 Mike,
Find Kirk Hammersmith.  He has GPSV guidance and is using the TruTrak
 autopilot in his ES.  It is on a "beta test" basis. He is also using it
 with the Chelton EFIS.  I also spoke with TruTrak over the phone a few
 weeks ago. In fact, they had me send in my DFC 250 for upgrades.  They
 indicated that there isn't much difference between the Sorcerer and
 DFS250 and once the programming issues are resolved they would upgrade
 my DFC250 to provide for GPSV operation.  I would be interesed in what
 Kirk has to say.
 
 Thanks for your information.  I wish I could have made it to SNF but it
 just didn't happen.
 
 Also, you should check on available deice equipment.  TKS or Northcoast
 Technologies Thermawing would have products.
 
 Thanks,
 Bryan
