BMS-M15H Vertical Mount Micro Servo

We believe the M15H has the potential to become the new benchmark servo for F5J and many other sailplane applications. Similar in size to the 115HV, the M15H features an all metal case and a magnetic sensor instead of a traditional potentiometer. 

The M15H is precise, and offers another level of durability. In addition it is extremely quiet with no "buzz". It features a servo lead that is removable. You have the option of soldering this lead directly to your wing harness to help reduce weight in your model. 

Servo trays are being developed but it will fit in 115HV frames with slight modifications. 

We have extensively tested this servo in our Prestige 2PK F5J model with fantastic results. 

More information coming soon.
