I usually replace my tail servo on a 450 with Futaba BLS257 but, now these days i think futaba needs do some catching up. So I stuck between 2 servos BK DS-7005HV and MKS HV9780. Anyone use them in 450 size? Thanks |

Does BK make the 7005hv with a standard case top? I run a BK 7005hv in a 700 and the case top is oversize for full size servo mounts. |

I just knot iced that too. I wonder if it would be ok to use the cyclic version (5001HV) ? |

RJX and BK servos are very similar. RJX makes a mid size tail servo with a normal case top and same specs as the BK 7005. This is what I am trying once I kill my current 450 tail servo. |

The cheaper one is has almost 2 the torque but longer and heavier. The other one is smaller lighter but the torque is about equal to mks. I'm leaning to MKS for 2 reason.
1) Titanium gears
2) No stop pin in the gears. Mks servos spin 360. So in theory much harder to strip any gears. |

Well I went with MKS and I'm glad. My buddy just witness a BK tail servo fail in flight. |
