i am going to build a buggy. ESC????

[BL_RV0]

it will be the hyper 8.5 pro.
motor will be the mega acn 22/35/2.
5s polyquest 2200 20c
(because lutach said his mega ran in a mbx5t for 23mins on a 2200, and in a light buggy, with a slightly bigger motor.....)
gearing will be somehwere around 15/46
calculated, the speed will be 46.19mph.
please tell me if i got the tire diameter wrong for a set of proline knuckles 2.0 tires.
the reason i am building this is to test the components, and decide if it enough for my reggy build.
what would be a good esc? i was thinking the quark 65, because this motor only pulls a max of 60 amps.
