Another report on the new CNv from a user in the states. I concur on 1 sec time constants for pointer and audio. The vario signal is very smooth at this speed. I am in love with the new climb audio!! It's much better at communicating lift in the 0 - 3 kt range than anything Cambridge or "

Thinking about it, I have had 3 failures, all in state comps. The first two were due to rain getting in the statics, so the Winter varios did not work either ( tape up the statics if rain imminent) and the other in Keepit’s LS7 when two well meaning individuals ‘fixed’ the vario just before laun

Not a failure as such. But I did do a flight in a club aircraft with only an airspeed indicator, altimeter and a radio functional. I knew that was all that was working at take-off though. I flew in thermals for over an hour. Fortunately the launch before mine marked a thermal for me. But
