Funny you should mention it ... i actually do. I might take you up on that offer!
Thanks!
PS: first and foremost I gotta get the panel of the Cherokee fixed. It's a bit ... crappy. Old instruments and all ...
Don't do anything on my account...

"steam gauges" to make sure they work is a pleasant diversion on long, boring flights...also fun for scaring newbie pax before takeoff...

Seriously- good idea. If you're ever going to fly in IMC for real in that bird, make sure you're good to go. Sell the back seats if you have to... I'm sure it's not cheap to do it right, with backups, etc. :-X
And I'd guess even just for practicing, not having a solid set of instruments would not help any.
