HobbyZone Motor and Gearbox (Champ)


This HobbyZone, Ultra Micro Motor and Gearbox features a wide-mount, 4:1 ratio gearbox and short-can 8.5mm coreless motor.  With some trimming of the gearbox mounting tabs, this product can be used as a replacement for the PKZ3624 motor and gearbox. This combination originally found service in the HobbyZone Champ and features a shorter motor connection lead and slightly reduced power consumption over the PKZ3624.

If your application allows, consider the upgraded SA8523 product, available in both wide and narrow mounting configurations.

Additional Details

For those curious, we’ve made several static thrust tests of this motor and averaged the output. These tests were made using a (fresh off the charge) Hyperion G5 130mAh 1S 3.7V LiPo (50c), SPMAS6410L receiver/esc and conducted at 6500′ ASL, at 70°F.

Measured Static Thrust: 30g (1.06 oz) of static thrust with 130mm x 70mm (EFL9051) propeller.
Measured RPM: 6600

Note: Our tests were performed at high altitude where propeller efficiency is reduced, these may vary somewhat from data obtained at lower elevations.
