Silly Question
Aren't Ground Handling Wheels meant for handling on the ground and should be removed before flight and stowed safely in the hold if it is intended to take them to another location.
My recall of ground handling wheels on several skidded helis was that they could be retracted and held in the up position by a very tenuous locking arrangement which was only meant to be used to keep the wheels attached for quick access when in the hangar etc.
Maybe manufacturers have improved fittings and they are now approved for remaining in place for flight??
Just a thought or two.......
