I am just getting into 3D and just doing some basic roles and flips and inverted hovering at the moment. I am running a Turnigy E500 6T 4000Kv 200W motor with 11T pinion.

I was wondering what throttle and pitch curves everyone runs? I do not have a tach to check my head speed but I think it is pretty good. I actually had to take the 13T pinion off and put on an 11T as the head speed with the 13T was ridiculous and it seamed like the heli was going to explode.

I am running 100% all the way across but not sure if I need all that power and figured I could get more flight time if I reduced it to something like, 100,90,80,90,100. I am doing 0,25,50,75,100 for pitch. I get about 11 deg +- pitch. I think my swash mix is 70%.

Should I do a curve on the throttle until I am doing more power demanding maneuvers or just stick with the 100% across the board? Or is a curve on the throttle better all around?

I have heard by doing a curve (100,90,80,90,100) on the throttle it is easier to maintain a constant head speed because when you punch it the head speed wants to drop but since the throttle power goes up at the same time it compensates and maintains a more constant head speed. Is this better than running 100% across the board?

If I say duck, I'm not talking about a bird that quacks!

i prefer to run 100% flat because if you start changing your headspeed around mid stick and your doing 3d its harder for the tail to combat the changing motor rpm and blade force... plus everything is more efficient at 100... i would say if you have been flying at 100 just stick with it
