This disables the current estimation for fixedwings. Unfortunately the commands are named differently for fixedwings and rotorcrafts.
Probably better to use something like
```
#if defined COMMAND_THROTTLE
#define COMMAND_CURRENT_ESTIMATION COMMAND_THROTTLE
#elif defined COMMAND_THRUST
#define COMMAND_CURRENT_ESTIMATION COMMAND_THRUST
#endif
...
#if defined MILLIAMP_AT_FULL_THROTTLE && defined COMMAND_CURRENT_ESTIMATION
...
float x = ((float)commands[COMMAND_CURRENT_ESTIMATION]) / ((float)MAX_PPRZ);
```
