CHASERVO HV85H Mini Servo CHA-HV85H
This is sport.
The HV85H is a powerful and precise HV servo that promises long and reliable precision work thanks to its robust design with steel gears, double ball bearings and aluminium housing.
Thanks to its compact design with a depth of only 8.5 mm, the HV85H series is particularly suitable as a wing servo and enables thinner wing profiles for improved aerodynamics of the model aircraft. The range of applications extends from glider models and motorized models to high-performance jets.
Robust. Precise. Powerful
The Chaservo HV85H is a powerful and precise HV servo that is characterized by its compact design and high performance. It is ideal for a variety of modeling applications, including RC airplanes, gliders, powered aircraft and other models that require high performance and precision in a small package.
