Guys,
One thing I noticed that has not been mentioned in this thread is the fact that DA engines put out torque accross a broad range. They are designed to have a wide usable aerobatic range. These engines pull harder at lower rpms than any engine I have seen or am aware of. Actually, I don't think they make an engine that runs like they do. You have to ***FLY*** them to understand this. You can load a DA down and it will pull as hard as it will turning way up high. It just won't spool up or accelerate as fast, but it won't bog down and give up in the verticals. These engines are very strong. There is a reason they have the reputation and following they do, and that same reason is why they are selling these things as fast as they can put them out. I don't wanna start a brand war and am not trying to, but these engines are superior in many ways to others made. They are extremely smooth. They have truly linear throttle transition, and the transition is 'click by click' with no blurbs or hesitations or flat spots. The reason these things run the way they do is no accident. They work very hard testing and refining these engines BEFORE they go out the door. Every single detail on these engines has been attended to. They are not the cheapest, but you get alot more when you buy one. Price to me is not even a consideration when buying stuff for my planes. I do not care what something cost. I only care about how it performs and want it to be as trouble free as possible. I know I go on and on about these engines sometimes...yes I do, but these engines are built to a standard that is very hard to achieve...that standard is to be the very best they can be. The guy behind this company also sends us these things for pure love of the hobby. He doesn't just do it for the money (although I know that is important as it is his income) but you can tell that he takes pride in every one of those things that goes out the door. He has a genuine concern for people and wants them to be happy. That to me is what makes this hobby great. People that have concern, and actually care, and want things to 'shine'.
