The turbine is a great improvement, but the fact remains that it is a modified airplane and it has a few problems. The engine is canted down 5 degrees, this was done to improve stall recovery however when combined with other otter design features, such as a huge vertical stabilizer, short floats and enthusiastic pilots, the aircraft is a real bear to turn downwind.
Depending on the wind speed, any floatplane can be a bear to turn on the water. I have had many days where the wind has prevented me from turning downwind in a 185 or a 206, even with their smaller tails. That's why god invented sailing. By the time a pilot gets into an Otter, one should hope they are proficient in the very basic art of sailing a floatplane. I'm unsure as to what effect the cant of the engine would have on turning ability

If I'm not mistaken, Polish Otters have this as well. The increased horsepower/thrust means the slipstream beats the tail with more force.

Actually, I thought that the point that most bushplanes were designed for was to get into the air in the shortest distance possible and travel over terrain impossible or extremely difficult to traverse by ground. Speed on the water is useless when all it does is take you into the trees at the opposite end of the lake fast. I'll gladly sacrifice 20mph over the ground if it means I can take off 1000' shorter and climb 500fpm faster to get away from obstacles and not much out there can compare to the de Havilland wing when it comes to those terms.

Well first off, it's illegal to fly floats at night. Second, a big reason for the popularity of the Caravan, could be it's relative ease to fly. Essentially it's a 206 on steriods that you don't have to worry about shock-cooling. Also, it's not a taildragger. Not too many pilots any more have the experience or ability to fly a tailwheel, IMO.
1prop2floats wrote:As for engine problems the Otter(turbine) and the Caravan have the same basic engine.
Actually, there are, if I'm not mistaken, no less than four potential engine conversions for the Otter.
1prop2floats wrote:Icing, well I have'nt tried it but I can only speculate that an Otter and a Caravan would fall out of the sky at about the same time in an extreme icing encounter.
The Caravan's icing capabilities are well documented. I have witnessed standard Otter's returning from trips with icing amounts that scared me just to look at. I can only assume that the Caravan, with it's poor icing track record would not have fared so well.
1prop2floats wrote:And to top it all off, I have been to a lot of funerals for pilots and passengers of DH products and none from a Caravan!
Well, there are alot of potential DH products that have been around for alot longer than the Caravan. I personally think that DH makes (made) the absolute finest of bush planes, far superior to Cessna. Perhaps that's because DH products were purpose built for work in the bush, whereas with Cessna products, work in the bush was an afterthought. I certainly hope you're not suggesting that DH products are dangerous. Personally I don't know anyone who has perished in a DH or a Caravan, but I know a couple who have in Cessnas.
