Last week Maxime De Moro ask for a customized H4 Full metal brushless digital servo with his name on it.
We just made one set of H4 servos for him.
Here you can some data of the H4 full metal brushless digital servo.
H4 Series High Voltage Brushless Digital Servo is RC OMG's lates Servo
It is a powerful, accurate high torque precision digital servo with its full metal aluminum case, long wear 7075 Aluminum anodize titanium gears plus 304 stainless steel gears, a precision brushless motor and improved electronics, legendary quality.
It can be capable for 4.8 to 8.4 volt operation.
It get high torque 20Kgf.cm (250 Oz.im) at 7.4V
The grooved middle case takes a whole new galaxy of performance.
RC OMG provide legendary digital precision with higher torque and faster speed servos.
Key Features
Super high 12 bit (4096) resolution
Robust output for superb response in extreme maneuvers
Zero dead band assures legendary precision
Aluminum middle case helps dissipate heat
Digital precision provides great accuracy and performance
Ball bearing-supported output 25T shaft
Compatible with all types of Radio system
Pulse width travel is adjustable
Applicable for the 1/8 th Buggies and R/C Helis Cyclic Swash Plate (700 series and larger)
