For your engine the Collari .21's are awsome so is the p5x, but they are a ton of motor. Being you are new to 1/8th scale i would recomend some thing with less power. The os .21 rg is very competitive on a tight track, and great for a new driver. When you feel comfortable with the buggy you can bump up to a nicer motor, and you will have a nice spare just incase.
