Using functions in Hooks question.

[propeler]

HI.

I found hooks to be good alternative to adding my code to Export.lua. But I'm facing some problems of using functions which are available in Export.lua.

By the instance in Export.lua I can call 

get_param_handle("BASE_SENSOR_PROPELLER_RPM"):get()

And it works. But I can not find the way how I can call it from the hook. As when called from hook it is not present in global context. Will be much appreciated if someone can give a tip how to call that function from the hook.
