You want to see some see some ??
no I'll accept your posting it as fact
think you're missing my point though.
your concern is that the carb body or shaft will eventually wear.
It will take a long time for that to wear enough to matter and when it does I'll just replace the shaft or the whole carb, they cost $35, I don't care
If however the throttle shuts unexpectedly and crashes the helicopter it will cost hundreds of dollars to repair.
keep in mind its possible for a servo to fail on its first flight.
Antique does not miss much....its best to leave the spring on carb shaft. If you servo fails, the heli may be running enough tp put it down safe. You should pratice auto-rotation to land if engine does stop. My friends can do it easy with the Helies they have.
