    Hi,

    I've decided on a SFX-100 build and have started sourcing parts.

    I'm a little confused regarding the motor choice. In the SFX documentation shopping list there is a link for the motor (type 90ST-M02430 220V 750W) that points to an Ali Express seller. There are 20 (!) different versions to choose from... The first one in the Ali Express list is "Speed: BK Version A" but there are 19 other versions.

    Does anyone know which one I need to purchase?

    Figured out which version to purchase. Problem is that the link from the SFX-100 shopping list points to a 2.4Nm motor but in the description for the Actuator on SFX-100 website it says the motor has 7.5Nm of torque. Does anyone know or have experience from building the SFX-100, is the 2.4Nm motor strong enough?

    7.5Nm is the peak torque of the 2.4Nm servo...
