Xpert R3HV Quick Release High Speed Low Profile Brushless Servo
I'm using this low profile servo in my 2wd off-road buggy in both mod and stock spec classes. My favorite feature is the quick disconnect servo leads which makes it considerably easier to shorten the lead and clean-up your electronics install. In fact, in the box they include a couple different lengths, the shortest one was perfect for my buggy.

This servo is very fast, consistent, and overall feels great on the track. Zero complaints!

Xpert R3HV Quick Release High Speed Low Profile Brushless Servo
I bought 2 servos and they have the same problem. After I missed a jump, or tap a wall, or hit another car, the servos will not recenter. I am mostly an A-main driver, so my driving style is very conservative and I rarely crash. I contacted Hobby Authority Distribution and they said, "Typical conditions that are considered mishandled and not covered by the factory warranty: Physical/mechanical damage due to external impact." So, If you hit anything at any time, according to the Hobby Authority Service department, it voids the warranty.

Therefore, if you are a perfect driver, then this servo is for you. If you have any accidents, or contact with any physical object ever, DO NOT BUY THIS SERVO.
