Product information "KST HS-08B · 8 mm digital HV servo up to 51 Ncm"

KST HS-08B · 8 mm digital HV servo is the new high performance mini digital 8 mm digital HV servo from KST in an aluminum housing with a robust metal gear. The KST HS-08B is characterized by its robustness, high resetting accuracy and a positioning force of up to 51 Ncm (at 6V) with a good positioning speed.

The KST HS-08B servos are particularly recommended for Elysium and thermal models up to 2.5 kg take-off weight (ailerons, rudder and elevator).

Due to the low height of 8 mm, the KST HS-08B is ideal for F3J, F5J, HLG, DLG, F5B and F5D models. The KST HS-08B can be operated with a 1-cell or 2-cell Lipo.

The KST HS-08A is identical to the KST HS-08B, but the KST HS-08A has the servo fastening straps attached vertically for surface mounting. The KST HS-08B has normal standard mounting brackets.

The high-quality full aluminum housing can be fitted precisely and ensures good heat dissipation. Please note the servo recommendation of the respective model manufacturer when selecting your servos.
