Taigen Tanks Zinc Alloy Gearboxes

These are a stock pair of zinc alloy gearboxes for Taigen tanks. These zinc gearboxes are usually installed in the plastic edition tanks and are not recommended for our heavier metal edition models.

Taigen Gearbox Information
Common terms:

High/Low or Mid/Low - Refers to the motor mounting positions on the gearboxes. Some tanks have the motors mounted in different configurations for height restrictions for one example.

3:1 and 4:1 - Refers to the amount of reduction gears to the final drive shaft. The actual ratio for the 3:1 gearboxes are 39:1 while the actual ratio of the 4:1 gearboxes are 90:1. The 3:1 gearboxes are faster but have less torque while the 4:1 gearboxes are much slower and offer much more torque. The 4:1 gearboxes are recommended for metal models if possible.

45mm, 48mm, and 58mm - Refers to the final output shaft length of the gearbox. The two common shaft sizes are 48mm and 58mm with the 45mm version being for the Sherman tank only.

380 and 390 Motors - The stock motor for the Taigen V2 gearboxes is a 380 sized motor (28x37mm) @ 18k RPM while the 390 motor (28x47mm) @ 25k will produce not only more speed but torque as well.
