What prices are beign quoted/paid for compliance with the flutter AD
(addtional mass balance required)? Who seems to be doing most of them?
Gron systems? What about the spigot AD? Lastly, what's the best source
and price for a new canopy? Thanks in advance!

Stephan,

I have been in contact with Mike Shade at Grob systems in Ohio,
the flutter AD costs will be material cost about $600 US and 15-20
hours labor at $60 US / hour. That adds up to OUCH !

I don't know about the spigot or the canopy, but ask Mike.
I have sent his email to you directly.

Enjoy your Grob.
