the "blue ray" 450 is basically a trex clone with a few minor differences that don't make much difference. Do you have fly bar weights? Also you can put the ball link balls closer in on the servo horn, reducing input throw and taming the cyclic response down a bit. Also Finless Bob made a great set of videos for the trex 450 and he went over all the swash leveling opperations. you could find them by putting: finless bob ccpm videos, into google. good luck!
