Translations:KAVAN Pilatus PC-6 Porter - Instruction manual/31/en

Open the throttle and allow your model to gain speed until it rises onto the step of the floats. Leave the elevator at the neutral position; do not apply the up elevator until the model actually gains the take-off speed (a little bit bigger than with wheels). Gently apply the elevator. Do not force your model into a steep climb or sharp turn. The increased drag caused by the floats makes your Porter respond more slowly. The level flight also requires a higher throttle setting. Allow your model to climb to a safe height (50 m or so), and take your time to get the feel of your new floatplane. You should try a couple of landing approaches - at first at a safe height, and at a low level later.
