No offense, but please find someone local to help you before you or someone else gets hurt... Do you need idle-up for forward flight? No, not really, but that bird should never even be started without throttle-hold and throttle-cut set up CORRECTLY... Throttle-hold keeps the throttle servo locked at a position where the clutch is disengaged REGARDLESS of where the collective stick is... Throttle-cut is obviously used to kill the engine.... Seriously, I'm really not trying to be an a$$, but you really do need someone to take a look at your setup and go over some of the very basics with you... Believe me, even if you had to drive a few hours to meet someone it would be worth the trip, but I guarentee there are lots of others flying helis in atlanta...

Throttle hold is used to "de-couple" the throttle from the collective. This allows for a setting where the engine is at idle, but leaving you with the full collective range. This mode is used for autorotations. You will need throttle hold in case you are forced to do an autorotation, such as if you have a loss of the tail rotor control

Idle-up allows you to have a different pitch/throttle program. It's called "idle-up" since in the old radios the only thing this did was to reset the "minimum" throttle point to a higher point on the throttle. Hence an "upped" idle. Nowadays, most heli radios allow you to program a completely different pitch/throttle curve for normal and idle-up, and many of the radios offer two idle-up flight modes.

The reason to have idle-up is to allow for rapid descents and some aerobatics. While you can do forward flight in normal mode, if your normal flight mode is not set up right you won't be able to get the helicopter to descend without risk. The usual newbie situation is a curve with little or no negative pitch, and a very low idle at bottom stick. The newbie gets some altitude and then discovers the heli won't come down. They drop the stick, and the heli goes to idle. When the blades finally slow down enough to drop altitude, you find it dropping like a rock. You then add throttle and find that it takes a few seconds for the engine to build up speed again. In the meantime... CRASH!

rusirius is right. Find someone local who can help you in person. It's SAFER and much less costly. There's only so much you can get from online advice.

I would add that the throttle Hold is also the place you need to go if you have lost control or are on your way down in a crash. By throwing the TH you drop the engine to idle and this disconnects the blades from the engine, therefore reducing the damage done both to your heli and what-ever it hit's This is a basic drill that needs to be know and used by the newest of flyers,,,

QUICK! ,,,can someone turn the gravity off for just a second,,,,

Just north of Atlanta on I-75N their is a club called Cobb County Remote control. Their web site is http://www.ccrc.info. They are located just north of Kennesaw. I was just down there visiting and they have a great club with some of the best Heli-pilots and the nicest group of guys. Well worth the drive to go check it out and play.
