Unexpected rapid climb in altitude hold mode #10

Closed tobinfisher closed 10 years ago

330 quad climbed about 40 feet in the air on arming in alt hold mode and continued to climb until I disarmed, at which point it fell very very fast. Might be related to changes in height control interface on app, which I was testing in air for the first time.

Looks like issue was in how the initial hover throttle was estimated. Changing this to a fixed parameter instead of a value estimated based on last throttle before entering alt hold seems to have fixed problem well.
