The new
KST A08 LV is a great
low voltage fully metal cased servo weighing only 8g (0.3 oz). This new
LV version is optmised for use on 1S LiPos. Unlike the X08 the A08 incorporates a complete case that covers the motor, making the servos much tougher and less susceptible to water ingress, handling and crash damage. Despite this the A08 servo is actually lighter and has more torque than the X08. The A08 is also slightly smaller than the X08, making it suitable for very tight installations.
The KST A08 LV is especially good for ailerons on discus launched gliders, and all models with thin flying surfaces that use 1S LiPo batteries. Despite being only 8 mm thick the powerful coreless DC motor and gearing provide good torque and high speed. KST servos have excellent geartrain machining tolerances, and this servo is completely slop free, and equal to products costing twice as much. Despite not having an -MG moniker this servo has metal gears, and is very tough.
The KST A08 LV's high torque, good speed, and 8mm thinness make it suitable for most 1S LiPo powered high performance gliders. The accessories include three strong nylon output arms, two double sided, and one single sided, one of which is low profile. This means that when the servos are mounted one in front of the other the control rod of the front one won't foul the rear one.
The KST A08 LV is fully programmable using
KST's new programming tools.
The extreme reliability and performance of these servos also makes them very suitable for use in film and motion picture industry special effect departments. They are also used in robotic, drone, UAV, UAS, academic research, military, and other highly demanding applications.
