I got the 55KG Waterproof Brushless servo Full Metal Gears High Torque Fast Digital Servo to go with one of my roller chassis RC cars, It has some heft to it and feels solidly made. It dropped right into the vehicle with no issues. I am using it for the steering servo and it has plenty of force to move the big tires around. I cn recommend the 55KG Waterproof Brushless servo Full Metal Gears High Torque Fast Digital Servo!

I use this servo as the throttle/brake servo on my nitro truck, and it works great (probably overkill for that application but, whatever).Good speed, good strength, and well made.
