12 is perfect, 13 when you need a little more on the straight. I would use 12 on a hard-packed clay-track, 13 when racing on asphalt/concret and such. Hope this helps :)

...i run and HPI micro 12 but i will be fitting a 13...Using the 12 pretty takes out the meshing mysteries...it slides almost to the end of the slots and tightens the mesh slightly after you have done up the mount screws...
