Steering and Tranny Servos
For my RC4WD Trail Finder2 build I decided to use HS-5646WP High Voltage, High Torque, Programmable Digital Waterproof Servo
I really wanted programmable servos or servo for the steering because of the small servo I am using for the functional steering in the cab I needed to make sure I could reverse the direction of the servo with having the need to use a reversing Y, this allows me to have 1 channel drive both servos.
Using this particular servo for the 2 tranny is over kill (180oz) but then the metal gears, digital and waterproof was also important.
This truck will not be going underwater but it's nice to have to know if snow or rain gets on them there not going to fry.
