That should™ work, but especially in truggy, bigger is better for torque. It not only holds better, but moves the giant gyro wheels much easier and doesn't have as likely a chance of an issue when you come down in a cartwheel with such side force. I generally suggest 300+ for buggy and 400+ for truggy (and have the PT170s .07/549oz in mine). HV servos make hitting those numbers much more feasible these days.
