    Great advice, Greg! Fly the airplane for a year and enjoy it in all its steam-powered glory, John. As Clouddog says you'll probably find that there's something else you'll need before an IFR panel. And the gyro that's in it, if working, is perfectly capable of getting you through a cloud layer on a radar penetration if you get caught out over the top of an overcast. Don't ask me how I know that. For all the years I flew Delta 777's with its swanky glass, I found it a treat to get into my unmodified CJ-6 and fly it "old style." Have fun!

    Great advice, Greg! Fly the airplane for a year and enjoy it in all its steam-powered glory, John. As Clouddog says you'll probably find that there's something else you'll need before an IFR panel. And the gyro that's in it, if working, is perfectly capable of getting you through a cloud layer on a radar penetration if you get caught out over the top of an overcast. Don't ask me how I know that. For all the years I flew Delta 777's with its swanky glass, I found it a treat to get into my unmodified CJ-6 and fly it "old style." Have fun!
