Flips!!! w/Video

And actually, when you do start to use idle-up, you really should change your Normal curve to something more traditional like 0-60-80-90-100 instead of 60-80-80-90-100 so that (if you wanted to) you could have the option of spooling it all the way down without Throttle Hold. If mid-stick and above are same for Normal/Stunt, you should be able to flip the switch back and forth without any effect while you're hovering.

Is there an advantage to that? I am pretty used to just using the throttle hold. Like if and when I do use idle up I would prob just land while in idle up and use throttle hold to shut off.

I don't know. Personal preference I guess. If you were to have an ESC without a soft-start, you definitely wouldn't want your Low throttle setting to be 60. I like to be able to plug in the battery without T.H.; let everything arm; spool it up a bit on the ground to make sure everything's in order. Sometimes I spin it back down to adjust something (typically the rudder trim, as I haven't upgraded the gyro yet); then spool it back up again. Sometimes I just let it spin on the ground at around 1/4-stick (50% throttle in my case) while pedestrians pass by, or perhaps even spin it down all the way. Sometimes I use T.H.; sometimes I use 0-throttle.
When I first started flying a standard Normal curve, I liked how it slowed down nicely when landing. When I first started flying idle-up, I would always flip back to Normal for landing, as I was afraid to land with the head spinning that fast. Since then, I've gotten comfortable landing in idle-up -- with or without hitting T.H. -- but I still like having the option of throttling all the way down to 0 without T.H.

okay thanks for the thorough explanation.

No problem.
Eventually I would like to get my idle-up curves set up for a faster head-speed than Normal mode. That will require a bit of work on the Normal pitch curve so that there's no jump when switching modes while hovering.

Shouldn't all 3 pitch curves be the same? I have all 3 of mine as linear 0-25-50-75-100

Not necessarily. Remember, the "standard" Normal pitch curve is something like 35-42.5-50-75-100. This roughly tranlates to -2*/0*/+10* pitch. If you want to be able to have different head speeds for different Flight Modes (and not have a huge jump when switching Flight Modes) you may need to tweak the pitch curves (specifically, the 3rd and 4th values) slightly. Radios like the DX7 that have 3 Flight Modes you can set up so the transtions (N/I1/I2) are less severe. With the DX6i and only 2 Flight Modes, if I want my idle-up to have "max" head speed, I'll want a throttle curve something like 100-95-90-95-100. But if I want my Normal mode head speed to be significantly lower, I'd want a throttle curve something like 0-40-60-70-80. If I'm hovering at around 65 and flip to idle-up The motor's going to try to jump to 92 (without the benefit of slow-start), which in addition to the huge torque bump, would shoot the helicopter to the moon if the rotor pitch didn't also change. If the throttle jump was combined with a corresponding decrease in rotor pitch, you could (in theory) maintain your hover. Now, that's a pretty severe throttle bump, and the heli would probably piro wildly (without a GY401;) and JR3400G) from the torque; but it's an example.
