Our own Joe Hudson performed this test. It's quite a big one, over one hour in length but Joe went through a meticulous checklist and put the Huey through a series of demanding tests. Even if it's a long video, it's quite entertaining and interesting to watch if you are passionate about helicopters in general.
You can see other accuracy videos (and data) over at Pro Flight Trainer's website.
