This could be a real interesting thread(which is good)!
I run between 80% and 100 % on my throttle atv's and try to keep the ball on the arm out as far as it is on the carb.The thing I want is, to have the carb half open, at half stick,or in the"hover range" somewheres as suggested by the engine mfg for a reference point before I set up my throttle curve
The other thing i set up for is,the travel of the throttle, matching the speed of the collective,
I want both to hit top or bottom at the same time.In other words,I want the same transit times on throttle and collective,this way the engine never has to fight to catch up to pitch changes,both positive and negative,and the collective to be at half its travel or half stick when the throttle is halfway open(in normal mode)
The setup in rays may be good for other parts of the heli,but considering theres no load on the throttle linkage,is why i keep the balls out the same lengths on the arms.Running higher or lower atvs on other points of the heli for better resolution and keeping the torque rate of the servo is something I go back and forth with depending on what I'm setting up for,either contest or 3D/sport flying.I say theryre both right,it all depends on what your personal preferences are.....
