Top Tier
The Vertex VX-HV20D is by far one of the strongest and smoothest servos on the market. The metal case combined with the performance you get with high voltage makes for a "locked in" flight performance only rivaled by the likes of balsa aircraft. They are definitely not the cheapest option but for their performance you wont be left disappointed, these really are the best of the best for 39" to 48" foamies or balsa airplanes!
