| 1.) yes, the servos on a eCCPM heli MUST be the same! if you like jr servos then use the best servo that they have that you think will work good.
2.) yes, they do make a metal auto hub, but for the EVO 90 it isn't needed.
3.) the two metal auto hubs that you listed are different. the silver one doesn't come with the bearing and needs to have the "grease mod" done to it for it to work good. the black one has a HD oneway bearing included and has the grease mod done to it(sort of). |
