Flat Spot
Grease to be used inside the tail gearbox should be a teflon or
light lithium type of grease commonly found in a hobbyshop.
Do not use grease or any type of lubricant on the remaining
gears on the helicopter because they are exposed and can
actually attract dirt and debrie that can lead to a failure.
