Motor for an ak

[Earpy69]

Looking for advice 
Iv been offered a cyma ak74u and it needs a new motor, would I be safe getting a somewhat basic/cheap motor as it would I only get used as a backup. (Yes I know cheap=issues) but on a tight budget.

yeah man, just get a basic brushed short motor.  basically 2 types, one with cheap magnets (around £15), one with decent magnets (around £30).  have a look on aliexpress

I recommend the zci 22tpa or shs equivalent
