About the ILGoblin Pro 520

Tail Servo Positioned for Optimal Balance

The ILGoblin Pro 520 features a front-mounted tail servo, an intentional design choice that enhances the model’s center of gravity. This configuration improves overall flight stability and agility while also allowing compatibility with both mini and standard-size tail servos. By shifting the servo forward, SAB ensures better mechanical efficiency and ease of access during installation and maintenance.

High-Efficiency Transmission System

Equipped with a 12mm one-way bearing and 13mm motor belt, the ILGoblin Pro 520 is built to handle high head speeds with reliability and minimal slippage. The adjustable main rotor ratio ranging from 4.47 to 5.88:1 and tail ratio of 3.88:1 allow pilots to fine-tune the drivetrain for optimal performance across flight styles. Combined with durable construction and precise machining, this transmission setup ensures smooth power delivery and reduced wear.

Lightweight Components with Enhanced Aerodynamics

From the molded carbon tail boom that weighs only 100 grams to the sleek new canopy and orange SAB blades, every component of the ILGoblin Pro 520 is optimized for performance and visual appeal. The helicopter includes 520mm main blades and 82mm tail blades, contributing to a 1220mm main rotor span for impressive lift and control. The updated plastic ball linkage system also offers improved strength and reduces routine maintenance, ensuring the model stays tight and responsive over time.
