| 10 | * The InvenSense gyros have a lower sensitivity than for example the ADXRS610s on the FC 2.0 ME, |
||
| 11 | * but they have a wider range too. |
||
| 12 | * 2mV/deg/s gyros and no amplifiers: |
||
| 13 | * H = 0.002 V / deg / s * 1 * 1024 / 3V = 0.6827 units/(deg/s) |

| 18 | * Correction factor - determined experimentally: Hold the copter in the hand, and turn it 90 degrees. |
||
| 19 | * If AnglePitch or AngleRoll in debug in MK-Tool changes by x degrees, multiply the value here by x/90. |
||
| 20 | * If the hardware related contants are set correctly, flight should be OK without bothering to |
||
| 21 | * make any adjustments here. It is only for luxury. |
