"The airfield they work from is at 3500ft so you will get actual limited power operations"
You're funny bomb. What you meant to say was they fly underpowered helicopters that are not up to the task, forcing the poor student to fly right up to the power limit all day long without any safe margin.
Reminds me of the Rotorway factory 'flight school' in Chandler, Arizona. There, in the summer, instructor and student can often only get airborne by scraping their toy along the taxiway, searching for ETL.
It's like saying: "the airfield is located above the Arctic Circle so you will get actual adverse weather operations". It's great to learn how to deal with high DA or bad weather, but not when you just want to get in one R22 flight every day and learn how to fly it.
