What size is your track
At our local carpet hang out 90x45' area
17.5 blinky is Wide open all the way around @ 95 to 100mm roll
If your track is half that size, I image a 21.5 might feel the same ?
The speed of the motor won't be a learning curve at all
However, adjusting to the cornering speed of a 12th scale takes some getting used too, if coming from Sedans, or Off-Road
72t spur is correct
