I flew with XC soar 6.3 and the AH actually worked (looks like an actual AH,
globe blue top/brown bottom). It seems to function fairly well...but i
could not figure out how accurate it was. I think it was simply using GPS
alt and heading...not really a gyro funtion becuase it was easy to trick
with skids, slips and inverted flight. This was the first time I have seen
it function. As much of a toy as any other mobile based AH, but neat! Well
done Max and team.

As to the arguments that LXNAV is exempt from firmware requirements via USRC
(when Butterfly and others are not) to be legal to fly in US contests...I
simply disgree. The current LXNAV firmare has the AH mode code needed to
utilize harware which going to be burried in the panel or elsewhere.

The LXNAV firmware is ready to go, AH capable (this is a fact)...and nobody
is going to check to confirm if the AH box exists or is plugged in. Do the
only way to be sure is to require special firmware as butterfly has built.
Dangerous stuff indeed.

I think the RC needs to clarify this...

As for the personal comments I am amused. This should not be that
emotionally stimulating...

Hi Sean,

I don't see anyone saying that LXNAV is exempt from anything. But it seems
to me that LXNAV has already met the requirements in the same way that
Butterfly has. The AHRS can be disabled for 14 days. And/or it can be
removed from the glider. I don't know what could be more rules compliant
than that.
