› Normal throttle curve?

I have been thinking for some time about my throttle curves. I have been flipping into idle 1 when I am ready to fly and not using normal due to the fact that when I go to low stick in normal the esc soft starts. I use the set rpm gov setting in my cc ice, so I was thinking about setting my normal th crv at 0% for all points as an added safety measure. Makes sense to me to do this, how many others do this? I have the timers in my tx set to come on when in idle 1 and 2, gyro set to rate mode in normal and th hold, and HH in idle 1 and 2. just seems like the logical thing to do.

With set RPM mode on the Castle ESCs, your normal mode becomes your first set speed. Castle advises approximately 30%. But it doesn't really matter as long as its above 0% and below 50%. Perhaps a better alternative is to enable the auto-rotation mode, in which normal mode becomes power off and throttle hold is use for fast spool up. There are good instructions on this feature the Castle subforum on RCG. Look in the stickies, top of the page.

I have auto enabled, but in normal mode if I put the stick all the way down (0%) it soft starts again. I used the vieos on the cc site to setup auto rotation, and they where very easy to follow. I never use normal mode except to get the rotor moving, and when it gets going I flip into idle 1. I have all my modes set to same rpm for now. Pitch curves are the same for all modes as well. I guess what I am getting at is if I set 0% for all points in normal, then I wouldn't need to disconnect the wires from the motor to make any adjustments to my setup, but maybe not? Too much time for thought while waiting for my packs to charge I guess?

With the Castle autorotation enabled, the startup process is different than you are used to. You start (slow spool up) my switching from normal mode to stunt1 or stunt2. For this to work, the normal mode curve values should be all zero. Normal mode becomes your new "startup mode".

I very much like the start mode in the cc ice. But the startup is the same if I advance throttle in normal mode or just flip switch to idle 1 or 2. if in idle 1 or 2 and th hold switch is flipped and then switched off motor comes back quick. If in normal mode and th hold is used and then switched off motor comes back nice as long as stick isn't at full low. If flying in normal mode and I want to decend and I lower the stick all the way, the esc goes back to soft start mode and I get in trouble. I discovered this about electric helis after my 3rd pack. Since then I have been flipping into idle 1 before even moving the throttle stick. I am used to the nitros I had in the past, as long as the engine didn't die and the rotor rpm hadn't slowed too much, the engine came back no matter what. So far, i am liking elec much better, but I am sure a gasser is in my future!

In set RPM mode the throttle position does not act like a regular thottle. The throttle position is only used to tell the ESC which headspeed you are requesting, 1 2 or 3. A throttle postion of 0 means throttle off. Any thing between 1% and 49% means set RPM #1, anything between 50% and 100% means run at set RPM speed #2. Anything above 100% is set RPM speed #3.

In normal mode you transitining from throttle off to set speed #1. This is bad because to stop the motor, you have to been in normal mode with the stick all the way down. If you are going to use the auto rotate mode, all values for normal mode should be zero. I don't know how I can be any more plain than that.

You don't need to be any more plain and simple. It seems to me we have been on the same page just not said the same way. I love the gov settings in my esc.
