interested in speed

[pointhwerp]

well i wouldnt mind buying 2 motors, but 2 controllers isnt happening, least not for a while, so i could get a 9l for the zilla and maybe the 8s or lehner (though its alot more $), i have a 7 cell now, but its old so ill replace it with an 8 cell most likely

so would the 9920 be fine with both of those? that way i can pull out the controller easily

how would i gear it anyways, 18/87? thanks for the help so far :)
