RE: Flaperons or spoilerons
My personal experience is that if you have enough elevator throw and enough power you dont need any aileron mix to do waterfalls. The mix makes up for a lack of one or the other.
I was dead serious about the same for elevators and dealing with wingrock. My Edge wants to wingrock like hell but I have found that after hours and hours and hours and hours and hours of time on the sim and practicing with my plane I can stop the wingrock on my own without the spoileron mix. The key to doing good clean 3D maneuvers is paying close attention to detail in your setup and how you fly your plane and burning copious amounts of fuel on a regular basis. The trick is knowing your plane and making corrections BEFORE a problem begins and not waiting until you see it and then correcting.
Case in point for me,,, I bet I have done 10000 rolling harrier circles(not exaggerating) just in the last 3 or 4 months and Im still not satisfied with the way they look. You cant just know the control sequence, you have to input the controls at the perfect time with the perfect throttle control. The more you practice and get comfortable, the more you can see the little mistakes you are making. As you are perfecting those mistakes your brain is working faster and you begin to see the even SMALLER mistakes you are making. And the funny part is looking at back at what seemed impossible 50000 Rolling Harrier Circles ago is automatic.. And the challenge for me, all that practice and Im just your average pilot when it comes to producing clean rolling harriers, and the other 3D maneuvers, they arent really anything special, Im just beginning to make them look like I sortof know what Im doing.
And I can barely hover because I havent practiced enough.. Sure on the sim I can hover like Mark Leseburg but I havent worked on my hovering all that much. I can do it, but its sloppy. I suspect that after about 20 tanks of gas dedicated to nothing but hovering I will be getting ok at it.
