There is no longer a Robinson flight school in Colorado. Exel used to be in Denver then Boulder. They no longer do any training, just hevi lift with the 214b.
There are 4 flight schools in the denver area. 2 H300c schools and 2 with Enstroms. The one 300 school has a couple of instructors who work/worked up at the HATS center in Eagle.
Rotor of the Rockies, Highlander helicopter Flight Training, Denver Helicopters and the new enstrom guy...
I heard a rumor a guy wanted to start a R44 school in Grand Junction.
Hope this helps...
Personally, learning to fly at that DA is going to be hard. Espically if you weigh more than 180 lbs. You and an instructor who weighs 180 doesnt leave a whole lot left for fuel before you hit Max Gross Weight.
Unlike some of the Schools elsewhere out west that are high, you cant go down in DA quickly, just up...
IMO a R22BII up here would be pushing it, especialy on a hot day in July....
Hope this helps
