Dave,

First, thanks for all this work for the soaring community.

Questions - Why didn't Air Avionics (nee Butterfly Avionics*) resolve these issues rather than you needing to step in? Has the company orphaned software updates for the entire line of Butterfly devices (which I think has been sold as late as 2017)?

I get that no device's support goes on forever. But to me this doesn't lend confidence with this manufacturer.

Your take?

Thanks again,
John

Actually, a manufacturer releasing the source code to a 3rd party to update an obsolete product is highly unusual, and exemplary support. It is almost unheard of. Now I wish Air Avionics would do that for the Butterfly vario (still the best in the world).
