Spend the extra $75 and get a DX3r at rrphobbie.com they have them for 209 in the cart I just bought one shipped for 227.00.
Servos well high torque for steering and high speed for throttle. Especially with a truggy you need really high torque above 200 oz at a minimum for the steering. I have been happy with the ACE servo's. I have ran the TG Hitecs also. You need to break out the bank on the radio and servos if you want to be fast. Best of luck to you.
