How to Take Off a DHC-2 DeHavilland Beaver Floatplane Seaplane  

That's the flaps. They're hand pumped on the DHC-2.

Looks factory fresh. Needs to get some hours on it to acquire the usual scratches and scrapes

Those are the trim wheels. He's adjusting his elevator trim as the plane builds up speed and "steps up" out of the water. You generally start your takeoff run with the elevator trim set to full back.

Can’t speak for the Beaver but trim is typically used to relieve control pressures from the elevator. Let’s say you’re cruising along with 80% of your power setting, and you increase the power to 100%, the nose of the aircraft will have a tendency to go up. If you wanted to continue cruising at the same altitude and not climb, you would have to put forward pressure on the yoke to compensate for the increase in power. Following that, you’d set the trim for more “nose down” so you don’t have to hold forward pressure in order to maintain your cruise. For approaches the same is true, you’re reducing your power setting in order to descend, but if you just reduce power and configure the aircraft nose down it will maintain airspeed, so you reduce power and also pull back on the yoke to invoke a “nose up” attitude which will reduce airspeed until you reach the airspeed you need to land. You trim then so you can relax the controls and maintain airspeed without having to continuously maintain pressure on the yoke. Again, never flown a beaver (nor am I rated in Seaplanes) so maybe he’s trimming the rudder, in which case I’m unfamiliar and unqualified to speak. Hope that helps man!

@@Crustmajor thank you!

Da Epicenter , it’s a much tougher and well built Airplane with a 450 horse power engine with a max takeoff weight of a almost 6000 pounds. It basically does the job of 3 Cessna 172’s.

And they don't make them anymore.
