If you are going to use analog servos, then it will be OK.
Just make sure that your battery and switch wires are HD gauge wires.

I just started building my funtanna 90 and plan on useing a 6 volt 2000ma battery pack, with 50oz + servos. my question is do i need to use heavier wire for my servo extensions or will standard size be ok.
