Launch acceleration should be multiplied by vehicle mass when calculating launch force.
10 m/s (1g) is much too low for a hand launch. 25 m/s (2.5g) over a shorter period is more realistic and will trigger the recommended value of TKOFF_THR_MINACC of 15 recommended for hand launches.
Rework after review:
- Kept old IMU and barometer definition of crazyflie 2.0 in hwdef
- Added comment regarding soft-reset command
- Added defaults.parm for crazyflie
