My STEC 55x may have just died and even though I can probably get it fixed or a buy a yellow-tagged replacement, it could be time to upgrade to a DFC 90. I have an Aspen Pro 1000 with an ACU. I know I’ll need a software unlock for the Aspen. Anything else? Also, do I get the flight director and altitude preselect? ------------- ------------ dave |

I envy you. If I had servos I'd do a DFC90 in a New York minute. ------------- David Gates |

The DFC90 is a fab bit of kit, but available only for three different airframes? So unfortunate. * Orest |

It is a shame that Avi abandoned this project, I think cert costs were the tipping point. ------------- David Gates |

Just to close the loop in case someone else wants to go down this path. A Aspen with an ACU and an externally mounted RMS plus the software unlock is all that is needed to drive a DFC 90 which gives you altitude preselect and flight director. ------------- ------------ dave |
