SP150 setup questions...
 

Owwkey.. I'm having a hardache with my SP160 setup.. now i'm planning to downgrade it.

Is it fine to have these upgrades..

Guarder infinite helical gears.
EG700 motor
9.6V 2400mah.

thanks

+metal bushing +shims +bearing spring guide yep fine
hope these go in a MP5K :)

how many hi-caps (300 rds) in this setup should i expect?

and I also wanna know how huge is the difference between SP160 and SP150.. I already have an infinite gearset and still, it won't give me a decent amount of rounds.

I don't think anybody on this forum can reliably answer that question for you. There are very very very few people here who upgrade their guns that hard, and even if they did, they aren't allowed to use them on Canadian fields, so field-use data would be non-existant.
