5 components of powertrain?
main trans modules, drive shaft, oil cooler, IGB, TGB.
Primary and secondary fuction of the Main trans?
take combine power from the two engines, reduce RPM's, and transfer it to the main tail rotors.

secondary-provides electrical and hydraulic power.
what chip detectors have fuzz burn off?
all except for engines.
Ohm's law?
current in an electrical circuit is directly proportional to the electromotive force in the circuit and inversely proportional to the resistance.
the number of complete cycles per second existing in any form of wave motion such as the number of cycles per second .
