That may be true but, from my experience, they didn't make it work
very well. I have to set my slow alarm threshold well below 1 g stall
to stop it being a nuisance while thermalling. I like to crank it up
tight in our southwest thermals. With that setting though it is
useful as the 28 climb rate really falls if if flown too slow.
