Hey guys I just finished setting up a HC3sx on a rave 90env. I'm still in the hovering stage and I'm curious which way I should set up this bird for beginner flights. Could someone please explain the differences between the two? I'm programming this on a futaba 8j so I have a little VR knob that I can program it to adjust the tail gyro in real time. Any suggestions would be helpfull. Thanks

Heading hold is the norm
Brian James had a really good explanation on setting up the gyro.
(http://www.heliproz.com/articles.as...icks&article=18)
The following info is taken from that write up.

In "heading hold" mode the gyro takes control of the rudder servo, holding a heading (yaw direction) until you give the tail a command. This kind of gyro really has allowed 3d style flying as we know it now. The vast majority of people do all of their flying with the gyro in "heading hold" mode. So why do we still have "rate" mode? Initially setting up a helicopter in "rate" mode allows you to optimize the tail mechanically with no drift.Some people that fly scale helicopters or people who fly airplanes "right stick only" might like the way the tail "weathervanes" behind the model, but those people are few and far between.

My main reason to use rate mode is to correctly set up tail . Heading hold will hold but constantly strain servo and cause failure . Setting up in rate mode allows you to track tail which gives you a more effeciant and positive feeling tail and no servo failures .

I stole it ,flew it and gave it back ;)

For me I set up Non gov and non heading hold in Normal mode. That why I get a feel for every thing before I pop in to idle up which turns on the Gov and HH.

On the Helicommand rate mode is typically used to mechanically trim the tail for no piro in either direction, then you switch to HH mode and leave it. I would also recommend not putting the tail gains on a knob, set it on an aux channel and adjust the gains for rate and HH mode directly with end points.
