Do the aluminum pulleys and tail gear help performance?

[Clay333]

I have heard people talking about the aluminum pulleys in the forums and was wondering if they actually help performance or if they are just bling. I am putting together an order from experiencerc that includes everything Scorpion /MSH 880kv motor and a few other small things. I don't have much extra cash to spend so if I buy something I want performance, i couldn't care less about bling. If they do help performance is there a certain brand that's better than the others? I noticed they had Duzi, MSH, and I think one other brand. Hopefully someone with experience can chime in and tell me if it's worth the cash. Thanks

Also does anyone know what size motor bullets come on the scorpion motor? Does the motor include female bullets for the ESC?

I like the aluminum rear tail pulley/gear. The plastic ones tend to have lateral wobbling. Not a big deal but still prefer the aluminum.

I prefer the MSH one because it doesn't have the side walls. They are not needed because the pulley in front of it provides all the guiding.

The MSH motor and YGE ESC that got over a year ago each had 3.5mm bullets.

I think I'm going to hold off on ordering them right now. I'm sure I will probably grab them later, just trying to get essentials right now.

That sounds really small for the bullets. I know both lipotech motor is have gotten used has either 5mm or 5.5mm. I am pretty sure I have some 3.5 mm laying around so I will be good. Thanks for your help
