Quick question: Does the TT-02 require a low-profile servo, or can any standard-height servo fit? For the two kits my step-dad & I will be building, the servos are about the only remaining items to purchase. Also, if anyone can recommend what torque range is best for the TT-02, I'd appreciate it. My step-dad's will have (at least for now) the stock plastic steering bell crank, while mine will have the aluminum.
