For a good glider T&B you need a 30 second standard rate not a two minute.
The TruTrak over indicates but not by that much. They also suggested that
it operates best over 50 knots.
They need to provide a way to re-calibrate it for gliders.

I received one of the first TruTrak solid-state (no gyro) T&B indicators
last week and flew with it last Saturday. For a full report, go to
