Inertial variometry with instantaneous response and no gust sensitivity.

Do you really think this is possible? How many times did you bump into
a canopy in a rotor? OK this is extreme and yes, I know this is
vertical.

Take a look at Eagle Tree systems:

These guys sell an electronic TE compensated audio vario for RC gliders,
so the vario plus down-link transmitter are small and light enough to
fit into a model. The vario's operating principles are not described.
Its only external sensors are static and pitot inputs MEMs are not
mentioned.
