the package is the 12x8 folding propeller, crafted from glass-filled nylon. This material not only ensures strength and durability but also contributes to aerodynamic efficiency. Accompanying the propeller is a sleek black spinner and a comprehensive motor mount, complete with the necessary hardware for secure assembly.
Tools and Documentation Provided
To facilitate an easy and proper setup, the package includes a hex key perfectly sized for the prop shaft set screw, an instruction sheet that provides step-by-step guidance, and a wiring diagram. Enhanced user support is a focus, ensuring that even less experienced model builders can easily set up the system.
Additional Requirements and User Notes
While the flight pack is largely ready-to-use straight out of the box, users will need to provide their own wiring harness and a compatible 7.2V battery, as these are not included. The unit is designed for quick and hassle-free installation, making it an ideal power solution for pilots who want to upgrade their model aircraft with minimal effort and maximum performance gain.
