Need advice on a Crt.5 with Feigao 8L

[miniGranis]

I might be looking to get a Crt.5 with a Feigao 8L and MambaMax.
The car comes with a 3S 5Ah Maxamps lipo.
Can this be rated as a "good" combo ?
(I have no clue of the Crt.5 figures needed for Brians magiccalculator.)

It's supposed to be geared for about 53 km/h (33 mph), will this setup run hot ? Any ideas on the runtime ?

I also wonder if someone can tell me how it would perform with a 2S setup.
