Crosswind Limits, Bladewashout, and Tangovictor. Where were you when I needed your help (Learning to fly in the USA)?
Waveydavey. The chaps on this thread have had the decency to tell it how it is. Hallelujah. The US can be a great place to learn to fly. I know because that's were I learnt. My advice would be to thoroughly research your school of choice and then really make the most of your training once it commences.
In my opinion, two weeks is way too short a length of time to complete the course. Three weeks is pushing things.
Good luck.
