I’ll be building a 1/8 scale nitro buggy here shortly and am newer to the scene. Had some questions I guess and or recommendations as to what you guys would suggest for servos and receiver battery. I haven’t picked out a rx/tx yet but am still trying to make the knowledgeable pick.

I have been looking at Spektrum 7954 and the Protek 130T. Seems like torque and specs would fall into the 1/8 scale class. I have a budget of around 80-90 bucks per servo. And looking at running a 6.6/7.4v receiver battery if 7.4(hv) can be used. I see a lot of people saying to not use the same throttle/steering servos, but as someone who is new to this, is it that big of a deal/difference to narrow down a better throttle servo. I have somewhat stayed away from searching the Savox servos just due to the fact that I read a bunch of things on them and using spectrum RC. Again, I am newer to the scene and you guys may have some better/updated info. Thanks for reading
