12th scale noob question

[fidspeed]

hi guys

possibly dumb questions for you

just bought s/h xray x11 link car for my boy (decent pilot) to have a go with at our local club when re race on carpet

it has a 5.5 turn brushless installed and a 1s lipo ,is that going to be stupidly fast even on 1s . i have a couple of 13.5 or 17.5 that i could use with extreme stock HW speedos would they be quick enough ?

more stupid questions to follow i expect
