Flight mode setup

Go into to the Configuration tab > Input and select the Flight Mode Switch Settings

Every stabilized mode have has a Thrust column where you can select between two altitude modes:

  • Altitude Hold: When engaged, vehicle maintain maintains current altitude.
  • Altitude Vario: When engaged vehicle maintain maintains altitude and his its value can be adjusted using the Throttle stick.

Warning

CC3D and Atom boards does not have barometer sensor and cannot support Altitude Hold.
Only Revolution, Revolution Nano and Sparky2 can use Altitude Hold.

Howto use

...

In normal condition you should take off, hover and next then switch to one of the flight mode modes using AltitudeVario / AltitudeHold. 

AltitudeVario: Around middle Throttle stick altitude do does not change, move stick above/below middle stick to change altitude.

When you quit exit a flight mode using Altitude Thrust, be aware that your vehicle may gain or lose altitude quickly !

Pressure sensor

For best results you should cover the baro sensor with foam and reduce disturbing disturbations from air wind.

The foam must be an open cell foam that allow allows air to pass through.

Another important thing important to consider , : those sensors are really sensitive to light and lighting changes can give produce big jumps in altitude.

Some clones have problems with regulator ripple that disturb pressure sensor, one bypass capacitor C9 does not match the regulator used as replacement by the cloners.

Revolution board

To resolve this issue you can remove the C9 capacitor (better without) or replace it with a 100pF capacitor. Some users reports good results adding another capacitor to regulator output.

...

To resolve this issue you can remove the C8 capacitor (better without) or replace it with a 100pF capacitor.
