Aim Top High Torque-Up Motor Long Type

The Aim Top High Torque-Up Motor Long Type is a motor that can be fitted as an upgrade in an AEG and is particularly suitable for set ups with a heavier spring.

This motor involves a 27K motor which is a higher RPM than the motor that is standard in a new replica. High or Ultra Torque motors are generally most commonly used in builds with a heavier spring. These types of motors are perfectly suited to allow heavier springs to be tensioned. Think of M120 to M160 springs.

TPA: 18

TPA means revolutions per armature. The Armature is the central shaft in the airsoft motor on which the wire is wound. How many times the wire is wound means TPA. So 22 TPA means 22 stacks of wire wound on each side. The more wire, more magnetic field, more torque, but also more weight and less speed. Also, the higher the TPA, the less trouble from overheating.
The higher the TPA, the more Torque, the lower the TPA, the more high speed.
