Thanks for the inputs. Inderstand that this is all sequence flying control rates. I've not got into much 3D knife edge stuff (although its the best rolling harrier plane I've flown). The prototype has 14 percent opposite aileron mix with left rudder, and 15 percent right. My initial impression was that its not good and dihedral needs to be taken out. However, even with that mix in, I've never flown a plane that is as linear as this one. I can feel just a little bit of roll during the sides of a one roll circle (rudder on medium rate), but its by far the best flying plane I've flown. Pitch is near perfect. Only about 1/8 inch up elevator with left rudder and 1/16 inch with right rudder. For example during a loop with integrated 4 point roll, adding rudder causes a straight line during transition in the 330 design. Its because although mix is good for knife edge, when the plane is in the middle of a loop, it pitches with rudder as its applied, rolling from pint to inverted during the loop. The JTEC (Radiowave, as now I understand its called) 300 prototype does not do this at all. Is smooth like a pattern plane, all the way through. I can really tell the difference during verical point rolls in a crosswind. The rudder and elevator can be used to wind correct for weather vaning for example, during a roll, with no coupling. This is because of the large forward canopy, giving it a more balance side profile; more-so than the 260 design which has the canopy further back on the fuselage. Here is the clincher. The aircraft actually wants to self-correct on both upline rolls and (somehow) downline rolls. In other words I found that if a down line was off just a bit It somehow corrects itself by going more vertically on a downline. I've never experienced this before and its quite remarkable. In a positive snap going on a downline, the nose pitches up positive during the snap, but at the end of the snap the nose straightens out and wants to point straight down. Maybe its all in the radio setup, as control responses are more like Chip and Jason's setup, but I am not inclined to change, its magic. We will make improvements but right now its flying so well...
