I agree with all of the above, Currently Instructing on HR200 (p/t) as well as PA28 and C152 I add the following.
I find teaching slow flight or reduced cruise speed much more difficult in the HR200 than in the 152. The robin at about 75knots will easily slip on to the wrong side of the drag curve when you dont want it to.
Our robins have a very stable stall with a little longitudinal rocking/pitching. As said before not good for illustrating the true dangers of the stall that can occur in other aircraft.
If you are teaching all day in the robin when it is hot and sunny, with its lovely bubble canopy a hat and sun glasses are a must, otherwise you may not be feeling upto scatch for that end of day beer.
