Hey Wolfgang,

  

 Sorry to hear about your AP Troubles.   What did TruTrak have to say about your complaints to the malfunctioning  of their unit(s)?  Curious to find out what their  position is...

TruTrak AP won't  work....must be a Rocket thing??!!!  Seriously, I take it you've talked to  TruTrak and have sent the unit in for checkout?  TruTrak is pretty diligent  about customer support and there are a LOT of perfectly satisfied users, myself  included, though with a TruTrak VGSV (or whatever) in a Velocity.    After a couple months of original installation, it would wonder R/L at its  pleasure.  TT fixed it (an electronic gyro issue) by sending a new unit  Next Day with the understanding that I would send my unit back when I got it  removed from the plane--pretty trusting, I would say.  Since then, it locks  on altitude and lateral path like a bulldog and doesn't let go.  Sound like  your unit needs a little fixin' or, if the data stream is coming from an  outside source, that that should be checked  also.  

  

 I have absolutely no  first hand familiarity with the Magician, errrr Sorcerer, but I, and most people  I know, give TT the benefit of the doubt when it comes to AP design and  service.

Hi  Wolfgang,

  

 I'm  sure you've already checked the obvious (static source, wiring)?  Will  yours hold altitude once set?

 I'm  running the TruTrak with altitude hold, and GPSS coupled to a CNX80 (480  now).  After initially tuning as per the manual, I just love my  autopilot.  

 To  make it work right, I did have to do some tuning, but the manual worked good  here.  I don't fly heading too much, but in the beginning, it would loose  heading every now and then, but I think it was more because I was doing heavy  banking just before I activated it.  If I do a roll, and don't wait at  least one minute, the AP is very confused.

  

 Regards,

 Jeff

Chuck, 

  I can't believe we are discussing the virtues of autopilots on the coolest personal fighter, acro machine, dogfighter ever designed, but here it goes.  My 96' HR2 has a Navaid devices AP installed before I bought it and it will track a course and level the wings when I want it to. It's updates are primitive and somewhat ratchety compared to the 737-700 but it works and is a nice option if I'm in the goo and doubles as a T&B. 

    I also have a TruTrak ADI which gets it's data stream from an Apollo gps. The ADI works but the heading falls offline unless you scale the map down to 1 mile scope (higher baud rate). Additionally. the ADI precesses quite a bit after aerobatics so I pull it's CB unless I need it to fly IFR (which is rare). Pitch isn't actually pitch, it is vertical velocity which could be good or bad.  Possibly the issues addressed are the pitch update rates on the TT. Maybe it can't hack the rapid changes presented by  the Rocket inflight.  Having seen the TT ADI in action, I wouldn't buy the AP. That's $3K worth of 100LL brother!

    I have seen a Navaid Devices AP online selling for $400 complete. Not a bad price and it works.  I don't use mine much as I have a tendency to roll upside down quite frequently and roll in on unsuspecting 421's, Baron's, King Airs, Navy T-34C's and even a few squadron mates in F16's... That's what Rockets were designed for, right?
