If you're running a series that allows brushless in stock 12th get the 13.5 motor. The 13.5 is faster than stock in 12th.

As much as I would like to say use the Novak speedo for brushless, the LRP is about the same price and is a half ounce lighter.

From what I saw last night running the 13.5 it's about a lap faster.

Start with a 2.20 rollout on the 13.5 in 12th.
