A64pilot is correct. Scanmar bought CPT and then pretty much abandoned it, about a dozen years ago. Jeff bought CPT from Scanmar and did a proper job of resurrecting a great old simple strong
autopilot, as well as setting up a proper business model with great
service and support.
Then he set about to 'modernize' the internals to make them more accurate and easier to use. The new CPT has all the simplicity and
power of the old one so I expect it will be just as reliable. I dont think the units are interchangeable, so I dont think you can buy an old one and make it a new one. BUT, Jeff will
rebuild your old one for a nominal fee.
If you call CPT he usually gets on the
phone and will answer all questions. But he's gotten so busy the past year he does prefer
email because he can answer them during breaks. I'm sure you businessmen out there will understand...
