you fly a very special piston Islander then Jekijock. The ones that I used to fly (all maintained to a very high spec with no cost cutting) would be lucky to climb on one donkey at max weight above 500 to 1000ft having suffered an EFATO. The drift down chart gives a stabilising altitude of about 2400ft for the BN2B.
Like any twin though it will bite if you simply don't react fast enough to an engine failure and if you are heavy and do not feather that prop then you are not going to come back around the circuit. An Islander has an advantage over most light twins in that you don't have to think about the gear.
