And what about sonar, barometer and gps?
From my early point of view:
The only reliable height hold is possible via sonar at low heights (up to 3 Meter?)
A barometer is very sensible about wind - and a copter is a very windy place ;-) Height hold via gps depends from the accuracy of gps that is imho 3-5 meter.
With some mods, like encapsulating the baro and a sensible IMU, the copter should hold its position with a slight oscillation of +/- 1-2 Meter.
Some copter sw has sonar/ gps/ baro implemented, some not. I would apreciate if someone implement sonar support into multiwii - because its christmas ;-)
