Im taking a ground lab class on the DA42 started yesterday my multi commercial. Ill ask the instructor about the special reqs for instructing, but I believe you need to obtain a check out on this specific a/c to instruct, as for the systems they are pretty insteresting and fancy. this is the only light (very light) twin I know that your maximum takeoff weight is alot greater than your landing weight, compared to the seminole its single engine rate of climb is horrendous- we were playing around with numbers and at 3700lbs @ 25 celsius it was somewhere around 170fpm.
