Thank You, I failed to mention the servos I am using are four Power HD AR-3606HB CR, they performed exceptionally well @ 6v. My steering servo is a Power HD High-Torque Servo 1501MG, it provides plenty of power to steer my robot in any conditions. I also have two of your step up-step down boost regulators in my design. I hope to link some outdoor FPV soon, to place the robot in the element it was designed for. Being made of aluminum, stainless steel and nylon, I wanted it to withstand storms and send back weather and other sensor data.
My area of work now is concerned with weatherproofing the electronics, on there own deticated boards.
