Description

The new KST MS325 is a breakthrough servo. high reliability servo that uses Hall effect (magnetic) position sensoring to do away with the unreliable and limited life potentiometer (pot) that has been a thorn in the side of RC models until now. This advanced KST developed technology has the potential to revolutionise the RC servo industry, with servos no longer the least reliable part of the RC control system. This increased reliability will make these servos the preferred choice for all high value/high energy models, and for the UAV industry.

The KST MS320 has a good 5.2 Kg.cm torque with a really good 0.07 sec/60° rotation speed. This makes it particularly suitable for cyclic on Goblin 380, Trex 450 and larger helis, and control surfaces of large fast models up to 6 Kg in weight.

In addition to the contactless/magnetic position sensor, these high voltage (2S LiPo capable) servos use zero slop hardened steel gears, aluminium alloy cases, and well designed electronics to deliver the best performance at this size and price point. The combination of no free play in the geartrain and the ± 100º rotation range gives these servos the best resolution of any on the market.

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.

KST MS325HV

For the small extra cost these servos represent a huge step forward,as any new builds of mine will now be HV, these will become the standard fuselage servo.
They are fast! Centre to perfection with more than enough torque, why wouldn't you use use them?
Superb next day service from Neil, thanks!
