As an expert builder using the grace that God gave me, I laid the foundation, and someone else is building on it. But each person must be careful how he builds on it. According to the grace of God given to me, like a skilled master-builder I laid a foundation, but someone else builds on it.
The most-advanced helicopters can fly up to 300 miles before having to refuel. How long any particular helicopter can fly without refueling depends on the size, weight and age of the helicopter.
You can begin at any age, when you can reach the flight controls and there is no upper age limit. You must be 16 years old to fly the helicopter solo (by yourself), 17 to get a Helicopter Private Pilotâs Licence (PPL) and 18 years old to get a Commercial Pilotâs Licence (CPL).
