Hello.

This listing is for a nitroTraxxas revo and slayer. Everything seen in pictures is included. The revo has a super powerful Sirio motor that requires a new pull start. The slayer has a 2.5r motor. The transmission in the slayer is missing the main drive gear. Both are equipped with dual Traxxas 2055 servos. 

Please contact me with any additional questions you have.

Thank you.
