Hi @oscardelta59 and welcome aboard.
Although a mapping command for the governor switch is not yet available, one will be introduced in the next update.
As for the starter, maybe try mapping your button to ‘MAGNETOS START’.
For information about what else might already be in the development pipeline, please check out the Road Map at FlyInside Bell 47G Road Map - General Forum - FlyInside Helicopters Forum (flyinside-helis.com)
Cheers
