Because the Seneca 3 is turbocharged, I certainly have found the it takes a little getting used to. Gives you more to think about because of the double whammy of increased lag and the ease of overboosting. Basically a smooth measured approach is a must for go-arounds and practicing stalls, etc. Plus, I found the throttle very sensitive too. A little touch can loose or gain a few inches
Not quite as touchy as the Turbo Arrow though.
Handling is, heavy but a sinch really. Only just started my MER so not a qualified opinion.
